Abstract
A method for managing pending acknowledgement (ACK) packets in a communication device is provided. The method can include the communication device monitoring a status of a transmit queue for packets to be sent over a network; detecting a queue condition indicative of congestion causing a delay in sending one or more ACK packets pending in the transmit queue; and discarding a set of one or more ACK packets from the transmit queue in response to the queue condition. The discarded set of one or more ACK packets can include one or more oldest ACK packets of the ACK packets pending in the transmit queue. A most recent ACK packet pending in the transmit queue can remain pending in the transmit queue after the set of one or more ACK packets has been discarded.
