“…And, VPG (Virtual Path Group) concept may enhance the restoration time performance. VPG is a logical bundle of one or more ATM VP network and/or subnetwork connections that share the same transmission path(s) within the protected domain [8]. Also, it would be useful that different survival architecture is used based on the demand distribution, network connectivity, and demand growing conditions [1].…”

A QoS restoration scheme for VP-based ATM network 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 disjoint path group are formulated. When a failure occurs, failed working VPs 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 protection path for dynamic traffic demands is also presented and analyzed.
