ATM交换网技术

TECHNOLOGIES OF ATM SWITCH

文章较为详尽地介绍了宽带综合业务数字网Ｂ－ＩＳＤＮ的分层协议和ＡＴＭ交换技术，并分析了ＡＴＭ交换在Ｂ－ＩＳ－ＤＮ网络中的作用，ＡＴＭ采用随机时隙交换为特征，即只要时隙空闲即可插入进行交换，而不同于时分固定时隙交换，并能根据业务类型、速率的需要动态地分配有效资源；尽可能地克服了电路交换的低效性和分组交换的低速性，产生了高速、高效的信息传输和交换效果。

This paper describes in detail both B ISDN hierarchy protocols and technologies of ATM switch.The ATM′s characteristic is to switch with stochastic time slot other than that of the sequential,which results in the faster switch. The plays of ATM are given in B ISDN network.
