We summarize our recent results on field trial of optical burst switching node prototype developed under NEDO-funded Photonic Network Project. Stable switching and transmission of 40/10-Gbps mixed-bitrate signals are achieved over 92-km 2-hop field testbed.
A novel high-speed correlator is proposed and demonstrated for packet-header recognition at 100 Gb/s. The system includes only linear optical components, operates with low optical powers, and is scalable to 1 Tb/s.
In modern packet switches, technology limitations may introduce switch configuration delays that are non-negligible compared with the time required to transmit a single packet. In this paper, we propose a methodology for scheduling of packets, in the context of these technology limitations. If the total tolerable delay through a packet switch is at least on the order of the switch configuration delay,...
The implementation of packet switched optical network architectures bring forth a set of new challenges in network node design. This paper discusses and demonstrates promising MicroPhotonic architectures that perform optical header recognition and reconfigurable add/drop multiplexing for future optical networks.
