Re: Carrier Grade Linux (CGL) -- Adoption level in industry?

Hi Rajan
It is a general consensus that CGL was very successful in its charter to drive Telco requirements into Linux. 
Several leading Telco Equipment Manufacturers incorporated CGL into their wireless and fixed solutions. I would estimate most networks have some device with CGL in the network. But it is almost impossible to verify that in any kind of report. 
Linux is undeniably the leading OS in RAN today.

Thanks Glenn, your response settles most of the questions.

Maybe the last one: Are telcos using Linux? Did CGL team (or anyone else) create any summary report that tells how successful CGL effort was? I know that there're some distros that got CGL5 self-certifications but I couldn't find information whether these distros (or newer Linux kernels with other appropriate open-source packages) are deployed in Telcos.

Regards,
Rajan

Hello
I served on the CGL team during its entire lifecycle. After 5.0 we put the project into maintenance and continued to do some validations.
As someone stated earlier, nearly all functionality specified in the CGL spec is now either in the Linux kernel or other upstream projects.
CGL was originally created for Telco market in 2002 when Linux was still mainly designed for an Enterprise.
I hope that helps
