IP Convergence: Beyond VoIP, Beyond Cost Savings - collaboration

Convergence a Foundation to Unified Communications

Mon, 14 Jul 2008 21:38:34 +0000

As with any new technology you will find different opinions of what you should consider and do when deploying new technology.

Recently Zeus Kerravala from Yankee Group posted a blog urging enterprises not to consider VoIP as a foundation for deployment. Stating concerns of complexity and that only a minority of enterprises completing their VoIP deployments.

I would like to offer a supportive opinion that can be found in a whitepaper that my peers and I have recently released. You can download a copy here.

The whitepaper is based Global Crossing’s experience of deploying Microsoft’s Office Communication System within our internal IT infrastructure as well as recent market data.

Global Crossing was successful in deploying a Unified Communications platform (text, email, video, voice and data) within the last 24 months (Live Communication Server in 2006 which was upgraded to Office Communications System in 2007) based on efforts which were completed in 2004.

In 2004 , Global Crossing deployed an internal network infrastructure (LAN and WAN) that was capable of providing convergence of Voice, Video and Data. Not only did Global Crossing deploy a network, more importantly we broke down the traditional silo’s found in IT departments across Voice, LAN and WAN teams.

This foundational element enabled application layering (VoIP, Video, Data) that is available in our full featured Unified Communications platform today.

Enterprises considering a Unified Communications deployment will need to deploy a stable, converged network in conjunction with a presence enabled framework.

VoIP Considerations for IT Decision-makers

Tue, 27 May 2008 12:59:27 +0000

There was an article in Processor Magazine that starts to address some points that should be taken under consideration for IT managers looking at packetized communications for their Enterprise. Below are the highlights and my thoughts:

Look For SIP Support
I couldn’t agree more! SIP is a protocol used to establish, teardown, modify, etc communication sessions. It’s very diverse and relatively simple when compared to past mechanisms. Most importantly, it has become the defacto standard within the world of telephony. There’s native SIP support in nearly all the major vendors that supply VoIP gear. (Cisco, Avaya, Siemens, Microsoft)

Consider The Benefits Of Hosted PBX
This topic has be discussed numerous times in the past, and even before that within a TDM context (PBX vs. Centrex). The thing that’s different within an IP context is the feature and functionality available. When comparing a PBX to a Centrex offering, one key difference was additional feature and functionality in a PBX. Centrex offerings didn’t have the same "whiz-bang" features. In today’s Hosted Telephony offerings, there’s near feature parity, so the key determining factor becomes cost of ownership.

Think Unified Communications
VoIP (or Telephony) MUST be seen as a stepping stone to the ultimate goal of Unified Communications. IT managers should consider the roadmap to UC when choosing a Telephony solution. Real-time communications need to become multi-modal, meaning there should be options to transition communications from IM to voice to video to online collaboration on a document, and then back again - all within the same context and within a common look/feel.

Traversing NAT
Though the issue of Network Address Translation (NAT) is well known to negatively impact SIP sessions, the real point for consideration here for the IT Manager should be around considering the deployment of a Session Border Controller (SBC) within their Enterprise as part of an overall design.

Know & Apply Codecs
There are more ways to packetize voice and video communications than one can shake a stick at. The author points out the predominant technologies of G.711 and G.729. Issues of bandwidth consumption and quality of user’s experience must be balanced. Generally speaking, the more bandwidth consumed, the better the experience. But the more bandwidth used, the greater the cost to upgrade the LAN/WAN infrastructure to accommodate. If you skimp on cost, the result would be poor quality, and then adoption and experiences would suffer. It’s a delicate balancing game.

Some further comments captured in the article..

• Make sure to have 100k in bandwidth free and available for every conversation when determining whether the enterprise really has enough bandwidth for VoIP, according to Andy Abramson, blogger at VoIP Watch and founder and CEO of Comunicano (www.comunicano.com). With this understanding, it’s easy to see that DSL or a cable modem line won’t cut it.

• Get VoIP phones that are both wired for Ethernet and wireless for Wi-Fi connectivity, notes Abramson. “That way, people can wander, and all internal calls within the building are free of charge because they stay on the network.”

• “Make sure the vendor is going to be around to support the purchase,” Abramson says. An older vendor with roots, commitments, and financial means is an obvious choice. A new vendor with strong management, skills, and reputation who proves out through considered research can also be a sharp choice.

