提出一个新分析模型来计算有业务量疏导能力的波分复用 (WDM )网格网的呼叫阻塞概率 ,WDM网络中的业务量疏导定义为复用、解复用和交换低速率业务量到高容量光路的行为 .该模型首先把原始网络分解为单个子系统 ,然后再对这些子系统进行独立分析 ,最后对这些子系统的结果进行适当组合得到整个网络的解 .同时 ,模型考虑了链路负载和链路阻塞事件之间的相关性 .仿真结果表明该模型给出的结果较准确 .
A new analysis model is proposed to calculate the call blocking probability of a WDM mesh with traffic grooming capability. Traffic grooming in WDM networks is defined as multiplexing, demultiplexing, and switching low rate traffic to High-capacity optical path. In this model, the original network is decomposed into a single subsystem and then the subsystems are analyzed separately. Finally, the solutions of these subsystems are obtained by the appropriate combination to get the solution of the whole network. At the same time, the model considers the chain The correlation between load on the road and link blocking event.The simulation results show that the model gives more accurate results.
