Virtual Path Management for Survivable ATM Networks.

Abstract

Fast restoration from a network failure has been recognized as a key ingredient in realizing survivable networks in emerging high-speed ATM environments. Self-healing techniques have been proposed to provide service continuity to end users by autonomously switching affected virtual paths to alternate routes. However, their success greatly depends on how traffic is distributed and spare capacity is dimensioned over the network when a failure occurs. Therefore, a fast restoration mechanism alone is not enough to achieve a high level of survivability. This project aims at defining an integrated framework for survivable ATM network management ranging from network design and virtual path management to fast restoration protocol. The focus is placed on two aspects essential to promoting restoration capability: the survivable virtual path routing (SVPR) and the survivable capacity and flow assignment (SCFA).
