“…While QoS can be provided in OpenFlow switches or routers by configuring priority queues and mapping Flow Entries onto these priority queues, to the extent of our knowledge no available controllers provide a standardized management of queues and other works resort to virtualized frameworks [11].…”

Abstract-The evolution of Software-Defined Networking and the overall acceptance of protocols such as OpenFlow, demonstrates the added value of decoupling the data plane from the control plane. Existing SDN Controllers enable the expected flexibility from such networks by dynamically providing a finegrained control of each flow. However, hardware-specific configurations, such as the creation of queues or other mechanisms is out of the scope of these controllers. This work presents an extension to a well known OpenFlow controller (Floodlight) to efficiently handle the management of Traffic Control Queues in OpenFlow switches, resorting to a RESTful northbound interface. The obtained results demonstrate further possibility of developing innovative on-demand resource reservation mechanisms in SDN without adding unbearable overheads.

“…The work described in [13] enhances OpenFlow switches and Open-Flow testbeds with advanced QoS and virtualization capabilities, in order to make them capable of running QoS related experiments, but does not propose any specific QoS control model. In the other hand, [14] defines a per-flow driven approach, thus integrating the list of QoS control mechanisms equivalent to IP and per-flow regular approaches.…”

The Future Internet approach requires new solutions to support novel usage scenarios driven by the technological evolution and the new service demands. However, this paradigm shift requires deeper changes in the existing systems, which makes Internet providers reluctant in deploying the full transformation required for the Future Internet. The Entity Title Architecture (ETArch) is a holistic clean-slate Future Internet system embedding new services for these scenarios leveraging the Software Defined Networking (SDN) concept materialized by the OpenFlow. However, legacy ETArch deploys a fully per-flow approach to provision the same transport model for all sessions (equivalent to the Internet best-effort), while suffering with performance drawbacks and lacking Quality of Service (QoS) control. To that, we evolved ETArch with SMART (Support of Mobile Sessions with High Transport Network Resource Demand) QoS control approach, which coordinates admission control and dynamic control of super-dimensioned resources to accommodate multimedia sessions with QoS-guaranteed over time, while keeping scalability/performance and users with full Quality of Experience (QoE). The SMART-enabled ETArch system evaluation was carried out using a real Testbed of the OFELIA Brazilian Island, confirming its benefits in both data and control planes over the legacy ETArch.

“…Although it is similar to the framework here presented, it is limited to video streaming services and with limited expandability due to its single module architecture. Moreover, Sonkoly [14] proposes an integrated OpenFlow framework capable of running with different OpenFlow versions simultaneously and specifying QoS parameters.…”

The momentum around Software-defined Networking (SDN) is increasing. It has become clear that the network architecture needs to evolve to be able to provide current and next generation networking services, both from a performance and implementation point of view. However, most of the current SDN research has looked to specificities of SDN and few have looked from a full stack perspective. Although the former are essential, also the latter perspective needs to be taken into account. In this sense, our work proposes a complete and modular SDN framework targeted at connectivity services. This framework allows the creation and management of network connectivity services over an OpenFlow based network, with mechanisms of fault-management, as well as the optimal usage of the infrastructure. The performance results obtained from the SDN framework evaluation in a real environment show that the three different scenarios, service activation, link loss, and reaction to a new link, are dynamically supported with fast reaction to the network changes.
