ABSTRACT:
A method and apparatus for providing backpressure flow control to traffic flows of a data communications system are provided. Embodiments of the invention selectively apply a measure of flow control to traffic flows responsive to a level of congestion at a packet processor of the system. These embodiments advantageously provide flexibility in the application of flow control to specific traffic flows in accordance with one or more of characteristics of those traffic flows.
