基于ARUDP的指挥控制网络数据传输协议

针对目前指挥控制网络采用UDP协议进行大数据传输时存在长时延及高丢包率的问题,提出了一种基于UDP改进的ARUDP(Augmented Reliable UDP)协议。该协议针对UDP传输过程中存在的乱序到达问题,提出了基于乱序重构的管理机制,降低了丢包率;在接收端根据网络相对单向队列时延检测网络状态,并利用改进的A-AIAD控制方法自适应调整数据发送速率,减小了队列排队时延,提高了数据传输效率。仿真实验表明,ARUDP协议发送速率平滑,在保持UDP高效的前提下,提高了传输的可靠性和实时性,降低了网络的丢包率,提高了网络资源利用率。

Command and Control Network Data Transmission Protocol Based on ARUDP

Aiming at the command and control network using UDP protocol has the problem of long delay and high packet loss rate for large data transmission,an improved ARUDP(Augmented Reliable UDP)protocol based on UDP is proposed. The protocol for the exist in transmission process of UDP arrived disordered,an management mechanism of out-of-order reconstruction is put forward and the packet loss rate is reduced,detect the network status based on the network relative state one-way queue delay,and the use of improved A-AIAD control method of adaptive adjustment of the data transmission rate,reducing the queue delay and improve the data transmission efficiency. Simulation results show that the ARUDP protocol's sending rate smoothly while maintaining the UDP high efficiency. It also improves the transmission reliability and real-time,reduces the network packet loss rate and improves the utilization ratio of network resource.
