Apparatus and method for controlling an Ethernet switch's bandwidth

摘要

A bandwidth control apparatus controls a bandwidth of a port in a network switch. An apparatus is provided that includes a random variable generating section to generate a random variable corresponding to a predetermined ratio associated with a bandwidth decrease. A timer generates an expire signal and a bandwidth control section generates a transmit enable signal to a port responsive to the random variable and the expire signal. And a port controller transmits data frames responsive to the transmit enable signal and to generate a transmit request signal to the bandwidth control section.
