Abstract

See full text

A hierarchical congestion management system improves the performance of traffic through a communications system. In one embodiment of the invention, a first subset of thresholds is configured so as to guarantee the passage of a certain high-priority or other selected communications traffic. Further, a second subset of thresholds is configured to control interference among independent flows of traffic that are competing to pass through the system. As a result of these configurations, traffic flows that cause congestion at the output are isolated to prevent dropping other traffic, and high-priority traffic is ensured passage.
