Benchmarking Methodology for Software-Defined Networking (SDN)
Controller Performance
Abstract
This document defines methodologies for benchmarking the control-
plane performance of Software-Defined Networking (SDN) Controllers.
The SDN Controller is a core component in the SDN architecture that
controls the behavior of the network. SDN Controllers have been
implemented with many varying designs in order to achieve their
intended network functionality. Hence, the authors of this document
have taken the approach of considering an SDN Controller to be a
black box, defining the methodology in a manner that is agnostic to
protocols and network services supported by controllers. This
document provides a method for measuring the performance of all
controller implementations.
