Abstract: A packet scheduling system and a method thereof are provided to divide input traffic into real time traffic and non real time traffic and assign differential output time and priorities to keep an attribute of traffic and effectively process only abnormal flow to adjust bandwidth of input traffic. An input scheduler(20) produces one or more flows by using a packet inputted through an input port(10). The traffic is divided into a real time traffic and a non real time traffic. The input scheduler determines output time and priority according to an attribute of traffic including each flow and a packet included in each flow. An output scheduler(30) transmits each packet to the outside based on the output time and priority of the packet determined in the input scheduler through an output port(50).

Abstract: A packet-based circuit band control method is provided to control the flow of received packet data by measuring the accumulation band and effective band of each subscriber and then comparing the measured accumulation band and effective band with the current band. The accumulation band time and effective band time are measured through a received packet(S205). A flow is registered through the flow state table search(S215). If the received packet is a controlled target packet, the state of the flow including the received packet is confirmed(S230). If the flow is registered, the operation of the flow is temporarily released and a flow state table is updated(S235). The effective band time is calculated through the received packet processing time(S250).
