An Adaptive Playout Buffer Algorithm for VOIP

Rokovoy A.P.

An adaptive playout buffer to overcome jitter in VoIP is proposed. It based on forecasting of the future network state and allows maintaining the jitter buffer at the minimum level at which packets are not discarded by receiver, providing the optimal ratio between the amount of delay introduced by the jitter buffer and the number of discarded packets. The experimental results showed the fundamental possibility of predicting jitter for voice over IP networks.
