Throughout this book, emphasis has been placed on the direct relationship between the traffic-carrying efficiency and the cost of a telecommunications system or network. The traffic-handling performance of every system and net work is limited by its configuration, the concepts employed to transmit, switch and route traffic, and the design of the manufactured products which implement those concepts. To achieve a given standard of performance, therefore, requires careful attention to system choice and network design. The situation can arise where the required performance standard is beyond the technical capability of a proposed system or network solution, giving rise to the need either to find an alternative solution or to accept a lower standard of performance. Traffic-hand ling performance can be estimated by a network designer with sufficient accuracy for most dimensioning/sizing purposes, but there will be an occasional need for a detailed evaluation of system/network performance by a specialist performance engineer. Telecommunications managers should, therefore, have an understanding of what can be achieved in this field.
