Definitions

A traffic mix is a modelisation of user behaviour. In telecommunications, user behaviour activities may be described by a number of systems, ranging from simple to complex. For example, for

plain old telephone service Plain old telephone service (POTS), or plain ordinary telephone system, is a retronym for voice-grade telephone service employing analog signal transmission over copper loops. POTS was the standard service offering from telephone companies from 1 ...

(POTS), a sequence of connection requests to an exchange can be modelled by fitting negative exponential distributions to the average time between requests and the average duration of a connection. This in turn can be used to work out the utilisation of the line for the purposes of network planning and dimensioning.

Objectives

Traffic mix has two goals: * Network links dimensioning * Network equipment dimensioning Both these functions are extremely important to network operators. If insufficient capability is deployed at a node (for example, if a

has 1 gigabit/sec of switching capacity and more than this is offered) then the risk of equipment failure increases, and customers experience poor service. However, if the network is overprovisioned the cost in equipment can be high. Most providers therefore seek to maximise the effect of their spending by maintaining an unused overhead capacity for growth, and expanding key nodes to relieve problem areas. Identification of these areas is accomplished by network dimensioning.
