Hi Ilias/Akashi-san,
So after the call earlier this week Mike asked me to write-up a EPIC for the measurement work. I think this covers the deployments we want to measure but any feedback is welcome. The Xen documentation talks rather euphemistically about Open vSwitch but I don't know if that is just the management name for using the same network routing internals as the other ePPF ones.
Anyway any thoughts?
Ilias/Akashi,
Any comments before I put this into JIRA cards?
1) Do we learn any lessons from the past study like: https://connect.linaro.org/resources/bkk19/bkk19-504/ "BKK19-504 XDP Offload for OPC UA" either on test methods/scenario or performance results?
2) You expect that the measurement will be done on the network between a guest VM and a outer (physical) machine (or sensor/camera?). What about vm-vm performance?
3) If the network between vm and a outside machine does matter, we should also evaluate the case where multiple guests are running and accessing the same (physical) NIC (at least, virtually).
4) Should we take TSN switch on the system into consideration?
