I need to use a tool to monitor the entire Mininet flow and to display the flow flowing through each switch port, but it seems that this tool only supports OvS now. And probably because the P4 and OvS bridges are different, the tool is not adapted to P4.
I would like to know what is the way to modify the P4 bridge to make it compatible with OvS, or a good tool to monitor the entire Mininet flow and cut it to fit well with P4.
I thought about the in-band telemetry approach, but the in-band telemetry manual is too complicated, and I would like to know what is an easy way to get started with in-band telemetry, and I would be grateful for some tutorials.
Thank you very much for your answer!
For some reasons, I can’t use ONOS, but write a simple controller using Mininet’s API. Can I complete in-band telemetry without using ONOS?
You can deploy the INT in you P4 program, morover you have to extend it with tables,actions,etc for providing and handling the INT. The link that I shared with you provide an overall overview but here you can find an example of INT that could also help you to undestand the documentations avaiable on P4.org onos/int.p4 at master · opennetworkinglab/onos · GitHub
