The Concept of an Adaptive Network Resources Control Mechanism

Abstract

The concept of a mechanism for adaptive control of resources available in a corporate computer network is considered. The main trends in the development of computer networks are described, and the main problems requiring additional research and development are pointed out. The existing methods for distributing load among the available network resources in an automated manner are subjected to a comparative analysis. A mechanism for adaptively altering the network users’ priorities and redirecting the transactions forming the data traffic flows in the peak load modes on the basis of software-defined networking principle is proposed. An algorithm for implementing the developed mechanism is presented. The objective that has been set forth is solved by integrating a dedicated controller into the corporate computer network topology. The abovementioned controller is essentially a computerized module that performs the basic functions of monitoring the network resources, identifying the priority pairs of users initiated the transmission of data blocks, determining the backup routes, creating a data flow tables, and assigning the shaped flows to the network switches. An example corporate computer network is considered, in which high-performance host machines exchange large amounts of data in the real time mode using the main and backup communication channels. The feasibility of the proposed concept of the adaptive network resource control mechanism has been confirmed experimentally. The results of experimental testing carried out on a corporate computer network fragment are presented, which confirm an increase in the data transmission rate between a pair of priority users in comparison with the channel aggregation mechanism.
