IPC: H04Q3/52
Filed: 2000-12-30
Abstract: PURPOSE: A dynamic recovering method of an optical link damaged in an optical network is provided to shorten an optical path recovering time to the maximum by previously transmitting information required for recovering during a normal operation and simultaneously transmitting only an identifier for the failure to each optical switch in a multi-cast or a broadcast method when there occurs the failure in an optical link. CONSTITUTION: An optical path set-up server transmits a suitable optical switch control command to every optical switch participating in construction of a path in order to set up a main path between two routers(S401). The optical path set-up server transmits a suitable optical switch preparation control command to every related optical switch participating in the path construction in order to set up a back-up path for the main path(S402). Upon receiving the optical switch preparation control command, an optical switching controller interprets an optical switch preparation control command and updates a mapping table of an optical link cut identifier and a connection operation of an optical input terminal and an optical output terminal for recovering related to the optical link cut identifier(S403). Each optical switch continuously checks whether there is an error on a link(S404) to confirm whether the link has been cut(S405). If there is an error on the link, the optical switch informs the optical path set-up server of an identifier of the link in question(S406). The optical path set-up server determines the type of the optical path passing the link in question and informs an optical switch to be participated in the path recovering of the failure identifier(S407). The optical switching controller of the optical switch which has received the failure identifier searches a failure identifier value from the mapping table and connects a required optical input terminal and output terminal for recovering(S408).
