摘要:
A method and apparatus of classifying downstream service flows for a cable modem is provided. A method of classifying downstream service flows, the method including: classifying a service flow based on a Quality of Service (QoS) using a destination address of an inputted packet; composing an internal header including corresponding service flow information based on the classifying of the service flow; and adding the internal header to the inputted packet.

A method and apparatus of controlling a downstream service flow is provided. A method of controlling a downstream service flow, the method including: receiving a control request with respect to a service flow; generating classifier information for identifying a Quality of Service (QoS) classification standard of the service flow for which a generation request is performed, and registering the generated classifier information in a table when the control request is the generation request for the service flow; registering a pattern mask corresponding to the classifier information in the table; and composing the table for searching for downstream service flow information of a downstream input packet using the classifier information and the pattern mask.

Provided is an apparatus and method for providing a video service flow using a dual scheduler for a headend cable modem in a Hybrid Fiber Coax (HFC) network. The apparatus may include: a service flow processing unit to determine whether a packet corresponds to a registered video service flow, when the packet is received; and at least one channel transmitter to schedule a packet corresponding to the registered video service flow and a packet not corresponding to the registered video service flow so that a transmission rate of the registered video service flow is guaranteed, and to thereby transmit the packets.
摘要:
A method and apparatus of processing a multicast service flow for a headend cable modem is provided.The method of processing the multicast service flow includes: classifying an inputted multicast packet by a session; composing an internal header including multicast service flow information allocated to the classified session; and outputting an internal multicast packet including the internal header.

Provided is an IP network-based headend system. The headend system may obtain service flow information pre-registered in a subscriber modem device, may transmit, to a service supply server connected based on an IP network, the pre-registered service flow information and the network protocol packet, may determine a data reception route determined by the service supply server, may receive, from the service supply server, a video data stream to perform data processing, may receive data processed video data stream, and may transmit the data processed video data stream to the subscriber modem device based on the pre-registered service flow information.
