JAIN (JAVA APIs FOR INTEGRATED NETWORKS)
A set of APIs focused on emerging network protocols and architectures driven by convergence of traditional telecommunication and IP networks. Defined by the Java Community Process.

JITTER
The result of a temporary change in latency of packet delivery over a communication channel. Jitter will cause packets to arrive to their destination in a fluctuating manner.

JITTER BUFFER
A portion of memory specifically allocated to storing IP packets awaiting transmission, or to storing received IP packets. The buffer facilitates flow control by capturing IP packets and then transmitting packets as “playback” using speeds and rates of delay that the destination device can handle, without causing packet loss through overloading.

JITTER BUFFER MANAGEMENT
Jitter buffer management represents the trade-off between a larger buffer and increased rates of jitter.
