跨数据中心大二层组网技术探讨与分析

Discussion and analysis of great network technology on the second floor across the data center

跨云计算数据中心组网要求具有高度灵活和弹性的网络架构,业务负载不论是物理机还是虚拟机,都可以在数据中心之间的任意资源上部署,为了实现以上目标,跨数据中心必须部署与传统二层网络技术不同的大二层网络技术。首先分析了传统二层网络技术的局限性,提出了数据中心对组网的需求,并对大二层技术和传统二层技术做了对比分析,然后对大二层网络技术的实现原理和适用场景进行了系统全面的介绍,最后结合运营商跨数据中心组网的项目实施案例进行探讨和分析,对新型云计算数据中心的网络规划有较好的借鉴和指导意义。

Across a cloud computing data center networking requirements are highly flexible and elastic network architecture, service load, whether physical machine or virtual machine can be deployed on any resources between data centers, in order to achieve the above goals, across data centers must deploy different from traditional network technology on the second floor of big network technology on the second floor. The limitation of the network technology on the second floor was analyzed, the demand for network was put forward, the great second floor technology and traditional second floor technology was analyzed comparatively, and then the principle and suitable scene of the great network technology on the second floor was introduced comprechensively, finally combining operators across the data center network project implementation case carries on the discussion and analysis, the research for new cloud computing data center network planning has better reference and guiding significance.
