【摘要】 本文较为详细地归纳和介绍了在IP网上为保证实时业务传输的几种典型的QoS机制（如RSVP、IEEE802．1p、IPPrecedence和PACE等）的特点、工作机理和实现方式．分析了IP网上实时业务传输系统的体系结构，并给出了利用QoS机制实现Intranet上实时业务的传输系统的例子，同时对该系统的性能作了论证分析．更多还原

【Abstract】 This paper summarizes several typical QoS mechanism, such as RSVP, IEEE802. 1p,IP Precedence and PACE, to support real-time traffic transport, together with their features and realization methods. The transport system structure of integrated service based on IP is analyzed and an illustrative example is presented. We also construct and demonstrate the performance of the system.更多还原
