In February 2005, the Open Source Development Lab (OSDL) released the latest version of the Carrier Grade Linux (CGL) Requirements Definition ? version 3.0. OSDL CGL builds on the strong adoption of the 1.1 and 2.0 releases, which now form the basis for half a dozen off-the-shelf Linux platform products and dozens of deployed systems from Telecommunication Equipment Manufacturers (TEMs) and Networking Equipment Providers (NEPs).

This article by Bill Weinberg of the OSDL provides insight into current Carrier Grade Linux adoption trends, and introduces readers to key innovations in Carrier Grade Linux 3.0. It also provides useful guidance to designers presently evaluating CGL implementations.
