title = "Multiple shared backup cycles for survivable optical mesh networks",
abstract = "This paper proposes a backup network planning method for survivable WDM mesh networks. The proposed method centers around multiple backup cycles where each network link is assigned m backup cycles and each cycle protects 1/m of the working capacity of a target link. Distributed link restoration is performed using preplanned cycles, in which both the backup paths and the spare capacity can be shared. The preconfiguration of the cycles and the spare capacity placement are derived directly from the network topology off-line, which is independent of the primary traffic status or its dynamic changes over time. The proposed method provides efficiency and simplicity to survivable network design and management, and also to runtime recovery operation. Experimental results show that the proposed method needs on average under 60% of spare capacity redundancy for single link failure while preserving the speed of cycle-based restoration.",
