The CGL 3.2 Requirement Document was released on February 14, 2006. The CGL 3.2 will be available for registration starting February 27, 2006. The registration process of the CGL 3.2 will be published by February 27, 2006. Please send comments on any of these documents to thelf_carrier mailing list.

Carrier Grade Linux Requirements Definition Overview V3.2 (pdf)

• The CGL V3.2 requirements documents define the next generation Linux for carrier grade implementations. This document gives a summary of the documents in the V3.2 document set (Availability, Serviceability, Performance, Clustering, Standards, Hardware and Security).

Grade Linux Availability Requirements Definition V3.2 (pdf)

• Availability requirements apply to the Linux kernel, core libraries, and tools essential to a carrier-grade system. These availability requirements are related to single system availability.

Availability Development Guideline

Carrier Grade Linux Serviceability Requirements Definition V3.2 (pdf)

• Serviceability requirements define the tools and methods used by system administrators to manage, install, maintain, upgrade, and monitor a carrier grade system.

Serviceability Development Guideline

Carrier Grade Linux Performance Requirements Definition V3.2 (pdf)

• Performance requirements have a significant bearing on application performance. Carrier grade applications have some unique requirements, although they also share many needs with more general applications.

Performance Development Guideline

Carrier Grade Linux Clustering Requirements Definition V3.2 (pdf)

• Clustering requirements are aimed at supporting clustered applications in a carrier-grade environment as an effective way to achieve highly available services inside a network element.

Clustering Development Guideline An analysis of open source cluster-related projects that address CGL requirements.

Carrier Grade Linux Standards Requirements Definition V3.2 (pdf)

• Standards requirements cover the intersections of the OSDL CGL requirements with those of “recognized” standards bodies, such as POSIX, IETF, and DMTF. This document serves as a reference for the standards referred to in the CGL 3.2 functional requirements.

Standards Development Guideline

Carrier Grade Linux Hardware Requirements Definition V3.2 (pdf)

• The telecommunication industry is migrating from proprietary platforms toward a commercial off the shelf (COTS) building blocks infrastructure. Important hardware building blocks for carrier grade systems and the open source software needed to support this hardware are identified in this document.

Hardware Development Guideline

Carrier Grade Linux Security Requirements Definition V3.2 (pdf)

• The security objectives and requirements in this document are aimed at analyzing and mitigating threats and to improve resiliency to attacks on CGL systems.

Security Development Guideline

The CGL 3.1 Requirement Document was released in June 2005. It is the third major release of the CGL Requirement Document 2.0 and 1.1. Early 2005, the CGL working group has released a “Technology Release” versioned 3.0, which was just meant as a preview of the ongoing progress with the CGL requirements. Development of 3.1 defined capabilities is ongoing. The CGL 3.1 is not available for registration. Instead, you can register for CGL 3.2.

TheClustering White Papers are contributions from CGL participants. These white papers were used as the basis for discussions when the CGL working group was developing the CGL clustering model.

A use case explains the usage model of a particular requirement, in a carrier environment, as well as why it is needed in the CGL specifications.
