Matrix-graph models of computer network

In mathematical theory and informatics graph is a set of ob-jects with relationship between of them. The objects introduce as tops, or nodes of graph, but relationship - as arcs, or edge. For miscellaneous application types graph can differ the directivity, restrictions on amount of the relationships and additional given about top or edge. Many structures which are presenting practical interest in mathematics and informatics, can be presented as graph. In particular, models of graph are broadly used for analysis and syntheses of the processes to routings in computer set.
