Average Delay Analysis of An Input and Output ATM Switch with Multiple Priorities

本文通过对ＧＩＳ模型库系统的研究，讨论了ＧＩＳ应用模型的管理及ＧＩＳ应用模型发展中的若干问题。

This paper analyses an N×N nonblocking ATM input and ouput switch queueing with multiple priorities at input ports.The arrival process of each priority to each input port is Bernoulli with probability p 1,p 2,…,p R, and each class has a dedicated buffer with infinite size.The speed -up factor is S(B≤S≤N ),and the output buffer size is B with backpressure.Each cell has an equal probability 1N being sent to output ports.The average delay time of the considered approaches is derived by theoretical analysis and computer simulations.
