Inter connection network in a data center is the need of the hour as the communication backbone which caters the demands to accommodate a large number of servers with minimum possible end-to-end delay. The traditional Fat tree based topologies play a pivotal role for data center network (DCN) albeit in a low scale, on the other hand the upcoming electrical-cum-optical hybrid architecture demands huge power consumption and exhibit significant end-to-end delay. The present work depicts a proposal of highly scalable novel hybrid architecture employing optically switched WDM LANs (based on ShuffleNet topology) over electrical Fat trees with the use of substantial number of optical devices, the proposed DCN architecture is shown to offer reasonable reduction of end-to-end delay to 12.29 µs for mouse traffic and 10.01 ms for elephant traffic as compared to Optical Switching Architecture (OSA), which has significant 23 ms of delay for any traffic condition.

一种新颖的混合数据中心架构,在电子胖树上采用光交换WDM LAN
数据中心中的互连网络需要一个小时作为通信主干网,它可以以最小的端到端延迟满足容纳大量服务器的需求。传统的基于胖树的拓扑结构虽然规模很小,但对数据中心网络(DCN)却起着举足轻重的作用;另一方面,即将到来的电-光混合架构要求巨大的功耗,并表现出显着的端到端延迟。本工作描述了一种具有高度可扩展性的新型混合体系结构的提议,该提议在电气胖树上使用光交换WDM LAN(基于ShuffleNet拓扑结构),并使用了大量的光学设备,所提出的DCN体系结构可合理减少端鼠标流量和10的最大延迟为12.29 µs。
