摘　　要：某嵌入式设备工作于TCP/IP体系的应用层,接收处理UDP网络数据,具备液晶显示功能,并接受SNMP网管的监控。针对其功能需求设计了软件实现方案,在主进程的网络数据接收侧,采用链表构建内存池,可快速接收和缓存数据;选用灵活的加载方式实现液晶显示功能,可根据配置文件进行菜单的逐级扩展;使用NET-SNMP构建V2版本的网管代理,实现GET/SET/TRAP功能。该软件方案可操作性强,具备一定的工程参考价值。An embedded device works in the application layer of TCP/IP architecture,receives and process UDP network data,has the function of LIQUID crystal display,and accepts SNMP network management monitoring.A software implementation scheme is designed to meet functional requirements of the embedded device.A linked list is used to construct a memory pool which can receive and cache data quickly on the receiving side of network data in the main process.Choosing a flexible loading method to achieve the LCD display function,in this way the menus can expand step by step based on the configuration file.NET-SNMP is used to build the NMS agent of V2 to implement the GET/SET/TRAP functions.The software scheme is operable and has certain engineering reference value.
