Carrier Grade Linux


Since in early 2002 we’ve followed the trials and tribulations of Linux trying to get some respect in the world of telecom. It has crept in, operationally, in various devices (think data routers, ip switches, VOIP routers and handsets—Android) but has yet to be accepted as a mainstream alternative.

I’ve been working on the…

In 2002 the Linux Foundation set up a working group for Carrier Grade Linux (CGL).¬†They have been working diligently for nearly seven years and we’ve managed to follow their progress. In 2007-03 the version 4.0 specifications were released (they are grinding out Version 5.0 specs now) and have been adopted by a number of manufacturers. For a short review you can read our previous post about¬†Carrier Grade systems. It’s been six long years of CGL slogging and only recently is the market opening up with deliveries of CGL operational capability.

What’s the news?

It has to be rather disappointing to the proponents of CGL as a recent scan of the popularity of the term “Carrier Grade Linux” on the web has been slowly declining. We’re not sure why this is the case, but it could be for one or two reasons.

  1. Suppliers are using the specification in their product but not referring to it (marketing strategy?) or
  2. that in fact it is not an important point in the world of the web.

We’re not sure and cannot draw any conclusions at this point, but we love graphing things.

Turning point

The opportunity to utilize carrier grade Linux is increasingly getting airtime at senior levels of various carriers. It is an opportunity for considering significant change models, but comes with some significant challenges. If your company is considering CGL then you need to pay attention.
