Software Defined Networking (SDN) has emerged as a new network architecture for dealing with network dynamics through software-enabled control. While SDN is promoting many new network applications, security has become an important concern. This paper provides an extensive survey on SDN security. We discuss the security threats to SDN according to their effects, i.e., Spoofing, Tampering, Repudi...

In this paper, we posit that extension of SDN to support deeply and flexibly programmable, software-defined data plane significantly enhance SDN and NFV and their interaction in terms of (1) enhanced interaction between applications and networks, (2) optimization of network functions, and (3) rapid development of new network protocols. All of these benefits are expected to contribute to improvi...

The software defined networking (SDN) paradigm promises to simplify network configuration and resource management dramatically. Such features are extremely valuable to network operators and therefore, the industrial and the academic research and development communities are paying increasing attention to SDN. Although manufactures of wireless equipment are increasing their involvement in SDN-rel...

This white paper presents concept and solutions for virtualization of networks using Software Defined Networking. Software Defined Networking is an emerging trend in the networking and communication industry and it promises to deliver enormous benefits, from reduced costs to more efficient network operations. It is an architecture that allows network administrators to easily manage and introduc...

Software defined networking (SDN) has been the buzzword among networking professionals since the last few years. The three tiered architecture of SDN promises to simplify the network management. Unfortunately, a significant amount of research that is going on in this field is focused on datacenter networks. The societal impact that this technology can bring about mostly in developing countries ...

Cloud computing has transformed a large portion of the IT industry through its ability to provision infrastructure resources – computing, networking, storage, and software as services. Software-Defined Networking (SDN) has transformed the physical underlying network infrastructure into programmable and virtualized networks. Network Functions Virtualization (NFV) has transformed physical telecom...

The use of computing resources on network is becoming active in the Internet and private networks. OpenFlow/Software-Defined Networking (SDN) is drawing attention as a method to control network virtualization for the cloud computing services and other carrier services. This paper introduces examples of OpenFlow/SDN technologies applied to commercial cloud services. Various activities to expand ...
