If network data is big data, we've got no option but to climb up the slope of enlightenment. Is the problem we have in network data analytics really a big data problem? … Continue reading Is network data big data?
Closed loop network control is much hyped at the moment, and with good reason; the potential operational savings and service improvements from using the output of analytics to trigger orchestration and control functions to react to problems dynamically, or to automatically optimise the deployed infrastructure and services, are significant. We’ve previously discussed this in ETSI NFV … Continue reading Feedback loops and closed loop control

In a previous post I talked about integrating OpenDaylight with PNDA. In this post I will start to make use of the data coming from OpenDaylight by building a Spark streaming application to create time-series datasets. This lets us use the Grafana application in PNDA to display time-series graphs. For this example, I have used this if-table-collector OpenDaylight … Continue reading Working With Time-series Data in PNDA
