基于MPLS的DiffServ模型的网络QoS

The QoS of DiffServ Model over MPLS

对基于多协议标记交换(MPLS)的DiffServ模型的网络QoS进行探讨,采用NS-2软件仿真结果表明,MPLS和DiffServ结合明显改善了网络的服务质量和效率.

With the develoment of Internet, QoS importance has become great. IETF has defined two models for IP QoS.IntServ and DiffServ. DiffServ model was regarded to be promising well, and the combination of DiffServ and MPLS has been becoming the direction of Internet＇s development. This paper discusses the QoS of DiffServ Model over MPLS and simulated this model with NS-2. The experimental data obviously show that this model has a higher efficiency.
