Transition is Underway

What does this mean

NAPs - Network Access Points

NAPs are for NSP to NSP Interconnectivity and Interoperability (NNI).

US R&E community that is covered by RNP funding will be made available at the NAPs to all others.

Good place for working on interconnectivity and interoperability.

Located in:

Routing Arbiter will locate Route Servers at the NAPs.

Routing Arbiter

Awards to ISI+IBM and Merit.

Is both a technology and an operational project. (Learn by doing)

Register and disseminate Internet routing and addressing information.

Parallel/cooperative efforts by Europeans (RIPE), CANet, and Asian Pacific (APEPG).

Development/evolution of routing system for the Internet. (provider selection, navigation of Internet mesh, IP to ATM mapping, resource management, multicast, routing configuration and stability, etc.)

Route servers at NAPs

Recognize distributed nature of the Internet (RA is not a "central control" function).
