摘要 分析了在光突发交换网络中,光突发分组经过光延迟线组后产生的出端冲突问题,以及由此对突发数据包交换丢失率的影响,提出引入可调波长变换器的解决方案,并通过仿真实验加以验证。 In the paper, we analyse the problem of fiber delay lines output contention, when the bursts are delayed by fiber delay lines, and the bursts lost rate affected by the problem. The solution by introducing the tunable wavelength converter are presented and simulation results are given.
