摘　　要：文章分析了IntServ/RSVP与DiffServ这两种IP网络的QoS保障机制的原理,并对这两种体系结构进行了比较,说明了各自的优缺点,同时也指出了这两种机制的适用环境。提出了一种利用扩展RSVP协议与MPLS技术相结合的基于IP网络的QoS保障机制。最后,给出了利用RSVP协议建立标记交换路径(LSP)的步骤。利用该方法可以很好地保障IP网络的QoS。This paper analyzes the principium of two QoS guaranteed mechanism s of IP network:IntServ /RSVP and DiffServ,and these two mechanisms are compared with each other on their advantages,disadvantages and applicable environments.An IP-based network QoS guaranteed mechanism combined with RSVP and MPLS technology is provided.Finally the process of establishing a label switch path(LSP)using RSVP is provided.Using this method,QoS of IP network can be guaranteed well.
