摘　　要：简要介绍了解决端到端QoS的IntServ(IntegratedService)方案及TOS/IPPrecedence方案 ,通过对这两种方案的局限性的分析 ,提出利用DiffServ(DifferentiatedServices)方案解决端到端QoS ,并且给出具体实现的方法 ,重点讨论了实现中的若干问题和策略 ,在此基础上对DiffServ与多协议标签交换MPLS的结合进行了研究 ;最后阐述了DiffServ的未来发展。Integrated Services and TOS/IP Precedence solution,which are used to solve end to end QoS,are briefly introduced. Differentiated Services solution is presented through analyzing the shortage of these two solutions, and concrete implementation of Differentiated Services is provided.Some problems and strategies in the implementation are mainly discussed.A combination of Differentiated Services and MPLS is studied,and the future of Differentiated Services is set forth in the end.
