Balázs Kreith of the open-source WebRTC monitoring project, ObserveRTC shows how to calculate WebRTC latency – aka Round Trip Time (RTT) – in p2p scenarios and end-to-end across one or more with SFUs. WebRTC’s getStats provides relatively easy access to RTT values, bu using those values in a real-world environment for accurate results is more difficult. He provides a step-by-step guide using some simple Docke examples that compute end-to-end RTT with a single SFU and in cascaded SFU environments.

Optimizing WebRTC Power Consumption (Markus Handell)
The performance of WebRTC in Chrome as well as other RTC applications needed to be improved a lot during the pandemic when more people with a more diverse set of machines and network connections started to rely on video conferencing. Markus Handell is a team lead at Google who cares a lot about performance of […]
How does WebRTC End-to-End Encryption work? Matrix.org example (Dave Baker)
One of WebRTC’s great features is its mandated strong encryption. Encryption mechanisms are built-in, meaning developers don’t (often) need to deal with the details. However, these easy, built-in encryption mechanisms assume you have: 1) media is communicated peer-to-peer and 2) a secure signaling channel setup. Most group-calling services make use of a media server device, […]
Apple’s not so private relay fails with WebRTC
Apple released iOS 15 with iCloud Private Relay broken for WebRTC – it still divulges your IP address. This post walks through why and how the WebRTC API’s use your IP address information and how you can check what IP addresses are gathered.
