basic model of data and money flows from the small ISP's perspective
in Australia is this (keep in mind this represents volume charges,
not rentals or other static fees).
Internet user pays money to an ISP to get data. The ISP has to pay
money to a owner of a backbone network to get that data from wherever
else on the Internet it is stored.
you should notice is that where the backbone owner gets the data
from another small ISP, they don't have to pay for it. Where ISPs
are providing much more data than they download, the major backbone
operator in Australia, Telstra, even charges the ISP for the privilege
(this is the so-called "backchannel policy").
cut costs, the ISPs have tried to cut out the middleman.

the theory. In practice, AUSIX does charge flat fees for its service,
and you have to figure out whether you can save enough money on
data charges to cover your AUSIX fees. Now, there are many extra
benefits you get from AUSIX membership, as will be detailed further
on, but of course you want to know whether peering is going to be
worthwhile for you.
it must be said that there are certain types of ISPs which will
not be able to justify joining AUSIX. Very small providers may
not be able to afford the fees. ISPs who take all their data on
a flat rate will also find it hard to find cost savings. Companies
who do mainly hosting, and have very few dial-up users, will not
be able to figure out a profitable arrangement if they look at it
purely in terms of transit savings (there are other reasons you
that said, let's get down to the basics.
are three types of traffic you would take from your AUSIX connection:
content hosted by AUSIX members, NNTP news feeds, and shared proxy
amount of content hosted by AUSIX members is very substantial -
a survey of members showed that outgoing traffic from their hosted
sites totals more than 35 terabytes per month. In addition, AUSIX
is talking to several hosting companies and content providers, some
of which host sites which are in the top ten most popular in Australia,
to add their content to the AUSIX network. For the purposes of working
out how much you could save, the consensus estimate on the average
ratio of local to international downloaded traffic by Australian
Internet users is about 30:70. Of that 30% local downloads, AUSIX
would represent a small fraction, but a significant one.
traffic is currently provided by our members, but AUSIX is also
talking with several providers of multicast satellite feeds, not
only for news feeds but also broadband content like streaming video.
Being in close proximity on AUSIX racks to many other ISPs, our
members have worked out many deals between themselves to peer the
contents of their cache servers. Instead of relying on your own
box, you could be connecting through AUSIX create a virtual proxy
with four times the capacity of your present server. There may also
be a centrally hosted AUSIX cache server in the future provided
by Hitwise, which will generate revenue for connecting members.
