Find out the Phenomenon that is typical for IP-telephony – Jitter

Another phenomenon that is typical for IP-telephony is jitter, or, otherwise, the random delay in the distribution of the packet.

Jitter is determined by three factors:

  • Limited bandwidth or improper operation of active network devices
  • High signal propagation delay
  • Thermal noise

The most commonly used method of combating jitter is a jitter buffer that stores a certain number of packets.

Typically, the dynamic buffer length adjustment is provided throughout the lifetime of the connection. Heuristic algorithms are used to select the best length. Continue reading
