Abstract: A method and computer program product for recognizing and optimizing the transmission of TCP/IP style traffic across a DOCSIS network. According to the method of the present invention, a full TCP protocol packet is initially transmitted across a DOCSIS network to be learned by the CMTS. Redundant fields in the TCP protocol packet are entirely suppressed when subsequent TCP protocol packets are transmitted across the DOCSIS network. Non-redundant fields in the TCP protocol packet are delta-encoded using a delta-encoded value when subsequent TCP protocol packets are transmitted. The delta-encoded values represent the change in value of the current TCP packet from the previous TCP packet for a non-redundant field. This enables the CMTS to provide an exact reconstruction of all subsequently transmitted compressed TCP protocol packets.

Abstract: A cable modem system and method is provided for the transfer and processing of data in accordance with specialized data transfer protocols while utilizing conventional cable modem termination system (CMTS) equipment. A cable modem system in accordance with the invention includes a cable modem that provides for the modification of data packets in accordance with one or more proprietary protocols and the addressing of the modified data packets to a CMTS. The CMTS is adapted to reconstruct the data packets.

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.

Abstract: A cable modem system and method is provided for the transfer and processing of data in accordance with specialized data transfer protocols while utilizing conventional cable modem termination system (CMTS) equipment. A cable modem system in accordance with the invention includes a cable modem that provides for the modification of data packets in accordance with a proprietary protocol and the addressing of the modified data packets to a headend server. The headend server is adapted to reconstruct the data packets for transmission to other local cable modems or to a packet-switched network. In additional embodiments, the CMTS itself rather than a headend server operates to reconstruct the data packets.

Abstract: A two way communication system is adapted for compatible inter-operation of a plurality of devices operating in accordance with a plurality of protocols. The communication system includes a first group of one or more remote devices that interface with a local host in accordance with a first protocol and a second group of one or more remote devices that interface wit the local host in accordance with a second protocol. The local host includes a protocol processor that identifies transmissions from the first and second groups of remote devices and routes transmissions from the first group of remote devices to a first processor operating in accordance with the first protocol and also routes transmissions from the second group of remote devices to a second processor operating in accordance with the second protocol.
