Abstract

The article deals with the integrated design and analysis of a telecommunications network to achieve specified levels of survivability under various failure modes and conditions. The main goal of the article is: given a criterion for network survivability, develop a unified theory for network planning at different “layers” of the network, and for coordinated restoration methods after a failure. While most of the discussion relates to modern circuit-switching architectures, for completeness, asynchronous transfer mode technology is also considered
