报告内容:

Optical interconnection provisioning in Data Center (HPC system as well) draws lots of interests thanks to its high bandwidth provisioning capability and power efficiency. At the same time, since the throughput of traffic in DC is fluctuating through time, it is quite critical to adjust the optical connectivity and bandwidth allocation dynamically according to the actual traffic pattern. Compared with general MEMS enabled OCS connection, OTDM system with optical fast switch is an alternative way to provide optical interconnection but still keeping benefit from bandwidth/port sharing. Some recent research will be introduced including an OTDM based intra-rack interconnection with sFlow based elephant flow detection and an ultrafast DPDK based online connectivity and bandwidth allocator.
