— The core-stateless service architecture alleviates the scalability problems of the integrated service framework while maintaining its guaranteed service semantics. The admission control methods proposed to support core-stateless guaranteed services have significant drawbacks. We propose a scalable and robust distributed admission control architecture to support corestateless guaranteed services. Our architecture maintains high network utilization while ensuring that resources are not overallocated. In our architecture, admission control is performed at the ingress edge routers of a request on an edge-to-edge path basis. A token-passing mechanism is used as the resource management framework. The token helps in dynamic and fair division of bandwidth and allows completely distributed resource allocation on a link unless it is close to saturation. The edge routers co-operate to provide fault tolerance effectively acting as a resilient overlay network. Our admission control framework c...
