A NEW VoIP ADAPTIVE PLAYOUT ALGORITHM
A novel playout algorithm for VoIP applications is presented. The playout times of voice packets are calculated using adaptive estimation of network delays. In contrast to previous solutions, the weighting factor that controls the estimation process is dynamically adjusted according to the observed delay variations. This results in higher-quality estimates of network delays. With this algorithm...

متن کاملAn Adaptive Jitter Buffer Playout Algorithm for Enhanced VoIP Performance
The QoS standard of a VoIP session degrades if its stringent time requirements are not met. Low end-to-end delay of the voice packets and low packet loss must be maintained. Jitter between voice packets must also be within tolerable limits. Jitter hampers voice quality and makes the VoIP call uncomfortable to the user. Very often, buffers are used to store the received packets for a short time ...
متن کاملSupporting SIP Personal Mobility for VoIP Services
SIP is promising for VoIP signaling to support personal mobility. In this paper, we introduce and compare single registration (SR) and multiple registration (MR) for personal mobility. The SR scheme can not support personal mobility without user’s assistance. In contrast, the MR scheme supports personal mobility inherently using sequential search or pure parallel search. Sequential search may s...
متن کاملInteractivity-aware playout adaptation
Adaptive Playout is a solution in IP-based communication clients to compensate network issues using a dynamic receiver buffer. Whereas small buffers provoke loss artefacts due to delayed packets, large buffers result in high delay and loss of interactivity. Existing Voice over IP clients balance the trade-off between low delay and loss artefacts based on empirical values. Most often the degree ...
