The paper presents an approach to packet loss probability estimation in modern VoIP networks. Our proposal is based on simple Erlang B model that is widely used for classic telecommunication networks dimensioning. We analyze its potential applicability to modern convergent IP networks. We introduce a procedure to determine proper values of input variables(More)
The paper proposes a method for upper bound estimation of packet loss in VoIP networks. We analyze simple Erlang B model that is used for classic telecommunication networks dimensioning and its possible applicability to modern convergent IP networks. We propose a method to calculate proper input variables for the original Erlang B model based on(More)
The paper analyses packet loss probabilities in network elements of VoIP networks. It utilizes statistical properties of classical telecommunication networks to derive proper characteristics of aggregated VoIP packet flow and to define mathematical model of network element queue. Finally model results are compared with simulation results for various traffic(More)
