Cable & Wireless (AS 3561) implements a strict traffic engineering network underlying its IP transit networks. This network has existed in some form or other for the last six years, and has provided C&W a high level of determinstic behavior and stability. This presentation will cover the major elements of that traffic engineering architecture, as well as some of the considerations and trade-offs made in the implimentation of the architecture.
