Abstract :
A QoS restoration scheme for VP-based ATM networks is proposed and its related characteristics are evaluated. The proposed scheme is a state-independent restoration scheme using a disjoint path group. A VP assignment and capacity planning problem using a disjoint path group are formulated. When a failure occurs, failed working VP are switched to protection paths with the same QoS level using a simple and fast restoration algorithm. The simulated restoration characteristics of the proposed algorithm are presented. A scheme of excess capacity assignment to a protection path for dynamic traffic demands is also presented and analyzed
