基于OpenStack云平台Neutron关键技术研究

Research on the Key Technology of Neutron Based on OpenStack Cloud Platform

云计算的网络服务承载着整个云计算平台的网络构建,因此网络模块都作为云平台主要模块之一,Open Stack中的Neutron模块作为网络管理系统,主要实现多租户情况下的网络隔离,使每个租户的网络环境独立,可以根据自己的需求部署网络环境。本文将分析Neutron模块的工作原理,利用虚拟化模拟Neutron的网络管理,运用虚拟化技术结合Libvirt与Open v Switch等软件,模拟实现类似云主机之间的通信。

Cloud computing network service carrying the cloud computing platform of network construction,so network module are as one of the main modules of the cloud platform,neutron of openstack as the network management system,mainly to achieve multi tenant network isolation,enable each tenant＇s network environment independent,can according to their own needs network deployment environment. This paper will analyze the working principle of the neutron module,the virtual simulation of neutron network management,using virtualization technology combined with libvirt open vswitch software,the simulation of the realization of communication between the cloud instance.
