摘　　要：提出了一种改进型光可分突发交换性能分析模型(Modified Optical Composite BurstSwitching,MOCBS).该模型考虑了截断剩余造成的影响,通过分析截断概率、平均截断剩余长度,得到截断剩余造成的分组丢弃概率,从而更准确地估计分组丢失率.在此基础上,推导出支持区分服务的POCBS(Prioritized OCBS)性能分析公式.仿真验证了MOCBS的准确性以及POCBS分析公式的有效性.A modified analytical model of Optical Composite Burst Switching（ OCBS） is proposed. This model （MOCBS） takes truncation residue into consideration, and obtains the packet loss probability caused by truncation residue through analyzing the truncation probability and the average length of truncation residue. Thus it can evaluate packet loss probability more accurately. Based on this, prioritized OCBS （POCBS） analytical formula supporting service differentiation is deduced further. Simulations verified the accuracy of the modified model,and the validity of POCBS formula.
