Master Thesis Project: Model Based Testing for Programmable Data Planes

Järfälla, Sweden
Closing date: 15 December 2022

Your future challenge

With Software Defined Networking (SDN) and programmable data planes it is possible to program the networking function all the way down to the silicon performing the switching of data packets. However, with programmability comes the risk of introducing bugs in the software. To mitigate this, testing can be used to identify the bugs. But the number of states in the data plane configuration together with number of combinations of network protocol fields in data packets makes testing an arduous task.

This master thesis project will study how Model Based Testing can be applied to a programmable data plane. Included in the project are the following steps:

  • Identification of strategies for reducing the number of combinations of tests.
  • Propose a model for the behavior of a data plane function.
  • Select a framework for test automation and implement a prototype of the proposed model.
  • The results will be presented in a written report. 

The details of the project will be determined during the first week of the project where the student will write a specification and time plan for the project.

Your profile

This project is suitable for a master student in computer science, electrical engineering, engineering physics or other relevant education. Excellent programming skills in one or more high level programming languages as well as shell scripting. Analytical abilities are also required for this project. Furthermore, the student should be structured and able to work independently.
