50% of all traffic we would all have to double our circuit and

I think you're right to say that if thats not acceptable to the
user then usage
based billing should be avoided for them but ultimately they will
the cost as you increase prices over time to foot the cost of increasing
Analogically, imagine if Burger King kept getting shipments of buns that
they didn't want but still had to pay for. Their customers would get pretty
pissed if BK added an 'unwanted bun' charge to their bill (absent specific
prior agreement). I pay for the food I order, not the food BK's suppliers
ship to BK. Of course, it's reasonable for BK to raise their prices for the
costs of having to deal with the unwanted food.
No that wouldnt work, that was be an analogy to non-usage based eg I buy a 10Mb
port from you and you dont charge me extra for unwanted bandwidth across your
I sympathize with the customer. There is no reason he should pay for
traffic he did not request and does not want. If unwanted traffic raises
your cost of providing the service for which you are paid (providing wanted
traffic) then you should raise your rates.
Thats the nature of the Internet which is what you're buying.. you get a
permanent supply of unwanted packets, attacks, spam, viruses etc. If you want to
avoid it dont connect to the Internet.
In principle, one could certainly enter into an agreement where the
customer agrees to bear the costs of unwanted traffic in exchange for a
lower rate. But I certainly wouldn't assume the customer agreed to pay for
traffic he doesn't want and didn't ask for unless the contract explicitly
Most contracts define traffic as the averaged rate across the interface, they
dont look into what that traffic is and whether anyone requested it. In this
sense the comparisons between internet traffic and toll phone calls breaks down,
its also the basis for an argument on settlement free bilateral peering ;p
And for those people entering into contracts, make sure the contract is
clear about what happens with DoS attacks and where the billable traffic is
measured. Otherwise you might be pretty surprised if you get a bill for
250Mbps of traffic when you contracted for a 45Mbps circuit.
Indeed, but most contracts are either 95 percentile or another kind of
smoothed average.. if however it specifies for example you are charged on the
peak 5 minute average in the month you could be in trouble!
For those dealing with contracts already in place, if your provider argues
that you are responsible for all attack traffic no matter what, ask them if
that means you could possibly get billed for 1Gbps of traffic even though
you only bought a T1.
Presumably as the measurement is on the rate across the interface this couldnt
