摘　　要：在战术通信系统中,一发多收的组播业务的应用越来越广泛。战术通信中的组播业务往往要求具备高适变性和高实时性,而民用网络中的IP组播、应用层组播均存在一定局限性,无法满足这些要求。针对这个问题,通过对现有IP组播和应用层组播技术特点和不足进行分析,提出了一种基于自定义协议和名址分离的战术通信数据组播设计与实现方案,可以很好地应对战术通信系统的高实时性、低带宽、高动态等特性需求。试验验证了此方案下组播业务需求的满足情况,测试结果表明,所提出的方案可有效提高组播数据在战术通信系统中的传输效率,为战术通信系统的通用组播方案设计提供了参考。In a tactical communication system,the application of the primary revenue multicast business is being used more and more widely.Group broadcast business in tactical communication systems often requires high variability and high real-time,however,both the IP multicast and the application layer multicast in the civil network have certain limitations and so they cannot meet these requirements.For this issue,this paper analyzes the characteristics and shortcomings of the existing IP multicast and application layer multicast techniques,and then proposes a group broadcast design and implementation scheme of tactical communication data based on custom protocol and address separation,which can respond well to the high real-time characteristics,low bandwidth and high dynamics of the tactical communication system.The satisfaction of the multicast business requirements under this scheme is verified.The test results indicate that the proposed scheme can effectively improve the transmission efficiency of multicast data in the tactical communication system and provides a reference for the design of general multicast scheme of tactical communication system.