VoIP and IP Telephony - The Benefits Revisited

Fri, 16 May 2008 01:29:07 +0000

Over the past 14 months i've met with many different customers at many different levels. One thing I continually do is talk about the benefits of converged technology such as VoIP and IP Telephony. The last few blogs have leveraged convergenced as a foundation for unified communications as a next generation service offer but in this post I thought I would try something different and revisit the benfits of some common technology - VoIP and IP Telephony.

Most people understand the benefits of transitioning to a converged all-IP environment. As more applications come onto the market and the technology proves itself, these firms will be able to avail themselves of the many benefits of such converged technology adoption.

So why consider leveraging VoIP and IP Telephony?

· Offers advanced call routing and enables new applications to further customer service initiatives.
· Accelerates and facilitates the move from a legacy environment to converged networks.
· Anchors IP innovation across the enterprise, and helps deploy a web services infrastructure enabling rapid development of IP-based applications and services.
· Facilitates the deployment of real-time workforce collaboration tools, which fosters an environment of high worker productivity, innovation and information sharing.
· The market isn’t moving towards converged networks – it’s there! Therefore the adoption of IP and VoIP are foundational steps on taking you down that path.

What are the benefits of VoIP and IP Telephony?

· Voice over IP can bring customers the benefits of network optimization and greater value through the convergence of services over a single connection. One IP network will handle data, video and voice.
· It can reduce total spend on traditional telco services by converging voice and data onto one pipe, eliminating the need for leased line charges from a telephone service provider, since all calls are flat rate.
· Depending upon the design all calls may be on-net as is the case with Global Crossing’s VoIP Onnet services. Compared to traditional TDM solution with the exception of private voice networks the majority of calls may be delivered off-net and thus more costly to operate from a call perspective. Fully converged services extend the on-net “look and feel” through our enterprise VoIP network. Instead of building their own TDM networks and deploying proprietary on-net calling plans, customers will gain value by leveraging a service providers VoIP network such as Global Crossings.

IP telephony adoption also delivers the following benefits:

· It can help lower cell phone charges by enabling worker productivity on the road and remotely.
· It reduces high toll, long-distance usage.
· It facilitates real-estate consolidations through extension and directory mobility by leveraging VoIP with “find me follow me services”.
· It reduces PBX support issues by migrating to fully converged network-based services that are centrally located.
· Packet-based voice traffic becomes just one application running over a multi-service network, allowing for more efficient bandwidth utilization.
· With dynamic bandwidth allocation technology in the absence of voice traffic the full network is available to data traffic.
· The move to IP telephony is a good first step towards convergence, and allows for more sophisticated network management by running voice over an existing data network.

What are the possible challenges in deploying VoIP and IP Telephony?

· Converged networks can be more complex to operate – the LAN’s additional complexity needs to be managed. This complexity can be offset through a managed VoIP solution.
· The business processes associated with troubleshooting and managing network quality need to be well-defined.
· Depending on the age of the network already in place, the transition to IP telephony may require some additional costs associated with hardware requirements such as advanced telecom gear to replace older equipment as well as replacing the end telephone stations used for traditional telephony with advanced IP-enabled sets.
· Additionally, if power over Ethernet is chosen there may be additional expense associated with powering the handsets.
· Finally, VoIP requires advanced traffic management and statistical analysis on edge and core components in order to track and trend network utilization and problems appropriately. Such systems may not necessarily be in place which would require further network management software to be deployed.

There you have it .... some of the VoIP and IP Telephony benefits revisited. There are cetainly more but those are just a few that I captured this evening.

SIP Decentralizing Enterprise Communications

Tue, 01 Apr 2008 18:09:03 +0000

Of the more interesting developments that are emerging as SIP technologies and products mature is the changing context that Enterprises’ IT organizations operate in. Historically, telecommunications has been defined and provided to the marketplace by Service Providers like Global Crossing, Level 3, BT, etc. The requirements needed to formulate an offering were provided by SPs to the manufacturers of the platforms (Cisco, Juniper, etc). Things are changing rapidly on this front though. Enterprises in some cases are bigger in many aspects of the definition than some smaller traditionally defined Service Providers. In my humble opinion, this warrants of new definition of the Enterprise. The Enterprise is the newest category of a Service Provider.

