Labs and Assignments


Assignments:

  • Assignment 1 is now online!

    Due: Thursday, 23 October 2014, 17:00.

  • Assignment 2 is now online!

    Due: Friday, 14 November 2014, 11:00.

  • Assignment 3 is a class test

    Date: 4 December 2014, 10am, Hold Lab.

    You will be asked 10 out of the 30 questions from this file (specific numbers will be different).
    The purpose of this test is to deepen your understanding of the network and link layers. The test partly assesses the following learning outcomes:

    • (1) Understand the basic theoretical principles of computer communications networks
    • (4) Understand the organisation of the Internet, and how this organisation relates to the OSI seven layer model
    • (5) Understand the principles of the key protocols that govern the Internet.


Course Aims and Objectives


Course Philosophy:

The Internet is one of mankind's supreme achievements, certainly no less magnificant than the Great Pyramid at Giza or the Apollo Space Program. In this module, we aim to introduce you to the Internet, its architecture and features, and its main protocols. The Internet's protocols enable it to be used for communications between distributed entities, and we will explore some of these in depth, seeking to understand how they work, and why they take the form they do. In doing so, we will draw on Shannon's Theory of Communication, itself an impressive achievement.

This module will provide an important foundation for the third-year module COMP315: Technologies for e-Commerce.

Aims:

To introduce networked computer systems in general, and the Internet in particular:

  • The basic principles that govern their operation,
  • The design and organisation principles of successful computer networks,and
  • The key protocols and technologies that are used in the contemporary Internet.

Learning Outcomes:

Upon completing this module, you should:

  • Understand the basic theoretical principles of computer communications networks (eg the notion of bandwidth, Shannon's law, etc)
  • Understand how the notion of layering and abstraction apply to the design of computer communication networks
  • Understand the structure and function of the OSI/ISO seven layer model of computer networks
  • Understand the organisation of the Internet, and how this organisation relates to the OSI seven layer model
  • Understand the principles of the key protocols that govern the Internet.

While we will mention the OSI/ISO 7-Layer model, most of our focus will be on the simpler North American 5-Layer model.

Course Outline


This table presents the provisional structure for the course, and may change as the semester progresses. We will be following a top-down approach to the protocol stack, as presented in the text book by Kurose and Ross. Most other textbooks, including Tanenbaum, follow a bottom-up approach.

Assessment


  • Coursework: 20 %
    The coursework will consist of 2 programming assignments and a class test.
    Details will follow.

  • Final Exam: 80 %
    The exam will be 2 hours long. Calculators will not be necessary and will not be permitted. the exam consists of two parts:
    • Part A is multiple choice and accounts for 25% of your exam mark.
    • In part B, you will be asked to answer 3 questions out of 4. Each question will be worth 25% of the total marks for the exam. Questions will include a mix of book-work and problem-solving, as in last year's exam paper.
