摘要
实现物理网络资源共享的虚拟光网络映射技术为新应用的发展提供了机会,为提高部署在虚拟光网络上的业务可靠性,虚拟光网络生存性问题已经引起了广泛关注。介绍了虚拟光网络生存性原理,从3个不同角度分析了虚拟光网络生存性问题,并基于此问题进一步分析了虚拟光网络的优化。最后,分析了目前研究中未重点关注的内容,为虚拟光网络生存性的研究提供了参考。
The virtual optical network mapping technology which realizes the sharing of the physical network resources, provides an opportunity for the development of new applications, in order to improve the service reliability of virtual optical network, the problem of virtual optical network survivability has attracted much attention. This paper introduces the principle of virtual optical network survivability and analyzes the problem of virtual optical network survivability from three different angles. Based on the problem of virtual optical network survivability, the optimization of virtual optical network is further analyzed. Finally, the paper ana- lyzes the content that is not focused on in the current research and provides a reference for the study of prob- lem of virtual optical network survivability.