With regards to SIP, there is ample evidence of its adoption in the Enterprise marketplace and vendors that have catered directly to Enterprises have taken heed. As examples, see Microsoft’s, Siemens’, Cisco’s, Avaya’s adoption of SIP in their product portfolios.

The impact of this is an overall decentralization of the Enterprise communications environment that leads to a more collaborative workforce. If you need some examples, think of the IM communications in support of standard telephony and email infrastructures. Nowadays in our MS OCS/Exchange environment at Global Crossing, when I read an email – I not only have the ability to reply, but IM or click to call in response. This is all handled via a single user interface. This form of collaboration is _NOT_ dependant on the traditional services that Global Crossing provides. (with the exception of the underlying IP transport), but rather the infrastructure is supported by our internal IT department. By the way, this is all decentralization is enabled with SIP.

IP Convergence: Foundation for Unified Communications

Thu, 06 Mar 2008 20:48:39 +0000

I had the opportunity to present the latest message from Global Crossing in support of Unified Communications. On March 27th, I attended a panel discussion at Sun Microsystem's Boston campus for masnetcomms.org and on March 28th I presented at a Global Crossing VoIP seminar in Cleveland.

My massnetcomms presentation was focused on the technology enablers (Simple Object Access Protocol (SOAP), XML, Service Oriented Architecture, Price performance of general purpose computers , Software As a Service model, Network Convergence (IP and access), Protocol Convergence (SIP)) that have created the opportunity for Unified Communication adoption. Unified communications is not a new concept, it’s about 10 years old and really never took off. The early UC models were all hardware centric with specialized devices and lacked seamless integration into your desktop. However today, companies like Microsoft have taken a software only architecture that leverages their installed base of email (exchange) and identity (Active Directory) into realizing a seamless experience on my desktop.

In Cleveland, I shifted the discussion to a more network centric message and highlighted our internal IT success in deploying Microsoft OCS . Global Crossing’s internal IT team began the road to Unified Communications in 2003 when we deployed Cisco VoIP handsets .

The 2003 VoIP deployment was an important milestone in that both the network (LAN, WAN) and operations (Voice vs. Network team) had to come together and provide a reliable and consistent transport for Voice, Video and Data. This is an excellent example of IP convergence providing a solid foundation for our subsequent deployment of Unified Communications.

In 2005 Global Crossing deployed Live Communications System (LCS) (LCS is the predecessor to Office Communications System (OCS) ) and in 2006 our first deployment in support of Microsoft OCS beta. Global Crossing was one of 72 companies supporting the beta and tap phases of OCS and in October 2007 supported Microsoft with their OCS launch in San Francisco.

What we are experiencing is that not only can OCS provide unparalleled integration into our desktop environments, but more importantly business transformation as it is now embedded into our workflow, sales portals and company directory. We are able to work more efficiently , with better communications which will add to a better customer experience.

But the deployment of Unified Communications didn’t start in 2005 when we deployed LCS, it actually started in 2003 when we began deployment of a converged network.

At both presentations the message reasonated with other industry leaders and customers. Clearly IP and network convergence provides the foundation for a successful deployment of Unified Communications.

The Value of Presence ? That is the question.

Mon, 05 May 2008 13:13:38 +0000

While visiting with several individuals a few weeks ago at the Ziff Davis Unified Communications Summit in Seattle, WA I noticed that some people hadn't yet realized the power of one aspect to the overall value of unified communications which relates to presence awareness. That is leveraging presence not just in instant messaging but in other communication vehicles can play an important role in transforming your business impact as an IT organization. As a result I thought I would dedicate this post to help create ideas around things that can be done to assist in helping IT in leading the way.

