Subject: [Bloat] ONTs and ITU - T G.988
Date: Wed, 12 Jan 2022 15:42:48 -0800	[thread overview]
Message-ID: <CAA93jw6D5QDTsHgi+4fsvbZPFo8cQ0RtPssmU5EDVjW7nb4bsg@mail.gmail.com> (raw)

Up until this point I haven't cared all that much about fiber, as most
of my observations were that it had "reasonable" buffering and all I
could hold in my head was the 802.11 standards. Since cablemodems are
well on their way to being fixed, wifi is looking good, and I recently
came across an ONT that was actually underbuffered, my holiday reading
consisted of pounding through a ton of fiber specs like this one:

https://www.itu.int/rec/dologin_pub.asp?lang=e&id=T-REC-G.988-201711-I!!PDF-E&type=items

There's a lot of promising info in this spec starting from page 104.

My 1st question is - are there any ONTs that actually do do pause
frames? Or providers that configure for them?

My second is - what is a cheap way to setup a lab to emulate a good,
common, version of gpon e2e?

Third - what OS do these things run? Who makes a "good" one?
