The analysis of process of communication of data control is conducted in multiservice networks. Cause of origin of overload and loss of packet are studied in the networks of telecommunications. For upgrading functioning telecommunication a network it is suggested to create the system of estimation of parameters of network. As a result of the conducted theoretical researches of carrying capacity of network, guided protocol of TCP, on the basis of approach, oriented to the study of network structure, the new method of research is offered.
