Abstract :
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 characteristics of both codec and network link in use. Finally we verify the model results against simulation results obtained from NS2 software.
