Enhancements, then you hereby grant the following license: a non-exclusive,

  • Version of iperf3 (or development branch, such as master or
    3.1-STABLE) to which this pull request applies:

  • Issues fixed (if any):

  • Brief description of code changes (suitable for use as a commit message):

Python files were added to run the client application with JSON output logged to a specific file. The Dockerfile was also updated to make clear that the user should expose both TCP and UDP ports (see paragraph below for command to run Docker image).

Running the image with docker run -dp 5201:5201/tcp -dp 5201:5201/udp <image-name> (with the -dp options exposing both TCP and UDP; without this, UDP may be blocked) lets the user run the Python files and successfully generate output.

I've also now added a CSV with the experiment framework. I based the values off the "Scaling iperf3 to 200 Gbps: A Study in Network Tool Scalability" paper you had shared in Slack to try to get values that made sense and were reasonable, but I'm not sure whether they really make sense and are what we're looking for.
