@dchapiro These forums are for JackTrip users, so please refrain from using them to promote your own projects, especially doing so with misinformation, and reposting the same thing across several different inactive threads (our software flagged these duplicate promo posts as spam. I allowed this one but removed the others).
There are a number of obvious things that are factually incorrect in your PDF. For example, JackTrip is free open source software (MIT license). JackTrip can also be used as a peer-to-peer client. It started out only supporting peer-to-peer, but we later added more options because there are rarely any advantages, including with regards to latency. Only in extreme cases (or extreme settings configurations) does peer-to-peer provide latency advantages.
My bigger concern is that your measurements indicate you clearly have something setup incorrectly. Our published results demonstrate 25 ms from San Francisco to Portland using default settings, and it’s very easy to reproduce these. Having been doing this for years, anything over 25 ms on Fiber in the SF bay area is not remotely believable to me.
With a few strategic settings changes in JackTrip, such as bumping up the buffering settings or using a location on the other side of the world, it’s pretty easy to generate latencies over 100 ms latency as well…
