WiFi networks are o en planned to reduce interference through planning, macroscopic self-organization (e.g. channel switching) or network management. In this paper, we explore the use of historical data to automatically predict tra c bo lenecks and make rapid decisions in a wireless (WiFi-like) network on a smaller scale. is is now possible with so ware de ned networks (SDN), whose controllers can have a global view of tra c ows in a network. Models such as classi cation trees can be used to quickly make decisions on how to manage network resources based on the quality needs, service level agreement or other criteria provided by a network administrator. e objective of this paper is to use data generated by simulation tools to see if such classi cation models can be developed and to evaluate their e cacy. For this purpose, extensive simulation data were collected and data mining techniques were then used to develop QoS prediction trees. Such trees can predict the maximum delay that results due to speci c tra c situations with speci c parameters. We evaluated these decision/classi cation trees by placing them in an SDN controller. OpenFlow cannot directly provide the necessary information for managing wireless networks so we used POX messenger to set up an agent on each AP for adjusting the network. Finally we explored the possibility of updating the tree using feedback that the controller receives from hosts. Our results show that such trees are e ective and can be used to manage the network and decrease maximum packet delay.

“…New services such as monitoring and new routing protocols can be added to network by adding different software modules to the controller, hence analyzing and controlling network behaviour. For this purpose, the controller also needs to communicate with underlying switches using standard protocols such as OpenFlow [4,7]. Figure 1 shows the SDN architecture which has three layers: an infrastructure layer consisting of OpenFlow switches, a control layer in which the controller is placed, and an application layer in which business applications can be placed.…”

“…As an example, Software Defined Networking (SDN) is proposed to create highly programmable computer networks. In SDN, the separation of the control plane from data plane gives network operators the ability to introduce new protocols and services to the network without any changes in the network hardware or infrastructure [4]. One of the most popular ways to deploy SDN is by implementing it based on an open standard protocol, named OpenFlow.…”

In recent years many claims about the limitations of todaysâ€™ network architecture, its lack of flexibility and ability to response to ongoing changes and increasing users demands. In this regard, new network architectures are proposed. Software Defined Networking (SDN) is one of these new architectures which centralizes the control of network by separating control plane from data plane. This separation leads to intelligence, flexibility and easier control in computer networks. One of the advantages of this framework is the ability to implement and test new protocols and architectures in actual networks without any concern of interruption.Named Data Networking (NDN) is another paradigm for future network architecture. With NDN the network becomes aware of the content that is providing, rather than just transferring it among end-points. NDN attracts researchersâ€™ attention and known as the potential future of networking and internet. Providing NDN functionalities over SDN is an important requirement to enable the innovation and optimization of network resources. In this paper first we describe about SDN and NDN, and then we introduce methods for implementing NDN using SDN. We also point out the advantages and applications of implementing NDN over SDN.
