摘　　要：由于网络带宽的限制,引起网络拥塞,从而无法保障数据流的服务质量。提出了一种新的基于协调数据流的MPLS网络抢占方法TPN。TPN提出了以数据流作为抢占的依据,并对优先级重新分类,对被抢占的带宽进行协调选择,从而减少了对网络的影响。理论分析和仿真实验结果表明,TPN机制能够快速的调控传输中的数据流以及保证高优先权的服务质量,较好地解决了MPLS网络拥塞问题。A network congestion and unable to guarantee the quality of service traffic flows thanks to the network bandwidth constraints. A traffic flow preemption with negotiation based MPLS preemption mechanism is proposed. The TPN advances that it should occupy the bandwidth depending on the traffic flows, and reclassify the priority, then select the occupied bandwidth unisonous, thereby, it can reduces the impact on the network. Theory analysis and simulation show that TPN can control the transmission flows quickly and guarantee higher-priority quality of service, then solve the congestion problem of MPLS network significantly.
