Abstract

Enhancing performance in a multicasting system. Flow rates in a multicasting system are monitored as system characteristics change. The multicasting system is operated based on a first mapping between data flows and multicasting groups. Data is disseminated by way of the mapping to subscribers to one or more of the data flows. The flow rate thresholds of satisfied flows are decreased to minimize the difference between the flow rate thresholds and respective target transmission rates of the satisfied flows, as the system's feasible data transmission workload is maintained with respect to subscriber reception rate capacities. The flow rate thresholds of unsatisfied flows are increased to minimize the difference between the flow rate threshold and respective target transmission rates for the unsatisfied flows and to limit occurrences of data transmission delays or losses, as the system's feasible data transmission workload is maintained with respect to subscriber reception rate capacities.
