The IESG has approved the following document: - 'Information Model for IP Flow Information eXport (IPFIX)' (draft-ietf-ipfix-information-model-rfc5102bis-10.txt) as Proposed Standard This document is the product of the IP Flow Information Export Working Group. The IESG contact persons are Ronald Bonica and Benoit Claise. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ipfix-information-model-rfc5102bis/ Technical Summary: This document provides an overview of the information model for the IP Flow Information eXport (IPFIX) protocol, as defined in the IANA IPFIX Information Element Registry. It is used by the IPFIX Protocol for encoding measured traffic information and information related to the traffic Observation Point, the traffic Metering Process, and the Exporting Process. Although developed for the IPFIX Protocol, the model is defined in an open way that easily allows using it in other protocols, interfaces, and applications. This document obsoletes RFC 5102. Working Group Summary: The documents has been significantly changed in content compared to RFC 5202. The main reason for the change is the existence of an IANA registry for IPFIX information elements. This change was fully aggreed on in WG discussions.

Changes compared to RFC 5102 result from these experiences. Personnel: Who is the Document Shepherd? Who is the Responsible Area Director? Juergen Quittek is the document shepherd.
