共享存储器交换机的性能分析

Performance Analysis of Shared Memory Switch

交换机是分组网中的一个重要组成部分,对于分组网的性能有着很大影响。介绍共享存储器交换机的三种不同实现方法以及多播的实现过程,同时以排队论的知识为理论分析基础,介绍排队论中的生灭过程模型,状态转移模型和爱尔兰呼损模型,并对状态转移的稳态特性以及共享存储器结构的交换机的丢包率公式给出推导。对所做的工作做简要的总结,并指明未来的研究重点。

Switch is an important part of packet network, which also has strong influence on the perfor- mance of packet network. Introduces switch＇s muhicast and three different schedules to imple- ment shared memory switch, describes birth and death process module, state transition module and the Irish call loss module in the queuing theory, then uses queuing theory to analyze steady-state characteristics and shared memory switch＇s cell loss possibility. Concludes the work and shows research priorities in the future.
