标记交换与ＩＰ交换都是多层交换技术，都是把ＡＴＭ第二层交换技术与第三层路由技术结合起来，提供ＩＰ的包传送。下面介绍ＩＰ交换与标记交换的基本概念。 一、ＩＰ交换技术与标记交换技术的概念 １．ＩＰ交换技术 ＩＰ交换（ＩＰ Ｓｗｉｔｃｈ）是Ｉｐｓｉｌｏｎ公司提出的
Tag switching and IP switching are multi-layer switching technology, ATM layer two are switching technology and the third layer routing technology to provide IP packet transmission. The following describes the basic concepts of IP exchange and label exchange. First, the concept of IP exchange technology and mark exchange technology 1. IP Switch IP Switch (IP Switch) is proposed by Ipsilon