Here at Global Crossing in an attempt to leverage this core components of Unified Communications in an ongoing effort to incorporate the advantages of collaborative, converged services within our enterprise we've transformed internal applications from static non presence aware to anticipatory engaged communication tools that are supporting contextual collaboration with presence-awareness throughout the enterprise. In this instance presence-awareness (whether someone is available in simple terms and how to contact) is utilizing capabilities including chat, computer-based telephony, conferencing, IP video, and e-mail across tools that leveraged across the enterprise drive in principle more efficacy from consumption and corresponding execution. In fact it is my opinion that since presence has been embedded into our application infrastructure to enhance our collaborative capabilities it is natural to see transformational improvements occur around our "quality of experience" associated to the overall user experience. This is so because enabling enhanced customer experience truly enables the IT organization to drive one more component to our IT organizations transformational success in enabling the business to not only "react" but be proactive by achieving extensibility required within the distribution transparency model required for execution. Said another way the fact that presence awareness has been integrated into our application infrastructure means this action will further enhance our agility to enhance operational efficiency by allowing application "pivots" to be present thus accelerating communication by eliminating in some instances serial cognitive task execution.

As the industry landscape continues to evolve there are a few constants that will remain the same: (1) increasing business demands require more innovative, transformational capabilities between employees, partners and customers and (2) continually driving operational velocity reductions around the cost basis of delivering information technology services is imperative. It is commonly believed by many vendors such as Avaya, Cisco, Intel, Nortel and Siemens as well as software developers such as IBM and Microsoft that presence technology will continue to become an increasingly important tool at driving traditional costs out by attacking the serial nature of traditional work execution thus increasing operational efficiency.

So why is presence so important to Unified Communication services? Presence is important because it can become the intelligent communication application for converged IP communication services such as those demonstrated by our IT organization at Global Crossing. Determining where a user is and how best to reach them in our case by leveraging presence enabled applications that have been integrated into our infrastructure with the "glue" to increase the overall value of our converged IP services brought to the table and help realize substantial business transformation value.Said another way presence-aware applications offered on a converged IP communication service help evolve traditional serial actions of quickly determining and thus engaging with employees regardless of location, modality or scheduling which allows our globally dispersed users to communicate and collaborate in real time providing productivity in a truly global and mobile workforce environment. Combined converged IP communication services with presence technology provide for accelerated collaboration between our employees, partners and customers by knocking down the walls of traditional serial communications and by accelerating communication through anticipatory engagement.

Presence is the value.

UC going good to great

Thu, 15 Nov 2007 20:00:11 +0000

At some point or another when the concept of unified communications comes up during customer interactions, dialogs with colleagues, strategy discussions - often times it moves to a discussion around features and RFCs and remains there. Having come from an IT organization for which I was immersed for several years in operations I have a different perspective when I think about unified communications. When I think about unified communications I don’t think just about SIP or SIMPLE or the ability to receive communications across multiple modalities rather I think about the constructs that make unified communications possible. Don’t get me wrong – the ability to communicate across multiple modalities simultaneously such as cell phone or a software based agent using a simultaneous ring or find me follow me feature is intriguing and to some extent are becoming increasingly more prevalent in a “techno gotta have evangelists” world such as my own but it’s not the only place where unified communications is making IT operations go from good to great!

What I see as taking unified from good to great and where truly exciting work is happening is where software and network architects alike focus not on the “features” alone (although continuous improvement is important) but rather on making unified communications seamlessly integrate into existing IT environments thus allowing IT organizations to drive further value from legacy / existing investments and hopefully simplifying their operations experiences. An example of how this might occur is in and around identity management and enhanced directory services where a users identity can be defined within a unified communications model that not only allows that identity to transcend one modality to another but also might be the same identity that is used for all application access requirements. This my friends is where some of the real magic and exciting stuff appears to be occurring and what is going to make unified communications go from good today to great tomorrow when mainstream adoption across IT organizations occur so long as business justifications and associated ROI necessary for the investments are realized.

That said many vendors today offer unified communications with heavy emphasis on SIP and SIMPLE for obvious reasons – to drive market penetration for current or future products as well as to protect the cannibalization of their installed base through next generation service expansion. What will be interesting to see unfold is not what service or features come next but how many of those vendors look to attack a core and longstanding issue of IT pain points – enabling unified communications while seamlessly integrating into existing back office infrastructures. The key to success in my opinion and those who are positioned for success will be how vendors use a single identity to authenticate and gain access to different modalities such as email, voicemail, enterprise instant messaging and collaboration software or web based tools thus allowing the ability to transcend multiple modalities seamlessly and transparently while affording productivity improvements that every CIO is asking and requiring. In my opinion unified communication can’t be yet another off the shelf solution that requires more work to integrate into an environment to become productive but rather it is about enhancing the bottom line – getting something more for very little and driving tremendous productivity gains. So to be effective and win market share such companies that offer unified communications must invest heavily on seamless integration to the back office and thus driving a core fundamental of productivity that unified communications anchor on.

