Routing
FANP
flow attribute
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'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;
(1) soft-state cut-through path (Dedicated-VC) management
(2) protocol between neighbor nodes instead of end-to-end
(3) applicable to any connection oriented datalink platform
