由于军事通信网的应用环境和业务流传输的特殊性,在研究军事通信网业务可靠性时,必须考虑节点类型以及节点之间相互关系的影响。根据节点类型和功能的不同,将节点分成侦察节点,信息处理节点,通信节点,指控节点,行动节点等五类节点。从指控节点之间信息传输的可靠性和非同类节点之间功能链的可靠性两个角度来评估军事通信网可靠性,并提出了一种综合评估方法。最后,通过实例验证了该模型的有效性和实用性。 Due to the particularity of military communication network application environment and service flow transmission, in studying the service reliability of military communication network, the type of node and the influence of the inter-node relationship must be considered. According to the different types and functions of nodes, nodes are divided into five types of nodes, such as reconnaissance nodes, information processing nodes, communication nodes, accusation nodes and mobile nodes. The reliability of military communication network is evaluated from two aspects: the reliability of information transmission between the accused nodes and the reliability of the functional chain between non-similar nodes, and a comprehensive evaluation method is proposed. Finally, the validity and practicability of this model are verified by examples.
