The term traffic-carrying performance, as applied to any telecommunications network, is used to describe how effectively that network is able to transfer information between users. Earlier chapters have shown that traffic-carrying performance is inversely related to the percentage of calls lost and call set-up delay experienced with a circuit-switched telephone network, and to information-transfer delay across all types of data network. Call losses or delays can only be reduced by providing more or, with data, faster circuits and more equipment, at greater expense; thus traffic-carrying performance is also directly related to overall network cost. By matching the traffic-carrying performance of a private telecommunications network as closely as possible to the needs of the business concerned, it is possible to ensure that network costs are no greater than absolutely necessary. This objective can be achieved by designing the network to meet a performance target.
