- ДокументQuality control of functioning of telecommunications systems(ХНУРЭ, 2013) Andrushko, D. V.; Volotka, V. S.; Skibin, V. P.Quality control of functioning of telecommunication systems (TCS) is considered, based on the results of the statistical analysis of the spectral matrix of residual detunes obtained at the optimal state estimation of the different elements in the network. The recommendations are given on the method of forming the matrix of residual detunes. (50) The proposed method of diagnosing the quality of telecommunications systems solved in the space of signals on the principle of "learning with a teacher" has a higher reliability than the method solved in the parameter space. The residual detune, obtained due to result of best estimation system as a result of a "supervised learning", has the most complete information about the state of the system deviation from the desired characteristics. Therefore, the method based on the use of the statistical characteristics of the sequence of residual detunes (the matrix of residual detunes) to diagnose the quality of functioning of TCS is the most informative. The upper confidence limit of the spectral norm of the matrix normalized for residual detunes can be used as a threshold function for detecting disorders (disorder) in the state of the system. In order to localize the causes of disorder it may be recommend to use of individual assessment of filters for each object of diagnosis.
- ДокументThe Model and the Method of Two-Level Routing in Mpls(Thi_Qar University Journal for Engineering Sciences, 2012) Лемешко, О. В.; Andrushko, D. V.; Hailan, A. H.In the article mathematical model for routing in the MPLS network is proposed. Also method of two-level routing on the basis of goal coordination principle in the MPLS network is offered. The method is used to increase the scalability of flow-based routing strategies.I
