Methods of Teaching / Learning
The learning and teaching strategy is designed to achieve the following aims.
Students taking this module will have a detailed knowledge of modern telecommunications and packet networks; they can dimension networks, as well as and analysis and evaluate the network performance and quality of service (QoS).
Learning and teaching methods include the following.
Lectures: Total 30 hours of lectures (3 per week) plus problem-solving and revision sessions.
Labs: In 2x 3-hour Lab session, Software simulation tool for switch and route will be installed in the Lab or students’ own computers. The students will learn the simulation tool, and are given a task to design and simulate a typical enterprise network.
Assignment(s): Students will submit report based on the design and simulation, covering the following aspects:
Produce a design of a typical enterprise networks.
Set up connections of switches and routers.
Configure individual switch and routers.
Generate traffic loads for certain applications and services.
Capture the network packets
Analyses the performance and QoS provided by the network
Draw a conclusion.
The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes. The written examination will assess the knowledge and assimilation of terminology, concepts and theory of telecommunications and packet networks, as well as the ability to analyse problems.
The Assignment will assess the ability to use the analytical skills to evaluate network performance and QoS.
Thus, the summative assessment for this module consists of:
2 hours closed book written examination (80%)
1 coursework report (20%)
Formative assessment and feedback
For the module, students will receive formative assessment/feedback in the following ways.
During lectures, by question and answer sessions
During tutorials/tutorial classes
By means of unassessed tutorial problem sheets (with answers/model solutions)
Support will be provided to students on their Lab session and use of simulation tool.
