Traffic management in SDN-enabled optical packet switching intra-datacenter network

Slotted optical packet switching (OPS) is foreseen as future technology for intra datacenter network that will have to provide dynamic reconfiguration capacity, scalability, low latency and QoS guarantees to support fast growing emerging services. In this paper, we describe a prototype based on this technology and reconfigurable thanks to implementation of Software Defined Network (SDN) functions. We demonstrate plug-and-play network upgrade, reconfiguration capability within a few microseconds and low latency controlled within a few ns. Then we present how SDN functions can be distributed on-the-fly into the network through the control plane, again within microseconds.
