Topic: Jitter?

[valmach]

Assume all packet sizes are the same. You have a switch with 6 populated ports, and the switch service rate is 1 packet every 50us, and the switch is using Fair Queuing. On the first pass only port 1 and 5 transmits a packet. On the second pass all 6 ports transmit a packet.  On the third pass after port 1 transmits it’s packet, how much jitter was introduced between port 1’s second packet and third packet if the normal average inter-packet jitter is 50us for port 1?

Why don't you just do your own homework?

For example: The first packet arrives at 00:00:01 (1–s delay), the second arrives at 00:00:15 (5-s delay), and the third arrives at 00:00:01, it will finish at 00:00:11. However, the next packet has not yet arrived, it arrives 4 s later. This phenomenon is called Jitter.
