摘要
文章研究了波分复用(WDM)光网络中动态业务下的波长分配问题,在无波长转换器的条件下提出了一种新的波长选择算法。该算法在支持多优先级的动态门限法的基础上,通过延后使用资源较少的链路上的波长以减小阻塞率。仿真结果说明了该算法的有效性。
In this paper, wavelength assignment in WDM optical networks with dynamic traffic is studied, and a new dynamic wavelength is proposed without wavelength conversion proposed. By using dynamic threshold method, the proposed algorithm reduces the blocking probability through putting off the use of the scarce resource. The simulation results show that the proposed algorithm is effective.
