Which two are characteristics of jitter buffers? (Choose two.) 

Answer options:

A. Jitter 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.
B. Jitter buffers are used to change asynchronous packet arrivals into a synchronous stream by turning variable network delays into constant delays at the sending systems.
C. The role of the jitter buffer is to balance the delay and the probability of interrupted playout due to late packets.
D. The role of the jitter buffer is to queue late packets and reorder out-of-order packets.
E. Jitter buffers are used to change asynchronous packet arrivals into a synchronous stream by queuing packets into constant delays at the sending systems.

AC

Jitter buffers are used to remove the effects of jitter so that asynchronous packet arrivals are changed to a synchronous stream. The jitter buffer trades off between delay and the probability of interrupted playout because of late packets (discard). References: http://www.appneta.com/blog/jitter-voip/
