| 摘 要： | 为了在Internet上提供有服务质量等级和保证的服务，现在已经提出的在传输层上的实现方案包括综合业务（Integtated Services）和区分业务（Differentiated Services)。本文分析了两种方案的体系结构、工作原理和服务类型，比较了二者在设计思想、实现机制、QoS特性等方面的差异和优缺点，介绍了两种模型相互结合的扩展体系结构及最新研究进展。

| Abstract: | IETF proposed on transfer layer two new architectures: Integrated Services and Differentiated Services. This paper analyzes their frameworks, functional blocks, principles and services provided; and then the pros and cons of individual philosophies, implementing mechanisms and QoS characteristics are presented, as well as an extended hybrid architecture compromised in terms of implementing and QoS characteristics is put forward. |
