摘要
This paper proposes a new survivable algorithm named Sub-path Protection based on Auxiliary Virtual Topology (SPAVT) to tolerate the single-link failure in WDM optical networks. According to the protection-switching time constraint, SPAVT constructs the virtual topology. Then, it only needs to run one time of routing algorithm to find the feasible virtual route in virtual topology. Simulation results show that SPAVT has smaller blocking probability and lower time complexity than conventional algorithms.
