A router using clock synchronizer is invented for distributed traffic control for QoS (quality of service) guarantee of real-time traffic in packet switching network such as the Internet. The real-time traffic includes voice and video and should be transmitted in a certain time limit. Otherwise, the quality of the traffic is affected and the information is no longer useful. Packet scheduler in the router transmits packets within the time limit. However, the packet scheduler is not fast enough compared to the link speed and the size of the router. This invention uses a plurality of processors and almost identical time for each processor. The traffic control algorithm can be performed independently by each processor. Thus, the processing speed of the entire router can be raised
