通信网络的大规模建设给通信设备的管理带来了严重的问题,现有通信网络或不支持网管,或是存在很大弊端的串口网管。介绍源代码开放的嵌入式操作系统μClinux开发平台的构建,提出在μClinux上实现支持网络管理的重要协议SNMP且扩展SNMP代理来管理通信设备,并详细地介绍SNMP代理扩展方法。最终,在控制成本的基础上实现了对通信设备的方便安全的管理。
The large-scale construction of communication network has brought serious problems to the management of communication equipment. The existing communication network does not support the network management or the serial port network management with great drawbacks. This paper introduces the development of μClinux, an embedded operating system with open source code. It proposes to implement SNMP, which is an important protocol supporting network management, on μClinux, and extends SNMP agent to manage communication devices. It also introduces the SNMP agent extension method in detail. Finally, on the basis of the control cost, it is convenient and safe to manage the communication equipment.
