1. Overview: Internet Protocol Flow
Information eXport (IPFIX)
Internet Protocol Flow Information eXport (IPFIX) has evolved as an improvement upon the
Netflow V9 protocol. It is a standard that has been proposed by an IETF Working Group -
http://www.ietf.org/html.charters/ipfix-charter.html. IPFIX is an effort to standardize on
architecture for IP flow measurement and export. In an IPFIX model, an exporter such as a switch
or router collects IP flows and then exports the IP flow information using a transport protocol to a
collection server or servers. An IP flow is defined as a set of packets over a period of time that
has some common properties.
