摘    要:IP QoS已成为IP网络的核心技术。目前实现IP QoS的机制主要包括有多种,例如子带宽管理、MPLS、IntServ、DiffServ等,可以结合起来实现更完善的IP QoS。目前,比较一致的看法是在网络边缘采用IntServ,在网络主干采用DiffServ。我们在局域网自适应IP QoS基础上,进一步研究了基于DiffServ的IP QoS.本文给出一种DiffServ结合IntServ实现彻底的端到端的IP QoS网络框架,提出了DiffServ实现自适应IP QoS管理的框架与方案,讨论了内部路由节点自适应QoS控制策略。最后讨论基于网络仿真软件NS2的一个简单实验结果。

关 键 词:DiffServ  IntServ  服务质量  IP网  局域网  Internet

Abstract:IP QoS (quality of services) is one of the core technologies of IP network. There are many kinds of mechanism to achieve IP QoS, such as Sub Bandwidth Management (SBM), Multiple Protocols Label Switching (MPLS), Integrated services (IntServ), Differentiated Service (DiffServ) and so on, but some of the above should be integrated for implementing complete IP QoS. At present, one of the most popular ideas is to adopt IntServ on the edge of network and DiffServ on the backbone. We propose an IP QoS management framework for complete end-to-end adaptive QoS by integrating DiffServ with IntServ, and put forward an adaptive control algorithm of IP QoS on DiffServ Interior Router nodes. An experiment result based on NS2, a network simulator software system, is discussed.
Keywords:IP QoS  DiffServ  IntServ  adaptive  multimedia resource management
