MontaVista Software announced that MontaVista Linux Carrier Grade Edition (CGE) 6.0 has been registered as compliant to the Linux Foundation's Carrier Grade Linux (CGL) 5.0 specification. MontaVista appears to be the first Linux distro to have registered for CGL 5.0, which was announced at the Linux Foundation Collaboration Summit last week, offering advancements in everything from streaming media to security.

At the start of the Collaboration Summit last week, the Linux Foundation (LF) announced the long-awaited Carrier Grade Linux (CGL) 5.0 for high-end networking, telecom, and industrial applications. The new spec features new streaming media, security, diagnostics, debugging, tuning, and High Availability (HA) file system support.

Now, MontaVista's Carrier Grade Edition (CGE) 6.0 is the first Linux distro to achieve registration for the spec's requirements, according to the Cavium Networks-owned company. The registration has not yet appeared on the LF's CGL registration page, but MontaVista has posted registration documents on its own site.

MontaVista had announced preliminary support for the spec when it released CGE 6.0 last October. Rival Wind River Linux 4.0, which shipped around the same time, was also said to offer preemptive support for the standard.

CGL 4.0 was released in Feb. 2007, but it wasn't until a year later that Wind River announced it was the first commercial embedded Linux distribution vendor to meet CGL 4.0 requirements. Performance Technologies (NexusWare) and MontaVista registered soon thereafter, and since then Novell has joined the list with SUSE Enterprise Server 11.

Among other enhancements, MontaVista Linux CGE 6.0 introduced a multicore resource management scheme for virtualization, and added support for Linux Containers, KVM, and EMVisor virtualization schemes. The release also upgraded its OpenSAF HA support and power management features.

In conjunction with the CGL announcement, the LF launched a new High Availability (HA) Working Group with a charter to define the open source HA software stack for mission-critical workloads running on Linux. The long list of participating HA groups did not include OpenSAF, however.

Stated Jim Zemlin, executive director of the Linux Foundation, "As a key contributor to the CGL 5.0 specification, MontaVista has shown its strong commitment to the Linux community. We are glad to accept MontaVista's CGL registration of compliance."
