LINK SPEED FLUCTUATION REDUCTION

摘要

Link speed fluctuation reduction can be useful in a variety of communication systems. Such smoothing may have various benefits and may be achieved in various ways. For example, a policy and charging rules function can be leveraged to avoid repeated transfers of a same section of over-the-top video. A method can include detecting, for a link, a link traffic condition above a predetermined threshold. The method can also include estimating link speed to obtain an initial link speed value. When the detected link traffic condition is above a predetermined threshold, the method can further include limiting fluctuation of the link speed to within a threshold amount of the initial link speed value. The method can additionally include periodically re-estimating the recently achieved link speed as an updated link speed value and limiting the fluctuation based on the updated link speed value.
