Research On Data Access Problem Of HF Integrated Service Network And Military Integrated Information Network

The interconnection between HF integrated service network and military integrated information network is conducive to the rapid transmission and sharing of important information.But the network characteristics of HF integrated service network and military integrated information network are quite different.At present,there are still some problems in practical equipment application,such as high delay rate and high loss rate.In order to effectively utilize the HF integrated service network and the military integrated information network interconnection network to carry on the data transmission,displays the equipment the better efficiency,and optimizes the transmission method.Firstly,the network characteristics and communication protocols of HF integrated service network and military integrated information network are compared.And the transmission process of data in HF integrated service network and military integrated information network is analyzed theoretically.Secondly,under the existing conditions,in order to give full play to the better efficiency of equipment,the experimental platform of HF integrated service network and military integrated information network is built.The network transmission characteristics of HF radio under different operating modes are tested,and the relationship among the optimal packet size,transmission rate and packet loss rate is obtained.This paper seeks and verifies the efficient data transmission mode suitable for the HF integrated service network and the military integrated information network,and proposes the selection of the HF radio working mode,which improves the transmission efficiency of the Internet and has guiding significance for the application of military equipment.In view of the unreliability of UDP protocol,a "confirm retransmission" method is proposed to improve the reliability of data transmission.Finally,some reasonable Suggestions are put forward for the equipment upgrading and transformation,so as to realize more effective data transmission between the HF integrated service network and the military integrated information network,and to build a simulation platform for the HF integrated service network and the military integrated information network.By analyzing the internal communication mechanism of TCP,a method of data transmission using TCP protocol in this Internet network is proposed,and the availability of this method is verified.By analyzing the internal communication mechanism of TCP,a method of data transmission using TCP protocol in this Internet network is proposed,and the availability of this method is verified.Aiming at the low reliability of UDP and the characteristics of the network environment,a SUDP is proposed for the interconnection of HF integrated service network and military integrated information network to improve the reliability of data transmission.Compared with TCP,UDP and AUDP which can improve the reliability of UDP,it is concluded that SUDP protocol improves the reliability to some extent compared with UDP protocol.Compared with TCP and AUDP,it improves transmission efficiency on the basis of maintaining reliability.
