Abstract
A process involves controlling an output rate of a network device using rate control logic, and providing a variable bandwidth for the rate control logic and increasing a response time constant of the rate control logic according to an amount of time that an input rate of data to the network device is evaluated by the rate control logic; applying a rate estimate when a determination of the output rate to a predetermined accuracy is unavailable; applying a time rate determined from the difference in two PCR packets otherwise; and applying the time rate determined from the difference in two PCR packets unless the rate estimate shows that an actual rate has changed to an extent that triggers a change in the output rate to the rate estimate.
