SDN/OpenFlow solutions have shown their strengths in datacenter, cloud and experimental environments. Currently there is a number of activities employing SDN concepts to other use cases. The ADDONAS project (Active Distributed & Dynamic Optical Network Access Systems) proposed to use SDN concept to support access to the services for the users and fair access to the resources for service providers. This paper presents the work done in the ADDONAS project, discusses architecture and describes development related to deployment of the SDN system to enable flexible service provisioning in combined metro and access architectures.

The ability to deploy applications which control network resources using a global view is a major benefit of the SDN paradigm. The SDN dataplane is comprised of a topology of forwarding elements programmed by a centralized controller over a common, well-defined interface. We believe that the heterogeneity of forwarding devices is an inherent property of software defined networks rather than a side effect. Therefore it is vital to design SDN frameworks in manner which explicitly takes variable hardware capabilities into account. In this work we argue that the concurrent operation of switches with diverse capacities for control message processing leads to unpredictable delays in SDN applications. To address this issue, we use a queuing model to characterize the service of a switch's control interface. Furthermore, we outline a measurement based-approach to derive the corresponding parameters. We propose a simple interface extension for controller frameworks which enables operators to configure delay bounds for transmitted control messages. As a result, developers can create SDN applications which exhibit consistent and predicable behavior.

This paper considers SDN, and OpenFlow in particular, as technology to develop the next generation of more flexible, configurable and automated home networks. We identify the problems with the current state of the art in home networking, which includes a lack of user engagement in home network maintenance and configuration, Internet bandwidth limitations, and a lack of ISP reconfiguration and troubleshooting tools. We propose HomeVisor, a novel remote home network management tool. In this paper, we evaluate HomeVisor's ability to outsource control to an entity outside the home network. This includes the overhead of multiple slices within the home, and the effect of controller latency on network performance.

Packet scheduling is essential to properly support applications on Software-Defined Networking (SDN) model. However, on OpenFlow/SDN, QoS is only performed with bandwidth guarantees and by a well-known FIFO scheduling. Facing this limitation, this paper presents the QoSFlow proposal, which controls multiple packet schedulers of Linux kernel and improve the flexibility of QoS control. The paper assesses QoSFlow performance, by analysing response time of packet scheduler operations running on datapath level, maximum bandwidth capacity, hardware resource utilization rate, bandwidth isolation and QoE. Our outcomes show an increase more than 48% on PSNR value of QoE by using SFQ scheduling.

Software defined networks are poised to dramatically simplify deployment and management of networks. OpenFlow, in particular, is becoming popular and starts being deployed. While the definition of the "northbound" API that can be used by the new services to interact with an OpenFlow controller is receiving considerable attention, the traditional, "southbound", API that is used to program OpenFlow switches is far from perfect. In this paper, we analyze the current OpenFlow API and its usage in several controllers and show semantic differences between the intended and actual use. Thus, we argue for making the OpenFlow API clean and simple. In particular, we propose to mimic the process that exists in the Python community for deriving changes that result in a preferably only one, obvious way of performing a task. Toward this end, we propose three OpenFlow Enhancement Proposals: i) providing positive acknowledgment, ii) informing the controller about "silent" modifications, and iii) providing a partial order synchronization primitive.

The efficient utilization of emerging new technologies for the sake of implementing attracting and novel network architectures is a major research challenge. As traditional addressing schemes seem to be rather inefficient to cope with emerging Internet technologies, research concerning Content Centric Networks (CCNs) has received a lot of attention by the research community. CCNs are designed to treat content as a primitive and therefore overcome the obstacles posed by traditional addressing schemes. Utilizing Software Defined Networking (SDN) approaches can lead to a realistic implementation of CCN scenarios. In this paper, we exploit the OpenFlow (OF) technology, an SDN enabler, in order to efficiently create and manage CCNs which are backward compatible with already existing networking infrastructure. We evaluate our scheme by using different load balancing policies, based on the actual network state at every observation interval. The process is completelly transparent to the end user, making our approach an easy to integrate solution for all existing networking topologies. Our solution is implemented and evaluated under a real life scenario, utilizing distributed testbed resources, consisting of the NITOS wireless testbed and PlanetLab-Europe (PLE).

Traffic demands in mobile networks are expected to grow substantially in the next years, both in terms of total traffic volume and of bit-rate required by individual users. It is generally agreed that the only possible solution to overcome the current limitations is to deploy very dense and heterogeneous wireless networks, which we call DenseNets. However, simply scaling down existing networks by orders of magnitude, as required to fulfill traffic forecasts, is not possible because of the following constraints: i) the bottleneck would shift from the Radio Access Network (RAN) to the backhaul, ii) control overhead, especially related to mobility management, would make the network collapse, iii) operational costs of the network would be unbearable due to energy consumption and maintenance/optimisation. In this paper, Software Defined Network (SDN) for mobile networks is claimed as the paradigm shift necessary to tackle adequately the above challenges. A novel architecture is proposed, which supports DenseNets made of overlapping LTE and WLAN cells connected to the core network via a reconfigurable backhaul.

Application-Aware Networking is a promising approach to provide good application quality to users in scenarios with limited network resources, like today's access networks. With SDN, a particularly interesting method to enable flowbased traffic management in networks has become available. In this work we take a look at how a specific application, i.e., YouTube Streaming, can benefit from such an SDN-based Application-Aware Network. We implement and investigate an approach based on Deep Packet Inspection (DPI) and one based on direct information input from the application in an OpenFlow testbed in order to show, how these different types of application information can be exploited to enhance the Quality of Experience (QoE). Furthermore, we determine the overhead caused by each of the presented approaches.

Nowadays, while most of the programmable network apparatus vendors support OpenFlow, a number of fragmented control plane solutions exist for proprietary Software - Defined Networks. Thus, network applications developers are forced to re-implement their solutions every time they encounter a new network controller. Moreover, different network developers adopt different solutions as control plane programming language (e.g. Frenetic, Procera), severely limiting code sharing and reuse. Despite having OpenFlow as candidate standard interface between the controller and the network infrastructure, interoperability between different controllers and network devices is hindered and closed ecosystems are emerging. In this paper we present the roadmap toward NetIDE, an integrated development environment which aims at supporting the whole development lifecycle of vendor - agnostic network applications.

Universal access to Internet is crucial. Several initiatives have recently emerged to enable wider access to the Internet. Public Access WiFi Service (PAWS) enables free Internet access to all and is based on Lowest Cost Denominator Networking (LCDNet) -- a set of network techniques that enable users to share their home broadband network with the public. LCDNet takes advantage of the available unused capacity in home broadband networks and allows Less-than-Best Effort (LBE) access to these resources. LCDNet can enable third-party stakeholders, such as local governments, to setup, configure and operate home networks for public Internet access in cooperation with Internet Service Providers. Software-defined networking (SDN) creates new opportunities for the remote configuration and management of such networks at large scale. In this paper, we present Virtual Public Networks (VPuN), home networks created, deployed and managed through an evolutionary SDN control abstraction. This offers more flexibility to users and network operators, allowing them to share and control the network, while providing opportunities for new stakeholders to emerge as virtual network operators.
