Approximate method of calculation of node characteristics in telecommunication network with repetitive transmissions

A model of packet commutation nodewith repetitive transmissions for two schemes of buffermemory distributions — fully accessible and fully shared — is considered. The approximate method of calculation of stream intensity and probabilities of node blocking is proposed. The necessity and sufficiency conditions for existence and unicity of solution of equation were derived for streams in node when operating regime became established, and the convergence of iteration method for solving proposed equation was proved.
