Photonic Fast Packet Switching Using Optically Processed Control
Abstract
In this research program, we have studied architectural and performance modeling issues which are central to the development of high-speed optical networks. We have focused primarily on the architecture of a broadband photonic packet switch. The use of optical processing to perform switch routing functions permits real-time routing of packets at high speed. The architecture of a 2x2 photonic packet switching node using optically-processed fixed- directory routing, contention resolution (using deflection routing), and synchronization was investigated, and is presented in detail in this final report. Deflection routing is well-suited for contention resolution using processing technologies in which buffers are expensive or not available, as is presently the case with optical technology. Simplified optically-processed self- routing procedures are found for banyan (baseline, shuffle-exchange and crossover) and lattice networks. Although lattice networks require a larger number of switching elements than banyan networks, they have a simpler interconnection field, and unlike banyan networks, the self-routing rule for lattices can avoid any internal blocking.
