Title: Packet switching apparatus adapted to control allowed transmission rate in packet switching network, and method of controlling allowed transmission rate

Abstract: A packet switching apparatus is disclosed which is adapted to determine and control an allowed transmission rate of a transmitting terminal in a packet switching network. The packet switching apparatus comprises a rate discriminator to monitor an interval of packet reception for each of connections, judge, based on the interval of packet reception, whether the transmitting terminal having sent the packet is in pause of transmission and determine a first allowed transmission rate for the transmitting terminal correspondingly to a result of the judgment, an ER calculator to calculate, based on a predetermined algorithm, a second allowed transmission rate for the transmitting terminal, and an ER setter to select one of the first allowed transmission rate determined by the rate discriminator and second allowed transmission rate calculated by the ER calculator, whichever is smaller, and write it into a packet returned to the transmitting terminal.
