Abstract

   In this document, we describe the applicability of the IP Flow
   Information eXport (IPFIX) protocol for a variety of applications.
   We show how applications can use IPFIX, describe the relevant
   Information Elements (IEs) for those applications, and present
   opportunities and limitations of the protocol.  Furthermore, we
   describe relations of the IPFIX framework to other architectures and
   frameworks.
