When we started the Nortel Enterprise Blog, one of the goals was to develop a forum for ideas from the larger Nortel Enterprise Community. Now that the blog is running and achieving some level of following, I thought it was time to introduce the first guest posting.

Brad is a CISPP certified security professional and focuses on a variety of security issues from VoIP to data centers.

As I discussed in earlier blogs, both text and the act of typing are limited in their ability to convey both information and collaboration. A recent event in a totally separate field caused me to begin to think if a change is already underway.
Being somewhat of a car enthusiast, I subscribe to Road and Track. In the December 2007 issue, there is a review of the new Ford Focus. One hot feature of the new Focus is called Sync, a technology capability that enables the car to interact with Bluetooth Cell Phones and iPods through the car and using speech recognition. The reviewer waxes idyllic about using his voice to access songs on his ...

One topic that continues to intrigue me is the relationship between the demand for bandwidth created by the applications we run and the bandwidth available in the networks we use. When these are out of alignment, the system is unbalanced and can create significant operational and user issues.
This thought process led to the Edholm's Law of Bandwidth 4 years ago and thoughts on how to manage delivery of content to different networks that a device might be connected to.

I did a keynote address at the Insight 100 Fall Conference in Charlotte this week. The Insight 100 is the user group for customers deploying the Nortel CS2100 and SL-100 systems. There were over 100 customers from a wide variety of segments (finance, health care, government, education, etc.), typically with deployments from 20K plus at a single site to 200K with a centralized solution.
One interesting development that seemed to be taking place across the board is the use of a centralized model for new deployments. Much of the discussion was around the challenges of centralization and issues such as survivability and continuity.
Based on these interactions, I came to 2 conclusions:
The concept of a non-nodal VoIP system ...
