AIMS

This subject provides an introduction to the basic principles, analysis, and design of communication networks. It will cover analytical tools, the layered network architecture, and network protocols.

Analytical tools from queueing, optimisation, control, graph theories will be used to develop an in-depth understanding of basic principles and the role they play in network design. Queueing theory will be emphasised as the primary methodological framework for analysing network delay which is one of the most important performance measures in data networks.

The concepts taught in this subject will allow a better understanding of the Internet as well as emerging communication paradigms such as Machine-to-Machine communication, Internet of Things, smart grid, and social networks.

INDICATIVE CONTENT

Topics to be covered may include:

• Queuing theory: basics, birth-death processes, M/M/x and Markovian queues, networks of queues.
• Optimisation and control methods for routing and flow (congestion) control.
• Basics of graph theory and social network analysis relevant to communication networks.
• Network topologies for core and access networks.
• Voice and circuit-switched networks, packet switching and multiplexing gain.
• The layered network architecture with a focus on physical-layer multiple access (TDM, WDM), link layer protocols and medium access control (MAC), network layer topologies, least-cost routing algorithms and protocols, transport layer protocols and the principles and techniques of practical reliable transport.
• The Internet's network layer including the Internet Protocol (IP), ICMP, and routing protocols including an introduction to BGP and the operation of forwarding tables in routers and shortest prefix routing.
• The Internet's transport layer protocols UDP and TCP, including the flow and congestion control algorithms.
• LAN protocols in particular Ethernet, and configuration protocols DHCP and ARP.
• Sensor networks, Machine-to-Machine communication, Internet of Things, social networks.
• Network performance analysis and planning.

INTENDED LEARNING OUTCOMES (ILO)

Having completed this unit the student should be able to:

1. Quantitatively analyze the performance of simple queueing systems and communication networks;

1. Explain the basic principles of communication network design, the layered architecture and network protocols;

3. Design simple communication networks to achieve performance objectives.
