基于改进胖树结构的数据中心网络设计

The design of data center network is improved based on fat tree structure

随着云服务的广泛应用,部署云服务的数据中心网络向着大型化,多路径的结构发展。胖树运用简单的拓扑模型为数据中心提供出色的聚合带宽性能。本文提出一种基于改进胖树结构的新型数据中心网络,该网络利用边缘交换机直接连接核心交换机,并为其设计了错误避免路由算法,为数据中心网络提供简单高效的路由生成办法。通过计算得知改进型胖树结构的数据中心网络有更短的路径,同时能简单快速构建路由表。

As the widely use of cloud service, the network of the data center which deploys the cloud service is bigger and with multiple path. The fat tree, which uses simple topology, can provide a higher aggregate bandwidth. A new network architecture based on improved fat-tree is proposed, which employs the edge switch connecting the core switch directly. And the error avoidance routing algorithm is designed, which provides simple and effective routing generating method. The computing results show that, the routing path of the new network is shorter, and the routing tables is simple and fast to construct.