So no new user names, no new user accounts, rather a single yet pervasive identity in order to make unified communications become great. You could say that the argument or requirement for a single identity isn’t new – rather its been around for a while. In fact there are companies that make identity management software and have been doing so for quite some time. What you can’t say or know and for which I am most excited about is watching how those companies map their current positions in delivering such capabilities into facilitating mainstream unified communications and its adoption further. Food for thought in case you’re not yet following me - watch what IBM and its Tivoli solution, Microsoft with its Active Directory as well as others do with their software around unified communications and how they enable further business communications. Heck, one never knows what Google might do to improve their recent moves into mobile wireless communications since they may see IBM and or Microsofts current positions in this space as a threat to their continued dominance around maintaining their velocity as a formidable competitor whose deep research capabilities rival all but IBM and Microsoft in an industry moving at light speed.

From this former IT guy some real exciting stuff around unified communications is happening … taking it from good to great. Watch how a single, enhanced identity will be mapped transparently to core IT infrastructure services and driving future unified communication services thus making it possible.

Web Services Catching on in Telecom?

Thu, 13 Sep 2007 17:42:54 +0000

OK, so Web Services has been around for some time now. XML and SOAP have been used as an easy to implement mechanism to serve as an API for distributed applications. However, only until the last year or so has web services come to the forefront of telecom services, and I believe it will be used as a foundation for many innovative solutions that will be built under the Unified Communications/Integrated Communications umbrella.

VoIP has traditionally been relegated to basic telephony services in the telecom industry, such as VoIP/SIP Trunking and Hosted IP Telephony services. However, with the advent of Unified Communications (check out the Unified Communications Conference at the Fall VON Show in October), which brings together telephony, messaging, collaboration, data and mobility into an integrated solution, we begin to see services using VoIP as becoming more visual in nature, bringing telephony into web interfaces rather than to phones, and using multiple distributed applications which are blended to create solutions.

Global Crossing has announced that it is providing innovative Unified Communications solutions to the UK Government. These services will soon be expanded to provide even greater capabilities to the Enterprise, and globalization is a key element of this strategy.

Does this mean IMS? Not necessarily. Many solutions in the market have built interoperability through vendor partnerships using SIP from a voice signaling perspective, and Web Services brings another element into the mix which greatly improves interoperability and improves usability. IMS is not nearly as innovative as Web Services, and certainly not as easily implemented. However, IMS can be combined with Web Services to anchor control, signaling, and provisioning of multiple applications in a standardized fashion. My belief is that it will take the industry some time to pull everything together using IMS.

As an example of how web services can be introduced into telephony, clients can be built into web pages using internet API's which use click to call functionality. In addition, web services can be used in a unified communications "Dashboard" interface where a user can view presence status, conference attendance, manage services through voice portals, and trigger entirely new communications business models. Two innovating vendors highly leveraging web services in the telecom space are Sylantro and Iperia, which bring call control and management extended to web communications, and provide visual voicemail and unified messaging services as a solution. Very cool stuff.

Web Services brings easy programming interfaces to industry standard transport (HTTP) to bring innovation to telecom services. As enterprises become more distributed in nature, with remote offices in multiple countries, their key workers are also becoming more distributed and mobile. Telecom needs to keep up with these trends and the increading demand for requirements of the changing workplace with real time communications. This is bringing traditionally separate applications together via Unified Communications, and the "unification" or blending of these distributed applications can use a combination of signaling techniques and web services functions to bring a highly visual element to the solution.

Microsoft OCS at Global Crossing

Mon, 20 Aug 2007 15:16:28 +0000

If you're like me, when one of your internal IT guys gives you a call and asks you if you want to trial some new software, the answer is almost nearly always a resounding YES. Last week Steve Schafer gave me a call and asked if I wanted to try out the new 2007 version of MS Communicator based on the OCS platform. I got set up with it on Monday and wanted to share some of my experiences with it.

