网络虚拟化环境下可靠性问题研究综述

Improving Reliability of Virtual Network:A Survey

虚拟网络的可靠性随着虚拟化技术的广泛应用成为一个广受关注的焦点问题。虚拟化环境下复杂的故障机理和拓扑结构使得传统的网络可靠性优化方法很难适用于虚拟网络。基于对网络可靠性问题相关研究现状的调研,分析现有的研究成果及主要技术的优缺点,提出进一步研究的方向,为网络可靠性问题的研究提供借鉴。

The reliability of virtual network has become a research focus with the wide application of virtualization technology.But because of the complex fault mechanism and topology structure in virtualization environment,it's difficult to apply the traditional network reliability optimization methods directly to the virtual network.Related research work of virtual networks(VN) reliability are surveyed and discussed.Besides,both of the advantages and disadvantages in the major technologies of related research work are analyzed.The possible future research directions are also discussed as references for virtual networks reliability research.
