The pull of Software-Defined Network- ing (SDN) is magnetic. There are few in the networking community who have escaped its impact. As the benefits of network visibility and network device programmability are discussed, the question could be asked as to who exactly will benefit? Will it be the network operator or will it, in fact, be the network intruder? As SDN devices and systems hit the mark...

The software-defined networking (SDN) paradigm has recently emerged as a trend to build various protocols, develop more reliable networks, enhance the data flow controlling, and provide security in much simpler flexible way. SDN helps ease management handle asymmetric connectivity across nodes. It solves problems of network cloud hence provides best solution for safety on network. Therefore, we...

The rapid rise in popularity of multimedia applications, such as VoIP, IPTV and Video Conferencing, intensifies the need to consider resource management for user satisfaction. Furthermore, improving Quality of Experience (QoE) in Software Defined Networks (SDNs) services is one of the important issues to be addressed by provisioning optimum resource management. In this paper, resource allocatio...

R ECENTLY, leading equipment providers in the network infrastructure market launched the first software-enabled appliances that support network virtualization capabilities. The main advantage of Software-Defined Networking (SDN) is the separation of network control and forwarding and the fact that it allows flexible management of the network resources. OpenFlow is currently the most prominent S...

Software-Defined Networking currently appears to be a major evolution towards network programmability. In this paper, we first analyze the network management capabilities of OpenFlow in order to identify the main challenges that are raised for SDN management. We address current deficiencies of SDN management and suggest solutions that incur research directions to be carried out for the manageme...

Software-Defined Networking (SDN) has the potential to automate and radically simplify management of computer networks—today a manual, error-prone task. Many networks however, especially enterprise networks, face a deployment problem: How to migrate an existing network to SDN? SDN must be introduced incrementally to build confidence and respect infrastructure budget constraints. In this article...

Three concepts (a) network programmability by clear separation of data and control planes and (b) sharing of network infrastructure to provide multitenancy, including traffic and address isolation, in large data center networks and (c) replacing the functions that traditionally run on a specialized hardware, with the software-realizations that run on commodity servers have gained lot of attenti...
