Is it mandatory for all ISPs in the country to connect to NIXI?

It is a highly unusual model for IXPs in that it mandates "forced
regional peering" AND acts as a settlement house.

What "requester pays" means in this case is that " "requested" traffic
from ISP A to ISP B is measured and subtract the "requested" traffic
from ISP B to ISP A."

In other words in the case of asymmetric traffic flows, one provider
pays another.  This is not unusual, but what is unusual is that such
asymmetries are normally monitored by each party and if it continues
for months on end, then either depeering occurs or one network will
ask for the other to pay them (paid peering or transit).

In any case, the NIXI model would make it trivial for one ISP (or a
cyber criminal) to create such an assymetry.

I wrote about such a scenario in the context of "sending party network pays"

I don't see how this is any different in potential outcome.

Best to let bodies make agreements amongst themselves.  That's what
has worked remarkably well so far.
