In 2013, the IEEE Future Directions Committee (FDC) formed an SDN work group to explore the amount of interest in forming an IEEE Software-Defined Network (SDN) Community. To this end, a Workshop on “SDN for Future Networks and Services” (SDN4FNS’13) was organized in Trento, Italy (Nov. 11-13 2013). Following the results of the workshop, in this paper, we have further analyzed scenarios, prior-...

The operational challenges posed in enterprise networks, present an appealing opportunity for the software-defined orchestration of the network (SDN). However, the primary challenge to realizing solutions built on SDN in the enterprise is the deployment problem. Unlike in the data-center, network upgrades in the enterprise start with the existing deployment and are budget and resource-constrain...

This paper describes the development of new methods and software leveraging Software Defined Networking (SDN) technology that has become common in terrestrial networking. We are using SDN to improve the state-of-the-art in design and operation of aerospace communication networks. SDN enables the implementation of services and applications that control, monitor, and reconfigure the network layer...

This work proposes a multicast algorithm on the basis of the extended Dijkstra’s shortest path algorithm for Software Defined Networking (SDN) to run on top of the controller. The proposed muticast algorithm is used to generate a multicast tree for a data publisher to deliver data packets to all subscribers so that every node and every host on the multicast tree will receive every packet once a...

Software-Defined Networks (SDN) and Network Function Virtualization (NFV) are two technologies that have already had a deep impact on computer and telecommunication networks. Software Defined Networks (SDN) decouple network control from forwarding functions, enabling network control to become directly programmable and the underlying infrastructure to be abstracted from applications and network ...

The Software Defined Networking (SDN) gained recognition due to its improvements at the packet switching and routing layers. The benefits of programmable, remotely controllable networking devices can be applied to the optical layer of contemporary networks as well. This work introduces CESNET's Czech Light~® family of devices and their role in enabling the SDN approach within the CESNET's produ...

This paper presents in the area of software defined networking. Our aim is to identify limitations of current networking technologies and how software-defined networks (SDN) could reduce cost, and improve competence to provide significant business value to many enterprises and campus Networks for their network management . These outcomes can lead to increased market potential for contenders whi...

The concept of software-defined networking (SDN) recently gained huge momentum in the industry, driven mainly by IT companies interested in datacenter applications. In this paper, however, we consider SDN applied in the carrier domain, which poses additional requirements on the network architecture, including network management functions. We derive concrete requirements for the use-case of a vi...
