29. Network structure: introduction Telecommunications network structure determines significant part of the most important parameters of infocommunication systems. Due to this reason, problems of telecommunications network structure analysis and synthesis constitute self-dependent direction among researches conducted in the interest of all participants of infocommunication market. Certainly, the network structure analysis and synthesis can’t be completely separated from other processes of infocommunication system creation and development. Nevertheless, for the study of complex object or process it is necessary to discriminate a number of independent problems in it. The tasks of telecommunications network structure analysis and synthesis are united by the set of final goals, methodological approach, and mathematical apparatus. Final goal of these tasks solving is to build an efficient infocommunication system that will provide execution of specified functions and is able to develop. The word "efficient" indicates the fact that network structure is close to the optimal one. Methodological approach to analysis and synthesis of telecommunications network structure can be considered as integrated problem. Mathematical methods used for solution of such problem are identical.
