Handling quality requirements of multimedia services and the
expectations of end-users regarding the perceived service quality is
currently a major issue for service providers in order to sustain
service diversity and improve competitiveness. In this context, this
paper presents ongoing work toward a service-oriented architecture for
QoE/QoS evaluation and control, which can be deployed to assist the
provision of multi-constrained services. Considering the users' QoE
perspective and the negotiated service levels, the architecture lays on
per service class online monitoring to assist self-adaptive control of
multimedia flows entering the network. To perform online monitoring, a
distributed and versatile QoS monitoring tool oriented to multiservice
networks is proposed. Preliminary results shows that the presented
control strategy is effective in providing consistent quality
levels to heterogeneous services.
