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.
Abstract
In narrowband conditions,there are constraints such as low data transmission rate,commu-nication susceptibility to interference,data transmission interruption,and unstable communication net-work 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 detec-tion and state establishment,message acknowledgment and timeout retransmission,a reliable trans-mission 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 trans-mission in narrowband condition,and it can reduce the network load.
