Bandwidth Estimation in the Janus WebRTC Server

Bandwidth estimation (BWE) is a fundamental component of WebRTC as a technology, and a tricky one to tackle in a server, that typically just relays streams rather than encoding them itself, and as such with less finer control on the outgoing bitrate. This presentation will describe our efforts on trying to implement such a functionality in the Janus WebRTC Server, and the related challenges.
