Abstract
Multi-channel network communication is improved by reducing the amount of data that is transmitted over connections that can stem from a similar source. Content of data packets transmitted from the source are reduced and the result is compared to previously transmitted data packets. If identical packets are found, then only an identification of the packet is transmitted. At the receiving side, the identification is used to identify a previously received data packet and use that as though it was the recently received packet. If a similar packet is identified, then the identification of the similar packet, along with change information is transmitted to the receiving side.
