Quality of service management based on Software Defined Networking approach in wide GbE networks

Abstract

This work experimentally demonstrates how to control and manage user Quality of Service (QoS) by acting on the switching on-off of the optical Gigabit Ethernet (GbE) interfaces in a wide area network test bed including routers and GPON accesses. The QoS is monitored at the user location by means of active probes developed in the framework of the FP7 MPLANE project. The network topology is managed according to some current Software Defined Network issues and in particular an Orchestrator checks the user quality, the traffic load in the GbE links and manages the network interface reconfiguration when congestion occurs in some network segments.

Software Defined Optical Networks (SDONs): A Comprehensive Survey

“…SDN controllers managed by the ISPs optimize the traffic flows to each user while accommodating large numbers of users and ensuring their minimum QoS. Additionally, Tego et al [371] demonstrated an experimental SDN based QoS management setup to optimize the energy utilization. GbE links are switched on and off based on the traffic levels.…”

“…SDN applications conduct active QoS probing to monitor the network QoS characteristics. Evaluations have indicated that the SDN based techniques achieve significantly higher throughput than non-SDN techniques [371].…”

Quality of Service monitoring adopting correlation among active and passive measurements: The experience from the FP7 mPlane project

“…Such alarms could be important input for network management, and in particular such anomaly detections could be used to make suitable changes in the network configuration, so that part of the traffic could be routed in some less congested links. For an instance other paths (physical or logical) could be switched on following a Software Defined Network (SDN) [12] approach as described in [13].…”
