Sažetak
An optimisation process implies procedures and actions for decreasing costs and making the system more efficient. This paper proposes a model for simple management and optimisation of VoIP quality of service. The model is proposed in framework of VoIP communication optimisation based on simple measurement information incorporated in agent architecture for VoIP QoS management. The model is based on adapted E-model for packet communication in which MOS values are assigned from objective measurements of QoS parameters. The large set of objective and subjective experimental QoS measurements is performed in order to asses the range of model applicability in operational network. The comparison of the experimental results of MOS values with calculated values of parameter R, as well as the mapping between them, gives a good base for QoS optimisation based on simple real-time measurements. According to agent based architecture the basic operating procedures for VoIP agent management system with assumed optimisation actions are proposed.
