Dynamic reconfiguration and network programmability are active research areas. State of the art solutions use the Software Defined Networking (SDN) paradigm to provide basic data plane abstractions and programming interfaces for control and management of these abstractions; however, SDN technologies are currently limited to wiredions; however, SDN technologies are currently limited to wired net...

SDN as a network architecture emerged on top of existing technologies and knowledge. Through defining the controller as a software program, SDN made a strong connection between networking and software engineering. Traditionally, network programs were vendor specific and embedded in hardware switches and routers. SDN focuses on isolation between control and forwarding or data planes. However, in...

Software Defined Networking (SDN) is an emerging promising paradigm for network management because of its centralized network intelligence. However, the centralized control architecture of the software-defined networks (SDNs) brings novel challenges of reliability, scalability, fault tolerance and interoperability. In this paper, we proposed a novel clustered distributed controller architecture...

The first OpenFlow Software-Defined Network (SDN) Controller, NOX, was developed by Nicira Networks and donated to the research community in 2008. Almost 10 years later, there are at least 29 open-source SDN Controllers and many more proprietary solutions. Two of the open-source SDN controllers stand out in terms of broad deployment and strong contributor base; Open Network Operating System (ON...

In this paper, we propose an architecture based on software-defined networking (SDN) for wireless sensor networks. Ideas of how to design and make use of the flexibility that SDN offers are presented. We discuss how SDN principles can lead to the use of commodity hardware in a wider range of WSN deployments and then tailor the software only to meet the requirements of the specific deployments a...

The Software Defined Network (SDN) and Network Function Virtualization (NFV) architectures are composed of different functional blocks such as NFV Orchestrator, Virtualized Infrastructure Manager (VIM) and SDN controllers. These components are modeled as independent software with specific access, configuration, and management. They are connected mainly across of the Application Programming Inte...

The term Software Defined Networking (SDN) is prevalent in todays discussion about future communication networks. However, no consistent definition regarding this technology has formed, yet. The fragmented view on SDN results in legacy products being passed off by equipment vendors as SDN, academics mixing up the attributes of SDN with those of network virtualization, and users not fully unders...
