摘　　要：面对日益庞大的网络用户需求,传统的TCP/IP体系架构早已不堪重负,暴露出服务质量难以保障、路由故障恢复效率低下、可拓展性差等弊端。为应对这些挑战,提高网络的容灾性,科学家们将覆盖网络引入网络灾后恢复研究中。覆盖网络可以在保留当前互联网结构的基础上通过合理选择连接节点构建新的逻辑网络,从而提供路由、组播、内容分发等基础性服务。首先介绍覆盖网络的发展现状和网络容灾性的含义,然后对相关文献进行整理与分类,围绕覆盖网络在灾后恢复方面的应用讨论灾难损毁故障建模方案和受损网络连接恢复策略,同时指出当前基于覆盖网络的灾后恢复研究存在的不足之处,并对未来发展方向进行展望。Faced with the increasing demand of network users,the traditional TCP/IP architecture has long been overwhelmed,exposing drawbacks such as difficulty in ensuring service quality,low efficiency in routing fault recovery,and poor scalability.In order to meet these challenges and improve network disaster tolerance,scientists have introduced overlay network into the research of network disaster recovery.The overlay network can build a new logical network by reasonably selecting connection nodes on the basis of retaining the current Internet structure,so as to provide basic services such as routing,multicast,content distribution,etc.First,the development status of overlay network and the meaning of network disaster tolerance are introduced.Then,the relevant literature is sorted out and classified.Based on the applica-tion of overlay network in disaster recovery,the disaster damage fault modeling scheme and damaged network connection recovery strategy are discussed.At the same time,it points out the shortcomings of current research on disaster recovery based on overlay network,and looks for-ward to the future development direction.
