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