Towards Carrier Grade Linux Platforms
Ibrahim Haddad, Ericsson Research
Traditionally, communications and data service networks were built on proprietary platforms that had to meet very
specific availability, reliability, performance, and service response time requirements. Today, communications service
providers are challenged to meet their needs cost-effectively for new architectures, new services, and increased
bandwidth, with highly available, scalable, secure, and reliable systems that have predictable performance and that
are easy to maintain and upgrade. This paper presents the technological trend of migrating from proprietary to open
platforms based on software and hardware building blocks. The paper focuses on the ongoing work by the Carrier
Grade Linux (CGL) working group at the Open Source Development Labs, examines the CGL architecture, the requirements
from the latest specification release, and presents some of the needed kernel features that are not currently
supported on Linux.
