Abstract
Techniques and systems for managing transmissions from a TCP source by regulating the flow of acknowledgement signals to the TCP source are described. An acknowledgement signal regulator monitors a data queue used to buffer data packets received from the TCP source and an acknowledgement signal queue used to store acknowledgement signals to be transmitted to the TCP source. An acknowledgement signal release manager determines the available space in the data queue and the expected number of data packets arriving at the data queue, and manages the release of acknowledgement signals from the acknowledgement signal queue to the TCP source so as to prevent an undesired overflow of the data queue resulting from the arrival of an excessive number of data packets from the TCP source.
