摘要
该文首先提出了一种新颖的估计技术——dEWMA(doubleExponentialWeightedMovingAverage)。该技术采用两个EWMA估计器进行数据测量,克服了传统EWMA估计技术不能同时获得良好的时效性和平稳性的缺点,能够为相关应用提供更加准确、灵活的数据估计。其次通过在RED网关中应用dEWMA技术,对其有效性进行验证。仿真结果表明采用dEWMA的RED性能较之未采用dEWMA的RED有明显的改善。
This paper firstly presents a novel estimation technology ——EWMA （double Exponential Weighted Moving Average）, which employs two EWMA filters to measure data, overcomes the defect that traditional EWMA estimation technology does not achieve fine agility and stability, and provides much more accurate , flexible data estimation. Secondly, the effectiveness of dEWMA is validated by applying to RED gateway. The simulations show that the performance of RED with dEWMA is better than that of RED with non-dEWMA.
