Loopback Interconnect Datacenter Optical Network
摘要
Abstract
[Objective]A Loopback Interconnect Datacenter Optical Network(LIDON)is proposed for switching in datacenters based on commercial devices.[Methods]The architecture is mainly composed of two switching modules,the Rack Expansion Module(REM)and the Loopback Interconnect Module(LIM).The intra-and inter-Pod switching in datacenters is accom-plished with those two modules operating collectively.By developing the new functions of diagnostic ports of a wavelength se-lective switch,LIDON boasts several features,such as high path diversity and robust tolerance.Moreover,the scalability of LIDON is guaranteed by the proposed scheme to support the flexible switching volume.[Results]The feasibility of dividing in-tra-and inter-Pod signals in LIDON was demonstrated by the filtering performance experiments on the switching components.The simulations of the task completion time for different services measure the fault tolerance of LIDON.[Conclusion]The test and simulation results show that the proposed architecture has high path diversity and strong fault tolerance.关键词
