    abstract =  {This document describes how bidirectional flows (biflows) can be implemented in the IP Flow Information Export (IPFIX) protocol. We propose a variety of methods for biflow export, including an extension to the IPFIX Information Model that allows the specification of biflow semantics and a set of counters needed for biflow processing.},
