Impact of Network Control System Performance on Efficiency of Large Corporate Network

Abstract

Complex and heterogeneous network with different physical principles of data exchange is learned. The impact of efficiency and correct choice of parameters of network control system on successful operation of network information system as object of control is researched. It was shown that common criterion of network system efficiency is the functional of its parameters and state, which may be described by stochastic Markov processes. The evaluations of number of possible states of network as complex information system are given. The states of full performance, slow degradation of parameters, and full failure of system are singed. The discrete process of transition of system from one state to another one is described by Markov chain.
