OpMiGua Hybrid Circuit- and Packet-Switched Test-Bed Demonstration and Performance

Hybrid optical network architectures that combine beneficial properties of circuit- and packet-switching are attractive for multimedia networks. We have already proposed and reported the experimental demonstration of elements of a hybrid optical network architecture, the OpMiGua network. We now report experimental characterization of a three-node OpMiGua network test-bed with ingress, core, and egress nodes. The experiment confirms zero packet loss and jitter of the circuit-switched guaranteed service transport class of service (CoS) and shows how adding a packet-switched statistical multiplexed CoS increases lightpath utilization
