Method and system for improving bandwidth availability in a data communication network by tokenizing messages

A message compressor for compressing a message to obtain a compressed message suitable for transmission via a data communication network, said message compressor comprising:

• means for mapping each of one or more fields present in the message with a respective tokens;
• means for, after said mapping, determining at least one token representing a field that is present in the message and at least one token representing a field that is absent from the message;
• means, responsive to said determining, for mapping said at least one token representing a field that is present in the message to a first character of a character string and mapping said at least one token representing a field that is absent from the message to a second character of the character string;
• and
• means for replacing the one or more fields present in the message with the character string to obtain a compressed message.

A message compressor for compressing a message to obtain a compressed message suitable for transmission via a data communication network, said message compressor comprising:

• means for replacing fields in the message with tokens;
• means for re-ordering at least two header fields in the message;
• and
• means for, after said re-ordering, combining at least two of said tokens into a character string to obtain a compressed message, wherein the means for combining includes means for combining tokens representing header fields into the character string according to both which headers are present and which headers are absent from the message.
