Mathematical model for research of properties of highways of transport networks at use of several classes of service

In this article was made the system of the nonlinear algebraic equations describing streams on branches and units of a network in a stationary mode at address dispatch of packages on a multiservice communication network with several classes of service. The decision of system allows to calculate for each grade of service time of a delay and probability of losses of packages between each pair units of a network, and also streams for branches and units of a network, a delay, probability of blocking and levels of loadings of channels. The example of calculation of characteristics of a highway of a multiservice network is given.
