| Abstract(in English) | In an optical network which accommodates huge amount of traffic, a single fiber failure influences many optical paths on it. Fast recover from a fiber failure is strongly required. The shared mesh protection that enables multiple protecting paths to share optical resource is required to reduce optical resource. We have proposed the fast fault recovery method to resolve the above issues. In our proposed recovery method, we first calculate routes of protecting paths, which share optical resource, before a failure occurs. And then when a failure occurs, a node that detects failure broadcasts fault notification message and nodes receiving the messages activate the protecting path. In this paper we propose the Time-Constrainted Recovery Path (TCRP) computation algorithm for pre-planning protecting paths. The TCRP algorithm searches a protecting path to provide fast recovery in the required recovery time and to reduce optical resource for recovery by sharing optical resource. Furthermore, we confirm the effective of the TCRP algorithm using simulation. |
