波分复用网络中的组播阻塞率分析

The Analysis of Multicast Blocking Probability in WDM Network

通过建立一个基于组合数学中容斥原理的理论模型,分析了波分复用网络中组播的阻塞率.为了修正计算结果的偏离,引入修正公式来完善已有模型.修正后模型的分析结果与仿真结果符合得较好.本模型的算法复杂度较低,同时也有一定的灵活性.

A theory model, based on the inclusion-exclusion principle from combinatorics, was built to analyze the multicast blocking probability in WDM （wavelength division multiplexing） network. In order to correct the departure of calculation result by the theory, a correctional function was introduced to modify the model. Analysis result of the corrected model shows more exact with the simulation. The algorithm complexity of our model will become deduced but the flexibility relatively increased.
