 Export BGP community information in IP Flow Information Export (IPFIX)
                draft-ietf-opsawg-ipfix-bgp-community-05

Abstract

   This draft updates RFC7012 IPFIX information model by introducing
   several information elements (IEs) to enable IPFIX to export the BGP
   community information, including BGP standard community defined in
   RFC1997, BGP extended community defined in RFC4360, and BGP large
   community defined in RFC8092.  Network traffic flow information can
   then be accumulated and analysed at the granularity specified by the
   BGP communities, which is suitable for and needed by some traffic
   optimization applications located in IPFIX collector, SDN controller
   or PCE (Path Computation Element).

   To clarify, no new BGP community attribute is defined in this
   document and this document has no purpose to replace BGP Monitoring
   Protocol BMP defined in RFC7854.  The IEs introduced in this document
   are used by IPFIX together with other IEs to facilitate the IPFIX
   collector analyzing the traffic in BGP community granularity without
   running the heavy BGP protocol.
