<p>A method of communications over a network is specially adapted for improved transmission performance with reduced bandwidth requirements in communications networks which are low quality or have widely varied physical channel performance, for example, wireless networks (2). The method includes the steps of packetizing the payload (30) into a series of data packets (42), inserting header packets (41) at the beginning, middle, and towards the end of the series, transmitting the series, together with the header packets (41), receiving at least some of the packets (42) of the series and at least one of the header packets (41), and sending an acknowledgement (60). The acknowledgement (60) is either that all data packets and at least one header packet was received; that not all data packets were received and at least one header packet was received; or that some data packets were received, but no header packet was received. Retransmissions of data packets and the header packets, when such packets are not received, is minimized in order to limit the number of communications necessary to deliver an entire data payload.</p> |
