摘要： 网络分为无连接与面向连接两种服务类型。IP与ATM是这两种服务类型的主要代表。无连接的IP在浏览器、电子邮件等非实时的服务要求等方面更有效。但对于有高质量要求的实时服务传送中，ATM是一种更好的选择，这两种服务类型不可能相互取代。对实现两者有效结合的两种策略进行了探讨。

Abstract: Networks include connectionless and connection-oriented service types, in which IP and ATM can be as major examples of the two types. Connectionless IP is more efficient for browser, email, and other non-real-time services, but for services in real-time delivery with high quality, ATM is a better choice. However, neither can be replaced by the other. This article explores two strategies for implementing integration of ATM and IP.
