摘要： A method and apparatus for allocating upstream channel resources in a hybrid fiber coaxial (HFC) network are provided. A cable modem termination system (CMTS) previously provides cable modems (CMs) with a plurality of burst profiles through an extended interval usage code (IUC) of an upstream channel descriptor (UCD) message, and allocates resources to CMs by using an optimized burst profile according to an upstream channel status, thereby increasing transmission efficiency of an upstream channel.

摘要： Provided is a method by which a cable modem reports a downstream packet resequencing status to a cable modem termination system, and more particularly, a method of effectively reporting detailed information on a packet resequencing status by further defining a packet resequencing-related event and event-related information in a message reporting the packet resequencing status. The method by which a cable modem reports a resequencing status of the resequenced packets includes the steps of: when a packet resequencing-related event occurs, generating a resequencing status message (CM-STATUS) including packet sequence numbers of packets causing the event; transmitting a band allocation request message for requesting a cable modem termination system to allocate an upstream band for transmission of the resequencing status message; and transmitting the resequencing status message to the cable modem termination system over the upstream band allocated by the band allocation request message. More detailed resequencing status information, such as the remaining capacity of the receive buffer and the resequenced packet map, for more packet resequencing-related events compared to the conventional downstream packet resequencing status reporting method, is transmitted to the CMTS, such that the CMTS copes more flexibly with situations that may occur upon packet resequencing.

摘要： Provided is a method of controlling the flow of downstream traffic in a cable network headend. The method includes the steps of: establishing a session with the modulator; transferring traffic to the modulator over the session; and receiving a buffer-status reporting message reporting the status of a receive buffer from the modulator while transferring the traffic. The method reports buffer-status information of an Edge-Quadrature Amplitude Modulator (E-QAM) to a traffic source, thereby enabling control of the transfer rate of traffic transferred from the traffic source to the E-QAM and preventing overflow/underflow of a receive buffer, packet loss and deterioration of channel use.

摘要： A packet processing apparatus of a cable modem in hybrid fiber coaxial networks for processing a packet received from a cable modem termination system through a plurality of downstream channels is provided. A specific channel number is assigned to each channel and the cable modem termination system transmits downstream service identifier encoding information to the cable modem during an initializing process therebetween. The apparatus includes a plurality of channel receivers, each for generating an interface packet by inserting the channel number of a corresponding channel into the packet received through the corresponding channel; and an input controller that classifies the interface packet into a resequencing packet, which needs to be resequenced, and an ordinary packet, for which resequencing is not necessary, using the downstream service identifier encoding information and stores the resequencing packet and the ordinary packet.
