电力ASON中基于SRLG完全分离P圈的链路故障保护算法
A link failure protection algorithm applying to power automatic switched optical network based on p-cycle with completely separated SRLG
摘要
Abstract
Combined with the requirements for survivability and reliability of power optical fiber communication network, a link failure protection algorithm based on p-cycle is proposed for dynamic traffic in the power automatic switched optical network under the constraints of shared-risk-link-group (SRLG). For the given network topology, an integer linear programming model is designed to off-line configure an optimal set of p-cycles with completely separated SRLG. This configuration guarantees 100% single link failure protection;meanwhile, it achieves a single SRLG failure protection. In case of dynamic traffic, the optimal routing strategy is used to find the working path and allocate the protection capacity dynamically. The simulation results show that the proposed algorithm has the capability of partial double-link failure protection, and its protection capacity is between the capacity of single link failure protection and the full double-link failure protection. Therefore, the proposed algorithm is a kind of effective mixed protection of single link and full double-link failures protection in the power automatic switched optical network.关键词
