Paper Abstract

Optical layer networking and survivability are very important branches of the study of optical communication network. Recent standards proposals have focused on extending MPLS protocols to manage optical network resources. These proposals have concentrated on provisioning optical connections and offering restoration capability in mesh optical networks. Few papers, however, are concentrated on protection issues of backup path. By considering the protection of backup path, survivability of protection scheme will improve. This article presents a novel paradigm enhancing the existing pre-established protection schemes using Multi-Protocol Lambda Switching architecture and demonstrates local restoration and global restoration for backup path with examples. Finally, we discuss the advantages of this approach and present future work.
