It all started when CS departments decided they didn't need EE courses or
affiliation with EE depts., and continued with the idea that digital
communications had nothing to do with the folks who design the gear, so all you
needed to know was the bit layouts of packets in memory to be a "network
In short, people who build hardware devices, or device drivers, don't
understand TCP.
There is a first class education failure in all this.
We have yet to find almost any device that isn't bloated; the only question
is how badly.

At least someone actually saw what I've been seeing for years now in Metro area
HSPA and LTE deployments.
As you know, when I first reported this on the e2e list I was told it could not
possibly be happening and that I didn't know what I was talking about. No one
in the phone companies was e
I've got a bit more insight into LTE than I did in the past, courtesy of
the last couple days.
To begin with, LTE runs with several classes of service (the call them
bearers). Your VOIP traffic goes into one of them.
And I think there is another as well that is for guaranteed bit rate
traffic. O

No, it just measures delay. Since so far as I know the outgoing portion of
LTE is not soft-rate limited, but sensitive to the actual available link
bandwidth, fq_codel should work pretty good (if the
Doesn't fq_codel need an estimate of link capacity? Where will it get that
from the 4G or 3G uplink?

A small suggestion. Instead of working on *algorithms*, focus on getting
something actually *deployed* to fix the very real issues that we have today
(preserving the option to upgrade later if need be).
The folks who built the Internet (I was there, as you probably know) focused on

Hiya,
Looks like Google's experimenting with 3.8 for Android:
https://android.googlesource.com/kernel/common/+/experimental/android-3.8
Sounds great if this means they will utilize fq_codel, TFO, BQL, etc.
Anyway my nexus 7 says it has 3.1.10 and this 3.8 will probably go to
Android 5.0 so I hope
