Abstract

Optical Self-Healing Ring (SHR) offers high level of resilience at low cost, since it is often geographically easy to take multiple paths and link them up into a ring with very little extra optical link length. However, the self-healing performance of optical ring networks is limited, and the limitation of self-healing ability of ring networks becomes a problem to be studied. We proposed a conception of the minimum network and three kinds of minimum networks of the Bi-link undirection multiplexing segment protection ring network are found, and through which, the network fault tolerance rate of the two practical applications of all nodes communication and key nodes communication is derived, which provides a reference for evaluating the finiteness of self-healing performance of the Bi-link network, and it is found that the network fault tolerance rate of key nodes communication is related to the ring network distribution of key nodes, and the more closely distributed the network fault tolerance performance is stronger.
