I am working on Network Resiliency with SDN for
Industrial CPS. I need to find end-to-end delay with timestamp method by
inserting timestamps into UDP when it enters the first switch and leaves
the last switch. We use linear toplology. We use Ryu+Mininet and
generate UDP traffic with iperf3 May I know how to carry out this task?
You may want to look at PTP Precision Time Protocol IEEE 1588:
https://en.wikipedia.org/wiki/Precision_Time_Protocol
You need to look for nics and switches which can handle the protocol.
That would be the most reliable time stamping capability native to
network operations.
