L+1容错恢复策略在复杂军事网络中的应用仿真

以标准3×3网格为基础网络,介绍了L+1容错恢复策略的概念和恢复原理,以海上舰艇编队作战系统网络为研究对象,使用Matlab-Simulink仿真工具,通过对阻塞概率、平均路径长度、路径重新分配概率和有效利用率4个指标的仿真,对比了该网络在无策略、备份多路和L+1容错恢复3种策略下网络的恢复程度,验证了L+1容错恢复策略的有效性和可行性。

Simulation for applying L+1 fault tolerance recovery strategy to complex military networks

With a standard 3×3 as the basic network,the concept and recovery principle of the L+1 fault tolerance strategy were introduced,and the navy fleet combat system networks was used as an object of research object.The Matlab-Simulink was adopted to emulate the 4 indexes: blocking probability,average path length,probability of reassignment and effective utilization.And then the reco-very degree of the network was contrasted under 3 strategies: no strategy,backup multiplexing and L+1 fault tolerance strategy.As a result,the L+1 fault tolerance strategy was proved to be feasible and effective.
