BitTorrent's MicroTP (uTP) had about 15% at some point as well. This was
especially scary as:
* it used the then not-fully-understood LEDBAT congestion algorith
This *is* commonly a problem. Look up "TCP incast".
The scenario is exactly as you describe. A distributed database makes
queries over the same switch to K other nodes in order to verify the
integrity of the answer. Data is served from memory and thus access times
are roughly the same on all the K

I have some knowledge in this area which may help. You should be aware that
BitTorrent may use uTP which is a TCP alternative that tries to elimi
I am building a load-constraint system, for Erlang, called safetyvalve[1].
Because this system has a concept of a queue I was wondering on applying
some AQM to this queue and CODEL looks like an interesting one to ponder
about. Especially because the algorithm is wonderfully simple. But is the

My eTorrent uTP branch almost but not quite implement uTP in Erlang.
It uses a LEDBAT classifier in its base, and th