There are several new features that I find very attractive:

All conversations are kept and stored in a mailbox. This can be the text of an IM conversation, or if it's a phone call, then the number, name of person you called (if available) and the length of call is recorded.
The IDLE status doesn't obfuscate any other status, but shares the button color so that you know if the person is idle at their keyboard while in a meeting, on the phone, or available. You get a little bit of credit this way for behaving yourself and not multitasking while on a conference call. It might also eliminate a few yt?'s
Multi-party video calls, Ohhhh yeah! Create a multi-person IM conversation and then fire up Video. Whoever is talking at the time is broadcast to all other parties. It works reasonably well for me in spite of the fact that I am a tele-worker with a lousy Internet connection.
Quasi-FMC/UC capabilities that include a DID for your computer, simultaneous ring to another number of yours, voice-mail delivered to your inbox as a .wav file, as well as the ability to call a voice access number and access your calendar and email. I don't suspect I'll ever use that last feature, but it is nice to know that if I was ever having trouble falling asleep that I could have a pleasant female-timbered computer voice read my email inbox to me, which I shall hence forth dub Femail. Copyright! :-)

And there are several things that I predict will be very evil.

All those great mailing lists in the outlook exchange address book now come up on searches with an auto-complete function in the communicator search window. Just when email got so crazy that you had to turn to IM for productivity gains, here come the mass IM broadcasts! Broadcast IM's are bad, mmmkay??? Just say No!
The new color scheme is a bit harsh. The charcoal title bar is fine, but the new 3D shading on the buttons and the traffic-light red/yellow/green availability scheme is kind of hard on the eyes. The other issue here is the connotation associated with red. The previous version showed a pleasant shade of blue when someone was busy, but now it's red. Since I tend to be booked in meetings most of the day, I am always an angry shade of red. That's evil.

Stuff that still doesn't work quite right:

Softphones still suck. I have a reasonably fast laptop and a gig of RAM, but somehow I still have issues coding/decoding when my computer gets busy for a few seconds. Give this program more priority by default. I have a Microsoft IP phone on the way that should resolve this problem, but I'm still pretty shocked that computer telephony doesn't work better than it does.
Video/audio sync in video calls. I've noticed that I receive the video frames before the audio. What gives? Audio should have priority over video. Always! If Video is falling behind, drop the frames. If the audio is falling a second or two behind, wipe the whole buffer and start over or something so it doesn't feel like I'm having a conversation with someone half-way to the moon.

All in all, the new features are pretty cool, and I'm looking forward to the rest of the company getting upgraded to this release.

Virtualization- Part 1 - The Abstraction of the Internet

Thu, 12 Jul 2007 19:00:45 +0000

A key element of virtualization is the concept of abstraction. Abstraction can take many forms and many applications with profound benefits.

This is the first of a five part series on the evolution of virtualization, with the following planned articles:

Virtualization – Part 2 - The Abstraction of the Computer
The definition of a computer (CPU, data bus, memory, input/output, and disk) , the abstraction of programming a computer (machine code, assembly language, 3rd generation programming languages (3GL), 4GL and 5GL), the separation of a CPU from disk and the application of a Storage Area Network (SAN), blade servers and the realization of GRID computing.

Virtualization – Part 3 - The Abstraction of Applications
Concepts of a Application Programmers Interface (API), examples and pitfalls for APIs and the abstraction of Web Services.

Virtualization – Part 4 – Virtualization of Voice Communications
Telephony basics in the circuit switched voice network and the evolution of the packet switched voice network , aka VoIP.

Virtualization – Part 5 - Real World IT Examples and Benefits
The anatomy and benefits of Virtual Data Centers and Call Centers

We’ll start the series on a model that is near and dear to our hearts – the Internet.

Vint Cerf is one of the founding fathers of the internet and created a transport model of moving packets from one network to another. Seems pretty straight forward but, back in the day this was not an easy task as the networks were typically homogenous deployed by a single hardware vendor (DEC, AT&T, NCR, Apollo, Banyan, etc… ). Each vendor had their own proprietary methods of defining a ‘packet’ (that is,   the number of bits in a ‘packet’; the order of the bits in a ‘packet’; the number of bytes in a ‘packet’; and the meaning of each bit/byte in a ‘packet’), and the way these computers spoke to each other (i.e. the protocol).

The first major challenge was to allow these desperate networks to exchange data. The challenge was met by defining common communication protocols (i.e. TCP/IP, UCP, etc …) , and   a common packet & addressing structure.

