摘　　要：经过分析多路径路由协议的实时性能,提出了一种信息分级的多路径路由(MP-IC)算法。该算法采用最小跳数法创建路由表,建立了可以中转节点选择概率模型,系统根据信息等级调整相关权值,以满足不同等级信息的时延和可靠性能要求。仿真实验表明:与EEAR,EAMMSPEED协议相比,该算法可以有效降低信息时延,具有较高的数据传输可靠性,在多业务流应用方面能够表现出良好的性能。Real-time performance of multi-path routing protocols is analyzed.An information classification-based multi-path routing algorithm is proposed.This new algorithm creates routing table using minimum hop numbers method,set up a probability model,where relevant weight could be adjusted based on the level of information,in order to meet such performance requirements as demand of time delay and reliability of different levels of information.Simulation results indicate that compared with EEAR and EAMMSPEED,the new routing algorithm provides shorter time delay and higher reliability of data transmission.It has good performance on business process context application.
