  • Modified upstream channel descriptor messages for DOCSIS-based broadband communication systems
    Publication number: 20040017830
    Abstract: A method, apparatus and computer program product for generating and processing upstream channel descriptor (UCD) messages in a DOCSIS-based broadband communications system, such as a DOCSIS-based two-way satellite communications system, is provided. A satellite modem termination system (SMTS) generates a UCD message that includes one or more standard parameters pertaining to an upstream channel of the two-way satellite communications system, wherein the one or more standard parameters are defined in accordance with the DOCSIS protocol, and one or more satellite application-specific parameters pertaining to the upstream channel, wherein the one or more satellite application specific parameters are not provided for by the DOCSIS protocol. The UCD message is transmitted to a satellite modem that extracts both the standard and satellite application-specific parameters for use in managing communication over the upstream channel.

  • Modified range requests enabling bandwidth requests and state of health reporting
    Publication number: 20040006771
    Abstract: A modified ranging request in a broadband communications system. The modified ranging request includes a header, a management message header attached to the header, a management message payload attached to the management message header, and a CRC attached to the management message payload. The management message header enables bandwidth requests to be made by subscriber equipment without contention. The management message header also includes state of health information on the status of a downstream transmission for enabling a central location to determine how to assign subscribers to queues in an adaptive modulation scheme.

  • Explicit congestion notification for DOCSIS based broadband communication systems
    Publication number: 20030199248
    Abstract: Satellite communications are carried out using the Data Over Cable Interface Specification (DOCSIS). Satellite modems are notified of upstream channel congestion by inserting a congestion notification message in a medium access protocol (MAP) message for the upstream channel. Specifically, the congestion notification message is inserted in an unused field of the MAP message, such as the explicit congestion notification (ECN) field. The MAP message can also carry other characteristics of the upstream channel, including priority threshold, multicast access burst availability, and available bandwidth.
