OPEN CALL – SOFTWARE DEFINED NETWORKING

AUTOFLOW: AUTONOMIC OPENFLOW

EXPERIMENTATION FRAMEWORK FOR AUTONOMIC SOFTWARE DEFINED NETWORKS Kostas Tsagkaris, Vassilis Foteinos, Michalis Michaloliakos, George Poulios, Marios Logothetis, Panagiotis Demestichas Digital Systems, University of Piraeus UPRC Piraeus, Greece {ktsagk, vfotein, mmichal, gpoulios, mlogothe, pdemest}@unipi.gr Abstract—Autonomic Network Management (ANM) and Software Defined Networking (SDN) have appeared as promising technologies for simplifying the management and control of today's highly interconnected and complex networks. Although it seems that there is a strong link between these two technologies that can result in an efficient and useful interplay, consistent justification and positioning is still missing in the existing literature and industrial/research studies. The AUTOnomic openFLOW (AUTOFLOW) project aims at validating the synergy and interworking of ANM and SDN for the management and control of Future Networks by experimenting with the instantiation of an OpenFlow/SDN based ANM prototype, integrated with the OpenFlow/SDN testbed of GÉANT.

I. INTRODUCTION & MOTIVATION The rapid technological progress and unforeseen increase of highly dynamic and stringent users' traffic demands have brought a remarkable complexity in today's telecommunication networks and services. In consequence, progressively more complex and interconnected networking infrastructures are leading to an increasing difficulty in managing multi-vendor environments and services. Resorting to closed, proprietary solutions and patches on top of traditional management and control approaches cannot provide a viable way out for handling such complexity. What is really needed is an intelligent, flexible and costeffective network and service management solution so that the network could be better controlled and efficiently operated. To this end, several profound and emerging technologies are currently discussed in international research projects and standardization bodies. Two of the most important ones comprise the main subject of the AUTOFLOW project namely, Autonomic Network Management (ANM) and Software Defined Networking (SDN) . AUTOFLOW intends to study and shed light on the relationship among ANM and OpenFlow/SDN and make a position statement with respect to their possible synergy and interworking for the management and control of future networks (Figure 1). Furthermore, the project aims at validating and strengthening the above positioning by experimenting with the instantiation of an OpenFlow/SDN based ANM prototype in scenarios covering autonomic traffic engineering in core networks.
