S.Korea broadband firm sues Netflix after traffic surge

Isn't this a problem with legacy peering agreements in today's internet?
The same thing happened between Netflix, Level3, and Verizon a few years
ago. The legacy concept of settlement-free peering is based on traffic
forwarding parity. If what I forward to you roughly matches what you
forward to me, we can agree that we have no reason to charge each other for
access. The concept works fine when content and eyeballs are evenly
distributed between providers. This doesn't work in today's divergent
content and eyeball networks.

If Netflix agreed to settlement-free peering under the legacy definition,
then as far as the letter of the law goes, Netflix is in the wrong.

SK's in kind of a pickle when it comes to peering regulation, but it looks
like they need 1:1.8 for settlment-free peering.

ATT Peering Policy
Peer must maintain a balanced traffic ratio between its network and AS7018.
In particular:
- No more than 2.0:1.0 ratio of traffic flowing in either direction, on
- Balanced time of day traffic distribution currently as measured by peak
to average traffic levels

Verizon Peering Policy
Traffic Exchange Ratio. The ratio of the aggregate amount of traffic
exchanged between the Requester and the Verizon Business Internet Network
with which it seeks to interconnect shall be roughly balanced and shall not
exceed 1.8:1.

Lumen Peering Policy
The backbone cost burden associated with settlement-free peering traffic
exchange should be equitably shared. Regardless of the direction or type of
traffic exchanged between the networks, the routing practices and location
of interconnection points should be such that each party bears a reasonably
equal share of backbone costs.
