Method and device for consolidation of preferential resource constraints
First Claim
Patent Images
1. A device for providing consolidation of preferential resource quality of service constraints specified by a source user and a destination user in a communication network, comprising:
- A) a first quality of service translator, first QOS translator, being operably coupled to receive preferential resource constraints input from the source user, and a second quality of service translator, second QOS translator, being operably coupled to receive preferential resource constraints input from the destination user, wherein the quality of service translators are utilized for translating input quality of service requirements, for each of the source user and the destination user, into a requested resource constraint set and an acceptable resource constraint set,B) a quality of service consolidator, operably coupled to the first quality of service translator and the second quality of service translator, for consolidating the requested and acceptable resource constraint sets of the source user with the requested and acceptable resource constraint set of the destination user in accordance with a predetermined resource constraint merge scheme to provide appropriate resource constraints for path selection and connection establishment,C) a routing function unit, operably coupled to the quality of service consolidator, for selecting an acceptable path for connection establishment between the source user and the destination user, andD) a network resource allocator, operably coupled to the routing function unit, for allocating resources along the selected acceptable path for connection establishment that supports information transfer between the source user and the destination user.

Abstract
A novel resource constraint merge scheme combines the requested and acceptable resource constraint sets for an efficient solution to the problem of consolidating preferential resource constraints. This solution is particularly useful in consolidation of preferential resource constraints in ATM cell relay networks, especially LANs and WANs.

6. A method for providing consolidation of preferential resource quality of service constraints specified by a source user and a destination user in a communication network, comprising the steps of:
-
A) translating, by a first quality of service translator, first QOS translator, receiving preferential resource constraints input from the source user and a second quality of service translator, second QOS translator, receiving preferential resource constraints input from the destination user, the preferential resource constraints for each of the source user and the destination user into a requested resource constraint set and an acceptable resource constraint set, B) consolidating, by a quality of service consolidator, the requested and acceptable resource constraint sets of the source user with the requested and acceptable resource constraint sets of the destination user in accordance with a predetermined resource constraint merge scheme to provide a consistent set of consolidated resource constraints for path selection and connection establishment, C) using a routing function unit to determine an acceptable path subject to the set of consolidated resource constraints, and D) allocating, by a network resource allocator, resources along the selected acceptable path for connection establishment that supports information transfer between the source user and the destination user. - View Dependent Claims (7, 8, 9, 10)
