IP城域网流量预警模型研究

主要完成城域网网络流量监控系统的设计及其预警模型研究,采用SNMP协议监视网络性能、检测分析网络差错,可实现对网络中各种设备端口的流量进行采集,并将监控数据自动保存在数据库文件中。同时也可将记录的数据利用计算机技术图形化,按时间显示聚合组的流量情况。通过该软件可监控、分析记录对象的流量,确保对该监控对象的流量进行记录,并对流量不均衡、流量异常的对象进行预警提示。

Research on Warning Model for Metropolitan Area Network

A system for monitoring metropolitan area network traffic flow is designed and a warning model is studied.Based on SNMP protocol,the network performance and error are monitored,which can achieve the acquisition of network traffic flow for varieties of device ports,and the monitoring data is automatically saved in the database file.In addition,the recorded data can be transformed into the grapy by computer technology.Finally the rates of aggregation group are obtained by time.Through this software,the rates of recorded objects can be monitored and analyzed.If there are unbalanced or abnormal rates,this system will give warning prompts.
