network audit template

Jitter buffers (also known as playout buffers) are used to change asynchronous packet arrivals into a synchronous stream by turning variable network delays into constant delays at the destination end systems. The role of the jitter buffer is to trade off between network audit template and the probability of interrupted playout because of late packets. Late or out-of-order packets are discarded

If the network audit template is set either arbitrarily large or arbitrarily small, it imposes unnecessary constraints on the characteristics of the network. A jitter buffer set too large adds to the end-to-end delay, meaning that less delay budget is available for the network; hence, the network needs to support a tighter delay target than practically necessary. If a jitter buffer is too small to accommodate the network jitter, buffer underflows or overflows can occur. In an underflow, the buffer is empty when the codec needs to play out a sample. In an over-flow, the jitter buffer is already full and another packet arrives; that next packet cannot be enqueued in the jitter buffer. Both jitter buffer underflows and overflows cause voice quality degradation
