摘要

研究了一种适用于宽窄带业务的ISDN用户接入策略。假设宽带业务被阻塞，而窄带业务被允许排队。每个用户可能需要随机数量的带宽单元(插槽)。给出了宽带用户的准确阻塞概率，同时给出了窄带用户的消息延迟的近似解。后一种解决方案是基于J.S. Kaufman(1981)和S.S. Lam(1977)的排队网络模型的乘积形式解决方案的扩展。

A performance study of a user access strategy for ISDN

An ISDN user access strategy for wideband and narrowband traffic is studied. Wideband traffic is assumed to be blocked, while narrowband traffic is allowed to queue up. Each user may require a random number of bandwidth units (slots). The exact blocking probability for the wideband users is given, while an approximate solution is given for the message delay of narrowband users. This latter solution is based on an extension of the product-form solution for the queuing network models of J.S. Kaufman (1981) and S.S. Lam (1977).<>
