%X Aiming at the requirement of energy saving in optical networks, this paper studies green network solutions and proposes a green shared path protection (GSPP) algorithm on survivable protection issue in optical networks. GSPP realizes energy saving in optical networks by isolating the working paths and the backup paths with different fibers and switching the idle and backup network resources into sleep mode. Simulation results show that GSPP can improve the network power efficiency with respect to the traditional shared path protection (SPP) algorithm, and achieve better tradeoff between total network power consumption and blocking probability performance.
