Registration open for CGL 3.2

Mar 2, 2006 — by LinuxDevices Staff — from the LinuxDevices Archive — 1 views

[Updated Mar. 3] — The first “registerable” release of the Carrier Grade Linux (CGL) 3 specification has been made. Linux distributions can now be registered as compliant with CGL 3.2, which includes a variety of changes based on feedback from specification users, according to the OSDL (Open Source Development Labs), the member-funded industry group that maintains the specification.

Compliance with the CGL specification is done by Linux vendors and distributors directly, rather than by a certification body. The process is described in this whitepaper.

The CGL v3.2 spec includes an 18-page overview document, along with seven PDF documents defining requirements for:

  • Availability — Applies to the kernel, core libraries, and essential tools, with regard to single-system availability
  • Serviceability — Defines tools and methods to manage, install, maintain, upgrade, and monitor
  • Performance — Unique performance requirements of carrier-grade applications
  • Clustering — Aimed at supporting clustered applications in a carrier-grade environment, as an effective way to achieve highly available services
  • Standards — A reference for standards such as POSIX, IETF, and DMTF referred to in the CGL 3.2 functional requirements
  • Hardware — Identifies important hardware building blocks, and the open source software needed to support it, as the industry migrates from proprietary platforms to COTS building blocks
  • Security — Objectives and requirements aimed at analyzing and mitigating threats, and improving resiliency
