In this paper, we describe a novel congestion control scheme for high-speed networks. The scheme is based on periodic transmission through the network of time-stamped sampling packets that sense the congestion status of the network. Upon reception, the sampling packet delays are calculated, averaged, and used to determine the state of the network. The information on the state of the network is then used to drive the network adaptive admission control. The major advantage of the proposed scheme over conventional congestion control techniques is that it copes with traffic surges that are shorter than the network round-trip delay. This is achieved by controlling traffic admission with continuous estimate of the network state. The scheme is targeted toward networks that carry aggregated traffic, and can be applied to ATM-based networks.
