Abstract: A router using distributed processing for FIB look-up and fair queuing algorithm is invented. 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. FIB look-up and switching are performed by different processors to reduce the processing time. The traffic control algorithm can be performed independently by each processor. Thus, the processing speed of the entire router can be raised.
