摘　　要：光分组交换网是全光网络发展的必然趋势.然而,光分组交换网络发展的瓶颈是光缓存技术.目前,在光域比较现实的还是采用光纤延迟线(FDL)作光缓存.重点研究了光纤延迟线光缓存技术,对FDL光缓存技术进行了深入的分析和归纳,并对每一种光纤延迟线光缓存调度策略的优缺点都进行了细致的分析.最后指出了光纤延迟线光缓存技术的未来研究重点和发展方向.The optical packet switching network is the necessary tendency in the development of all optical networks. But the bottleneck in developing the optical packet switching network is the optical buffer technology. At the present time, the most realistic approach is to use fiber delay line （FDL） as optical buffer. The FDL optical buffer technology is emphatically studied, analyzed and generalized further. The merits and faults of each FDL optical buffer technology are analyzed in detail. And the key issues and directions of future study in this area are pointed out.
