Abstract:
An apparatus for enhancing performance of packet communications over a packet communication path that includes a header compressor, comprising:an input for receiving header fields of one of a plurality of packets to be communicated over the packet communication path; a field processor coupled to said input for altering one of said header fields to produce an altered header field; an output coupled to said field processor for outputting said altered header field to the header compressor for compression of said altered header field; wherein said field processor selectively alters said one header field and selectively provides to said output one of said one header field and said altered header field, and wherein said field processor includes a mapper for mapping a plurality of first values respectively associated with said header fields into a corresponding plurality of second values respectively associated with said header fields, said one header field associated with one of said first values and one of said second values, said one first value differing from said one second value.
