This paper studies the QoS guarantee mechanism based on MPLS traffic engineering, then analyzes the QoS performance through simuktions by using TCP and UDP as service models and throughput as the metric in the case of applying MPLS traffic engineering.

• 研究了基于MPLS流量工程的QoS保证机制,并以传输控制协议(TCP)和报文协议(UDP)为业务模型,以吞吐量为性能指标,采用仿真的方法对使用MPLS流量工程情况下的QoS性能进行了分析。
