摘　　要：针对一般网络流量监控商业软件普遍存在兼容性差,难于满足特定局域网络监控要求,网管人员很难有效监控网络的数据流走向、各个网络结点间的数据流状况及其他网络异常情况,并且软件价格昂贵。根据局域网线路数据流量测量和分析的实际需求,设计了基于SNMP的计算机网络流量监控系统通用方案,介绍了在VC++6.0平台下利用SNMP++技术和管理对象库M IB开发网络流量监控系统的过程,较好地解决了流量数据采样中遇到的技术问题。通过仿真测试,该系统所生成的流量图与MRTG生成的流量图基本一致,而且该系统实现简单、工作可靠稳定,可以作为开发局域网络监控系统软件的范例。The compatibility of general commercial software of network traffic monitoring is poor, hard to meet a specific local area net- work monitoring requirements. Network managers are very difficult to monitor effectively the network data flow direction .the state of data flow among every network node and other network abnormal. Inaddition, the software is expensive. In this paper, according to the actual requirement of the measurement and analysis of the local area network data traffic,design a universal program of network traffic monitoring system which is based on SNMP. The paper also detailed describes the development process of the network traffic monitoring system by using SNMP＋＋ technology and Management Object Library MIB in the VC＋＋6.0 platform. It solves well the technical prob- lems in data sampling. By simulation testing, the traffic chart generated by this system is essentially same with the traffic chart generated by MRTG, the implementing process of this system is simple. Furthermore, system run is reliable and stable. This system can be used as an example of the software development of the local area network monitoring system.
