A SIMPLE ADAPTIVE JITTER BUFFERING ALGORITHM FOR NETWORK NODES

摘要

A method of dynamically adjusting the buffer delay of an adaptive jitter buffer of a network node receiving packets of a media stream from a packet switched network. The method comprises inserting packets arriving to the network node into the jitter buffer and executing a jitter buffering procedure once every Trepin, wherein Trepin is equal to the jitter buffer play-out interval. Executing the jitter buffer procedure involves updating a jitter protection time, Tjit, 1wherein Tjit defines a current target value for the maximum buffering delay, on the basis of the variation of the number of pending packets, N in the jitter buffer.
