The IESG has approved the following document: - 'Link-layer Event Notifications for Detecting Network Attachments ' <draft-ietf-dna-link-information-06.txt> as an Informational RFC This document is the product of the Detecting Network Attachment Working Group. The IESG contact persons are Jari Arkko and Mark Townsley. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-dna-link-information-06.txt Technical Summary Certain network access technologies are capable of providing various link-layer status information to IP. Link-layer event notifications can help IP expeditiously detect configuration changes. This document provides a non-exhaustive catalogue of information available from well-known access technologies. Working Group Summary The dna working group reached consensus on this document on the DNA mailing list. There was strong support for the document from key contributors to the WG and no opposition. One contentious issue in this draft has been whether it should document just Link Up or also Link Down events. Based on reviews from the designer of DNAv4 and the AD review, it was finally decided to focus only on the Link Up event. Protocol Quality This document and has been reviewed by the dna working group and the required changes have been incorporated into the document. The document has also been reviewed by a member of the IAB (Bernard Aboba) and wg chairs of the bridgeand hubmib working groups (Dan Romascanu and David Harrington). Some of the information contained within has been derived from documents reviewed by other standards bodies. A significant amount of review was also received during IETF Last Call, and the suggested changes are either in the -06 version or in the below RFC Editor notes. Note to RFC Editor Please insert a new paragraph between the 2nd and 3rd paragraph of Section 1: OLD: NEW: Link-layer event notifications can help IP expeditiously detect configuration changes. This document provides a non-exhaustive catalog of information available from some access technologies, and discusses the interpretation of this information at the IP layer. This document is not intended to specify or change the behaviour of these access technologies in any manner. Also, please change the following. In Section 3: OLD: notification must be delivered NEW: notification is delivered OLD: notification must be generated and what information must be included in it NEW: notification is generated and what information is included in it Section 3.1: OLD: must generate a link up NEW: generates a link up OLD: notification must be the IPv4 NEW: notification is the IPv4 Section 3.2: OLD: notification must be delivered NEW: notification is delivered OLD: address must be provided NEW: address is provided Section 3.3: OLD: must be generated NEW: is generated OLD: must cause a link up NEW: causes a link up OLD: notification must be generated, if one NEW: notification is generated, if one OLD: notification must be generated.
