dgt_net02 – The Transport Layer

Module Title: dgt_net02 – The Transport Layer

Overview:
The “dgt_net02 – The Transport Layer” module is designed to provide an in-depth understanding of the transport layer within networking. This crucial layer ensures reliable data transfer between systems over a network, serving as a key component of the OSI model and TCP/IP stack. The module targets students, IT professionals, and anyone interested in advancing their knowledge in computer networks.

module Objectives:
– To understand the role and functions of the transport layer within the networking architecture.
– To explore protocols such as Transmission Control Protocol TCP and User Datagram Protocol UDP, analyzing their mechanisms, advantages, and disadvantages.
– To gain hands-on experience with transport layer operations through practical exercises and simulations.
– To learn about error detection and correction techniques, flow control, and congestion management at the transport layer.
– To understand how the transport layer interacts with other layers in both OSI model and TCP/IP protocols.

Key Topics:
1. Introduction to Transport Layer Concepts:
– Overview of the OSI Model and its Layers
– Role of the Transport Layer in Networking

  1. Transport Layer Protocols:
  2. In-depth study of TCP:
    • Connection-oriented services
    • Reliable data transfer, flow control, and error recovery mechanisms
    • Congestion control algorithms such as slow start, congestion avoidance, fast retransmit, and fast recovery

  3. Exploration of UDP:

    • Connectionless communication
    • Use cases for applications where speed is more critical than reliability

  4. Mechanisms and Techniques:

  5. Segmentation and Reassembly
  6. Error Detection and Correction e.g., checksums
  7. Flow Control Mechanisms e.g., sliding window, credit-based flow control

  8. Congestion Management Strategies

  9. Security Considerations:

  10. Understanding the vulnerabilities at the transport layer

  11. Techniques for securing data transmission e.g., TLS/SSL

  12. Interactions with Other Layers:

  13. Relationship between Transport Layer and Network Layer

  14. Integration of applications with Transport Layer Protocols

  15. Practical Applications and Case Studies:

  16. Real-world applications using TCP and UDP
  17. Analysis of case studies highlighting the importance of transport layer protocols in various industries.

module Format:
– Interactive lectures supplemented by video tutorials.
– Lab sessions for hands-on experience with network simulation tools.
– Group discussions and collaborative projects to reinforce learning.
– Quizzes and assessments to evaluate understanding and retention.

Target Audience:
This module is ideal for students majoring in computer science, IT professionals seeking certification or career advancement, and anyone interested in networking fundamentals and transport layer protocols.

By the end of this module, participants will have a solid foundation in transport layer concepts and be equipped with practical skills to implement and troubleshoot TCP/IP networks effectively.
The students can push their exercises to the Academy DevOps & SRE GIT project. For this module, create a folder with your username as its name in the following subfolder: https://github.com/Garanti-Del-Talento/gdt_academy
