ALL-OPTICAL WDM PACKET NETWORKS

This paper describes the components and subsystems for the inplementat ion of a multi-GHz optoelectronic data transport network using self-ro uting packets in a multi-hop network. The short packet payloads are co mpressed using optical wavelength division multiplexing techniques, an d remain optical from source to destination while traversing the switc hing nodes, The routing is done with a lean, self-routing hot potato p rotocol in order to avoid the need for data storage at the switching n odes and to provide a fu;ed node latency equivalent to a few meters of fiber, Sustainable throughput both into and out of the electronic hos t at each node should exceed 10 Gb/s, Some technical details of the sw itching nodes and interfaces of the recirculating shuffle network, and the stepped wavelength laser arrays and testbed will be given.
