Gene,
I think the lion's share of other people (many brilliant people here) on this
thread are focused on keeping latency down when under load. I generally just
read and don't contribute on those discussions, because that's not my area of
expertise. I only posted my point on bandwidth, not to detract from the
importance of reducing latency, but to correct what I believed to be an
important error on minimum bandwidth required to be able to perform standard
Internet functions.
To my surprise, there was pushback on the figure, so I've responded to try to
educate this group on streaming usage in the hope that the people working on
the latency problem under load (core reason for this group to exist) can also
be aware of the minimum bandwidth needs to ensure they don't plan based on bad
assumptions.
For a single user, minimum bandwidth (independent of latency) needs to be at
least 25Mbps assuming the goal is to provide access to all standard Internet
services. Anything short of that will deny users access to the primary
streaming services, and more specifically won't be able to watch 4K HDR video,
which is the market standard for streaming services today and likely will
remain at that level for the next several years.
I think it's fine to offer lower-cost options that don't deliver 4K HDR video
(not everyone cares about that), but at least 25Mbps should be available to an
Internet customer for any new Internet service rollout.
Cheers,
Colin

I am always surprised how complicated these discussions become. (Surprised
mostly because I forgot the kind of issues this community care about.) The
discussion doesn’t shed light on the following scenarios.
While watching stream content, activating controls needed to switch content
sometimes (often?) have long pauses. I attribute that to buffer bloat and high
latency.
With a happy household user watching streaming media, a second user could have
terrible shopping experience with Amazon. The interactive response could be (is
often) horrible. (Personally, I would be doing email and working on a shared
doc. The Amazon analogy probably applies to more people.)
How can we deliver graceful performance to both persons in a household?
Is seeking graceful performance too complicated to improve?
(I said “graceful” to allow technical flexibility.)
