基于云服务的DCOS分层网络体系结构的研究

Research on the layered network architecture of DCOS based on cloud services

基于云服务的数据计算和存储需求的不断增长推动了大型数据中心的开发和部署。在多个数据中心运营商同时为多个业务用户(SSS)服务时,数据中心网络系统的资源合理分配问题日益突出。同时,互联网流量的快速增长和丰富的数据驱动应用程序的丰富性,提高了对巨大网络带宽的需求。针对上述需求,提出了一种基于云的可重构分层光数据中心体系结构(RHODA)。通过使用光学空间交换机和波长选择交换机(WSSS)实现集群间网络拓扑和链路容量重新配置。模拟结果表明,在平均跳距方面,RHODA比OSA、Fattree和WaveCube分别高出81%、66%和60%。

The growing demand for data computing and storage based on cloud services promotes the development and deployment of large data centers.When multiple data center operators serve multiple business users(SSS)at the same time,the problem of rational resource allocation in data center network system becomes increasingly prominent.At the same time,the rapid growth of Internet traffic and the richness of data-driven applications have increased the demand for huge network bandwidth.To meet the above requirements,a reconfigurable hierarchical optical data center architecture based on cloud(RHODA)is proposed in this paper.The inter-cluster network topology and link capacity are reconfigured by using optical space switch and wavelength selective switch(WSSS).The simulation results show that RHODA is 81%,66%and 60% higher than OSA,Fattree and WaveCube in average jump distance.
