The System Research of Reliability Indexes of Infocommunication Networks with Distributed Structure

In this article the questions of the system research of reliability indexes of the infocommunication network with distributed structure are considered. As a criterion proposed use the reliability index, based on reliability state of each level of the considered network. Showed that development of methods and algorithms of system research of reliability indexes of the infocommunication network in terms of workload of its components is one of the main problems in the design of network with a complex structure. The model that allows a system approach to research the reliability indexes of the infocommunication network are proposed. The infocommunication network with a distributed structure are introduced as a system consisting of K interacting subsystems (level). The main factors of reliability state of equipments (gateways, routers, switches, Softswitch and other) of each lever are described by vector-functions. By these vector-functions given own reliability operators of infocommunication network.
