A method of controlling packet flow through a network node in a packet-switched communication network. At least three measurements of instantaneous queue size are obtaining and utilized to determine a traffic pattern's relative shape, absolute level, and absolute context over a more extended time period. An initial estimate of a future level of congestion is made from the shape, level, and context of the traffic pattern, and is then utilized to establish initial settings for traffic control parameters. An auto-tuning process further optimizes the settings by periodically re-determining the shape, level, and context of the traffic pattern based on updated measurements of instantaneous queue size. Potential changes to the control parameters are tested at a dynamically determined interval, and are accepted only if the changes result in improvements in network performance.
