Abstract:In this paper, the reliability of layered area protection communication system based on SDH optical network is studied, and a series of countermeasures are proposed to solve the challenges faced by the system in complex network topology, fault recovery time delay and system resource limitation. By analyzing the research status of reliability evaluation methods, failure modes and failure recovery, and reliability optimization techniques, this paper summarizes the key problems of system resource limitation, system monitoring and management. Aiming at the system resource limitation, an optimization algorithm and dynamic resource allocation strategy are proposed to improve the reliability of the system. Aiming at system monitoring and management, this paper puts forward perfect monitoring methods and management strategies to discover and deal with faults in time to ensure the normal operation of the system. Through the experimental evaluation of the actual system, the effectiveness of the proposed countermeasure is verified.
