          Terminology for Benchmarking SDN Controller Performance
              draft-ietf-bmwg-sdn-controller-benchmark-term-00

Abstract

  This document defines terminology for benchmarking an SDN
  Controller's performance. The terms provided in this document help
  to benchmark SDN controller's performance independent of the
  controller's supported protocols and/or network services. A
  mechanism for benchmarking the performance of SDN controllers is
  defined in the companion methodology document. These two documents
  provide a standard mechanism to measure and evaluate the performance
  of various controller implementations.

1. Introduction

  Software Defined Networking (SDN) is a networking architecture in
  which network control is decoupled from the underlying forwarding
  function and is placed in a centralized location called the SDN
  controller. The SDN controller abstracts the underlying network and
  offers a global view of the overall network to applications and
  business logic. Thus, an SDN controller provides the flexibility to
  program, control, and manage network behaviour dynamically through
  standard interfaces. Since the network controls are logically
  centralized, the need to benchmark the SDN controller performance
  becomes significant. This document defines terms to benchmark
  various controller designs for performance, scalability, reliability
  and security, independent of northbound and southbound protocols.
   
  Conventions used in this document
   
  The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
  "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
  document are to be interpreted as described in RFC 2119.
