Method and apparatus for reducing redundant traffic in communication networks

摘要

A capability is provided for reducing or even eliminating redundant traffic in cellular wireless networks. A method is provided for encoding a target packet in a manner for reducing redundancy of information in the target packet. The method includes identifying a region of the target packet that matches a region of a stored packet, removing, from the target packet, the identified region of the target packet from the target packet, and inserting, within the target packet, an encoding key comprising a hash of the stored packet. A method is provided for reconstructing a packet from an encoded packet that is encoded in a manner for reducing redundancy of information in a network. The method includes identifying an encoding key within the encoded packet, wherein the encoding key comprises a hash of a stored packet, retrieving the stored packet using the hash of the stored packet, removing the encoding key from the encoded packet, and inserting information from the stored packet within the encoded packet.

1. A method for encoding a target packet, the method comprising:
using a processor and a memory for:
identifying a region of the target packet that matches a region of a stored packet, wherein the stored packet includes a header portion and a payload portion;removing, from the target packet, the identified region of the target packet; andinserting an encoding key within the target packet, the encoding key comprising:
a hash of the stored packet, wherein the hash of the stored packet is a hash of the header portion of the stored packet and the payload portion of the stored packet; andinformation that indicates positions of the matched regions in, respectively, the stored and target packets.
