摘　　要：在光分组交换网络中,当同一时刻有两个或两个以上的分组以同一波长从同一端口离开光交换节点时就会出现分组竞争,采用不同的竞争解决方法对光分组交换网络性能会产生巨大影响。在光分组交换中解决竞争主要有光缓存、波长变换、偏射路由三种方式。详细阐述了这三种竞争解决方法的原理、实现方式及特点,并对今后发展趋势做出展望。Packet contention would occur when two or more packets are trying to leave the switch from the same output port in the same wavelength simultaneously in Optical Packet Switching Network.Adopting different contention methods will have a great effect on the performance of the networks.There are three ways to resolve packet contentions i.e.optical buffering,wavelength converter and deflection routing in OPS.In this paper,the three ways are discussed in detail,and we view the trends in the future.
