Admission Control for End-to-End Multimedia Content Delivery with Quality of Service Guarantees

End-to-end quality of service guaranteed delivery for multimedia content is a challenging issue, especially in multi-domain environments and heterogeneous network infrastructures. The approach proposed by the ENTHRONE project to solve the end-to-end quality of service problem in a scalable manner is to establish, and activate when needed, long-term quality of service enabled aggregate pipes over multi-domain environments for the subsequent transport of individual flows from multimedia content providers to multimedia content consumers. Based on this approach, this paper proposes admission control schemes both at the granularity of individual flows and aggregate demands. Through simulations we show the proper joint operation of the schemes, their ability to provide quality of service, resource utilization gains and to minimize service rejection probabilities.
