Evaluation of lightweight preemption algorithms for UPnP QoS Architecture

Preemption is a common approach for QoS provisioning in multiservice and multiuser networks where the network resources are exhausted. This paper focuses on the analysis of the lightweight algorithms for the UPnP QoS Architecture where the decision about preemption is made by computation power limited home gateway. Based on the data obtained, the comparison of the proposed algorithms shows that the performance of simple methods can give satisfying rejection and preemption rates.
