SPARE LINKS OPTIMIZATION IN A DISTRIBUTED RESTORATION SCHEME

摘要

To estimate an optimal amount of spare capacity for a network so that efficient distributed restoration of the network can take place in the event of network failure, parameter assumptions (20) and network design guidelines (13) are provided to a network modeling tool (2) to generate a desirable amount of spare links for the network (6). The spare links are allocated to the different nodes of the network (8). A failure is reported to the controller of the system, and the parameter assumptions and network (12, 14) design guidelines (13) are updated and fed back to the network modelling tool for further refining. Simulated failure and subsequent restoration of the network are provided to an exerciser (14) periodically. Results from the exerciser (14) further enhance the operations of the network modeling tool (2) to provide an optimal amount of spare capacity for the telecommunications network.
