<abstract>
<t>
   This memo discusses Flow Attribute Notification Protocol (FANP),
   which is a protocol between neighbor nodes for the management of
   cut-through packet forwarding functionalities. In cut-through packet
   forwarding, a router doesn&apos;t have to perform conventional IP packet
   processing for received packets.  FANP indicates mapping information
   between a datalink connection and a packet flow to the neighbor node
   and helps a pair of nodes manage the mapping information.  By using
   FANP, routers (e.g., CSR; Cell Switch Router) can forward incoming
   packets based on their datalink-level connection identifiers,
   bypassing usual IP packet processing.  The design policy of the FANP
   is;

<list>
<t>
       (1)  soft-state cut-through path (Dedicated-VC) management
</t>
<t>
       (2)  protocol between neighbor nodes instead of end-to-end
</t>
<t>
       (3)  applicable to any connection oriented datalink platform
