摘要
针对基于多协议标记交换的光突发交换网络在组网过程中存在传输性能劣化的问题,采用最坏值的方法,从典型光交叉节点的串扰特性入手,分析推导了网络中多个节点级联后同频串扰对传输性能的影响,并通过仿真进行验证.分析结果表明,核心节点级联产生的串扰累积是导致该网络传输性能劣化的重要因素.
Decreasing transport performance of GMPLS-Based OBS in network building was analyzed in the worst case. Based on crosstalk characteristic of typical optical cross-connect, the impact of homodyne crosstalk cascaded core nodes was derived and testified by simulating. The results show that crosstalk accumulation of cascading core nodes is an important factor to decreases transport performance of GMPLS-Based OBS network.
