I'd love to see one of those. Can I get on it?
=A0
I have
10G to the internet but am only using about 2G of that. =A0This is the
server side of a network talking to millions of clients. =A0The clients
in this case are on "lossy" wireless networks where packet loss i= s not
an indication of congestion so much as it is an indication that the
client moved 15 feet behind a pole and had poor network connectivity
for a few minutes.

Or is using multicast.
=A0
The idea being that in today's internet, packet loss is not a good
indication of congestion. =A0Often it just means that the radio signal
has been briefly interrupted. =A0What I need is something that can tell
the difference between real congestion and radio loss. =A0ECN seems to
be the way forward in that respect.

Yes. When it works. Which is rarely.
=A0

But assuming my network, as a server of content is not over
subscribed, what would you suggest as the best qdisc for such a
traffic profile? In other words, I am looking at this from the server
aspect rather than from the client aspect.


Ah, ok. This was discussed in this loooong thread= :

https://lists.bufferbloat.net/pipermail/bloat/2011-March/000= 272.html

Some form of fair queuing distributes the load to the ultimate end node= s better.

As for which packet scheduler to choose for that? Don'= t know, I'm just trying to get to where we can actually test stuff on t= he edge gateways at this point.
