摘　　要：提出一种基于相交路径的多径数据传输策略。为节点接口添加属性,在转发平面控制接口的可用与否,依据接口到服务器最短路径距离以及可用带宽,采用多指标综合评价法计算节点上每个接口的权值,实现在节点上按比例分流兴趣包,实现分布式控制数据传输。仿真结果表明,该策略在内容下载时间、数据包时延、负载均衡等方面具有良好性能。A transmission strategy based on intersectant multi-path（IMPT）was designed.Additional attribute was defined to every face,node could manage whether the face was useful or not.The node could get the shortest distance from every face to sever and remainder bandwidth to calculate the weight vector.Every node can shunt the interest packet to the faces according to the weight vector and distributed control data transmission.Simulation results show that IMPT have good performance in NDN networks considering content download time,packet delay,load balance and others.
