In this paper, we propose a fast restoration scheme against a link or node failure as a part of fault management of ATM network. Proposed scheme operates on VP-based ATM network performing connection establishment and routing functions based on virtual path concept. Propesed scheme is a distributed algorithm performed concurrently by network nodes neighboring failed node or link. When a node or link fails, restroation is performed according to the pre-assigned local, regional, end-to-end restoration scheme. When failure occurs, loop is expanded and this expanded loop is used for the restoration of the failed connection. We defin the requiere VP loop architecture, restoration messages and restoration procedures. Proposed algorithm is simulated and compared with general flooding restoration scheme. Simulated Results show that the proposed loop-expanding scheme can achieve fast restoration goal with lower burden to network. |
