Comment (by cohosh):
I had a thought about how this might also be used for better overall
network health (particularly as a potential solution for #25681). I could
envision a browser proxy peforming the following set of steps at startup:
- Do the various checks we already have for WebRTC permissions and a probe
of the Snowflake bridge
- Request a throughput check from a probe point we run (perhaps we can use
the same machine that hosts bridgestrap from #31874, which is conveniently
already written in Go)
- The probe point will craft an offer and exchange SDP information with
the proxy and then proceed with a download/upload test. The probe point
will gather throughput statistics from this test, sign them, and hand them
to the proxy.
- When the proxy polls the broker, it sends the signed throughput
statistics in the poll. The broker can then either priortize proxies based
on their throughput or use an implementation of #25598 to inform the proxy
how often to poll based on their throughput and the current need
