The indicator for assessing the effectiveness of communication systems and their elements

The article offers an indicator of efficiency of communication networks and their elements, providing the possibility of their objective comparison at stages of creation, perfection and operation, and also an establishment of well-founded tariffs. The considered set of values of indicators of quality of functioning defines the conditions of elements of a network and a network as a whole and characterizes their loading ability.
The concept of stratification of a communication network, as a complex system, with the specifications of implemented protocols of transfer and processing and using the known analytical models based on systems of mass service or imitating modeling is considered. A method for defining an indicator of efficiency (MDIEF) and an optimum working point of functioning of a communication network and its elements are stated.
