CGL is Real and Building Momentum...

As for beyond 3.1, the priorities of the CGL working group as identified based on the market input and the feedback received from participating companies in the CGL initiative are: Real-time capabilities, testing CGL workloads, device driver hardening and availability, Linux performance and scalability, in addition to further enhancement to Security and Manageability (see Figure 9).

CGL Registration Process

The registration disclosure is a self-registration process. Carrier Grade Linux Registration is the full disclosure of all the priority 1 requirements in the Carrier Grade Linux Requirements Definition. Disclosure for each priority 1 requirement indicates whether or not the requirement has been implemented. For each met requirement, then the document defines the data needed for registration disclosure. Linux distribution vendors provide the disclosure information on their web site and on the OSDL site and this public disclosure information is owned and maintained by each Linux distribution vendor. If a Linux distributor vendor did not implement a certain Priority 1 requirement(s), the vendor must disclose the reason for its absence. Linux distribution vendors that have registered with full public disclosure of all priority 1 requirements may describe their product as OSDL CGL Registered.

CGL Distributions

Currently, five Linux distributors provide CGL 2.0 registered distributions (see Figure 10). OSDL maintains a web site that lists CGL registered distributions and links to their disclosure documents: http://www.osdl.org/lab_activities/carrier_grade_linux/registration.html


Providers of CGL-Based Platforms and Products

Platform providers also use CGL registered distributions on their platforms. Those platforms end up being offered to NEPs and Carriers and are deployed on carrier networks.

Figure 11 illustrates the companies that have announced the use of either CGL based platforms in their offerings or use of their own Linux distributions based on CGL. The list is quite interesting from a geographical perspective, as CGL-based products and platforms are coming from North America, Europe and Asia.
