摘要:
提出了WDM光层连通可靠性的评估方法.根据网络邻接矩阵和结构参数矩阵用遍历法和不交化法计算出所有源宿点对的最小路集,通过概率求解得出各源宿点对的连通可靠度,进一步计算出网络的平均故障间隔时间、故障频率和维修频率.对类Cernet网和Mesh-Torus网进行评估仿真的结果表明,Mesh-Torus网络的连通可靠性整体水平比类Cernet网络高.基于此法对WDM光层连通可靠性评价的结果,可作为整个光网络可靠性综合评估的重要依据.
Abstract:
An evaluation method for WDM(wavelength division multiplexing)optical layer’s connectivity reliability is presented. Firstly all the minimal path sets of source-destination node pairs in the network are calculated using optimized node-traversal method and direct disjoint method according to adjacency matrix and network structure parameters matrix. Then connectivity reliability of source-destination node pairs is obtained through probability solution. Furthermore, MTBF(mean time between failures)and failure frequency as well as maintenance frequency of the network are figured out. Simulation results on Cernet and Mesh-Torus network show that connection reliability of the latter is higher than that of the former. Data results based on this method are important gist of reliability synthetical estimation for the whole optical networks.
