Description including Unit Aims

This unit aims to introduce students to the fundamental design principles of modern networked applications. This is achieved through a study of a number of distributed systems, ranging from classic web-based applications, to machine-to-machine communications, telemetry and the Internet of Things. The unit discusses how different applications have different requirements, for instance regarding performance, scalability and reliability. Through examples of application and transport layer protocols used in today’s internet, the unit provides insight into a range of system architectures and communication paradigms and highlights how different design choices can have an impact on the extent to which an application’s requirements can be met.

Intended Learning Outcomes

On successful completion of this unit, students will be able to:

  1. Identify and describe key performance indicators for contemporary computer networks and distributed applications. Formulate performance requirements for different classes of networked applications.
  2. Describe the main functions performed by the transport layer of the TCP/IP layered model. Describe and compare the various transport layer protocols used in contemporary networks.
  3. Discuss and compare different distributed application architectures. Compare and critically analyse their key characteristics.
  4. List, describe and compare distributed application interaction models.
  5. Compare protocols in terms of their ability to support i) different interaction models and ii) the requirements of different distributed applications.
  6. Select suitable protocols and apply them as part of the design of a distributed application. Justify protocol selection and discuss advantages and disadvantages.
  7. Underline protocol design challenges for networks of severely constrained wireless embedded devices and the Internet of Things. Describe, compare and evaluate protocols used in contemporary IoT networks.

Teaching Information

Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.

Assessment Information

Formative: Online Test 1

Summative: Exam (May/June) (100%)


If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EENGM0009).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
