Abstract: PURPOSE: A fair packet scheduler through weighted fair queuing(WFQ) emulation in a high-speed integrated service network and method thereof, is provided to maintain a counting complexity of a system virtual time with zero/one while securing a delay bound and a fair index in a WFQ standard. The fair packet scheduler provides a fair and optimum delay bound, when deciding packet transmission orders based on a traffic contract with a network by connection of each packet entering an asynchronous transfer mode(ATM) exchange or a router. CONSTITUTION: An input traffic processor(210) utilizes a system virtual time maintained and managed in a node whenever a new packet arrives at the node to calculate a time stamp, and adds the time stamp to a header of arrived packets. Queue blocks(220-1/220-n) temporarily store the packets processed in the input traffic processor(210) and make the stored packets waited. A start packet processor(230) selects a packet having a smaller time stamp value among the standby head packets. A server(250) transmits the packet selected in the start packet processor(230) according to arrival orders to a link. And the start packet processor(230) updates the system virtual time before a start time of a new service, after the service for the packets in the server(250) is ended.
