OK, how about this...
The core of the US Internet, also known as the default-free core, no longer
follows a backbone topology. The core is composed of the major NSP's who
operate national backbones providing national transit and who interconnect
at all or most of the public exchange points.
So, to determine whether a carrier is part of the core:
Are they an NSP?
Do they operate their own national backbone?
Can they provide national transit over their own network infrastructure?
Do they interconnect with other NSP's who satisfy the previous two
conditions at most of the public exchange points?
Is this better?
