This document describes an efficient method for exporting bidirectional flow (Biflow) information using the IP Flow Information Export (IPFIX) protocol, representing each Biflow using a single Flow Record. It proposes two alternatives for information model extensions to support this method, for the consideration of the IPFIX Working Group.
