Deployment and Performance Evaluation of Virtual Network based on OpenStack

In the context of the ever-developing virtual network, OpenStack officially launches its new network componentQuantum, but the comparative performance between singlehost and multi-host deployment is yet unknown. The paper introduces detailed deployment strategies of single-host and multi-host after analyzing Quantum work mechanism and the construction polices of virtual networks. And then, we probe into the influence of various deployments on the reliability of network service, and conduct connectivity and performance tests on different deployment plans. Experiment results show that our virtual network multi-host deployment plan improves virtual network service reliability and efficiency compared with single-node node.
