Abstract
A computer based system and method for distributing a global shaper rate implemented across multiple traffic processing devices. A controller distributes credits according to the demand (amount of traffic, or offered load) of each device, in such a way to achieve global targets, including the shaper rate, strict prioritization of traffic, WFQ weights and fairness between cloned channels, iteratively updated as changes occur in the quantity and makeup of the traffic across the devices.
