Fault Tolerant Virtual Path Layout: Optimization Models

Broadband integrated services digital networks (B-ISDN) are designed to support a wide variety of service classes including, but not limited to, voice, data and video. These classes are different in their required bandwidth, traffic speed variation and delay tolerance. Several network architectures have been proposed, or are under development, to support B-ISDN. Probably the most prominent is the Asynchronous Transfer Mode (ATM).
