Unit description Unit description
This unit gives an understanding of advanced topics in the design and implementation of computer networks. It provides an in-depth understanding of key protocols of the TCP/IP protocol suite, and its relationship to emerging technologies. This unit allows students to develop knowledge and expertise in key areas such as intra- and inter-domain routing protocols, multicast protocols, different transport protocols, Quality of Service, and multimedia. These concepts are reinforced through tutorials and laboratory sessions. Knowledge gained during the unit builds upon communication protocols; topological designs; wide area and local area networks; wireless/mobile networks; as well as practical hands-on skills on Cisco equipment. It allows students to expand their skill set by exposure to socket programming paradigm enabling them to better understand the design and implementation of protocols. Some of the reasoning tasks that the students complete require focused thinking instead of iteratively modifying and testing a program. It also enhances students' skills in critical thinking and problem solving using challenging assignments.

Delivery and Resources

Week 1: Lectures commence from week 1. Practical sessions commence from week 2. All classes (lecture and practical) are on campus.

Methods of Communication 

We will communicate with you via your university email and through announcements on iLearn. Queries to convenors can either be placed on the iLearn discussion board or sent to the unit convenor via the contact email on iLearn

Lectures

On campus lecture sessions will provide an opportunity for the students to ask questions on the topic of the week and to clarify anything that they might not be sure of. 

Lecture recordings will be made available through Echo360.

Practicals

Practical sessions commence from week 2 and includes problem solving and practical hands on sessions. 

Practical classes give you an opportunity to practice your practical networking skills under the supervision of a demonstrator. Each week you will be given a number of problems to work on; it is important that you keep up with these problems as doing so will help you understand the material in the unit and prepare you for the work in assignments.

Note that while the practical material is structured against the lecture material, you need to keep in mind that there will not always be a one to one mapping between the practical exercises and the lecture topics. This is because you need some practical sessions to get acquainted to new tools and devices thereby limiting the number of practical time slots available to experiment with technologies discussed in some lectures.

There will be one 2 hour long practical session each week starting week 2 and each practical exercise is worth 2 marks. The practical sessions are conducted in a specially-equipped networking laboratory. There is no opportunity to conduct practical work outside the assigned sessions.Weeks 12 and 13 are catchup weeks and provide an opportunity to do any practical exercise/s that were missed over the course of the semester (weeks 2-11).

Quizzes

The Quiz is an in-class test. It is a formative assessment that can be used to measure students’ knowledge and comprehension of unit materials. Quiz Question types may include multiple choice, and true/false type of questions. Quizzes allow for formative assessment feedback on basic conceptual competence and therefore usually span multiple learning outcomes.There will be two quizzes in the following weeks: 5 and 11. The quiz will be based on your previously covered lecture material. For example, week 5 quiz will be based on lectures done in weeks 1-4. Each quiz contributes 10% of the total mark and serves as a feedback mechanism to monitor your progress in the unit.

These quizzes will be auto marked in ilearn. The results will be released on ilearn in a timely manner .

 

Assignments

The assignment is submitted through Turnitin aand students can see Turnitin similarity reports..Results will be released on iLearn in a timely manner, subject to certain acceptable delays such as accommodating special consideration late assessments..

Late Submission

From 1 July 2022, Students enrolled in Session based units with written assessments will have the following late penalty applied. Please see https://students.mq.edu.au/study/assessment-exams/assessments for more information. 

Unless a Special Consideration request has been submitted and approved, a 5% penalty (of the total possible mark of the task) will be applied for each day a written report or presentation assessment is not submitted, up until the 7th day (including weekends).

Grading

Grades

At the end of the semester, you will receive a grade that reflects your achievement in the unit

  • Fail (F): does not provide evidence of attainment of all learning outcomes. There is missing or partial or superficial or faulty understanding and application of the fundamental concepts in the field of study; and incomplete, confusing or lacking communication of ideas in ways that give little attention to the conventions of the discipline.
  • Pass (P): provides sufficient evidence of the achievement of learning outcomes. There is demonstration of understanding and application of fundamental concepts of the field of study; and communication of information and ideas adequately in terms of the conventions of the discipline. The learning attainment is considered satisfactory or adequate or competent or capable in relation to the specified outcomes.
  • Credit (Cr): provides evidence of learning that goes beyond replication of content knowledge or skills relevant to the learning outcomes. There is demonstration of substantial understanding of fundamental concepts in the field of study and the ability to apply these concepts in a variety of contexts; plus communication of ideas fluently and clearly in terms of the conventions of the discipline.
  • Distinction (D): provides evidence of integration and evaluation of critical ideas, principles and theories, distinctive insight and ability in applying relevant skills and concepts in relation to learning outcomes. There is demonstration of frequent originality in defining and analysing issues or problems and providing solutions; and the use of means of communication appropriate to the discipline and the audience.
  • High Distinction (HD): provides consistent evidence of deep and critical understanding in relation to the learning outcomes. There is substantial originality and insight in identifying, generating and communicating competing arguments, perspectives or problem solving approaches; critical evaluation of problems, their solutions and their implications; creativity in application.

In this unit, the final mark will be calculated by combining the marks for all assessment tasks according to the percentage weightings shown in the assessment summary.

Note: There are no hurdles in this unit.

Concretely, in order to pass the unit, you must obtain an overall total mark of 50% or higher.

Students obtaining a higher grade than a pass in this unit will (in addition to the above)
