摘要
在详细分析军事训练系统数据传输需求的基础上,基于统一建模语言(UML)对其网络管理部分进行建模。为提高网络传输的可靠性,设计了服务器端的身份验证环节,并提出了一种能够承载数据传输的基于心跳机制的连接状态侦测方法。进一步详细设计了底层数据报结构,并对其标识进行编码,减少了数据冗余。测试结果表明,该网络体系在保证实时性的基础上具有较高的可靠性,可以为同类系统的网络体系设计提供有益参考。
In the detailed analysis of the data transmission needs of the military training system,the network management is modeled based on unified modeling language（UML）.In order to improve the reliability of network transmission,authentication part is designed in the server side,and a connected state detecting method is proposed,which is based on heartbeat mechanism and with data-carrying.Further,the substructure of datagram is designed in detail,and its flag is coded and data redundancy is reduced.Test results show that the network system has got higher reliability while satisfying the real-time constraints.A certain valuable reference is provided to network system designing of the similar corresponding systems.
