LinuxPlanet: Carrier Grade Linux: Linux in Telecom

“Traditionally, communications and data service networks were
built on proprietary platforms that had to meet very specific
requirements in areas such as availability, reliability,
performance, and service response time. Those proprietary systems
were composed of highly-purposed hardware, operating system,
middleware, and often included proprietary technologies and
interfaces. Such proprietary approaches to system architecture
fostered vendor lock-in, very served to limit design flexibility
and freedom, and produced platforms that were and are very
expensive to maintain and expand.

“Today, those same service providers and carriers are challenged
to drive down costs while still maintaining carrier class
characteristics for platforms to provide service and mission
critical applications in an all-IP environment. They are in a
position today where they must move away from specialized
proprietary architectures, and towards commercial-off-the-shelf
(COTS) approaches and building practices for several
reasons…”
