摘　　要：　突发包分割是光突发交换(OBS)中冲突解决的主要方法之一,针对基于just-enough-time(JET)协议的OBS技术,在分析已有的头部分割和尾部分割机制的基础上提出了两种新的机制:当前突发包分割机制和最小损失分割机制。分析和仿真表明,采用这两种分割机制可以有效地降低数据信息包的丢包率。Burst segmentation is an approach of contention resolution in optical burst switching technique. (Aiming) at the segmentation strategy of just-enough-time (JET) based OBS protocol, through analyzing the current segmentation strategies, two new segmentation strategies, current burst segmentation (CBS) and minimum waste segmentation (MWS), are presented. Through analysis and simulation we prove that CBS and MWS strategies can reduce packets loss probability obviously.
