摘要
Software-defined network (SDN) is an emerging network architecture that can be adapted as a building block for cloud-enabled data centers. SDN decouples the traditional network in Data Plane (collection of forwarding devices or OpenFlow-enabled switches) and Control Plane (collection of one or more controllers), which communicates with each other using OpenFlow protocol. Proper installation of SDN necessitates the performance test of OpenFlow-enabled switches and controllers. Efficiency, reliability, and scalability are few parameters that should be considered to calculate the efficiency of an OpenFlow-based SDN. An analytical model of the OpenFlow-based network is suggested in this paper. Our proposed model is based on queueing theory and exponential models. The average packet arrival rate of a controller and maximum waiting time for an OpenFlow-enabled switch to get a PACKET_OUT message are taken as parameters to define our approach.
