摘　　要：提出一种多卫星链路消息分发处理的方法。该方法首先建立和维护全网成员状态表,利用该表能够直观地获取成员间拓扑关系、网络状态及链路质量等信息。其次给出卫星帧格式及协议转换流程,并提出多卫星链路下的链路选择方法,采用生命周期管理、优先级发送、重发机制等技术手段进行消息发送控制。最后提出该方法实现的具体技术途径,同时该方法已应用在实际设备中,运行结果表明该方法的正确性和可靠性。Proposes a method of message distribution processing for multi-satellite link. Firstly, this method establishes and maintains a member state table, which can obtain the topological relationships among members, network state, link quality and other information. Secondly, this meth- od presents the satellite frame and protocol conversion process, and the method of link selection under muhi-satellite link. It can control message sending using the technical means of lifecycle management, message priority and retransmission mechanism. Finally, presents the implement of this method and applies it to the actual equipment. The operation results show that the method is proper and reliable.
