Re: [Micronet] effect of music sharing on shared 10Mb network

Well, the answer is: it depends.

How many folks are generating how many streams, to start with, each
stream being, say 128Kbps or so....
Incomputable due to excessive imponderables. Or, I'm too lazy to go do
the math.

Especially since it's not the real question/answer anyway. Which 10Mbit
network? Some are only lightly used and won't notice, others are
practically vomiting bits out of every port and are screaming for a
upgrade (and you thought it was fan whine).

My educated/experienced guess is that it's not crippling, but it's not
trivial either. If there are throughput issues, i.e. "slow network"
complaints, I'd advise those who are sharing music, and or listening to
Internet radio feeds to knock it off until the network can be upgraded.

As a policy issue, I think it's still "incidental use" for those sharing
music locally, but the Internet radio stuff from off campus is another
question, since it's costing the campus money when they do that, another
little known fact that folks should be aware of.

This will hopefully be less of an issue as time goes on, and a sound
file becomes "small" in the larger scheme of things.
