Abstract :
Network parameters for the effective handling of bursty voice samples are investigated by computer simulations. Two packetization methods, the maximum block method and the average block method, are examined. The latter has a higher transmission efficiency. The packet loss probabilities of two voice synchronization methods, the blind-delay method and the absolute timing method, are evaluated for various average transmission delays and various standard deviations of transmission delay. For both synchronization methods, the delay variation should be small to decrease packet loss probability. The values of delay and delay variation that guarantee the maximum tolerable packet loss probability and the maximum tolerable end-to-end delay are calculated
