Abstract

Service Level Agreement (SLA) management can be adapted to support the end-to-end QoS for service users in Beyond 3 Generation (B3G) networks. In B3G networks, SLA provides multiple service classes on access networks so that service classes should be managed to assure the service satis- faction for users. In this paper, we propose a dynamic QoS management scheme by IP traffic class controlling based on SLA in B3G networks. To manage dynamic traffic service, we consider Differentiated services (Diffserv) mecha-nism for the resource management by SLA. An IP service traffic class on SLA can be dynamically changed by Diffserv traffic management to support dyna-mic end-to-end QoS. Simulation results show that the proposed scheme has higher performance in comparison with non-dynamic management scheme.
