Content storage and redundancy elimination

摘要

A method for reducing data traffic associated with the transmission of packets in a packet-based network including: a) maintaining data transmitted in a data stream at a network source (16) and destination (18), the network source (16) is in communication with the destination (18) via a network path (8); b) subsequently receiving a packet associated with the data stream at the network source (16); c) extracting the packet's data; d) comparing the data extracted in step c) with the data maintained in step a); and e) where the data extracted in step c) at least partially matches the data maintained in step a); f) sending a system packet to the network destination (18) identifying the data extracted in step c) with the data maintained at the network destination (18); and g) recreating the packet at the network destination (18) from the data maintained at the destination.
