Experimental demonstrations of interworking between an optical packet and circuit integrated network and OpenFlow-based networks

We propose a mechanism for achieving interworking between an optical packet and circuit integrated (OPCI) network and OpenFlow-based networks. Due to the ability of the OPCI network to provide both optical packet switching (OPS) and optical circuit switching (OCS) on the same fiber infrastructure, flows requiring high quality of service can be transferred on lightpaths, while other flows are transferred on large-capacity OPS links. We implemented the interworking function on an OPCI multi-ring network environment and an OpenFlow-enabled network-service testbed. In experiments on Internet Control Message Protocol (ICMP) sending/receiving between end-hosts, we achieved successful interworking between the OPCI network controls and OpenFlow.
