摘　　要：基于应用层中继的多径传输系统(MPTS-AR)是一种基于应用层中继的多径传输系统,通过基于用户数据报协议的中继服务器构建端到端的多径传输条件,并可支持多种业务实现多径传输.提出基于OMNeT++平台上的INET Framework实现MPTS-AR网络仿真的方法,包括用户代理、中继服务器和中继控制器等网络逻辑实体的二次开发方法、相关网络链路和网络拓扑的构建方法、消息定义与处理方法等;讨论了应用程序接口兼容和多业务支撑等重难点技术.最后,通过H.264业务传输实例验证了所设计MPTS-AR网络仿真的正确性和有效性.Muhipath transport system based on application-level relay （MPTS-AR） is a multipath trans- port system model based on application-level relay. It uses user datagram protocol relay server to establish multiple paths for point-to-point session and supports multiple services. A method was proposed to create MPTS-AR network simulation basing on INET Framework of OMNeT ＋ ＋ platform, including how to cre- ate network topology, to implement logical entities （user agent, relay controller, relay server） , and to define and process messages. The key and difficult points about application program interface compatibili- ty and supporting multi-service were also discussed. H. 264 service based simulation was carried out. It is shown the correctness and effectiveness of MPTS-AR network simulation.
