摘要

【目的】

针对数据中心交换网络，文章提出了一种基于商用光交换器件的环回互连数据中心光网络（LIDON）。

【方法】

文章所提架构主要由机架扩展模块（REM）和环回互连模块（LIM）两个光交换模块组成。数据中心中的组内和组间交换通过这两个模块共同工作来实现。通过开发波长选择开关诊断端口的新功能，LIDON具有较高的路径多样性和容错性等特点。此外，文章所提方案可以保证LIDON的可扩展性，以支持交换容量的灵活扩展。

【结果】

交换器件的滤波性能实验验证了LIDON交换网络分离传输组内和组间信号的可行性。对不同业务的任务完成时间的仿真验证了该架构的容错性能。

【结论】

测试和仿真结果展示了文章所提架构具有较高路径多样性和容错性能。

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 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.
