摘要
针对TCP/IP骨干网,提出一种新的基于业务流量周期规律特性的建模与异常检测方法.该方法通过挖掘骨干网主要业务流量的规律性,结合时间序列分析方法,有效地预测流量的变化趋势,避免了对复杂的流量非线性趋势进行建模分析.
A new approach to model service traffic and performe anomaly detection on TCP/IP backbone in the perspective of periodic traffic feature was proposed. This method avoids the difficulty to model the uncertainty and nonlinear facts in traffic data and provides more accurate information than the thresholds-based detection method.
