I was wondering if any NSP or NAP still supports the requirement
to carry OSI/CLNP traffic.
NAPs can be proposed to be implemented as LANs or MANs or
other innovative approaches. NAPs must operate at speeds
commensurate with the speeds of attached networks and
must be upgradable as required by demand, usage, and
Program goals. NAPs must support the switching of IP
(Internet Protocol) and CLNP (ConnectionLess Networking
Protocol) packets
I think this is a legacy, aka obsolete, requirement. But some
folks with checklists insist you can't be a NSP or NAP if you
don't support it.
