Yes, Above.Net broke the original peering-ratio fight that way.  Thank =
you for that.  Too bad it didn't last.

There are many broken parts of 'modern' peering agreements.

"You must spend as much on your backbone as I spend on mine."  "You must =
be on at least 3 continents (no matter where the traffic goes to or =
from)."  "'Peer' means 'equal'."  "You have to be wearing a blue hat =
when you request peering."  Whatever.

I've said it before, more times than I can count.  Peering is a business =
tool, a means to an end.  The goal, the 'end', of for-profit companies =
is to make a profit.  Sounds obvious, but surprising how many people =
forget this.  If peering with another network will increase your profit =
and you turn down the peering request, you should be fired.  Your ego =
should not be substituted for business decisions.

Some people rationalize these decisions (read: "con themselves into =
believing") by saying if they do not peer with a network, they will gain =
revenue from that network.  It even works sometimes.  Most of the time =
it does not work, and in more & more cases ensures no revenue will =
-ever- flow between the companies.

Just so no one jumps all over me, I am not even hinting that peering =
requests must always be accepted.  There are rational, business reasons =
to turn down peering.  But a one-size-fits-all policy is idiotic, as are =
most of the reasons peering requests are denied these days.


More importantly, the real issue is power (leverage, whatever you want =
to call it).  In the 90s, all users had to do to switch ISPs is change a =
few digits in their modem dialer.  Content owners had to do quite a bit =
more to move a web site between hosting providers.

These days, it is very difficult for end users to change broadband ISPs, =
frequently requiring equipment changes (e.g. DSL -> Cable), moving phone =
& TV, etc.  Worse, for many people in the US, they have only one =
provider who can give them more than 1.5 Mbps.[*]  Content owners can =
move hosting companies easily.

Not hard to figure out who had more power in the 90s, and who has it =
now.

Having a metric sr. mgmt can understand will not change which company =
has power.  Companies that have power -will- exercise it to make money.

L3 is on the wrong side of the power equation today, so they are trying =
to move the discussion to something that has real business logic.  Their =
only hope of the leverage some other companies have is to either get the =
gov't to step in (EWW!), or pray the threat of gov't regulation will be =
enough.  Dangerous game, if you ask me.

[*] Anyone know what %-age of North American users have multiple choices =
for real broadband (e.g. > 1.5 Mbps, or even > 4 Mbps as the FCC now =
defines it)?  I searched, but can't find it.  I can find how many people =
have > 4 Mbps available, but not more than one choice.
