WebRTC Metrics
A comprehensive overview of WebRTC statistics, derived indicators, and observable signals, to better understand call quality, connectivity, and user experience in rtcStats
Too many network interfaces
This can significantly increase ICE connectivity checks across available network interfaces. This may slow down connection setup, generate unnecessary network traffic and potentially route the connection to the wrong network interface.
Description
WebRTC gathers candidates from every single network interface available on the device (Wifi, Ethernet, VPN, Virtual machine, mobile network, ...).
Having too many network interfaces multiply the number of candidates gathered and consequently, the number of connectivity checks done.
On some low powered device, this can block or crash the network adapter making the connection impossible.
What do we do here?
We count the number of network interfaces found and if greater than 4, we mark an observation.
