Calculations of excess load on the network

Abstract

In the modern world, digital technologies have an important role in the development of national economies. Digital technologies have advantages: facilitating public and business access to public services, accelerating the exchange of information, the emergence of new business opportunities, creating new digital products, etc. Accessibility, stability and security of data transmission on the Internet are the technological basis for the development of all industries, as well as the high quality of life of the population. The exchange of information in communication networks in digital form has several advantages such as: a high level of noise immunity and the highest quality in data transmission; the ability to use standard reliable and cheap integrated circuits, which significantly reduces the cost of switching and compaction systems, which are decisive in the cost of the entire network; a great opportunity when combining and processing information of various types in digital form. Currently, most methods for assessing the quality of user service on communication networks used in the design either consider the problem in relation to one-dimensional traffic or do not take into account the influence of a finite number of load sources. This limits its using in solving design problems of multiservice networks, including in areas of subscriber access networks. In this regard, this article discusses a broadband digital network with service integration, based on the ATM technology, which implements an iterative method where the flow distribution is specified by the route matrix, and the load distribution between nodes of each pair of nodes is made through the path tree, obtained by the route matrix when calculating this pair, as well as the development of a mathematical method for calculating the excess load of an asynchronous network when transmitting information traffic by the method of channel switching and packet switching.
