The current method should probably be: locate where the packet loss
occurs, forward it to your provider, your provider forwards it to his,
and so on.
Yes, there is no formal mechanism to my knowledge, but should we really
make one?
If we start to formalize then we have later to formalize the meetpoint
relationships (who is responsible for packet loss on a meetpoint network?).
A better point of pressure: chose a provider with shorter internal paths.
On the Internet anyone can kick the tires of any network by sending
probing data accross it. You get latency, hop count, and throughput of
the smallest link in your path.
The job to find this out is a consultant's job. The consultant knows
about the Internet topology, and how to quickly find out if a provider
will be ok for the wanted connectivity, or not.
Scopes of connectivity can be global reachability (trading off maybe
hopcounts and comparing on offered routes and latency), short paths (for
virtual private networks or national connectivity), points of presence in
your business locations.
If everyone would chose, then the now big networks, that offer an
impressive display of capital investment (called excessive hopcount by
some people with negative attitude ;-) ), will probably redisign their
routing (or why do some connections backtrack via both coasts and then to
the next metropole 200 miles away?).
I would say, that market pressure is the best regulatory agent: pinches
directly into the providers pocketbook. I accept this and design for
customers, and have customer needs and quality issues in mind when the
network grows (which it does currently tremendously).
Instead of organizational reglementation, I would put the current path of
Internet routing forward: with current tools it is possible to include
routing decisions of networks around a provider in that providers routing
topology. It is just a matter of time to implement it.
