telecommunication network

The quality of service models of telecommunication networks was considered. The features of providing of quality of service in the telephone and computer networks was explored. On the basis of this research it sets, that the metropolitan telephone networks are characterized by a higher accuracy, dependability and security by comparison to the computer local area networks. Substantial advantage of computer local area networks above the metropolitan telephone networks is providing a higher speed of the user information transfer, although defect there is an instability of this speed.

The article deals with reasons why the planned network resource is not used completely. The main attention is paid to the dynamic routing protocol, which does not consider the current load of local network segments according to the principle of its functioning. In the paper local segments loading considers with existence of a constant flow to reduce the computational complexity of the proposed method. The method is proposed in the work to maximize the use of network resources and resource allocation improving based on alternative routes variation through less loaded local segment.
