Abstract :
An investigation is made of voice packet loss behavior at both the destination and internodal links in a packet switched network. The fractional loss and blocking time periods for both are derived using a bivariate Markov model. The numerical results show that blocking due to the delay constraint at the destination can result in long periods of consecutive packet loss, which seriously degrade voice quality. This work indicates that the packets with excessive delay should be discarded at the internodal links, instead of blocked at the destination. The relation between the internodal link buffer size and end-to-end permissible queuing delay is established
