Figure 3: ATN/IPS ANET Architecture Figure 3: ATN/IPS ANET Architecture
The Client uses an Air-to-Ground (A/G) interface to log into
individual ANETs. The A/G interface specification for the ATN/IPS is
under development in an ancillary document
[I-D.templin-atn-aero-interface].
When a Client logs into an ANET it specifies a nearby s-ASBR that it When a Client logs into an ANET it specifies a nearby s-ASBR that it
has selected to connect to the ATN/IPS. (Selection of a nearby has selected to connect to the ATN/IPS. (Selection of a nearby
s-ASBR could be through consulting a geographically-keyed static host s-ASBR could be through consulting a geographically-keyed static host

The login process is transparently brokered by a Proxy at the border The login process is transparently brokered by a Proxy at the border
of the ANET, which then conveys the connection request to the s-ASBR of the ANET, which then conveys the connection request to the s-ASBR
via tunneling across the SPAN. The s-ASBR then registers the address via tunneling across the SPAN. The s-ASBR then registers the address
of the Proxy as the address for the Client, and the Proxy forwards of the Proxy as the address for the Client, and the Proxy forwards
the s-ASBR's reply to the Client. If the Client connects to multiple the s-ASBR's reply to the Client. If the Client connects to multiple
ANETs, the s-ASBR will register the addresses of all Proxies as ANETs, the s-ASBR will register the addresses of all Proxies as
