中文摘要：
为解决波分复用（Wavelength Division Multiplexing,WDM）网络中实时性业务流疏导问题,提出一种考虑了网络端对端延迟的疏导算法。建立了WDM网络模型和实时消息模型,用网络演算理论分析了有连续时隙和没有连续时隙分配下实时消息的端对端的最大延迟,并推导出了算法的延迟关键性参数时隙距离。提出的实时性疏导算法不仅考虑了最大利用率时隙优先以提高网络的负载,同时考虑了时隙距离和的关键参数,保证了实时消息的延迟性能。仿真结果表明了该算法的低延迟特性和低阻塞率特性。
英文摘要：
To solve the problem of real-time traffic grooming in WDM network,a novel algorithm considering the maximum end to end delay was proposed.The WDM network model and real-time message models were established to analyze the end to end delay under the circumstances of static location time slots and dynamic location time slots based on network calculus theory.The key factor called distance of slot was achieved from the expression of delay.The real-time grooming algorithm took into account of the sum of distances of slots as well as the improvement of network load by locating maximum utilization time slots,thus the delay performance of real-time message was guaranteed.Simulation results show that our algorithm has lower delay and higher throughput compared with other algorithms.
