Description

INACTIVE - The aim of the module is to introduce the students to higher network layer-related concepts and in particular to develop their understanding of transport and application level protocols. Students will be introduced to the requirements of modern data transport for real-time applications. Students will be introduced to the concept of network quality of service (QoS) Students will analyse the implications of QoS on data transport and how this affects the users.

Learning Outcomes

1. Describe network Quality of Service metrics
2. Analyse the impact of QoS metrics on traffic delivery for different traffic types.
3. Describe network protocols at the application and transport layers and assess their appropriateness for transport of various traffic types.
4. Compare different network implementations and analyse their benefits and deficiencies in delivering different types of data
5. List relevant standards and standards bodies and identify QoS parameter values using standards.
6. write basic network applications.

Reassessment Requirement Type
Resit arrangements are explained by the following categories: Resit category 1: A resit is available for both* components of the module. Resit category 2: No resit is available for a 100% continuous assessment module. Resit category 3: No resit is available for the continuous assessment component where there is a continuous assessment and examination element.
* ‘Both’ is used in the context of the module having a Continuous Assessment/Examination split; where the module is 100% continuous assessment, there will also be a resit of the assessment
This module is category 1
