摘要：
The aim of this study is to develop a method for evaluation of service quality estimations in continuous monitoring system for computer networks. The computer network is considered as dynamic system with service functionality objects. We proposed the composed concept of quality of service evaluation in conditions of continuous monitoring process. It is suggested to reduce the services state estimation to the forming of qualitative estimates of a state and calculating a trend of these estimates values. Practical significance consists in rising of networks controllability and decreasing its exploitation cost by the possibility of the service quality analysis, forecasting its changes, which allows making the appropriate control decision. The method is based on consideration the service as the functional network object describable with the set of service state indexes, which are varying in time. Quality if service is also determined by the set of these indexes and also varies in time. The suggested method allows us to estimate the service by its quality in the current time and by the forecasted quality for the next two times taking in account given values of thresholds. It is also proposed to evaluate service quality indices as quantity on time and prediction estimations. Correctness of the solutions is proved by examples. © 2010 Asian Network for Scientific Information.
