OBS网络中基于扩展Benes矩阵的节点串扰分析

摘要

光突发交换（OBS）的提出。一定程度上满足了对高速业务的需求，但由于交换结构中光路器件自身的特性以及信号的相互作用，其内部存在严重的串扰问题，阻碍了通信的进行，极大地限制了光突发交换的性能。为了进一步研究OBS光网络节点结构中的串扰问题。仿真模拟了OBS网络中基于扩展Benes光交换矩阵的节点串扰情况。证明了OBS网络节点结构中，光交换矩阵本身、输入输出光纤数和每根光纤中的复用波长数都会不同程度的引起串扰的变化。从而影响整个光通信网络的质量。%The putting forward of optical burst switching has met the demand of high speed business at a certain extent. Because of the characteristics of the light path device and the signal interaction, the structure exists serious crosstalk. The blocking for the communication is broughLTthe performance of optical burst switching network is limited. In order to further study the the crosstalk in OBS network nodes structure. Nodes crosstalk based on extended Benes matrix in the OBS networks is simulated in this paper. It is proved that optical switching matrix itself, the number of input and output optical fiber or the multiplexing wavelength number can bring the crosstalk change. So the quality of optical communication network is disturbed.
