Cable Modem System And Method For Supporting Packet PDU Compression
First Claim
1. A method for generating a data compression dictionary and utilizing it to enhance communication efficiency in a DOCSIS compliant network, comprising the steps of:
- i. identifying a plurality of frequently occurring data strings transmitted by a plurality of cable modems in the DOCSIS network;
ii. assigning a token to represent each one of the plurality of frequently occurring data strings;
iii. entering each one of the plurality of frequently occurring data strings and each token assigned to represent each one of the plurality of frequently occurring data strings into a lookup table to produce a data compression dictionary; and
iv. transmitting the data compression dictionary to the plurality of cable modems in the DOCSIS network during initialization of each of the plurality of cable modems.

Abstract
A cable modem system and method are provided for using a data compression dictionary to transmit compressed payload data in a DOCSIS network while utilizing conventional cable modem termination system (CMTS) equipment. A cable modem system in accordance with the invention includes a cable modem and a CMTS adapted to send and receive compressed payload data. In one example, the cable modem is adapted to compress PDU payload data using a data compression dictionary and the CMTS is adapted to reconstruct the compressed PDU payload data that is received from the cable modem.
