Abstract
An ATM switch, and method for operating such a switch, are disclosed. In one embodiment, the switch detects ABR VCs that are likely bottlenecked elsewhere in their network path, allowing it to calculate a fair share of available bandwidth for those VCs that are bottlenecked locally. In another embodiment, the switch combines this fair share value with a per-VC queue congestion prediction to arrive at an explicit rate for that VC. The congestion prediction is based on a VC's queue occupancy and upon the VC's rate and rate trend, allowing fast response times and aggressive explicit rate values. The present invention allows switches to maximize throughput while maintaining small queue sizes.
