Resource and admission control function (RACF) is the main part of resource management architecture in next generation networks (NGN). In this paper we analyze the effect of different resource control schemes in RACF architecture on some network performance parameters and show that a dynamic policy for scheme selection will outperform the static one. The dynamic policy results in better resource utilization for Best Effort traffic while providing the required resource for QoS-guaranteed traffic. Likewise, we present some suggestions about service control functions (SCF) and RACF responsibilities so that NGN layers independence will be maintained more than before. This led us to a bit alteration in DIAMETER protocol used between RACF and SCF.
