Abstract

A method, apparatus, and computer program product for dynamic bandwidth allocation in a packet switched network having a ring architecture is disclosed. The method includes monitoring an occurrence of a contention of resources at a participating node and its neighboring nodes on the network. In response to a monitored occurrence of the contention of resources, bandwidth is dynamically allocated according to a fairness algorithm. Dynamically allocating bandwidth resolves contention of resources in a fair manner within given fairness constraints while enabling a prescribed maximum utilization of available bandwidth between the nodes. Lastly, the fairness algorithm generates fairness criteria in response to states that are local to the participating node and states obtained from the neighboring nodes.
