摘要
根据虚拟网络在数据中心(Data Centers)网络的发展和研究现状,提出了一种基于工业电信网络圆柱型结构的数据中心网络架构。深入阐述了数据中心虚拟网络的结构、网络特性、路由策略以及构建成本等,着重分析了静态路由策略以及基于容错机制的路由算法设计与实现。利用常用TCP/IP协议构建网络内部传输模型,测试数据中心网络的传输性能、路由查询速率以及静态路由策略工作效率并进行分析,同时仿真测试了网络的负载平衡及其容错性。
Data centers are becoming increasingly important infrastructures for many essential applications such as data intensive computing and large-scale network services. According to the previous researches, this paper presented a highly scalable cylinder data center intercormection architecture, with a simple yet efficient routing scheme that maintains short path length in servers communications. It proposed fault tolerant and traffic-aware routing schemes to ensure balanced load. Experiments were used to test the transmission and routing performance of the design. Also, fault tolerance and load balance were evaluated.
