Redes2425 – Data Link Layer Protocol Implementation

Overview

This project focuses on the implementation of a Data Link Layer protocol designed to enable reliable data communication over computer networks. The protocol is built around the Stop-and-Wait ARQ (Automatic Repeat reQuest) mechanism, ensuring frame delivery with flow control and error handling.

Features

• 🧱 Frame Encapsulation – Structures data into well-defined frames for transmission.
• 🔁 Stop-and-Wait Protocol – Implements a simple ARQ method ensuring reliable frame delivery.
• ⚠️ Error Detection & Handling – Uses checksums or parity to identify transmission errors.
• 📶 Flow Control – Prevents sender overflow using acknowledgment (ACK) and retransmission logic.
• 🔒 Medium Access Control (MAC) – Coordinates access to the shared transmission medium.

Technical Details

• Layer: Data Link Layer (Layer 2, OSI Model)
• Protocol Type: Stop-and-Wait ARQ
• Language: C / C++ (or specify)
• Error Control: Frame acknowledgment and retransmission
• Frame Format: Custom header with control bits and checksum

Use Case

This protocol is ideal for educational purposes and low-speed or noise-prone communication channels where simplicity and reliability are key.
