[Bloat] Network computing article on bloat

[Constantine Dovrolis]

Thanks Wes - I was hoping that someone will make this point.

btw, another common reason for lossless operation is the
size of the flows. basically flows often finish before their
window increases so much that they overflow their bottleneck's
buffer.

Plz spend some time to read the following paper:
http://www.cc.gatech.edu/fac/Constantinos.Dovrolis/Papers/buffers-ton.pdf
It is very relevant to the bufferbloat initiative and it shows clearly,
I think, that statements like "Big Buffers Bad. Small Buffers Good."
are crude oversimplifications that will cause even more confusion.

regards

Constantine
