Status of this Memo

   This document provides information for the Internet community.  This
   memo does not specify an Internet standard of any kind.  Distribution

IESG Note:

   This memo documents a private protocol for IPv4-based flows.  This
   protocol is NOT the product of an IETF working group nor is it a
   standards track document.  It has not necessarily benefited from the
   widespread and in depth community review that standards track
   documents receive.

Abstract

   The Ipsilon Flow Management Protocol (IFMP), is a protocol for
   allowing a node to instruct an adjacent node to attach a layer 2
   label to a specified IP flow.  The label allows more efficient access
   to cached routing information for that flow.  The label can also
   enable a node to switch further packets belonging to the specified
   flow at layer 2 rather than forwarding them at layer 3.
