云化数据中心网络的新需求及解决方案

Requirements and Solution for Network of Cloud Data Center

云计算技术实现了数据中心内部IT资源的虚拟化管理,用户可以动态、按需、实时地申请IT资源。那么,底层承载网络如何应对这种新变化,为用户实时、按需地创建相互隔离的网络连接并满足特定Qo S需求的承载服务,已成为云化数据中心解决方案关注的焦点。本文分析了数据中心网络云化后的新需求,讨论了云化数据中心网络解决方案及其关键技术,最后就如何选择云化数据中心网络解决方案给出了建议。

Due to realize the virtualization management on IT resources in cloud data center, users can dynamically, on- demand and real-time apply IT resources. How does the underlay physical network deal with the new changes to provide the carrier services for users by creating isolated network connection and meeting the demands of a specific QoS？ It has became the focus of the network solutions for cloud data center. This paper first analyzes the new requirements of cloud data center. On the basis of this, network solutions and key technologies are discussed. Finally, suggestions about how to choose the network solutions for cloud data center are given.
