This module provides an introduction to the basics of packet switching technologies as used in the internet. Emphasis is placed on core Internet protocols such as IP and TCP.

Subjects covered include:

  • network access technologies
  • design of network protocols using layering
  • local area networks
  • TCP/IP routing and switching
  • and congestion control.

This module introduces the internet with a top-down view: the accent is on layer abstractions and the associated protocols (and how to program with them). Particular attention is paid to questions of network security.

Pre-requisite

Further Programming

Module learning outcomes

  • Have a critical understanding of the purpose and workings of IP and TCP.
  • Design and implement simple communication protocols based on the Internet model of communication outside the context in which they were first studied.
  • Understand and use sockets in programming.
  • Evaluate critically questions of basic networking security.
