The VCL echo server/client test applications, vcl_test_server and vcl_test_client, are bespoke performance test applications which supports all of VPP's HostStack transport layer protocols:
- tcp
- udp
- quic
- tls
They utilize VPPComsLibrary (VCL), as opposed to 'raw session layer' (see here), APIs to verify performance and correct handling of connection/stream events with uni-directional and bi-directional streams of data.
They can be found in the build tree at
$ ./build-root/build-vpp[_debug]-native/vpp/bin/vcl_test_[server/client]
and as of VPP 20.01 they are included in the main vpp debian package (e.g. vpp_20.01-release-amd64.deb)
Start vpp1 and attach the server application:
$ ./build-root/build-vpp_debug-native/vpp/bin/vpp_test_server -p tcp 1234
Then start vpp2 and attach the client:
<code>$ ./build-root/build-vpp_debug-native/vpp/bin/vpp_test_client client -U -p tcp <vpp1_ip> 1234
The current command line options for vcl_test_server are:
vcl_test_server [OPTIONS] <port>
OPTIONS
-h Print this message and exit.
-6 Use IPv6
-w <num> Number of workers
-p <PROTO> Use <PROTO> transport layer
-D Use UDP transport layer
-L Use TLS transport layer
The current command line options for vcl_test_client are:
vcl_test_client [OPTIONS] <ipaddr> <port>
OPTIONS
-h Print this message and exit.
-6 Use IPv6
-c Print test config before test.
-w <dir> Write test results to <dir>.
-X Exit after running test.
-p <proto> Use <proto> transport layer
-D Use UDP transport layer
-L Use TLS transport layer
-E Run Echo test.
-N <num-writes> Test Cfg: number of writes.
-R <rxbuf-size> Test Cfg: rx buffer size.
-T <txbuf-size> Test Cfg: tx buffer size.
-U Run Uni-directional test.
-B Run Bi-directional test.
-V Verbose mode.
-I <N> Use N sessions.
-s <N> Use N sessions.
-q <n> QUIC : use N Ssessions on top of n Qsessions
