Software Defined Networking (SDN) is considered as a new approach promising simplified networkmanagement by providing a programmable interface. The idea of SDN is based on the separation of control plane from the data plane in networking devices. This is achieved by having the networkintelligence centralised in what is called as SDN controller. In this paper we propose techniques for botnet detection in networks using…

Optimal Model for the Controller Placement Problem in Software Defined Networks
In this letter, we propose a mathematical model for the controller placement problem in SoftwareDefined Networks (SDN). More precisely, given a set of switches that must be managed by the controller(s), the model simultaneously determines the optimal number, location, and type of controller(s) as well as the interconnections between all the network elements. The goal of the model is to…
A Scalable Inter-AS QoS Routing Architecture in Software Defined Network (SDN)
All new networking architectures come with their own problems. Software Defined Networking (SDN) has its own challenges which are needed to be addressed by researchers as well. One of the crucial problems with SDN is the control plane scalability since it is a bottleneck for its evolution. As thenetwork grows, the number of messages a controller receives also increases. This increase puts…
Energy-aware allocation of reliable Virtual Software Defined Networks
The Internet is now present in our personal and professional life, where reliability and green communications are still open issues to be addressed. Usually, clients establish Service Level Agreements (SLAs) with their Internet Service Providers (ISPs), including parameters of reliability and bandwidth. On the other hand, the ISPs aim to maximize their profit by establishing…
Software defined networking-based vehicular Adhoc Network with Fog Computing
Vehicular Adhoc Networks (VANETs) have been attracted a lot of research recent years. Although VANETs are deployed in reality offering several services, the current architecture has been facing many difficulties in deployment and management because of poor connectivity, less scalability, less flexibility and less intelligence. We propose a new VANET architecture called FSDN which combines…
Realization of congestion in software defined networks
Software defined networking[1][9] has brought a rapid change in networking industry by providing programmability and abstraction. it also enables centralization of control in infrastructure. In this paper, we describe the results of our experiment to determine the performance of SDN by simulating Open vSwitch under conditions of congestion. We did experiments on MININET by creating four compute nodes and…
NDNFlow: Software-defined Named Data Networking
In this paper, we introduce NDNFlow: an open-source software implementation of a Named DataNetworking based forwarding scheme in OpenFlow-controlled Software-Defined Networks (SDNs). By setting up an application-specific communication channel and controller layer parallel to the application agnostic OpenFlow protocol, we obtain a mechanism to deploy specific optimizations into a networkwithout requiring a full network upgrade or OpenFlow protocol change. Our open-source softwareimplementation consists of both…
Video streaming over software defined networks with server load balancing
Software Defined Networking is a promising Internet architecture to deliver multimedia with end-to-end quality of service (QoS) since it enables optimal dynamic management of network resources and on-demand QoS provisioning by a network operator. We propose a framework for server load-balancing over a single-operator OpenFlow network to improve the quality of service levels of video streaming services. We design a new OpenFlow controller application…
Dynamic Resource Discovery Protocol for Software Defined Networks
In Software Defined Networking (SDN), the network management is logically centralized but physically distributed among the controllers to improve the scalability compared with a completely centralized model. As an alternative to managing the network state in SDN in a distributed way, this work proposes a distributed protocol called SDN Resource Discovery Protocol (SDN-RDP). This protocol divides and distributes the network management among the controllers. In…
Software defined networking applied to the heterogeneous infrastructure of Smart Grid
The increased need for power quality monitoring and active control of distribution grid necessitates the introduction of the Smart Grid (SG) approach, requiring an efficient ICT system for the monitoring and control of distribution grid state. The main obstacle to deployment of SG in real system is the lack of an efficient communication infrastructure. The…
