Abstract
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.
