Compare TCP/IP stack from Zephyr RTOS with LWIP TCP/IP stack from the speed, code size, and features points of view. Both TCP/IP stacks are written in C language. Use i.MX RT, LPC or Kinetis as a main platform for your evaluation. Leverage zperf network traffic generator example already available in Zephyr RTOS and port it to run on FreeRTOS and LWIP as an MCUXpresso SDK application.

Motivation: The aim of this diploma's thesis is to conduct a comprehensive analysis and comparison of two prominent TCP/IP stacks, namely the TCP/IP stack present in Zephyr RTOS and LWIP TCP/IP stack, based on their speed, code size and features. Given the importance of efficient network communication in embedded systems, a thorough evaluation of these stacks will provide valuable insights for choosing the most suitable solution for specific embedded platforms.

Analysis: The analysis phase will involve a detailed study of both Zephyr and LWIP TCP/IP stacks, focusing on their architectural designs, core functionalities, and supported features. Key aspects such as memory management, socket implementation, and protocol support will be examined to identify the strengths and weaknesses of each stack.

Design: During the design phase, criteria for evaluating speed, code size, and features will be established. The design will involve outlining a structured methodology to perform benchmarking tests on the chosen platforms (i.MX RT, LPC or Kinetis). The porting of zperf to use FreeRTOS and LWIP TCP/IP stack will be planned to facilitate performance evaluation. Implementation: Implementation will encompass leveraging the zperf implementation available in Zephyr, which will be also ported to use LWIP TCP/IP stack and run on FreeRTOS instead of Zephyr. Benchmarking scenarios will be devised, and test cases will be set up to measure the speed and efficiency of network communication using both TCP/IP stacks on the selected embedded platforms.
