Abstract
The survivable design is a key issue in reliable WDM optical networks to assure the service guarantee to customers. In this paper we propose a novel heuristic dynamic Sub-Path Protection with Hop Constraint routing algorithm (SPP-HC) to provide a more flexible way to compute the sub-paths and the backup paths. Compared with the conventional equal-length sub-path protection metrics, SPP-HC can further improve the resource utilization ratio and reduce the blocking probability. We evaluate the effectiveness of the SPP-HC and the results are found to be promising.
