基于AFDX的MIB管理数据库的研究和实现

The Analysis and Implementation of MIB Based on AFDX

随着AFDX在航空电子的通信网络设备中被越来越多地使用,为保证AFDX网络中交换机和端系统的安全可靠,提出了基于AFDX的MIB管理数据库。结合AFDX网络的主要特点,分析了适合AFDX网络的MIB管理数据库的组织架构,定义了应用于AFDX交换机的MIB帧结构。通过对MIB管理数据库的深入分析,给出了适用于AFDX交换机的MIB设计方法,并在基于自主研发的AFDX的真实网络环境下,实现了AFDX网络的数据管理。

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.
