ABSTRACT A new approach to the software-defined networks modeling is proposed. A
feature of this approach is a possibility of modeling and analysis of boundary service quality …

The frst part of the article provided an overview of the basic principles of the promising
direction of modeling and analysing infocommunication networks and systems-Network …

Mathematical models of the switch and controller of software-defined networks are built, on
the basis of which formulas are derived for estimating the time delays in the …

The authors of the article focus on the concept of a software defined network. In the
beginning, the brief historical account is given concerning software defined networks as a …

Implementing the almost limitless possibilities of a software-defined network requires
additional study of its infrastructure level and assessment of the telecommunications aspect …

The analysis carried out shows [1, 2] that software defined networks (SDN, Software Defined
Networks) are based on the idea of a telecommunication network as a network that has a …

Methods and mathematical tools for formalization analysis and verification of Software-
Defined Network protocols are suggested in the paper. E-networks apparatus and linear …

A method of data transmission using a scheduler and a delivery control function in software-
defined networks is proposed, and an algorithm for its operation is developed. A possible …

Existing networks are based on equipment that is a monolithic physical elements. Each
element of the network has features that depend on the manufacturer. This does not allow …

The article describes the proposed approach to modeling stochastic processes of the
boundary layer of complex systems with a network topology, based on the methods of …
