Method for Constructing the Topological Structure of an Access Network with a Distributed Structure

The article proposes a method for constructing the topological structure of the access network of the information and communication network (ICN), which has a distributed structure. The essence of the method is reduced to the fact that initially the region is divided into zones, then in each zone a star-shaped graph with a vertex in one of the possible locations of the switch is formed. When forming the subnet structure in the next zone, a fixed set of terminal systems adds the point where the switch of the previous zone is located. This approach allows, in the construction of a subnet topology in zones, to simultaneously form one connected (core) topology of the backbone network between the zones. In the next stage, the topology of the desired K-connected structure of the distributed access network of the ICN is constructed. The problem is solved by using sections of dominant sets and P-medians of graph theory.
