Network traffic simulation is a process used in telecommunications engineering to measure the efficiency of a communications network. ==Overview== Telecommunications systems are complex real-world systems, containing many different components which interact, in complex interrelationships.〔Flood, J.E. ''Telecommunications Switching, Traffic and Networks'', Chapter 4: Telecommunications Traffic, New York: Prentice-Hall, 1998.〕 The analysis of such systems can become extremely difficult: modelling techniques tend to analyse each component rather than the relationships between components.〔〔Penttinen A., ''Chapter 9 – Simulation'', Lecture Notes: S-38.145 - Introduction to Teletraffic Theory, Helsinki University of Technology, Fall 1999.〕 Simulation is an approach which can be used to model large, complex stochastic systems for forecasting or performance measurement purposes.〔〔〔Kennedy I. G., ''Traffic Simulation'', School of Electrical and Information Engineering, University of the Witwatersrand, 2003.〕 It is the most common quantitative modelling technique used.〔 The selection of simulation as a modelling tool is usually because it is less restrictive. Other modelling techniques may impose material mathematical restrictions on the process, and also require multiple intrinsic assumptions to be made.〔 Network traffic simulation usually follows the following four steps:〔〔 *Modelling the system as a dynamic stochastic (i.e. random) process *Generation of the realizations of this stochastic process *Measurement of Simulation data *Analysis of output data 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Network traffic simulation」の詳細全文を読む スポンサード リンク
