| Popis: | Quality of Service (QoS) and resource management in Next Generation Networks (NGN) is provided by a particular architecture called RACF (Resource and Admission Control Function) which has been introduced by ITU. In this paper, we analyze the impact of different resource control schemes in RACF architecture on Call Set-up Delay (CSD). The approach taken is, initially, to introduce the RACF architecture and its main elements and functionalities. Following this, we present two QoS signaling call flows for two resource control schemes and examine them using a queuing model. The simulation results show different performance of these two schemes under different network traffic conditions. Using these results, we have some criteria for selecting the better resource control scheme appropriate to traffic changes. |
