An approach for controlling bandwidth allocations for a switching system wi th transmission constraints is disclosed. A scheduler (603) within a switching system generates bandwidth metrics for a destination site. A traffic control processing logic (613) receives the bandwidth metrics. The tragic control processing logic (613) includes a utilization module (615) that determines utilization associated with the destination site based upon the received bandwidth metrics, and an error calculation module (617) that computes the difference between the determined utilization and a target utilization. A gain and filtering module (619), which is also a part of the traffic control processing logic (613), computes a correction value based upon the difference between the determined utilization and the target utilization, in which the correction value being associated with the destination site. Further, the traffic contr ol processing logic (613) includes an adder (621) that outputs a control value based upon a reference control value and the correction value. A bandwidth control processor (611) assigns bandwidth allocation based upon the control value. |
