From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: RFC Editor <email@example.com>, ospf mailing list <firstname.lastname@example.org>, ospf chair <email@example.com> Subject: Protocol Action: 'OSPF Traffic Engineering (TE) Metric Extensions' to Proposed Standard (draft-ietf-ospf-te-metric-extensions-11.txt) The IESG has approved the following document: - 'OSPF Traffic Engineering (TE) Metric Extensions' (draft-ietf-ospf-te-metric-extensions-11.txt) as Proposed Standard This document is the product of the Open Shortest Path First IGP Working Group.

Technical Summary This document specifies extensions to OSPF Traffic Engineering to include delay, loss, and current bandwidth utilization metric that can be taken into account when performing traffic engineering. Working Group Summary: There has been much discussion as to how these metrics would be collected and how they will be used. These topics were deemed to to be out of scope. There was also concern for potential overhead of collecting and flooding these metrics. In response, the draft contains guidance as to how often the measurements should be collected and flooded. Additionally, the draft now recommends configuration to control measurement usage and the thresholds for advertisement. Finally, the draft was updated to include applicability to Advanced Multipath links. It should be noted that, consistent with the long-held IESG policy, there is a partner I-D for extensions to IS-IS (draft-ietf-isis-te-metric-extensions) Document Quality: This document has been a WG document for a little under two years. It is stable, without changes to the technical solution for more than six months. IETF last call was drawn to the attention of the TEAS, CCAMP, and MPLS working groups. Personnel: Acee Lindem is the Document Shepherd. Adrian Farrel is the Responsible Area Director.
