Abstract :
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 for original Erlang B model based on characteristics of codec and network link in use. At last we prove the model outcome and applicability with simulation results using NS2 software.
