Abstract: A system and method is provided for supporting data transfer protocols that extend beyond standard protocols used in conventional data over cable systems. A subscriber station in accordance with the invention determines, during registration, whether a base station with which it communicates is capable of supporting an extended protocol, and if it is, transfers data to the base station in accordance with the extended protocol. Additionally, a base station in accordance with the invention is notified during registration whether or not a subscriber station supports an extended protocol and stores this information. When a request for transmission opportunity is subsequently received from the subscriber station, the base station accesses the stored information to determine if the cable modem supports the extended protocol.

Abstract: A method and computer program product for providing RTP suppression across a DOCSIS network. An index number and a set of rules are sent to a receiver. The index number indicates the type of header suppression technique (i.e., RTP header suppression) to be performed, and the set of rules define how to recreate the RTP packets on the receiving end. At least one complete RTP packet is transmitted upstream for enabling a receiver to learn the RTP header. Subsequent RTP packets are transmitted upstream for reconstruction at the receiving end. The subsequent RTP packets are comprised of delta values representing fields that dynamically change from packet to packet in an RTP header.

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.