This allowed high powered users (Scientists at the world's research institutions) to efficiently communicate across an environment largely made up of heterogeneous computers. Within this structure, application developers at each vendor (DEC, AT&T, NCR, Apollo, Banyan, etc…) developed tools, using the agreed upon common protocols , to transfer files (FTP), login into another computer (TELNET) and exchange email (POP3, SMTP).

Tim Bernes-Lee was one of those high powered users and wanted to find an easier way of navigating thru the internet without having to issue ftp commands or walk thru folders ( i.e. directories). He created an abstraction between what the internet looked like and the commands that facilitated communications . Tim created the notion of the world wide web. The world’s first web site was brought online in 1991.

Tim is credited for creating the following words we all use everyday: www, http and HyperText Transfer Protocol.

These abstractions have lead to an unprecedented number of users to the internet in very little time.   A concept that some call, “Internet Time” .

“Internet Time” is defined by Wikipedia   as:

“Internet time was a common catchphrase that originated during the late-1990s Internet boom. In this period, people who worked with the Internet had come to believe that "everything moved faster on the 'net", because the Internet made the dissemination of information far easier and cheaper. Fast-moving developments were therefore said to run "on Internet time".

Efforts in virtualization of the internet are focused in/around layer 3 of the OSI stack, in the next article in this series we will take a dive into the machines themselves to understand abstraction as it relates to their operation and subsequent evolution, in Part 2 - The Abstraction of the Computer.

We’ll then take a quick look at the applications that ride over them in Part 3 – The Abstraction of Applications.

After understanding the abstraction of the Application, we’ll look at a very basis of communications – Voice , in Part 4 - Virtualization of Voice Communications.

In the final article we will put all of these pieces together in understanding the anatomy and benefits of Virtual Data Centers and Call Centers , in Part 5 - Real World IT Examples and Benefits.

Google buying Grand Central

Mon, 25 Jun 2007 14:11:49 +0000

While enjoying my morning coffee and skimming the headlines from the weekend, it appears that TechCrunch broke the story yesterday that Grand Central is being bought by Google.

&

If you aren't knowing what Grand Central is, allow me to priovide a quick run-down. The entire concept is built around the 1-number ideal. Here are some of the features: (from their website)

Screen Callers
Know who's calling and screen unknown callers

ListenIn
Hear why someone is calling before taking the call

Call Record
Record calls on the fly and access recordings online

Block Callers
Unwanted callers won't be able to reach you anymore

Notifications
Receive voicemail notifications via email or SMS

Ring Different Phones
One number that rings different phones based on who's calling

Greetings
Personalize your voicemail greetings by caller or group

RingShare
Go beyond the ring and choose ringback tones for your callers

WebCall Button
Let people call you from a web page without showing your number

CallSwitch
Switch phones in the middle of a call

Click2Call
Call from your addressbook and save your typing

Mobile Access
Visual voicemail for your mobile phone

So why is Google interested in Grand Central? Well think of the possibilities if you combine the above services with gmail and gtalk?!?!? It looks to me that Google is going to be taking Skype on head-first.

Mobile Ads Are On The Horizon

In this day, we are all hit by a constant barrage of advertisements. From the web, email, TV, magazines, radio, internet radio, news videos, and movie theatres we now have an expectaion of an advertising flash suspending our immediate gratification, and have built a subliminal blockade to the best of our ability to focus on the content we seek. I recall the day when I was able to watch a DVD without being forced to fumble through 5 movie previews (I've noticed that Disney is the most aggressive). So when I saw the AT&T comment on the Washington Post regarding the revenue opportunity of mobile advertisements, and the operator's strategy to realize it I can’t say that I’m surprised. After all, unless you have been living in a cave for the past few years, mobile phones are already becoming an Internet utility device for many users.
We’ve already seen some mobile web banners in their early stages by ESPN’s WAP site. However, mobile Internet is still a bit expensive at this point to open up any real opportunity. The Mobile Internet is still primarily used for targeted information searches, based upon 3rd party research rather than simply perusing about.

Many enterprises are examining opportunities to realize revenue in the mobile space, but are in the formative stages of their research. Looking at mobile phones beyond voice, and even beyond multi-modal communication such as FMC is a critical element to the formulation of a broad business strategy. In the next few years, you will probably see popup blockers on mobile web browsers!

