-QUIC/UDP/IP with vpp_echo
-^^^^^^^^^^^^^^^^^^^^^^^^^
-
-`vpp_echo performance testing tool <https://wiki.fd.io/view/VPP/HostStack#External_Echo_Server.2FClient_.28vpp_echo.29>`_
-is a bespoke performance test application which utilizes the 'native
-HostStack APIs' to verify performance and correct handling of
-connection/stream events with uni-directional and bi-directional
-streams of data.
-
-Because iperf3 does not support the QUIC transport protocol, vpp_echo
-is used for measuring the maximum attainable goodput of the VPP Host
-Stack connection utilizing the QUIC transport protocol across two
-instances of VPP running on separate DUT nodes. The QUIC transport
-protocol supports multiple streams per connection and test cases
-utilize different combinations of QUIC connections and number of
-streams per connection.
-
-The test configuration is as follows:
-
-::
-
- DUT1 Network DUT2
- [ vpp_echo-client -> VPP1 ]=======[ VPP2 -> vpp_echo-server]
- N-streams/connection
-
-where,
-
-1. vpp_echo server attaches to VPP2 and LISTENs on VPP2:TCP port 1234.
-2. vpp_echo client creates one or more connections to VPP1 and opens
- one or more stream per connection to VPP2:TCP port 1234.
-3. vpp_echo client transmits a uni-directional stream as fast as the
- VPP Host Stack allows to the vpp_echo server for the test duration.
-4. At the end of the test the vpp_echo client emits the goodput
- measurements for all streams and the sum of all streams.
-
-Test cases include
-
-1. 1 QUIC Connection with 1 Stream
-2. 1 QUIC connection with 10 Streams
-3. 10 QUIC connetions with 1 Stream
-4. 10 QUIC connections with 10 Streams
-
-with stream sizes to provide reasonable test durations. The VPP Host
-Stack QUIC transport is configured to utilize the picotls encryption
-library. In the future, tests utilizing addtional encryption
-algorithms will be added.
