Anomalies due to delay and loss in AAL2 packet voice systems performance models and methods of mitigation.

Anomalies due to delay and loss in AAL2 packet voice systems performance models and methods of mitigation.

This paper investigates the packet delay variation and packet loss probabilities to be expected in typical applications of voice trunking using ATM adaptation layer type 2 (AAL2) and the consequences these may have, such as the need for sequence numbers in voice packet headers. Simulations have been...
