基于Open vSwitch的虚拟网络访问控制研究

摘要

虚拟化技术使得在一台物理机上可以同时运行多台虚拟机，提高了资源利用率，成为了云计算技术得以发展的基础。然而虚拟化技术也带来一些新的安全问题，并且由于虚拟化自身的特点，传统的安全手段并不足以解决这些问题。重点对虚拟网络的安全特性进行分析，并探讨利用虚拟交换机Open vSwitch对虚拟网络进行访问控制的方法。%Virtualisation technology allows multiple virtual machines to run simultaneously on a single physical machine,which improves the resource utilisation,and becomes the basis of cloud computing technology to develop.However,the virtualisation technology has also brought a number of new security issues,and due to the characteristics of virtualisation its own,traditional security means are not sufficient to solve these issues.In this paper,we focus on the analysis of virtual network security features,and explore the use of Open vSwitch to imple-ment virtual network access control.
