摘要：

根据电力业务的QoS要求,提出了基于业务特征指标的电力通信网抗毁性评估方法.该方法考虑业务传输有效性的多项指标,对业务QoS指标与重要度进行有效融合,以此为基础构建了网络抗毁性评估模型.对不同攻击方式下的电力通信网抗毁性进行了分析,结果表明,网络最优攻击和贪婪攻击下的抗毁性较差,且业务在各链路上分布得越集中,网络的抗毁性越差.以仿真结果为基础,利用动态更新链路权值实现了负载均衡,提高了网络抗毁性.

Abstract：

A invulnerability assessment method of the EPCN on the feature index of the service by QoS requirements for power service is proposed in this paper.In this method' invulnerability evaluation model for network is established based on the QoS and service importance with the consideration of multi-indexes for the effectiveness of service transmission quality.The invulnerability was analyzed in different scenarios under several types of attacks.The results show that the network invulnerability is poor under greed and optimal attacks,the more concentrated the distribution of service importance level is,the worse the vulnerability is.The simulation results show that using the load balance based on dynamic update link weights can relatively improves the network invulnerability.
