为了提高通信网络中节点重要性评估的准确度和有效性,提出一种同时考虑拓扑与业务影响的评价节点重要性的双指标评估方法。在拓扑因子的确定时,应用计算节点的核度积的方法,一是可知网络的连通程度,二是可以计算出最短路径的增加的部分,从而动态调整网络。业务因子部分是应用接连失效的理论,考虑网络上负载的动态变化。该双指标方法能对令现有多种单指标方法失效的网络进行节点重要性评价,克服了现有各种方法的缺陷。实验分析表明:该方法简单有效。
In order to improve the accuracy and validity of node importance evaluation in communication networks, a dual index evaluation method is proposed to evaluate the importance of nodes considering both topology and service impact. When determining the topological factor, the method of calculating the kernel degree product of nodes is used. One is to know the connectivity degree of the network, the other is to calculate the increased part of the shortest path so as to dynamically adjust the network. The business factor part is the application of the theory of successive failures, taking into account the dynamic changes in the load on the network. The dual index method can evaluate the node importance of the networks that make the existing methods of single index invalid, thus overcoming the shortcomings of various existing methods. Experimental results show that this method is simple and effective.
