The question of estimation and choice of a way of management of a telecommunication network in the conditions of considerable loading for various structures of traffic is considered. The requirements to the characteristics of the software switch for the simplest and self-similar input streams are analyzed and formulated. The expediency of increasing the number of independent parallel channels of the software switch with the organization of the general queue to several input ports is caused.
 The concept of the network management system is proposed, which consists in the use of a two-level model of the autonomous segment with a four-level model of the network as a whole. It is shown that the transition from centralized management to management of autonomous segments allows to increase the reliability of management systems and reduce the amount of service traffic.
