【摘要】 研究了光突发交换边缘路由器上的突发装配,提出了带安全间隔的突发装配具体实现算法,同时为体现通用性引入了单位化输入比特率的概念,以适应不同实际网络中的最小分组长度和输入比特率.基于这一算法,通过网络仿真,讨论了在自相似流量时,包括突发长度极值、装配时间阈值等在内的各类参数设置对突发产生、突发长度分布、分组丢失率、输出数据总量及有效信息率等的影响.更多还原

【Abstract】 A novel burst assembly algorithm with safety space is proposed for optical burst switching in edge routers.Moreover,a concept of unit input bit rate is introduced to improve universality.Based on this algorithm and self-similar traffic,the assembly process is simulated.Influences on burst creation, burst length distribution,packet loss ratio,total output data,and valid information ratio are discussed by setting appropriate parameter values including ultimate burst lengths,assembly time threshold,etc.更多还原
