The Designs of a Scalable Optical Packet Switching Architecture

This paper proposes a new switching architecture to be used in all optical packet switching networks. The proposed switch is derived from an original 2 × 2 two-stage multi-buffer switched delay line based optical switching node, known as an M-Quadro node. By incorporating bypass lines into the M-Quadro architecture and employing a novel switch control strategy, the optical packet switching node can effectively resolve packet contentions, thus reducing the packet deflection probability substantially. Furthermore, we show that such architecture is scalable for a generic multiple stages optical packet switch with a larger number of input/output ports.
