Abstract:
A method for controlling congestion in an internetwork having a first segment and a second segment coupled by a router, the internetwork having a connection between a source and a destination, comprising the steps of:(a) receiving at the router a first acknowledgment associated with the connection, the first acknowledgment indicating a first window size for the connection based on an advertised window size of the destination; (b) adaptively determining a second window size associated with the connection based on an average buffer occupancy and an instantaneous buffer occupancy of the router, the second window size being not greater than the first window size; and (c) sending from the router the second acknowledgment indicating the second window size, wherein the average buffer occupancy is a function of average buffer occupancy just before time T, and instantaneous buffer occupancy at the time T.
