Abstract
The present invention discloses a method of controlling bandwidth for a bridge device applied to packets transmitting between the bridge device and a companion chip. The method first calculates the traffic of packets received by the bridge device and adjusts the frequency of a clock signal that is generated by the bridge device. The clock signal is then outputted to the companion chip, and the companion chip adjusts the output bandwidth according to the clock signal. The bridge device will adjust the frequency of the clock signal when the storage ratio of the receiving queue is beyond a predetermined region and the predetermined region can be the region of the storage ratio between 20 and 80 percent. Additionally, the method of the present invention can be applied to the operation of transmitting packet from the bridge device to the companion chip.
