云计算中虚拟网络服务的性能测量及运营实践

Performance analysis and operation practice of virtual network service in cloud computing

在云计算中,虚拟网络服务是核心的服务之一,用户可以在云环境中创建属于自己的虚拟网络部件,而不用考虑底层的物理网络环境.OpenStack作为目前最流行的开源云计算平台,可以通过不同的方法和技术来实现虚拟网络服务.本文针对当前的OpenStack版本,对其虚拟网络服务不同的实现方法和技术进行了详细的分析与性能测量,并介绍了上海交通大学云计算平台的运营实践现状,为高校建设云计算虚拟网络服务提供了参考.

Virtual network service is one of the key services in cloud computing,where user can create his own virtual network component without considering the physical network.As the most popular open source cloud computing platform,OpenStack has many different ways to provide virtual network service.In this paper,we analyze the current version of OpenStack,measure and characterize among different implementation ways in virtual network service.In addition,we introduce the current situation of the cloud computing platform in Shanghai Jiao Tong University.The results of the paper will provide a useful reference for the deployment of virtual network services in universities.
