DEVELOPMENT OF FOUR - LEVEL MODEL SYSTEM OF SDH / SONET NETWORK MA N AGEMENT

It has been conducted the analysis of performance process of optical commun i cation systems of synchronous SDH / SONET networ k, which is connected to the system control, its testing and collection of statistical data on the passage of the signal in the event of ordinary, extraordinary or emergency situations, as well as the manag e ment or administrative management of the system. The i m plementation of management tasks at the physical, logical, informational and administrative levels is associated with the development of SDH / SONET math e matical model of the network management system. In this regard, the problem of development syste m of SDH / SONET 4 - level network management model has been posed and solved in this work. In connection with this, it has been carried out a structural analysis of buil d ing management systems and developed a structural model of the control system based on the model of colle c tive control units, a mathematical model of functioning with seepage theory, the reliability model of functioning over time. The developed system of four - level SDH / SONET network management model provides a fundamental limit a tion on the performance of structural reliability based on critical probabilities, the value of which is determined by the princ i ples of building the control systems of optical data transmission systems.
