Quality of service criterion hierarchical system for data transmission network

We consider methodology for hierarchical multicriterion estimation of variants of data transmission network evolvement and operating. The paper is focused on system of aims and subtests for solution of rational choice problems of topology and network parameters during analysis, design and modification. Based on data transmission network operation we constructed three-level hierarchical system of indicators and numerical criterions of network performance and quality of service. Proposed system provides to take into account different approaches, which are defined by different decision making subjects. These approaches are concerned on formulating of operation aims and development of network structure. They are focused on creation of interactive tools for automate design systems, control and operation supporting of telecommunication networks during their lifetime.
