Abstract :
Speech quality, with cell losses in an ATM network, has been evaluated previously using random cell loss rates. However, it has been shown that cell loss behavior for speech transmission in ATM is more appropriately described by the burst model due to the burstiness properties of the aggregate voice cell arrival process. A mathematical model, called the burst model for cell loss behavior in an ATM network, has been developed. The burst model predicts cell loss behavior very accurately as link capacity increases. According to the burst model, it has been calculated that SNRseg decreases by 1.5 dB at the link load of 98% for the STS-3C link
