| 摘 要： | 为了在MPLS网络中使流量分布趋于合理，提出了一种基于CR-LDP(限制路由标记分配协议)中TLV(类型长度值)的流量工程实现策略及算法。该策略通过对网络资源属性和业务流属性的综合考虑，依据对特定业务流进行裁决的判别函数，将适于迁移的TLV结构业务流进行合理地及时迁移，从而达到提高网络资源利用率的目的。仿真结果验证了该策略及算法的正确性和有效性。

| Abstract: | In order to distribute the traffic in reason for MPLS networks,this paper proposes a new kind of strategy and algorithm based on the type length value in constraint route-label distribution protocol for implementing traffic engineering.Considering the attributes of network resource and the attributes of traffic flows synthetically,the strategy can transfer the suited traffic flows of TLV structure in time and enhance the utilization rate of network resources according to the estimation function for certain traffic flows.Furthermore,the validity of the strategy and algorithm is verified by simulation. |
