摘要
网络流量监控程序一般都采用,简单网络管理协议(SNMP)对网络设备的流量数据进行间断的读取,以保证所有联网设备的数据都能被获取,鉴于网络流量监控间断扫描的特点,提出一种应用插值算法对离散点间的流量进行计算的方法,从而近似逼近间断时间点的真实网络流量,进而可对网络流量监控的时间粒度进行细化。呈现了几种插值算法在网络流量监控中的实际效果。
In order to guarantee data acquisition from all networked devices, the network flow monitoring program uses Simple Network Management Protocol （SNMP） to read the flow data in intervals. Aiming at the characteristics of intermittent scanning in network flow monitoring, a way of computing network flow using interpolation in intervals was proposed. Then the nearest approximation of network flow in a specific time could be obtained. And the intervals between scanning will seem short. The effectiveness of using interpolation in network flow monitoring will be shown as an instance.
