Packet Loss Test

Technology

So, at a basic level, when you connect, it downloads the web page over HTTPS, the site and the server then establish a WebSockets connection, and then the site and the server uses an external STUN server to negotiate a WebRTC connection. The site then establishes an unreliable data channel using WebRTC and sends a bunch of packets to the server, which records them and then sends them right back. The client then records the ping times and which ones it got back. The server also sends a log over WebSockets of which packets made it up, so that you can tell upload packet loss versus download packet loss.
