An SDN Framework bases on Meta-Model with Software-Defined Pricing (SDP)
                      draft-zhuge-sdnrg-sdn-sdp-04

Abstract

   This document defines a notion called Software-Defined Pricing (SDP)
   and introduces it into a Software-Defined Networks (SDN) framework.
   The SDN system with SDP inside is expected to promote the efficiency
   on SDN resources usage and ease management for service providers.

1.  Introduction

   Software-Defined Networks(SDN) is in the research process.  With the
   idea of SDN, networking resources like switches, routers and types of
   Network Elements (NEs)are managed as kinds of virtual resources,
   forming virtual networks so as to provide rather flexible services to
   network users.  In this research process, we noticed that how to
   price the services and the use of virtual network resources in an SDN
   is as critical as how the SDN is defined.  We consider that it seems
   a precious idea to treat a service pricing mechanism as part of the
   SDN framework and to manage it in a software-defined way.

   Network service prices are traditionally determined by service
   providers in a rather rigid way, which lacks of flexibility and
   sometimes even fairness to resources users.  By means of the idea of
   SDP, it is able to treat service pricing as a part of SDN, forming a
   service pricing model flexible to time, traffic and other network
   factors and status.  In this way, it is expected to promote the
   efficiency of SDN resources usage and ease the management for service
   providers.
