Hi Macro, I follow test_sctp.py to use following commands in server and client, but client can not connect server with an error printed “echo_client_node_fn:238: stuck clients” as you can see below. Do I miss any command ?
Server: vpp# set int ip address FortyGigabitEthernet18/0/1 192.168.60.73/24 vpp# set int state FortyGigabitEthernet18/0/1 up vpp# set ip arp FortyGigabitEthernet18/0/1 192.168.60.74 3c:fd:fe:c2:12:68 vpp# session enable vpp# app ns add id 0 secret 0 sw_if_index 2 vpp# test echo server appns 0 fifo-size 4 uri sctp://192.168.60.73/1234 Client: vpp# set int ip address FortyGigabitEthernet18/0/0 192.168.60.74/24 vpp# set int state FortyGigabitEthernet18/0/0 up vpp# set ip arp FortyGigabitEthernet18/0/0 192.168.60.73 3c:fd:fe:c2:17:09 vpp# session enable vpp# app ns add id 1 secret 0 sw_if_index 1 vpp# test echo client nclients 2 mbytes 10 appns 1 fifo-size 4 test-bytes syn-timeout 3 uri sctp://192.168.60.73/1234 2 three-way handshakes in 0.00 seconds 4648.53/s Test started at 37.835987 0: echo_client_node_fn:238: stuck clients Timeout with 2 sessions still active... test failed test echo clients: failed: timeout with 2 sessions Best Regards, Chengqiang Yao From: Marco Varlese [mailto:mvarl...@suse.de] Sent: Thursday, November 8, 2018 4:07 PM To: Yao, Chengqiang <chengqiang....@intel.com> Cc: vpp-dev@lists.fd.io Subject: Re: [vpp-dev] #vpp sctp echo test crash Hi Yao, As per test_sctp.py the command is: test echo server appns 0 fifo-size 4 [URI] Where URI is made up as: sctp://IP/PORT Please, take a look at "test/test_sctp.py" to see also the client side of it.

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!
