Dimensioning Approaches for an Access Link Assuring Integrated QoS

This paper proposes some model-based alternatives for the solution of dimensioning an access link that conveys a mixture of realtime and elastic traffic. The novel feature of the proposed provisioning approaches is that the bandwidth they provision assures simultaneously packet-level QoS for realtime traffic and flow-level QoS for elastic traffic. This is achieved by appropriately adapting and combining packet-level and flow-level analytical models. Simulation is performed to demonstrate the operation of the proposed approaches.
