Switching between Fixed and Call-Adaptive Playout: A Per-Call Playout Algorithm
Younchan Jung, John William Atwood · IEEE Internet Computing · 2005
Adaptive playout algorithms provide a popular way to calculate voice-over-IP (VoIP) packets' playout delay - the difference between the playout time at the receiver and the packet-generation time at the sender. The authors' proposed per-call adaptive algorithm uses network delays received from the VoIP gatekeeper to switch between fixed and call-adaptive playout. Their approach also reduces loss rates while increasing playout delay only slightly.
