Transport layer
Section outline
-
Week 1 introduces the Internet transport layer and its core protocols. It explores the basic principles of the transport layer, focusing on its role in end-to-end communication. You'll learn to identify its key components and describe the main features of the User Data Protocol (UDP). The module also introduces the essential mechanisms of Automatic repeat request (ARQ) protocols for ensuring reliable transmission. The videos are followed by a final test to verify your understanding of the concepts presented.

Week 2 is dedicated to the study of the Transport Control Protocol (TCP), one of the Internet’s foundational protocols. It delves into the structure and functionalities of TCP, focusing on its reliability features. You’ll learn to describe the protocol’s key characteristics and identify how flow control, error control, and congestion control mechanisms operate within it. The videos are followed by a final test to verify your understanding of the concepts presented.
