Abstract:
1. A packet relaying method comprising: a first step of coloring an inputted packet based on a predetermined peak bandwidth of a data bit number per unit time for every flow and a packet length of the inputted packet; a second step of coloring an inputted packet based on a predetermined peak bandwidth of a packet number per unit time for every flow and a packet number of the inputted packet; and a third step of determining a color of the inputted packet with a higher priority being given to a color of packet to be discarded, within the colors obtained by colorings at the first and the second steps, wherein the data bit number is a value increased by the peak bandwidth from the data bit number at a packet input time and the packet number is a value increased by the peak bandwidth from the packet number at a packet input time; when the data bit number is smaller than the packet length of the inputted packet at the first step, the inputted packet is colored in red as the color of packet to be discarded, while otherwise the inputted packet is colored in blue, and when the packet number is smaller than the packet number of the inputted packet at the second step, the inputted packet is colored in red, while otherwise the inputted packet is colored in blue.
