Abstract: PURPOSE: A method for allocating just resources to network users and an apparatus thereof are provided to dynamically bandwidth on the basis of a bandwidth reduction ratio dynamically determined. CONSTITUTION: A flow information collecting unit collects information about flow(S301). The flow information collecting unit groups the collected flow information(S302). A detection unit compares a ratio value between an F/B value and an F/P value with a predetermined threshold value. In case the ratio value exceeds the predetermined threshold value, a bandwidth control unit calculates a recommended bandwidth(S304,S305). The bandwidth control unit controls the bandwidth of the grouped flow(S306).

The plurality of line card processors receive the data packet from the external node, or transmit the data packet to the external node. The switch fabric switches the data packet between the plurality of line card processors and between the line card processor and the application processor according to control of the application processor. The Ethernet switch switches the control packet between the application processor and the plurality of line card processors.

Abstract: A packet forwarding method in a subscriber access network connecting device and an apparatus thereof are provided to extract an IP(Internet Protocol) head of a packet one time only, and to process QoS(Quality of Service) profile information acquisition, forwarding information acquisition, and virtual queue number acquisition in parallel by using multiple engines, thereby improving data processing performance. A receiving buffer(31) receives inputted packets. A head extractor(32) extracts a head from the buffer(31). The first to third forwarding engines(33-35) take charge of packet classification, forwarding information acquisition, and packet queueing information acquisition, then simultaneously acquire classification, forwarding information, and queueing information for predetermined packets if head information of the packets is delivered, and configure meta data of the packets. A meta data storage(36) stores metal data structures for each packet configured by the acquired information. A transmission buffer(37) stores the packets processed into the data, before the packets are outputted to a switch fabric. A scheduler(38) determines a transmission sequence of the stored packets by using the meta data.
