Claim:
1. A switch configured to calculate latency variation in a distributed manner, comprising: first and second input ports, a first output port, and a local latency variation calculator; the first and second input ports are configured to receive packets of first and second streaming sessions from second and third output ports of second and third switches, respectively; the first output port is configured to send the packets of the first and second streaming sessions to a third input port of a fourth switch; the local latency variation calculator is configured to receive first and second calculated local latency variations of the first and second streaming sessions at the second and third output ports, respectively; and the local latency variation calculator is further configured to calculate a third calculated local latency variation of the first streaming session at the first output port, based on the first and second calculated local latency variations.
