本文报告了一个高性能的城域和核心路由器的比特率调整的调查。使用EWMA（指数加权移动平均）响应于业务负载来控制比特率，其中参数设置为使调整的性能影响最小化。调整的目的是实现节能。我们的计算表明，22.5%的功率节省是可以实现的比特率调整，而没有显着的性能下降。
This paper reports on an investigation into bit-rate adjustment on high capability metro and core routers. The bit-rate is controlled in response to traffic load using EWMA (Exponential Weighted Moving Average), with parameters set to minimize the performance impact of the adjustments. The purpose of the adjustment is to enable energy savings. Our calculations show that 22.5% power saving is achievable by bit rate adjustment without significant performance degradation.
