一种云数据中心虚拟交换的解决方案

A solution of virtual machine communication exchange in cloud computing data center

本设计是一种替代虚拟交换机的虚拟交换方案,旨在与弥补虚拟交换机在虚拟机通信安全方面设计上的不足。其运用VEPA交换技术,通过反射数据帧,修改了生成树协议、重用Q-in-Q等技术有效的实现了监控虚拟机通信,同时降低了高度虚拟化部署的复杂性,有效的保证了云数据中心资源的最优使用率。

Considering the insufficiency in the communication safety of a virtual switch, a virtual exchange program for an alternative virtual switch is proposed. Based on the VEPA exchange technology, the spanning tree protocol is modified according to the reflection data frames, and when Q-in-Q technology is reused, the virtual machine communication can be well monitored, the complexity of highly virtualized deployment can be reduced, thus, the resources of cloud computing data center can be ensured in an optimal utilization rate.
