Linux Foundation Releases New Carrier Grade Linux 4.0 Specification

New Requirements Specification Focuses on Cooperation With SCOPE Alliance and Tighter Compliance

    SAN DIEGO, Feb. 27 /PRNewswire/ -- At the Communications Ecosystem Conference today The Linux Foundation, the new organization formed last month from the merger of the Open Source Development Labs and the Free Standards Group, today announced availability of its Carrier Grade Linux 4.0 Specification. In existence since 2002 and now in its fourth version, the Carrier Grade Linux (CGL) Specification consists of over 250 individual requirements that cover seven categories of Performance, Hardware, Standards, Serviceability, Availability, Security and Clustering. The primary changes to the new CGL 4.0 Specification are alignment with the SCOPE Alliance's Carrier Grade Profile and tighter requirements around compliance.     An indication of the growing importance of the CGL Specification is the fact that the Scope Alliance, an industry association made up of the top Telecommunications Equipment Manufacturers (TEMs), has created a profile of the Carrier Grade Specification that specifies priorities for the individual requirements based on their own equipment requirements. A major part of the new CGL 4.0 specification is the alignment of the specification with the SCOPE Alliance profile. This has the benefit of helping to ensure that the Specification is meeting the needs of its primary users, the TEMs.     "SCOPE and the Linux Foundation are both committed to accelerating the deployment of carrier-grade base platforms based on open industry specifications," said Leslie Guth, SCOPE Alliance marketing co-chair and board member. "With the cooperation of OSDL prior to the merger and the Linux Foundation since, we've worked to align the CGL Specification with our released Carrier Grade profile and we look forward to benefits such as faster time to market that interoperable commercial off-the-shelf building blocks bring."     The new CGL 4.0 specification assigned priorities to the requirements with key input from the SCOPE Alliance profile to ensure that any company registering their Linux software as CGL compliant implemented all of the mandatory requirements. The CGL 4.0 categories of requirements are Mandatory, Desired and Roadmap items. Previously any Linux distribution that met even a few of the requirements could claim compliance. But the new Specification requires inclusion of all Priority 1, or Mandatory, requirements (there are 135 specific Mandatory requirements) before a distribution can claim its product is CGL compliant. Full details of the CGL 4.0 registration process will be released in the near future.     "This release of the Specification has a significant effect on the viability of the specification and ensures that when an equipment provider specifies Carrier Grade Linux there is a consistent standard for what that means. The inclusion of mandatory requirements is a major step and will have an impact in the growth and continued adoption of the CGL specification," said Glenn Seiler, Steering Committee chairperson for the Carrier Grade Workgroup.     "I'd like to congratulate the CGL for the enormous effort they've contributed to enable publishing this specification," said Jim Zemlin, executive director of The Linux Foundation. "With the publication of CGL 4.0, The Linux Foundation has re-chartered the CGL as a Linux Standard Base workgroup. We look forward to working with CGL members as well as the rest of LF members and the larger Linux community in integrating carrier-grade requirements into the LSB process."     The Linux Standard Base (LSB) delivers interoperability between applications and the Linux operating system. Currently all major distributions comply with the LSB and many major application vendors, like MySQL, RealNetworks and SAP, are certifying. The LSB offers a cost-effective way for application vendors to target multiple Linux distributions while building only one software package. For end users, the LSB and its mark of interoperability preserves choice by allowing them to select the applications and distributions they want while avoiding vendor lock-in. LSB certification of distributions results in more applications being ported to Linux and ensures that distribution vendors are compatible with those applications. In short, the LSB ensures Linux does not fragment.     The new CGL workgroup of the LSB will focus on defining the necessary interfaces and modules to enable the testing and certification of carrier grade features in Linux distributions.     The Free Standards Group and the Open Source Development Labs recently merged to create the Linux Foundation. Both organizations have been very active in defining important standards and specifications for the Linux community. The Free Standards Group's LSB is the de facto standard used for application portability on the Linux platform. The new Linux Foundation is committed to the growth and support of the Carrier Grade Specification and working with the Scope Alliance and other industry organizations to ensure that CGL becomes the de facto Linux for all communications platforms.     About The Linux Foundation     The Linux Foundation is a nonprofit consortium dedicated to fostering the growth of Linux. Founded in 2007 by the merger of the Open Source Development Labs and the Free Standards Group, it sponsors the work of Linux creator Linus Torvalds and is supported by leading Linux and open source companies and developers from around the world. The Linux Foundation promotes, protects and standardizes Linux by providing unified resources and services needed for open source to successfully compete with closed platforms.
