Network performance QoS estimation

This paper deals with network performance simulation and quality of Triple-play services in IP networks. Based on our designed analytical model, the application has been created by means of which it is possible to predict qualitative parameters for QoS in IP networks, with regard to policies applied for packet processing by routers and with regard to the level of total network utilization. The contribution of this paper lies in designing a new model capable of predicting the quality of Triple-play services respecting queuing policy and transmission speed of interfaces on routers in packet networks.
