Abstract
A method and apparatus for eliminating the inefficient use of network bandwidth cause by numerous acknowledgment transmitted by the receiver to the transmitter by providing sparse feedback from the receiver to the transmitter indicating receipt of packets having headers to be used as reference headers. In the invention, upon receipt in the receiver of a packet having a reference header, a feedback is provided to the transmitter indicating receipt of the packet having the reference header. Thereafter, the receiver waits a predetermined period of time before providing another feedback in response to another packet having a reference header. The predetermined period of time allows time for the feedback to be received by the transmitter and for information from the transmitter indicating receipt of the feedback to be received by the receiver.
