基于ATM的网络互连方式

ＡＴＭ技术能否在数据通信网中广泛采用取决于其是否能高效地支持现有业务，其中主要为非连接业务。本文介绍了几种基于ＡＴＭ 的非连接业务支持方式和协议体系结构，对其进行了评述并对ＩＰ分组到ＡＴＭ信元的封装效率进行了分析。

The Internetworking Approaches Based on ATM

To ensure a wide acceptance of ATM in the data communication network, it is important that ATM supports existing applications, most of them are connection less, in an efficient manner.This paper introduces several approaches for providing connection less service in an ATM network. The protocol architectures of these approaches are presented and the rough comments are made on them as well. Finally, the efficiency of the encapsulation from IP packet to ATM cells are given out.
