Evaluation of Telecommunication Equipment Delays in Software-Defined Networks

Abstract

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 telecommunications equipment of these networks. The dependencies of the time delays in the switch and the controller on the main equipment parameters, which have a major effect on the delays, are also obtained. The obtained results can be used in the design of software-configured networks in the context of various informational impacts (for various input information flows) with a given level of quality of service.
