Data packet communication system in which data packet transmittal is prioritized with queues having respective assigned priorities and frequency weighted counting of queue wait time

摘要

A packet communication system in accordance with the present invention wherein, when the system receives packets each made up of a predetermined unit data from a plurality of terminals, these packets are arranged to once form a packet queue, the packets in the packet queue are sequentially and selectively transmitted, and the selection of one of the packets of the packet queue to be immediately transmitted is determined through simple operation, whereby high speed processing can be realized and discardable packets in the packet queue can be selectively discarded with high freedom.
