摘　　要：文章在一些研究成果的基础上,对IntServ/RSVP体系与DiffServ体系协议相结合的机制进行了探讨。进一步讨论了基于DiffServ体系的IP骨干网的两种管理方案,即动态管理方案和静态管理方案。通过分析得出结论,在基于DiffServ体系的控制环境下采用动态管理方案是实现QoS保证的最佳技术,由此提出了一种DiffServ/RSVP体系作为IP骨干网的方案,并对任意进出IP骨干网的IP分组按策略添加新分组头和按位判别法实现QoS保证的技术。This paper is based on some research resuhs,studies the mechanism that IntServ system and DiffServ/RSVP system agreement are combined,more discusses IP backbone＇s management project of two kinds of resourceses based on DiffServ,namely dynamic management project and static state management project.Pass the analysis conclusion,adopting dynamic management project is the best technique that realizes QoS＇s guarantee based on DiffServ system to control the environment,from here brings up a kind of DiffServ/ RSVP system for IP backbone as a mechanism that realizes QoS guarantee.This mec.hanism adds new packet headers to IP packets according to a policy and differentiates IP packets according to the bits.
