Among the factors that determine the performance of a computationally intensive application running on a highperformance computing (HPC) system, communication between processes is vital. Our fundamental idea behind optimizing Message Passing Interface (MPI) communications is to maximize the utilization of the network of the cluster system, by deploying the Software Defined Networking (SDN) para...

The architectural principles of Software-Defined Networking (SDN) and its most prominent supporting protocol OpenFlow keep gaining momentum. SDN relies essentially on the decoupling of the control plane from the data plane, placing the former in a logically centralized component to be executed on commodity hardware the SDN controller. OpenFlow’s reactive programming enables the programming of t...

Researchers from all over the world are engaged in the design of a new Internet, and Software-Defined Networking (SDN) is one of the results of this engagement. Net-Ontology uses a SDN approach to bring semantics to the intermediate network layers and make them capable of handling application requirements and adapt their behaviour over time as required. In this paper we present an experimental ...

Software Defined Networking (SDN) is an approach to the deployment of future network infrastructures. SDN allows deal with different configurations to a crescent amount of virtualized network devices. In this paper, we offer a framework to support a number of network configurations through computational modeling and deployment of data paths between physical hosts for SDN. Computational modeling...

Software-Defined Networking (SDN) technologies offer the possibility to automatically and frequently reconfigure the network resources by enabling simple and flexible network programmability. One of the key challenges to address when developing a new SDN-based solution is the design of a monitoring framework that can provide frequent and consistent updates to heterogeneous management applicatio...

In the context of next generation 5G networks, the satellite industry is clearly committed to revisit and revamp the role of satellite communications. As major drivers in the evolution of (terrestrial) fixed and mobile networks, Software Defined Networking (SDN) and Network Function Virtualisation (NFV) technologies are also being positioned as central technology enablers towards improved and m...

Software-Defined Networking (SDN), display cases of a paradigm shift from traditional network towards a new era of Internet. This paper offers different attempts to integrate congestion control (cc) and load balancing by combining SDN approach in conjunction with Extended Johnson Algorithm applied for sparse graphs. This proposed algorithm takes into consideration not only edge weights but also...

Many communities have researched the application of novel network architectures such as Content-Centric Networking (CCN) and Software-Defined Networking (SDN) to build the future Internet. Another emerging technology which is big data analysis has also won lots of attentions from academia to industry. Many splendid researches have been done on CCN, SDN, and big data, which all have addressed se...

For a Software Defined Network (SDN), security is an important factor affecting its large-scale deployment. The existing security solutions for SDN mainly focus on the controller itself, which has to handle all the security protection tasks by using the programmability of the network. This will undoubtedly involve a heavy burden for the controller. More devastatingly, once the controller itself...
