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...

We explain the notion of software-defined networking (SDN), whose southbound interface may be implemented by the OpenFlow protocol. We describe the operation of OpenFlow and summarize the features of specification versions 1.0–1.4. We give an overview of existing SDN-based applications grouped by topic areas. Finally, we point out architectural design choices for SDN using OpenFlow and discuss ...

This paper presents a survey of recent work in the development of NetKAT, a formal system for reasoning about packet switching networks, and its role in the emerging area of software-defined networking.

OpenFlow is one of the most commonly used protocols for communication between the controller and the forwarding element in a software defined network (SDN). A model based on M/M/1 queues is proposed in [1] to capture the communication between the forwarding element and the controller. Albeit the model provides useful insight, it is accurate only for the case when the probability of expecting a ...

I. TUTORIAL OBJECTIVE The objective of the tutorial is to discuss the emerging concept of Software Defined Storage (SDS) with practical example. The overall objective of the tutorial: Participants can view a complete picture of storage–the traditional storage, storage in the cloud and the emerging Software Defined Storage. • Providers of storage hardware and software solutions can understand th...
