摘　　要：在窄带条件下,存在数据传输速率低、通信易受外界干扰、数据传输中断和通信网络状态不稳定等制约因素,如何更有效地传输数据是当前计算机网络传输协议的研究热点。通过建立数据分类、网络状态探测与状态建立、报文确认和超时重传等机制,提出了一种具备适应窄带条件的关键数据可靠传输方法。试验结果表明,该方法可有效提高窄带下数据传输的可靠性、实时性和高效性,降低了网络负担。In narrowband conditions,there are constraints such as low data transmission rate,communication susceptibility to interference,data transmission interruption,and unstable communication network status,etc.How to transmit data more effectively is the current research hotspot on transmission protocols of computer network.By constructing mechanism of data classification,network state detection and state establishment,message acknowledgment and timeout retransmission,a reliable transmission method for critical data adapted to the narrowband condition is proposed.Experiment result shows that the method can effectively improve reliability,real time and high efficiency for data transmission in narrowband condition,and it can reduce the network load.
