This paper proposes a backup path multiplexing scheme for survivable generalized multiprotocol label switching (GMPLS) networks. The shared risk link group (SRLG)-disjoint label switched paths (LSPs) share common backup resources as many as possible to achieve higher efficiency. Based on the problem formulation, the analysis on the expected recovery failure probability, the expected recovery time, and the expected signal loss reveals the upper bound of the backup path length. The simulation results demonstrate that the proposed scheme provides higher multiplexing gain.
