The time-out control technology of multi-node data link transmission in ship communication network is studied, and the influence of real-time data transmission time on time-out transmission is considered to improve the time-out control level of data link transmission. According to the communication plan of the ship communication network, the multi-node data link automatically searches the network routing table to match the route. According to the queuing model of the ship communication network multi-node data link, the real-time data queuing waiting time and real-time data communication time of the multi-node data link are determined. According to the relationship among the shortest transmission time, communication time limit requirements and real-time transmission time of the data link, the configuration of the data link is updated by adjusting the communication power and frequency, and the routing table of the ship communication network is refreshed to realize the time-out control of the transmission of the multi-node data link. Experimental results show that this technology can effectively control the transmission timeliness of multi-node data link, and the real-time transmission time of data link is less than 5ms.
