摘　　要：网络虚拟化是电力通信网转型的关键技术,在保障业务QoS和提高资源利用率方面具有较大优势。但是,网络虚拟化环境下,多域服务故障诊断过程中面临着故障的域间传播信息量大和底层网络信息缺乏等问题。为解决此问题,提出了一种网络虚拟化环境下多域协作的故障诊断算法,建立了多域范围内的故障传播模型,有效隐藏了各自治域的私有信息,减少了域间传播的诊断信息量。通过仿真实验,证明了该算法可提高故障诊断的效率和准确度。Network virtualization was the key technology in the transformation of power communication network,which have great advantages in ensuring QoS and improving resource utilization.However,in the network virtualization environment,the problems of multi-domain service fault diagnosis were faced with the problem of large amount of information disseminated between the domains and the lack of information of the underlying network.In order to solve this problem,presents a diagnosis algorithm of multi-domain collaboration service failures in network virtualization environment,a multi-domain failure propagation model was established to effectively hide the private information of each autonomous domain,the information amount of interlayer communication was reduced.Simulation results show that the proposed algorithm improves the efficiency and accuracy of fault diagnosis.
