Good point :-) I've just heard that number, but don't have a source to back
it up.
Any odd number needs a study or two to back it up ...

I think it's reasonably safe to call the bluff on that statistic.
Probably well upwards of 30% of all TCP traffic is HTTP these days*, and
last time I checked Apache accounts for around 62.52% of all web
servers, Microsoft products another 30.13%, together around 93%**.  Just
from looking at the rough numbers there, even if I'm high balling the
HTTP numbers (probably not by much, if at all), then that's 25%+ that
isn't touching a main frame at all.  The traffic goes straight from a
client, likely through some appliance NAT router of theirs, into a cable
or DSL modem, through an access device at the other end onto Ethernet,
through a crap-load of routers, and eventually to a switch and some
random unix/ms server*** on the other end, and back again.  Another
interesting argument is that I've seen a lot of reports lately that p2p
traffic is consuming crazy percentages of all internet traffic these
days, some say as high as 60 to 75%.  I think those are exagerated
numbers, but I'd believe 40% or more.  I am not even aware of any p2p
apps for OS360, or anything even resembling a mainframe.  :)

trustworthy statistics here.

*** - Don't even try the "these are virtual instances on z-series
mainframes" angle, no way there's any sizable percentage of websites on
such a platform, see Netcraft again.
