The IESG has approved the following document: - 'Information Elements for Data Link Layer Traffic Measurement' (draft-ietf-ipfix-data-link-layer-monitoring-08.txt) as Proposed Standard This document is the product of the IP Flow Information Export Working Group. The IESG contact persons are Benoit Claise and Joel Jaeggli. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-ipfix-data-link-layer-monitoring/ Technical Summary This document describes Information Elements (IEs) related to data link layer. They are used by the IP Flow Information Export (IPFIX) protocol for encoding measured data link layer traffic information. The document is intended to be a Proposed Standard. It describes, in detail, a set of Information Elements describing link-layer objects. These will be particularly to service providers who use Wide-Area Ethernet or Virtual Ethernet technologies. Working Group Summary This draft's -00 version was published in July 2012. Two of its authors were from a large Japanese provider who needed to monitor and report on link-layer performance. Since then it has received ongoing low-activity-level discussion on the IPFIX list. It has also been discussed at each IETF meeting since then; alas, the WG has always considered this as low-priority work. Document Quality Its WGLC was run in October 2012; we realised at that point that we needed someone from IEEE 802.1 to check that our Ethernet IEs were correct in their descriptions of the IEEE-defined technologies. Pat Thaler, IEEE liaison for IETF, has helped develop this document since then, she confirms that the IEEE-related IEs are correct in their descriptions. It has been carefully reviewed by Paul Aitken and Brian Trammell, both pointed out issues; these have been addressed in successive versions. Overall I believe that there is clear consensus within the WG for this draft. Personnel Document shepherd: Nevil Brownlee Responsible Area Director: Benoit Claise 'The IANA Expert(s) for the registries in this document are the IPFIX Information Element (IE) doctors ( ie-doctors@ietf.org ). The IPFIX IE doctors reviewed and approved the IEs in this document.
