摘　　要：研究了同步光分组交换网中光分组长度的设计及其对一些网络性能参数的影响,分别推导了光分组中开销所占比率、时延及光纤延时线长度与光分组长度的关系,并给出各自相应的理论分析和数值解析,为光分组中分组长度的设计做了基础工作。This paper deals with optical packet length designing and its effect on so me performance parameters in slotted optical packet- switched networks. The relation between overhead ratio and optical packet length is deducted, as well as the relation between delay and optical packet length, the length of fiber delay lines and optical packet length. Accordingly, the theoretical and mathematical analysis is made. The results are useful for determining optical packet length from the point view of the whole optical packet- switched networks.
