Hi Macro, I’m running on master branch and latest version.
“make test TEST-test_sctp.py” also works for me. I want to benchmark the performance of sctp, but fifo-size is only 4 in test_sctp.py, so the throughput is only ~2Gbps. If I increase the fifo-size in test_sctp.py, then the test fails. That’s why I want to use CLI commands to test SCTP. I’m not intended to run multiple clients, the reason I set nclients=2 is because test_sctp.py does the same thing, I just want to keep the same. You mean you use the same commands in my last mail, and there is no issue? If yes, then I need to check my setup.

Second, can you run "make test TEST=test_sctp.py" and see if that works for you? It all looks good on my side and on Jenkins. If you are interested in running multiple clients, you can do that by editing test_sctp.py and add "nclients X" (where X can be 2 or more). Again, I have just tested it right now and I cannot see that issue.

And is there any performance report for SCTP? You can have a look at the test for SCTP: 1) test/test_sctp.py 2) src/vnet/session-apps/echo_client.c & echo_server.c The echo_client and echo_server are used by TCP / UDP and SCTP to exercise the networking stack implemented. With regards to the state-machine (I assumed that's what you're asking by "association", "packet transmssion/reception", etc.), the whole of it is gone through when running the tests. If you are interested in seeing/learning how that's implemented I am afraid you need to look into the code tho. With regards to performance: no, there're no reports. However, something can be retrieved by running the test_sctp.py since at the end it prints out how much data has been transferred and how long that took.

If yes what is the configuration for SCTP. Does it support the same features as the linux kernel SCTP ? VPP has an implementation for SCTP. You can look into /src/vnet/sctp folder to see what we currently support in terms of RFC. Any feedback (and contribution) is very much welcome!
