Software Defined Networking
Current networking technologies are based on systems originally designed over 40 years ago and in an environment that was relatively static. Software Defined Networking allows greater network flexibility and the potential for new networking paradigms to meet new networking demands.
There are six projects in the Software Defined Networking category, each with a briefing below:
|
AUTOFLOW: Autonomic OpenFlow
(University of Piraeus Research Center)
Objective:
To extend the GÉANT testbed towards an AUTOnomic OpenFLOW (AUTOFLOW) facility and perform focused research and experimentation, in order to demystify this relationship and showcase that Software Defined Networking (SDN)/OpenFlow capabilities can bring "customizable Autonomic Network Management (ANM)" into reality.
Approach:
ANM and 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 among these two technologies, which can result in an efficient and useful interplay, consistent justification and positioning is still missing in the existing literature and industrial/research studies. An SDN-enabled ANM is a challenging target that can be used to test the usability and limits of the testbed and to provide feedback for its extension and fine-tuning. It can also leverage the interest of the research/academic community, thus contributing to the extension of the facility's user base.

CoCo: On Demand Community Connection Service for eScience Collaboration
(SURFnet; TNO)
Objective:
Develop a proof of concept for a novel on-demand connectivity service for research communities and education communities connected through participating NREN networks and the GÉANT network.
Approach:
CoCo enables scientists to dynamically create a private and secure virtual network in which scientists can share resources, such as Virtual Machines (VMs), storage, microscopes and other facilities, amongst collaborators. CoCo's services are exposed through a simple and easy to use interface via the Internet, which developers can also include in their applications. CoCo automatically sets up and manages a virtual network for a community across multiple domains, considering mobility, redundant paths, and fail-over of network connections. Consequently, CoCo's virtual networks are more agile, efficient, and robust than manually created virtual networks.

DREAMER: Distributed REsilient sdn Architecture MEeting carrier grade Requirements
(CNIT University of Rome; Create-NET; GARR)
Objective:
To investigate how a network based on an OpenFlow/SDN control plane can provide the same functionalities of an IP/MPLS control plane, offering a carrier grade approach to resiliency and fault management.
Approach:
DREAMER focuses on introducing and exploiting SDN capability in carrier grade IP backbones. DREAMER will consider the operational requirements coming from the GARR National Research and Education Network (NREN) to drive the design of the solutions, and will study its applicability to the GÉANT backbone network.
Events:
DREAMER will have two OSHI-related presentations in the forthcoming months:
Software Defined Networking and its applications, June 2014
Organised by DREAMER, this workshop focused on the application of SDN technology and its evolution from an R&D perspective.

DyNPaC: Dynamic Path Computation Framework
(University of the Basque Country)
Objective:
To investigate how GÉANT Connectivity Services could be provisioned in a future scenario with a clean slate approach based on an SDN enabled infrastructure.
Approach:
Nowadays, GÉANT Connectivity Services are offered upon the deployed pre-SDN infrastructure (e.g. switches, routers and optical equipment). Currently, GÉANT offers flexible IP and P2P connectivity options. The former provides a shared IP infrastructure (i.e. GÉANT IP), whereas the latter provides static point-to-point connections (i.e. GÉANT Plus and GÉANT Lambda) and dynamic provisioning of circuits (i.e. GÉANT Bandwidth on Demand). This project investigates how this type of services could be provisioned in a future scenario with a clean slate approach based on a SDN enabled infrastructure. The main output of this research is a comprehensive model / framework / architecture to provision connectivity services based on the SDN technology.

MINERVA: Implementing network coding in transport networks to increase availability
(MTA-BME Future Internet Research Group; i2cat)
Objective:
To deploy a robust network coding architecture in the GÉANT OpenFlow facility, which provides a highly available backbone network infrastructure for Future Internet applications.
Approach:
MINERVA’s goal is to minimize the number of network coding nodes, as well as the complexity of the coding operations which have to be performed to provide capacity-efficient protection with instantaneous recovery. The benefits of MINERVA’s resilient network architecture will be demonstrated on two application scenarios, namely distributed storage and video streaming.

MOTE: Multi-Domain OpenFlow Topology Exchange
(Universiteit van Amsterdam; SURFsara)
Objective:
To allow users to create and tune end-to-end network connections that cross many OpenFlow domains.
Approach:
MOTE will research multi-domain topology descriptions supporting network provisioning for Software Defined Networking (SDN) technologies. In particular, it will bridge the intra-domain operations of OpenFlow with the inter-domain provisioning in the Network Service Interface (NSI) Framework. The methods for describing and exchanging topology descriptions will allow users to create and tune end-to-end network connections, even those crossing many OpenFlow domains.
