Embodiment Construction

[0024] As previously mentioned, conventional header compression / decompression techniques do not destroy the integrity or functionality of a given header field, since this header field is completely reconstructed (at least ideally) at the decompressor side. Also as mentioned above, recalculation / change of header fields at each router does not destroy the functionality or integrity of a given field, since such recalculation / change is actually part of the functionality of this field.

[0025] Any other manipulation of header fields is traditionally prohibited. This is for two common reasons: (1) to avoid breaking the integrity of the field; and (2) to avoid interfering with the functionality of the field. Furthermore, since reason (1) was taken as the only reason to justify prohibiting manipulation of header fields, reason (2) above was never actually considered. However, the inventor considers that reason (2) above is the only fundamental reason not to manipulate header fields,...

Abstract

In packet communication paths that include header compression, header fields of packets to be communicated are altered. The alteration of the header fields does not disturb their functionality, and is transparent to the header compression scheme of the packet communication path. The altered header fields are provided for compression by the header compression scheme, resulting in improved performance of the header compression scheme. Performance improvements can also be achieved in packet communication paths that do not use header compression, by violating the integrity of header fields in packets to be transmitted over the packet communication path.

Description

field of invention [0001] The present invention generally relates to packet communication, and more particularly, the present invention relates to the purpose of improving the performance of packet communication by manipulating header fields. Background of the invention [0002] Due to the great success of the Internet, an Internet Protocol based on many different types of packet communication links, namely IP, was adopted (see Jon Postel, Internet Protocol, DARPA RFC791, September 1981, incorporated herein by reference; and Steven Deering and Robbert Hinden, Internet Protocol, Version 6 (IPv6) Specification, IETF RFC 2460, IETF IP Next Generation Working Group, December 1998, incorporated herein by reference) has become a desirable but challenging task. Internet protocols are commonly used in conjunction with transport protocols such as Transmission Control Protocol, or TCP (see Jon Postel, Transmission Control Protocol, DARPA RFC 761, Jan. 1980, incorporated herein by refe...
