Abstract
Modern multi-service networks are inseparably linked with the commercial concept "tripleplay" that implies simultaneous provisioning of telephony, television and data transmissionover a single broadband connection. These services generate traffics of three types - unicast streaming, multicast streaming and elastic traffics. In this paper, we propose a multi-servicemodel of a triple play single-link network; we obtained an approximate formula for the stationary probability for the model; and finally, we find an exact algorithm for calculating performance measures by reducing the dimension of the problem.
