摘要
为了评估网络流量情况,及时扩容拥塞电路,运营商普遍采用基于SNMP的网络流量采集方法,通过计算两次采集间隔的平均速率粗略估计电路流量。为了进一步定性分析流量突发情况,编写了实验程序,缩短采集周期,实现了秒级采集,使用不同采集周期的数据进行计算和对比分析,得到了不同采集周期下的峰值流量的比值,最后提出了更有效的运营商网络流量传统采集加触发式秒级采集的新模型,以期实现精准扩容和更加敏捷的流量调度。
In order to evaluate the network traffic and expand the congestion circuit in time,operators generally adopt SNMP-based network traffic collection methods to roughly estimate the circuit traffic by calculating the average rate of the two collection intervals.In order to further qualitatively analyze the case of bursty traffic,an experimental program is given to shorten the collection cycle to achieve second-level acquisition.Then the data with different acquisition cycles are used for calculation and comparative analysis,and the ratios of peak traffic under different acquisition cycles are obtained.Finally,via combining traditional method and triggering-based second-level one,a more efficient model of traffic collection for operator networks is proposed to achieve accurate expansion and intelligent traffic scheduling.
