DPClos:基于3级Clos结构的集装箱数据中心网络设计

DPClos:Design of network architecture for container data center based on 3-stage Clos structure

集装箱数据中心因其部署便捷在应急数据处理中发挥着基础性作用.为满足集装箱数据中心对网络带宽和容错性的需要,提出了一种基于3级Clos结构的集装箱数据中心网络,记为DPClos.DPClos能够充分利用Clos结构和双端口服务器的特点,为集装箱数据中心提供2倍网络带宽容量.DPClos网络的平均路径长度小于4,且不同层次链路之间负载均衡.双层网络结构赋予DPClos良好的容错性能,当20%设备故障时数据流的成功到达率仍超过85%.理论分析和实验表明,DPClos结构能够满足集装箱数据中心对网络性能的需求.

Owing to the convenience of deployment, container data center plays an essential role in emergency application of harsh environments. To satisfy the requirements of high network bandwidth and high fault tolerance, a novel container data center network based on the 3-stage Clos structure, DPClos is proposed. DPClos architecture takes advantage of Clos structure and the dual-port servers, which can provide double capacity of network bandwidth. The average path length is less than 4 and traffic load is balanced among links of different levels in DPClos. Bilayer structures benefit such fault tolerance of DPClos as follows： the flow success rate is more than 85% with a fraction of 20% equipments failure. Theoretical analyses and experimental results show that DPClos can meet the requirements of performance in container data center network.
