新一代IP QoS的实现

New Generation IP QoS Technologies

文章介绍了新一代IP骨干网上的IPQoS实现技术,论述了集成业务(IntServ)与差分业务(DiffServ)解决方案的特点,详细介绍了相关的队列管理与排队机制,并结合多协议标签交换(MPLS)技术的最新发展,阐述了综合多协议标签交换流量工程与DiffServ技术体系端到端IPQoS的实现。

This paper gives an overview of the IP QoS technologies for new generation IP ba ckbone networks. Two different IP Qos architectures-IntServ and DiffServ are di scussed with regard to queue scheduling and queue dropping mechanisms. Based on the latest development of MPLS technology, the MPLS DiffServ-Aware Traffic Engin eering solution scheme for end-to-end IP QoS is also presented.
