Have you tried to have a meaningful long-distance, cell-phone-to-cell-phone conversation recently? If not, go try it.

Convergence: Are We On the Right Path?

Huawei Technologies — Wed, 20 Oct 2010 14:20:00 GMT

Is a “Digital Pearl Harbor" really pending in the networking industry?

Convergence – What’s With IPTV?

Huawei Technologies — Wed, 04 Aug 2010 21:58:00 GMT

The reality is this: One particular screen will not displace the others and that all three screens (TV, PC and cell phone) will coexist for the foreseeable future.

The FCC Can Relax

Huawei Technologies — Fri, 23 Apr 2010 14:42:00 GMT

The inexorable convergence of IP-based communications means that the FCC doesn't need to initiate any immediate action to achieve its goals regarding Net neutrality.

The Politics of Displacement

Huawei Technologies — Wed, 13 Jan 2010 16:05:13 GMT

More than a year after the start of this blog focused on telecommunications technology convergence, the telecom industry appears to be still struggling in its attempts to deploy an all-encompassing solution that will carry it throughout this new

Telecom Convergence and Moore’s Law

Huawei Technologies — Fri, 23 Oct 2009 19:02:38 GMT

It will come as no surprise to PC users that processing performance has come to a plateau for a few years now. Furthermore, it should also not come as a surprise, as least to those not in denial, that a similar geographical feature has developed in

The Video Triangles

Huawei Technologies — Wed, 09 Sep 2009 12:00:19 GMT

Video-based electronic content was identified in the last instance of this blog as the primary driver behind bandwidth considerations in a convergent network. However, bandwidth is only one of the many dimensions of the electronic video transport

Bandwidth Crunch Begins

Huawei Technologies — Mon, 20 Jul 2009 23:16:29 GMT

Previous instances of this blog discussed the various services that will have to be addressed by the ongoing telecommunication convergence. In particular, the bandwidth needs of tele-entertainment services, HD tele-conferencing and cloud computing,

Perfect Convergence Technology Remains Elusive

Huawei Technologies — Wed, 17 Jun 2009 15:18:54 GMT

Despite their advantages, at least for some services, thorny issues, primarily related to hard-QoS, reliability and network synchronization still hover over both Ethernet and yet another network-convergence candidate: Internet Protocol over

DPI … Anyone?

Huawei Technologies — Fri, 15 May 2009 17:45:09 GMT

Deep Packet Inspection (DPI) usually defines a set of technologies that reach beyond the header of a packet to also examine the attached payload. Among other reasons, the need for this networking practice has often been justified as to help ensure

How Much QoS Do We Need?

Huawei Technologies — Tue, 21 Apr 2009 14:54:19 GMT

In the previous instance of this blog, we discussed qualitatively the services to be addressed by potential convergent network technologies. However, to put the upcoming QoS challenges in a proper perspective, and also to allow characterization of

Rethinking Transport for the Tele-Entertainment Age

Huawei Technologies — Tue, 31 Mar 2009 18:36:37 GMT

The two previous instances of this blog elaborated the causes behind the failure of ATM to become the convergent technology. Before we look at the candidate technologies lined-up in the starting blocks, it may be worthwhile to first examine the

ATM – The Reality Behind the Cloud

Huawei Technologies — Wed, 11 Feb 2009 15:05:46 GMT

In the previous installment of this blog, the business reasons that caused ATM not to be widely deployed in the 1990s to replace our aging Class 5 switches were discussed.Along with these primarily economic considerations, a number of technological

No Business Case for a Class 5 ATM Switch

Huawei Technologies — Tue, 20 Jan 2009 21:52:01 GMT

The previous installment of this blog described how a ‘divergence’ into separate voice and data networks may have been caused in the 1990s by network service providers opting to route the increasing data traffic around their Class 5

Where Did We Diverge on Convergence?

Huawei Technologies — Fri, 09 Jan 2009 14:02:53 GMT

As discussed in the first installment of this blog, reaching a common understanding as to what exactly is “convergence” can be a complicated matter. Catch phrases such as triple play and quad play appear to have become a must-have in the

Convergence: The Year Was…?

Huawei Technologies — Fri, 12 Dec 2008 16:48:25 GMT

“Those who cannot remember the past are condemned to repeat it.”One may wonder how this statement by George Santayana may apply to such a forward-looking topic such as telecommunications convergence, an area where the newest and most
