I disagree with this last part.
I realize that the common wisdom among execs at so-called tier-1 =
providers
is that refusing SFI protects their revenue stream, but I believe it=E2=80=
=99s not
true.
In fact, I think that a willingness to peer with your customers and =
anyone
else on the internet wherever you can do so for very little cost (for =
example,
where it=E2=80=99s just one more peering session at an IXP, no =
additional port cost,
circuit, XC, etc.) settlement free can only increase your business.
IMHO, a truly good tier-1 will charge for transit, set their metrics and
prefs such that their paid ports are preferred over their non-revenue
ports, and provides peer routes only on the SFIs.
This turns out to be mostly a win-win situation for everyone, including =
the
tier-1 in the long run.
OTOH, look what happened to SPRINT when they went on their depeering =
binge.
They went from the cat-bird seat of being the top Tier-1 provider on the
planet to the modern day status of =E2=80=9Calso ran=E2=80=9D.
I suspect the only reason Cogent isn=E2=80=99t losing ground as fast as =
SPRINT
did has to do with two things:
1. They aren=E2=80=99t turning off existing peers as aggressively =
as
SPRINT did.
2. They have the cheapest transit prices of just about anyone
except possibly HE (why they are in a race to the bottom with).
However, even at their current rate, this will likely catch up with them
sooner or later and cause them some discomfort.
YMMV.
