A method and apparatus according to one embodiment of the invention are operable to detect the accumulation of redundant ACKs (acknowledgment signals) in a queue for streaming data packet units, and to delete a portion of the redundant ACKs to improve transmission efficiencies. In one embodiment, only the most relevant ACK is kept before the ACKs are processed for transmission. In an alternate embodiment, a ratio of defined that limits the maximum number of redundant ACKs that may be deleted. This ratio is based upon a transmission window size. The teachings of the present disclosure may also be applied to flow control in a more general sense in which a plurality of redundant signals responses are being transmitted after being aggregated.
