    【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 accomplished with those two modules operating collectively. By developing the new functions of diagnostic ports of a wavelength selective 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 intra- 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.
