Methods and systems for distributed calculations of latency variation

A network configured to calculate latency variation in a distributed manner, comprising:

• first, second, and third switches comprising first, second, and third output ports, respectively;
• the first and second switches are configured to calculate first and second calculated local latency variations of first and second streaming sessions at the first and second output ports, respectively;
• wherein first and second paths of the first and second streaming sessions are passing through the third output port after passing through the first and second output ports, respectively;
• the third switch is configured to receive the first and second calculated local latency variations from the first and second switches;
• and
• the third switch is further configured to calculate a third calculated local latency variation of the first streaming session at the third output port, based on the first and second calculated local latency variations.

A method for calculating latency variations in a distributed manner, comprising:

• calculating, by first and second switches, first and second local latency variations, of first and second streaming sessions, at first and second output ports of the first and second switches, respectively;
• receiving, by the third switch, the first and second local latency variations;
• wherein a first and second paths of the first and second streaming sessions, respectively, are passing through a third output port of the third switch after passing through the first and second output ports, respectively;
• and
• calculating, by the third switch, a third local latency variation of the first streaming session at the third output port, based on the first and second local latency variations.
