Abstract: Based on the increase of AFDX application on avionics communication devices, Management Information Base is proposed to insure the safety and reliability of data between switch and end-system. This paper introduces main characteristics of AFDX network, analyses system structure of MIB suitable for AFDX network, defines structure of MIB frame used for AFDX switch. Especially, through deeply researching MIB. a design method is presented for MIB applied in AFDX switch. In a real AFDX network environment which is independent designed, information management is implemented successfully.
