Proxy-PAR is a minimal version of PAR (PNNI Augmented Routing) that
gives ATM-attached devices the ability to interact with PNNI devices
without the necessity to fully support PAR. Proxy-PAR is designed as a
client/server interaction, of which the client side is much simpler
than the server side to allow fast implementation and deployment. 
 
The purpose of Proxy-PAR is to allow non-ATM devices to use the
flooding mechanisms provided by PNNI for registration and automatic
discovery of services offered by ATM attached devices.  The first
version of PAR primarily addresses protocols available in IPv4. But it
also contains a generic interface to access the flooding of PNNI. In
addition, Proxy-PAR-capable servers provide filtering based on VPN IDs
[1], IP protocols and address prefixes. This enables, for instance,
routers in a certain VPN running OSPF to find OSPF neighbors on the
same subnet. The protocol is built using a registration/query approach
where devices can register their services and query for services and
protocols registered by other clients.
