A jitter buffer is a common method for managing jitter in networks. It temporarily stores arriving packets in order to minimize delay variations. If packets arrive too early, they are delayed in the buffer, and if they arrive too late, they are discarded or marked as lost. This can smooth out the packet flow, reducing the impact of jitter on the application. However, the use of jitter buffers can introduce additional delay, so they must be used judiciously to avoid causing other performance issues.
