Measurement data

This repository contains measurement data from my master thesis "Catching the train - performance evaluation of a wireless SDN".

• Videos, documenting the tests are available at https://www.youtube.com/channel/UCOrOHTunRA2dtMWBWdDsdwQ
• The implementation is published at: https://git.fslab.de/jluehr_ext/trainmesh

This repository is structured as follows:

• The data directory contains the raw data of all measurements.
• The missing_console contains preliminary results, which are not taken into accounts due to problems in the measurement process
• plot contains scripts for generating the plots
• rssicat has data from the RSSI-Survey
• systems include configuration files and dumps from relevant systems in the testbed
• table_dumps contain OpenFlow tables dumped in the experiment.

The main directory includes additional scripts (e.g. cat_i) for parsing and monitoring data during the measurement.

Structure of a data-subdirectory

Each subdirectory contains data from different hosts. The directory itself contains data from the test / SDN controller. This includes:

• iperf.log - Segments received using iperf3
• tcpdump.log - Trace of all data sent to the controller
• app.log / app.err - Output of the SDN application process
• ryu.log - SDN-Controller output ryu.

The sub-subdirectories front and rear contain output from the front and rear radio respectively. This includes

• local_agent.log / .err Output from the local-agenet on mqtt-messages / switching
• Continuous dumps from /proc/net/wireless having RSSI values and error counts
• iw event -t Log from the radios

The sub-subdirectory 192.168.24.32 contains the log of the trainside core router.

• ping.log lists all request / response data for ping experiments
