Patent ID: 7489628

Claim:
A system for monitoring a communication traffic transfer rate control mechanism in accordance with which transfer rate control is applied to a first communication traffic management device to control a rate of transfer of communication traffic from the first communication traffic management device to a second communication traffic management device, the system comprising: a monitor configured to compile a communication traffic storage history by determining respective amounts of communication traffic stored in at least one communication traffic queue of at least the second communication traffic management device at each of a plurality of monitor times, and to determine, based on the communication traffic storage history, whether the transfer rate control mechanism achieves target communication traffic behavior at the second communication traffic management device; an output configured to provide an indication of the determined amounts of communication traffic; and a control parameter adjustment system, coupled to the monitor, to adjust a control parameter of the transfer rate control mechanism responsive to a determination by the monitor that the transfer rate control mechanism does not achieve the target communication traffic behavior at the second communication traffic management device, wherein the control parameter adjusted by the control parameter adjustment system responsive to the determination comprises at least one of: a threshold based upon which the transfer rate control mechanism controls the rate of transfer of communication traffic between the communication traffic management devices, a threshold multiplier used to adjust a threshold based upon which the transfer rate control mechanism controls the rate of transfer of communication traffic between the communication traffic management devices, a degree to which the transfer rate control mechanism reduces or increases the rate of transfer of communication traffic between the communication traffic management devices, and a frequency at which the transfer rate control mechanism performs a transfer rate control operation to determine whether transfer rate control is to be applied to the first communication traffic management device.
