Teletraffic      Engineering & Management

3 days

Network Planning
Examines the methodology of planning for growth and implementing new technology within networks. The planning life cycle is introduced, its component parts are discussed and the importance of communication between all players in the planning process is highlighted.

Network Structures
A review of network types and architecture is conducted to provide a sound base from which to build upon. Technologies utilised in different networks are discussed to give a basic understanding.

Principles of Teletraffic Engineering
From basic principles a knowledge of traffic engineering is developed. The concept of capacity, busy hour, demand, grade of service, congestion and severe overload is examined. Traffic measurement methods are described and traffic analysis processes are examined.

Why, what and how is discussed. Short-term and long-term forecasting methods are examined. Forecast models are described with a discussion of which models are best-suited to which applications. Monitoring of forecast processes is introduced together with an examination of what inputs are required for different forecasts. Number of customers and Traffic forecasts are carried out in examples.

Loss and Queueing Theory
The principles of loss system engineering is examined and Erlang's formulae and applications are discussed. Queueing theory and its applications are also discussed. Practical examples serve to consolidate understanding of the subject.

Drawing upon the knowledge gained in the previous modules dimensioning of switch capacity, transmission capacity, cross-connect, and signalling capacity is discussed and processes are examined. Practical examples serve to consolidate understanding of the subject.

Traffic Management
Principles of traffic management are introduced in this module. The impact of different routing strategies and traffic efficiency is discussed. Planning for traffic management is discussed together with the requirement to be able to measure demand and capacity in the network (real-time) and the need to be able to control traffic demand and traffic flow within the network to protect the network from overload and to enable extra traffic to be carried over lightly used parts during focussed overload conditions.

New Technologies
What traffic engineering principles can be applied to new network technologies and how they may be applied are discussed.
