08:00 – 09:00 Morning Coffee
09:00 – 09:15 Welcome and Introduction
09:15 – 10:30 Keynote – Lessons Learnt from Building and Operating CALLSTATS.IO
CEO and founder of CALLSTATS.IO, Finland.
callstats.io is “Analytics for real-time communications”. In this talk we will present how we measure service quality, detect and diagnose issues, and what type of issues can be automatically fixed. We analyse calls in real-time, hence the data processing is not limited by the call duration, even though the data stored per call may be large, for example, most interesting calls end up being 2+ GB of data. This talk will also touch upon the privacy aspects of handling vast amount of data. Lastly, the talk will cover interesting pieces of our architecture and results from our latest WebRTC industry report.

Iain R. Learmonth and Gorry Fairhurst
University of Aberdeen, Scotland.
Large network often contains devices to provide in-network functionality for economic or regulatory reasons. Mobile broadband networks are no exception to this. Either by design, through poor implementation, or misconfiguration, these devices can introduce impairments to user traffic. PATHspider is a tool that can be used to detect and measure such impairments. It has been used extensively to detect impairments in the core of the Internet and is also applicable to measuring from the mobile edge with the MONROE testbed. The MONROE testbed is the first European transnational open platform for independent, large-scale monitoring and assessment of the performance of mobile broadband networks in heterogeneous environments.
