-# UDP/IP with iperf3
-
-[iperf3 goodput measurement tool](https://github.com/esnet/iperf)
-is used for measuring the maximum attainable goodput of the VPP Host
-Stack connection across two instances of VPP running on separate DUT
-nodes. iperf3 is a popular open source tool for active measurements
-of the maximum achievable goodput on IP networks.
-
-Because iperf3 utilizes the POSIX socket interface APIs, the current
-test configuration utilizes the LD_PRELOAD mechanism in the linux
-kernel to connect iperf3 to the VPP Host Stack using the VPP
-Communications Library (VCL) LD_PRELOAD library (libvcl_ldpreload.so).
-
-In the future, a forked version of iperf3 which has been modified to
-directly use the VCL application APIs may be added to determine the
-difference in performance of 'VCL Native' applications versus utilizing
-LD_PRELOAD which inherently has more overhead and other limitations.
-
-The test configuration is as follows:
-
-           DUT1              Network               DUT2
-    [ iperf3-client -> VPP1 ]=======[ VPP2 -> iperf3-server]
-
-where,
-
-1. iperf3 server attaches to VPP2 and LISTENs on VPP2:UDP port 5201.
-2. iperf3 client attaches to VPP1 and transmits one or more streams
-   of packets to VPP2:UDP port 5201.
-3. iperf3 client transmits a uni-directional stream as fast as the
-   VPP Host Stack allows to the iperf3 server for the test duration.
-4. At the end of the test the iperf3 client emits the goodput
-   measurements for all streams and the sum of all streams.
-
-Test cases include 1 and 10 Streams with a 20 second test duration
-with the VPP Host Stack using the UDP transport layer..
-
-Note: iperf3 is single threaded, so it is expected that the 10 stream
-test shows little or no performance improvement due to
-multi-thread/multi-core execution.
