Data-driven prediction of service metrics in real-time
Rolf Stadler. KTH – Royal Institute of Technology, Sweden
Abstract: We start with discussing the opportunities of using machine learning for network and cloud engineering and operation. We then focus on the specific problem of KPI estimation and present an approach that is based based upon statistical learning, whereby the behavior of a system is learned from observations. Following this approach, we collect device statistics from servers and switches on a testbed and use regression techniques to predict client-side service metrics for a video service and a key-value store. We further discuss design and implementation of a real-time analytics engine, which processes streams of device statistics and service metrics from testbed sensors and produces model predictions through online learning.