Why PS Home matters

Mon, 14 May 2007 17:54:18 +0000

In my last post about the PS Home, I spoke about the Sony announcement of PS Home and how I found the technology interesting.

Unfortunately, I broke one of the cardinal rules of good blogging by completely failing to tie it back into Global Crossing's business. A Hat Tip goes out to Matt Sewell from our Phoenix office for pointing this disconnect out to me.

Immersive, Virtual Reality environments are important to me and to Global Crossing because it points the way to the future of collaboration, which is currently one of our best value-add product areas. Much like the way that pr0n addicts drove early bandwidth usage on the Internet (and were therefore one of the key investors!), Second Life addicts are driving innovation in collaboration technologies, particularly the immersive variety (and are therefore investors in it!).

What we learn from these evolving technologies and how they are adopted can give us clues (but not necessarily direct evidence) as to how the technology may be adopted by the business world.

But before I start thanking SL Addicts for helping realize the dream of virtual reality....

...lets look at what we have learned so far.

Users can get so immersed in the virtual world that they lose track of the real world
The virtual world rarely incorporates the real world and its utilities, further enforcing a separation of virtual and real worlds.
Goals are self-created and revolve around "in-game" needs as opposed to real-world needs, and addicts have difficulty putting "in-game" goals into the proper context in their every day life

These issues are going to present a huge problem for people that want to see immersive VR become part of the corporate world because the corporate world will never support immersive VR with the kinds of risks associated with the statements above. The only avenue that offers a solution is a higher level of integration between the real world and VR. This step requires a great deal of additional investment in technology development beyond what exists today. To seamlessly integrate all of the information on your desktop computer with the virtual environment and to create a work environment that mimicks your real one for the purposes of collaborating across great distances is where you can start to draw the eye of the corporation.

This idea, while tantalizing for the corporation, will be wholly rejected by large portions of the current VR population that use their immersion to escape the realities of their physical existence. Remember that they are the ones investing the most in the platforms right now. That is starting to change with corporations like IBM and Sun beginning their investments in second life, but we will need to see much more corporate involvement if we are to see these emerging technologies one day become useful to the every day business.

So, thank you SL addicts. Thank you for paving the way. Please pardon the dust.

The Politics of VoIP in Developing Nations

The Politics of VoIP in Developing Nations

Recently I had an opportunity to meet with a native of Malawi. The meeting came about due to a group of visiting “ambassadors” from Africa. One of the participants was a gentleman by the name of Frank Mvalo. Per his bio:

Frank Mvalo from Malawiworks in the private sector in management and IT systems as a management consultant. During the exchange, Franks wants to learn more on strategic management and business planning, monitoring tools for the field of development, and the management of IT development projects. Frank speaks 3 languages and is married with one child. (http://www.rotary7120.org/GSETeams.cfm)

He requested a series of meetings with folks while in the US that are in the IT and Telecommunications field. The visit was organized by the Group Study Exchange (GSE) program of the Rotary Foundation. While I am not a Rotarian, I know a number of people that are. They reached out to me, and earlier this week I sat down with Frank for lunch to discuss telecommunications technologies like VoIP, and it’s potential applicability in developing nations like Malawi. The conversation quickly moved away from the technology to regulations. I learned in areas of the world where the impacts of technological advances could have the greatest impact, prohibitive regulations by corrupt governments in these developing nations prove to be the biggest stumbling block.

Later that evening, as a result of this eye-opening discussion, I decided to learn more. I performed a simple google search with the key-words “voip in third world countries” – and of the 1million plus hits, result number 1 and 3 are titled:

1) » Third World VoIP blocking has the stench of corruption 2) Techdirt: Put Down The VoIP Phone, And Come Out With Your Hands Up

From the first article:

“Namibia is the latest nation to go absolutely convulsive over the prospect of some of its citizens bypassing the local phone monopoly by selling and using VoIP. Five people have been busted.”

At a time when the digital divide widens between the haves and have nots, it’s sad to see that technical innovation is stifled at times when bridge building across the divide needs to take place. Should you read more, you will see that it’s not just policies of the third world nations, but also restrictions of financial backers. Frankly, the whole thing reeks of corruption.
