Purpose

This project aims to measuring TCP/UDP protocol performance with Python in Raspberry Pi 4 via Ethernet connection.

• TCP: Transmission Control Protocol
• UDP: User Datagram Protocol

Features

• Both TCP/UDP Client and Server
• Performance Measurement: Latency - Throughput - Reliability

Prerequisites

• Ethernet cable and Modem
• Raspberry Pi 4 (4GB at least)
• SD Card (32GB at least) and reader

Notes

1. I initially tested with C-based implementations but did not achieve effective results.
   Therefore, I focused on Python-based UDP packet transmission.
