We review our work on an intra-data center (DC) network based on co-deployment of optical packet switching (OPS) and optical circuit switching (OCS), conducted within the framework of a five-year-long national R&D program in Japan (∼March 2016). For the starter, preceding works relevant to optical switching technologies in intra-DC networks are briefly reviewed. Next, we present the architecture...
An energy-efficient, high-performance optoelectronic packet switching for intra-data center (DC) network is presented, in which hybrid optoelectronic packet routers (HOERs) are interconnected with 100 Gbps (25 Gbps×4 wavelengths) links. A novel “Express path (ExP)” is introduced to enable the flow control. Packets, which are a part of a flow, can be bypassed the intermediate nodes and directly forwarded...
