The article formulates the main tasks of management of information networks and telecommunications services in terms of ensuring their reliable operation. The telecommunication network is considered as a complex system consisting of many components, each of which has its own characteristics of operation during operation. The main functions of the telecommunication network control system are determined: fault detection and network status diagnostics, network device administration, forecasting and elimination of congestion and other possible deviations in network functioning, ensuring coordinated interaction between different types of control systems for providing telecommunication services with specified quality.Methods of analysis and management of networks are essentially a kind of identification methods, i.e. the current assessment of the parameters and condition of complex technical systems. There is a close relationship between identification and diagnostic tasks. The methods for solving these problems largely depend on the class to which the identification object can be assigned. Computer and telecommunication networks belong to the class of distributed systems with delays in signal and control information. Methods of retrospective identification are used to analyze the state of such systems.The influence of delays of signal and control information on the efficiency of search and determination of places of failures, overloads and emergency modes in communication networks is investigated. The results of computer simulation are given. The approach based on regular control of parameters and condition of network nodes taking into account delays of receipt of information on parameters and a condition of a concrete network node and delays of the control information necessary for adjustment of parameters of a network node as control object has found further development.
