Carrier Grade Linux 4.0

A transformation in the telecommunications industry is underway. Fixed-line operators and wireless and Internet service providers are actively building out the next generation of Internet Protocol–enabled telecommunications services and applications:

  • Mobile video
  • Video telephony (IPTV)
  • Media file sharing/downloading
  • Multimedia Messaging Service (MMS)
  • Social networking and streaming
  • Location- and presence-based services
  • More

For network operators, delivering these new services has reached the same mission-critical level as voice. There is now an unwritten expectation for an “always-on” 100% uptime service level agreement. For equipment providers, carrier grade has become the new mandate for the next generation network (NGN). The network elements that deliver these services must provide carrier grade reliability that guarantees high service availability and uptime of 99.9999% or better. The operating system at the heart of these network elements is Carrier Grade Linux (CGL).

The Carrier Grade Linux specification was developed by the Linux Foundation, industry representatives from leading Linux companies, and the SCOPE Alliance (network equipment providers). The latest CGL specification, version 4.0, includes more than 250 specific requirements representing seven different technology focus areas: availability, clusters, serviceability, performance, standards, hardware, and security. Wind River is a key contributor to the current CGL specification and is committed to advancing future versions.

Wind River Linux complies with the CGL 4.0 specification, x86-based architectures (from Intel), as well as MIPS-based platforms (from Cavium Networks and RMI).

Wind River Linux has been integrated with many of the industry's most popular telecom boards, making it an ideal fit for the telecommunications and networking markets. It supports the emerging PICMG 3.x Advanced Telecommunications Computing Architecture (ATCA) specification and various high-availability functions and includes a standards-based interprocess communication (IPC) mechanism that connects Linux and VxWorks. Based on Linux kernel 2.6.27 and GCC 4.3, Wind River Linux includes more than 500 integrated and validated software packages, specifications for fast boot-up time, small footprint and performance optimization, and sophisticated multicore features such as virtualization and multicore offload.

Wind River Linux is the platform of choice for many of the leading industry equipment manufacturers and suppliers. Companies such as Motorola, Airvana, Itatel, Avaya, and other leading telecommunications equipment manufacturers (TEMS) and network equipment providers (NEPs) have standardized on Wind River Linux for their Carrier Grade Linux operating systems. The platform has been integrated, optimized, and tested with the leading multicore processors, commercial off-the-shelf (COTS) solutions, AdvancedTCA hardware solutions, and software middleware systems.

"Carrier Grade Linux has become a key requirement for companies not only in the network equipment market, but wherever stringent availability, scalability, and service response characteristics are mission critical requirements. Wind River Linux brings the open standard CGL to a broad range of MIPS multicore processors, one of the most exciting hardware architectures in the market today."
Jim Zemlin, executive director of the Linux Foundation, the nonprofit organization that promotes, protects and standardizes Linux, and also created the CGL specification.
