Quality of Service Routing

The device for providing consolidation of preferential resource quality of service constraints specified by a source user and adestination user in a communication network has two quality of service translators receiving preferential resource constraintsinput from the source and destination users respectively. The translators translate input QOS requirements, for each of thesource and destination users, into requested and acceptable resource constraint sets. A QOS consolidator consolidates theresource constraint sets in accordance with a predetermined merge scheme to provide appropriate constraints for pathselection and connection establishment. A routing function unit selects an acceptable path for connection establishmentbetween the source and destination users. A network resource allocator allocates resources along the selected acceptablepath for connection establishment that supports information transfer between the source user and the destination user.Use Advantage Consolidates resource constraints to resolve potential differences in resource performances of end users.Title Terms prefer resource constrain consolidate combination request accept resource constrain set efficiency solution problemconsolidate prefer resource constrain
