Service invocation admission control algorithm for multi-domain IP environments

One approach to solve the end to end (E2E) quality of services (QoS) problem of multimedia services delivery over multi-domain IP heterogeneous network infrastructures in a scaleable manner is the establishment of long term QoS enabled aggregated pipes. To allow dynamism, the actual service invocation of these pipes can be made as a separate action from the pipes subscription. This paper proposes a service invocation admission control algorithm that can be applied to aggregated IP pipes taking into account new service requests and the actual utilization of the domain resources of the subscribed pipes. 2007 Elsevier B.V.
