RE: Internet Traffic Discovery?

["Deepak Jain" <deepak () ai net>]

The Bell Labs guys only used "hundreds of gigabytes" of "real" packet data,
which if  I am not mistaken is only a few minutes of traffic on any high
speed link.

The more concerning issue with the article (I found) was that they
"simulated real data". What does this mean? How can you simulate something
you are trying to study without prejudicing your results?

But yes, I think I have heard/seen "macro flows are long lived and stable"
before, but didn't know who to credit it to.

 [ Their surprising discovery - that traffic on heavily loaded,
   high-capacity network links is unexpectedly regular ]

These characteristics had been pointed out by Bill Barns and MO in the
core of a promising local ISP. The phrase used was something like "city
pair macro flows are long lived and stable."  It is good to get some
formal research into this, backing up emperical data.
