ABSTRACT:
Provided is a method for classifying packets in a cable modem termination system (CMTS) supporting a channel bonding mode. The method includes the steps of: extracting a destination Media Access Control (MAC) address of a received data packet; acquiring a MAC address of a cable modem receiving the data packet, and memory address information of a cable modem Classifier Identifier (CLID) corresponding to the MAC address of the cable modem, from a first classification table corresponding to the destination address; extracting the CLID information present in the memory address; extracting a classifier pattern corresponding to the extracted cable modem CLID information; bonding the MAC address of the cable modem and the classifier pattern to generate a result pattern; extracting a memory address including downstream service flow information from a second classification table corresponding to the result pattern; extracting the downstream service flow information corresponding to the memory address; and generating an output packet corresponding to the downstream service flow information and the data packet.
