AGGREGATED RESOURCE RESERVATION FOR DATA FLOWS

摘要

A network node is provided for reserving resources for data flows in a communication network, The node detects a request for resource reservation for a new data flow and computes an admission test count based on a plurality of descriptors of the new data flow and reservation counts, the reservation counts representing reservation functions of a plurality of descriptors of already admitted data flows and specifying resources of admitted data flows. The new data flow is admitted, if the admission test count is smaller than a maximum admission count for the plurality traffic descriptors and the reservation counts are updated based on the descriptors of the new data flow. A plurality of admission formulas may thus be used to maintain aggregated reservation counts for data flows, the number of counts being independent form the number of flows.
