The Research And Application Of Network Management And Data Loading Protocol Based On AFDX Network

With the rapid development of science and technology,some new technology such as computer technology and network technology are used in aircraft avionics system,which orientation is becoming flexible loading configuration,integrated and comprehensive.In the maintenance of avionics equipment,the digital information management and the high reliability of maintenance information data of the avionics equipment is particularly important.Therefore,it is of significance to study the network management and data loading protocol of AFDX(Avionics Full Duplex switched Ethernet)network.Network management technology has been developing rapidly since SNMP was published at the end of 1980 s.Since the enhancement of management functions and expanding of managed objects.It has become an essential link in constructing and maintaining networks.The ARINC615 data loading and unloading protocol which is defined by Aeronautical Radio Inc,and gives the implementation of the ARINC615 protocol based on specific hardware environment.Firstly,this paper introduces the development status of SNMP network management and ARINC615 A data loading;Secondly,the SNMP network management protocol and ARINC615 A data loading protocol are analyzed and introduced in detail;Thirdly,on the base of analysis of the SNMP network management protocol and ARINC615 A data loading protocol to design SNMP network management software and ARIND615 A data of loading and unloading software based on the AFDX network;Finally,the functions of SNMP network management software and ARINC615 A data loading software were tested in the AFDX network environment.This paper is designed a relevant software which is based on research of the AFDX network of SNMP network management protocol and ARINC615 A data loading protocol,the final test shows that the SNMP network management software and ARINC615 A data which are met requirements of the function of the software uninstall.
