Micro-Operator driven Local 5G Network Architecture for Industrial Internet

April 15, 2019
Comments off

In addition to the high degree of flexibility and customization required by different vertical sectors, 5G calls for a network architecture that ensures ultra-responsive and ultra-reliable communication links. The novel concept called micro-operator (uO) enables a versatile set of stakeholders to operate local 5G networks within their premises with a guaranteed quality and reliability to […]

FlowVista: Low-bandwidth SDN monitoring driven by business application interaction

September 25, 2017
Comments off

Large enterprises are moving towards Software Defined Network (SDN) adoption, where business-critical applications are being deployed on top of highly programmable network components and orchestrated by a single or multiple controllers using network protocols, such as OpenFlow or NetConf for communication. Just like in traditional networks, low-cost monitoring solutions need to be developed for SDN. […]

OpenFlow based VoIP QoE monitoring in enterprise SDN

May 24, 2017
Comments off

The global view enabled by a Software Defined Network (SDN) architecture allows us to observe the contribution of each congested router to the overall Mean Opinion Score (MOS) degradation of a VoIP service. Thus, when a number of routers in the path may add to the MOS degradation, the SDN controller can quantify the contribution […]

Real-time monitoring of SDN networks using non-invasive cloud-based logging platforms

January 1, 2016
Comments off

The Software Defined Networking (SDN) paradigm enables quick deployment of software controlled network infrastructures, however new approaches to system monitoring are required to provide network administrators with instant feedback on a network’s health. This paper details the deployment of an SDN system architecture featuring the integration of a cloud-based, real-time log-analysis platform. The proposed architecture […]
