A hybrid waveband routing algorithm in WDM optical networks

波长/波带混合交换是WDM光网络中的一个新的研究热点。提出了一种在WDM多层多粒度交换网络中新的跨层交换路由算法—最大波带链路路由算法。该算法最大限度地利用波带交换链路和波带/波长混合交换链路的容量,仿真表明该算法能降低阻塞率,有效提供网络性能。

Hybrid waveband/wavelength switching in wavelength-division-multiplexing （ WDM ） optical networks is gaining more and more academic attention. In this paper, we propose a novel cross-layer routing algorithm, maximum waveband link routing algorithm （MWLR） , in waveband switching-enabled optical networks. Through extensive simulation MWLR algorithm can significantly improve the performance in terms of reduced call blocking probability.
