ATM基本概念和交换原理

Basic Concepts and Switching Principles of ATM

异步转移模式（ＡＴＭ）是ＣＣＩＴＴ选定作为Ｂ—ＩＳＤＮ的交换和复用技术。ＡＴＭ在物理信道上用固定长度的信元（Ｃｅｌｌ）进行复用和交换。本文对ＡＴＭ的概念和工作原理作了概括介绍。

Asynchronous Transfer Mode is the switching and multiplex technology selected by L-CCITT for B ISDN, ATMmultiplexes and switches in the physical channel with cells of fixed length. This paper gives a general introduction to theconcepts and working principles of ATM。
