Paper Abstract

This paper proposes a new 2x1 node receiver architecture for all-optical packet switched networks, whose basic principle can be extended to construct a larger buffer if more 2x2 switches and fiber delay lines (FDLs) are available. The most striking characteristic of the architecture is that the buffer is achieved by a combined use of feed-forward and feedback FDLs. We describe and analyze the concrete two-stage FDL architecture which is the cheapest and simplest multi-stage solution. As for control strategy, we demonstrate that bottom control strategy (BCS), which uses FDL that is arranged in the feed-forward form when both feed-forward and feedback FDLs are available, is a more robust solution against bursty and non-bursty traffic. Simulation results show that the developed scheme (1) performs well in terms of performance metrics such as packet loss probability; (2) has a simpler control requirement and a better packet loss probability than M-Quadro architecture.
