Abstract:
1. A method of reserving resources for data flows in a communication network, said method comprising the steps of: detecting a request for resource reservation for a new data flow including a plurality of descriptors specifying requested resources, wherein the plurality of descriptors are selected from a minimum bandwidth requirement, a mean bandwidth requirement, a maximum time delay for data transmission, a peak data rate, a mean data rate, and a quality of service requirement; computing an admission test count representing overall required resources when the new data flow is admitted, wherein the admission test count is computed based upon the plurality of descriptors of the new data flow and upon reservation counts, wherein each reservation count represents a product function constituted by a product of functions having as variables the plurality of descriptors of the admitted data flows; admitting the new data flow, when the admission test count is smaller than a maximum admission count representing a maximum bandwidth capability of the network; updating the reservation counts to include the descriptors of the new data flow, when the new data flow is admitted; receiving a release instruction for an identified admitted data flow; releasing the identified admitted data flow; and updating each reservation count to remove the corresponding descriptors of the released data flow by dividing the reservation counts by the product function of the descriptors of the released data flow.
