This article thoroughly details large-scale real world experiments using Software-Defined Networking in the testbed setup. More precisely, it provides a description of the foundation technology behind these experiments, which in turn is focused around OpenFlow and on the OFELIA testbed. In this testbed preliminary experiments were performed in order to tune up settings and procedures, analysing...

Software-defined networking is finding its way into optical networks. Here, it promises a simplification and unification of network management for optical networks allowing automation of operational tasks despite the highly diverse and vendor-specific commercial systems and the complexity and analog nature of optical transmission. A fundamental component for software-defined optical networking ...

Worldwide, electrical grids are developing into smart grids. To ensure reliability, robustness and optimized resource usage, these grids will need to rely heavily on modern information and communication technologies. To support the achievement of these goals in communication networks, we evaluated the possibility of using software-defined networking (SDN) infrastructure based on OpenFlow, to pr...

Modern network management is foremost a case of precise control: to implement practical traffic engineering and network security policies, a network operator needs to control the exact path traffic takes through a network. While conceptually simple, accomplishing this level of control is surprisingly difficult with traditional network control planes; in the end, the underlying distributed routi...

This paper proposes a Software Defined Networking (SDN)-based active content networking architecture for future media environments. The proposed architecture aims to provide customized delivery of various types of media content in order to satisfy various demands of users and service requirements. To this end, we have developed an active content processing model which provides in-network conten...

Unlike traditional networks which are statically configured, SDN control applications are dynamic and are becoming more heterogeneous and complex. There is a great need for a framework to reason about the behavior of the various SDN applications. To the best of our knowledge, current network modeling frameworks were not designed to incorporate the application logic into their models, and thus c...

Software defined infrastructures are computer infrastructures expressed in computer code. As software defined infrastructures is a young technology the body of scientific knowledge on the subject is small. This study aims at identification of quality aspects of software defined infrastructure projects by interviewing practitioners in the field. The result is a quality model containing quality c...
