Module summary

The teaching and assessment methods shown below will be kept under review during 2020-21. In particular, if conditions allow for alternative formats of delivery, we may amend the timetable and schedule appropriate classes in addition to (or in place of) the Online Learning Workshops. For Semester 2 (from January 2021), we anticipate that this will be most likely, in which case online teaching will be substituted for traditional face-to-face teaching methods, including lectures and practical classes. ‘Independent online learning’ will involve watching pre-recorded lecture material or screen-casts, engaging in learning activities such as online worked examples or remote/virtual laboratory work, etc. Students will be expected to fully engage with all of these activities. The time commitment for independent online learning, and also the frequency and duration of Online Learning Workshops, are approximate and intended as a guide only. Further details will be confirmed when the module commences.

Objectives

To provide students with a knowledge and understanding of data communications networks, their use in a range of applications, and network security measures.

Learning outcomes
On completion of this module students should be able to:

1. Apply appropriate models to the analysis of communication systems, including a variety of network architectures and protocols.
2. Demonstrate a knowledge and understanding of the principles behind the organisation and operation of communications networks.
3. Apply appropriate models to the analysis of communication systems, including a variety of network architectures and protocols.
4. Apply mathematical methods and modelling techniques to the analysis of communications networks and understand basic mechanisms for network flow control via the study of local area networks.
5. Appreciate the importance of routing and congestion control, eg in relation to wide area and global networks.
6. Appreciate the security issues associated with communications networks and understand the principles of network security protection.
7. Understand high level protocols and more advanced systems with current and next generation technology.
8. Contribute to strategic planning, systems implementation and operation of data communications and sensor networks.

Syllabus

Topics may include, but are not limited to:

The ISO/OSI 7-layer model, and TCP/IP structure
The use of layering, protocols, interfaces etc
Data types, data communications, and networking terminology
Data link control, particularly error control methods such as detection and correction, (parity checks, checksumming, CRC, - ARQ, sequence numbers), flow control, address resolution and wireless LANs
The network layer, IP datagrams, fragmentation and reassembly, IP addresses, routing principles (link-state, distance vector), Internet routing and QoS support
TCP/IP provision and IPv6 (and IPv6 and IPv4 interoperability) and mobility
Basics of network security

Private study

Students are expected to use private study time to consolidate the material covered in lectures, to undertake preparatory work for examples classes/laboratory classes and to prepare for summative assessments.

Opportunities for Formative Feedback

Feedback will be mainly provided through the examples classes.
