摘要 Generally, the limitations of optical delay line and link capacity limit the switching efficiency in the photonic asynchronous transfer mode (ATM) switch. Under the constraints, a smart photonic ATM switch designed for high-speed optical backbone network should have some fast switching strategies so that the congestion can be avoided or reduced. In this paper, we will propose a novel smart photonic ATM switch architecture with a novel compression strategy. In the smart architecture, while more than two frames are destined for the same destination, the losers will be queued and compressed to reduce the degree of congestion. Therefore, not only the total switching time (TST) can be reduced but also the scarce buffer is able to store more incoming cells. To meet the high-speed switching performance, a simple and efficient compression decision algorithm (CDA) is proposed. The timing of employing compression strategy and the saturated performance of proposed strategy are analyzed. Simulation results show that compared to the conventional photonic ATM switch without compression strategy, the proposed strategy offers a much better performance in terms of queueing delay.
