Conceptual bases for managing the processing and distribution of discrete flows in a multicommodity communication network. Part I. Hierarchical structure of the network and principles of sorting and distribution of flows

The article discusses methodological approaches to the construction of multicommodity hierarchical communication networks and identifies the main tasks of processing and distribution of discrete correspondence flows, which allow to create favorable conditions for reducing material, financial and labor costs in transport systems with further mechanization and automation of production. Multicommodity communication networks are characterized by the presence of a multitude of sources and drains of correspondence flows (products or requirements). Correspondence is understood as a pair of different network nodes, between which there is a directed (addressed) discrete flow of elements (for example, indivisible loads of uniform size, bits or symbols) of a given size. In a multicommodity network, all correspondence flows are subject to a one-time transfer from sources to drains. In general, a certain set of types (categories) of correspondence can be defined on the network, differing in weight, dimensions and other characteristics, but having common sources and drains. The hierarchical structure of the network and the principles of sorting, distribution and routing of flows are given.
