基于Linux嵌入式系统的网络管理模块的架构

In this paper, it mainly introduced the basic knowledge and traits of the Embedded Operating System Linux and the principals and features of Simple Network Management Protocol (SNMP), Management Information Base (MIB) and Structure of Managed Information (SMI). Combined with the Embedded System’s application in the Satellite Communications, I elaborated the process of the Network Management and designed a network management module based on SNMP. This Network Management Module is in the middle place of the network: to the manager of the outer network, it is the agent, who provides the MIB information or gives off warnings to the manager; to the devices of the inner network, it is the manager, who is in charge of the whole inner devices.
