Module description

Digital Convergence is the bringing together of communications, information, media and transactions from multiple service providers, across multiple network infrastructures and delivery to any device. This should be done in a way that offers a consistent service experience regardless of a user's location. This module will begin with the definition and description of converged networks and services and identify current and emerging services and network architectures. The introduction will also include an overview of the key next-generation network architectures that are being deployed today.

In order to understand the design of any network, it is important to understand the service characteristics in terms of customer usage patterns and traffic behaviour; these fundamentally determine the desired Service Level Agreements (SLAs) and ultimately the network and service architectures. Ensuring satisfactory user experience for multiple services will be addressed in detail by means of various Quality-of-Service (QoS) mechanisms. When a user is mobile and traversing multiple access network technologies and administrative domains, ensuring a seamless service is a demanding task that requires both the convergence of different types of wireless networks and the convergence of fixed and mobile networks.

An overview of the problems and proposed solutions will be described from the perspective of a wireless Internet Service Provider (ISP) and a cellular mobile operator. The course will conclude with a clean-slate future Internet architecture called Information Centric Networking (ICN) that can go beyond the current IP networks.

Module aims

The aim of this module is to understand the design of any network and the service characteristics in terms of customer usage patterns and traffic behaviour, describing the service level agreements (SLAs) to ensure satisfactory user experience.

Module learning outcomes

On completion of the course, the student is expected to be able to:

1. Understand and describe a converged network architecture and its implications.
2. Define a network specification for converged services (e.g. voice, video and data).
3. Understand the design process of a converged network.
4. Describe the methods of mobility support in heterogeneous access networks.
5. Discuss methods of implementing QoS strategies and service management.
6. Discuss the difference between information-centric networks and IP-based networks.

Disclaimer: The University makes every effort to ensure that this information on its Module Directory is accurate and up-to-date. Exceptionally it can be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements, industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules. The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
