摘要:

互联网产业的发展和云计算的兴起催生了跨数据中心互联的需求,而软件定义网络技术为解决数据中心互联的网络瓶颈提供了重要途径。首先介绍了几种常用的数据中心互联技术,分析了SDN的技术优势,然后提出了一种基于SDN的运营商数据中心互联承载技术方案,并阐述其实现思路。该方案可实现DC间的网络虚拟化,能够提供用户业务定制、网络自动开通、任意虚拟机间的策略隔离、流量调度、用户就近访问、DC间的容灾备份等业务功能。

Abstract:

The development of the internet industry and the rise of cloud computing have created requirements on interconnectivity across data center,and software defined network technology provides important means to solve the network bottleneck problem of data center interconnectivity.Firstly,several commonly used interconnectivity technologies across data center were introduced,and advantages of SDN technology were analyzed.Then,the operator solution of data center interconnectivity bearing technologies based on SDN was put forward,and implementation ideas of this solution were explained.It is a solution which can realize network virtualization across data center,and provide kinds of business functions,such as service customization of user,automatic accessing of network,isolation strategy between different virtual machine,traffic scheduling,the nearest access of user,disaster recovery and backup across data center.

Key words: data center interconnectivity, cloud data center, network virtualization, SDN
