Abstract
Methods and systems for estimating the number of active connections in a node in a communications network are described. The node estimates the number of active connections, without maintaining state information on each connection in the node, by sampling one or more packets in a buffer in the node when the node receives a packet, determining the number of sampled packets that are associated with the same connection as the received packet, and estimating the number of active connections in the node based on the determined number of the sampled packets. The node stabilizes the number of packets in the buffer by estimating the number of active connections in the node based on a sampling of the packets in the buffer when the node receives a packet, determining a probability for discarding the received packet based on the estimated number of the active connections and the recent buffer occupancy, and discarding the received packet according to the determined probability.
