SuSE Linux announced a carrier grade Linux (CGL) edition of its server-oriented Linux operating system. SuSE's new CGL edition was developed in conjunction with HP, IBM, and Intel, and initially supports Intel-based hardware platforms, the company said.

According to SuSE, its CGL OS incorporates technologies defined by the OSDL's Carrier Grade Linux Working Group, and enables developing and deploying "products and services on standards-based, modular communications platforms" featuring enhanced "performance, reliability, and availability."

Key features of SuSE CGL, relative to the requirements of communications applications, are said to include . . .

Improved high availability features for error detection and rapid failover for the operating system, applications, Ethernet and disk.
Greatly improved serviceability enhancements enabling faster problem determination -- system memory dumping, system probes and tracing.
Improved system scalability/performance.
IPv6 RFCs compliance -- support for IPv6 for delivering next-generation network support, including a wider address space, better auto detection and auto configuration of networks, hosts and services and more efficient routing and broadcasting.
MIPv6 RFCs compliance -- support for mobile IPv6, which specifies the operation of mobile computers and devices using IPv6 -- allowing each mobile node to be identified by its home address regardless of its current point of attachment.
Soft real-time performance -- configure a scheduler to provide soft real-time support with low latency.
Low latency -- reduces the latency of the kernel reaction to real time or interactive events for low-priority processes even if the kernel works under heavy load.
RAID 0 Support -- striping support to enhance performance for request-rate-intensive or transfer-rate-intensive environments.
Application pre-loading -- supports full loading and pinning of the pages of an application before execution -- ensuring no slowdown can happen as with demand-pages execution. Needed in diskless environments to reduce network traffic and bursts execution speed.
Concurrent timers -- Supports large number and better scalability of many concurrent timers.
