A New Link-Based Hamiltonian Cycle Protection in Survivable WDM Optical Networks

摘要

In this paper, we propose a new Link-Based Hamiltonian Cycle Protection (LBHCP) scheme for tolerating the single-link failure in WDM optical networks. From theoretical analysis and simulation results, we can clearly see that LBHCP has better resources utilization ratio and faster recovery time than previous path-based shared protection scheme.
