摘要： A cable modem communicates the timing of the arrival of certain packets (such as TCP ACK packets) to a cable modem termination system. This timing feature is useful in methods for increasing the throughput in the downstream direction by eliminating TCP ACKs backing up at a cable modem. In particular, a cable modem termination system implementing an unsolicited bandwidth grant service in which unsolicited grants of bandwidth are sent by the cable modem termination system to the cable modem. The grants of bandwidth are timed to arrive at the cable modem simultaneous with or shortly after the arrival of the TCP ACK from an end station connected to the cable modem. Several methods of calculating or predicting when the unsolicited grants should be sent to the cable modem are described. The method is also applicable to other types of packets, such as voice packets from a end station implementing a Voice over Internet Protocol (VoIP) application.

摘要： A head-end in a data-over-cable system transmits a multicast message in a downstream channel to all the cable modems in a particular MAC layer. The message includes an address field that contains an upstream channel multicast MAC address that identifies a particular channel, and is used to send a multicast message for which only cable modems transmitting in the upstream direction in that channel are to respond. When the message is received by the cable modems, the cable modems compare the upstream channel multicast MAC address with addresses stored in a memory. If a match is found, indicating that the cable modem happens to transmit in the upstream direction in the particular channel, it processes the message. If no match is found, the message is discarded. The upstream channel multicast MAC address helps noise avoidance or redundancy problems associated with a particular channel to be quickly remedied, and avoids the head-end from having to send out a large number of unicast messages in order to communicate with all the modems sharing a given upstream channel.

摘要： System and method for providing a multi-frequency upstream transmission channel to a network device. When a headend network entity generates an upstream channel descriptor message, the descriptor message includes at least two upstream frequencies available for upstream transmission, and a frequency hopping descriptor with a frequency-hopping pattern associated with the available frequencies for determining an upstream frequency for upstream transmission. The headend provides a timing reference for determining upstream transmission periods on the frequencies available on the network device. When the headend receives upstream transmission on one of the available upstream frequencies, the headend network entity determines frequency distortions. If the distortions exceed a threshold level, the headend may send a new upstream channel descriptor message that excludes the upstream frequency associated with the high frequency distortions, add a new upstream frequency, or defines a new frequency-hopping pattern.

摘要： Methods for improved cable modem ranging in a data-over-cable system. One method includes receiving a value that characterizes how equipment in the network is configured. Using this characteristic value, a cable modem may estimate loss in its upstream path from a measurement of a downstream signal and thereby estimate its initial transmit level during ranging. Launching at a proper initial transmit level may ensure that range request messages arrive at the cable modem termination system with sufficient strength to be detected and hence ameliorate ranging. Another method collects difference between these estimated initial transmit levels and the final transmit levels that succeeded in evoking a response from the cable modem termination system. The collected differences are analyzed and the result of the analysis is passed to cable modems to adjust their estimated initial transmit levels. These methods may shorten a cable modem's time for ranging and may decrease collisions on the upstream path when many cable modems try to range simultaneously.

摘要： A cable installation system for use by a cable installer may include a plurality of cable dispensers having different lengths of cable. In particular, each cable dispenser may also have a non-numeric, length-identifying marking associated therewith corresponding to the length of cable. Furthermore, the system may also include a cable dispenser indicator device for use by the installer to determine a distance between first and second locations, such as a cable tap and a subscriber interface. The cable dispenser indicator device may also provide an indication to the installer of the non-numeric, length-identifying marking corresponding to the determined distance so that the cable installer can select the corresponding cable dispenser from the plurality thereof. By way of example, the non-numeric, length-identifying markings may include a series of different colors and/or graphics for respective length ranges.
