PACKET CONGESTION CONTROL METHOD AND PACKET SWITCHING EQUIPMENT

摘要

A packet switching equipment (60) housing therein a plurality of pairs of an input line (301) and an output line (303) is provided with a monitor circuit (223) for monitoring a packet congestion state in the packet switching equipment for each output line. When a packet congestion is detected in association with either one of the output lines, a congestion indicator is added to a packet to be delivered to the output line so as to return the packet as a congestion notice packet to an equipment (50) as the transmission source of the packet; furthermore, the input packet is relayed via the output line to the destination equipment.
