A new Request for Comments is now available in online RFC libraries. RFC 7471 Title: OSPF Traffic Engineering (TE) Metric Extensions Author: S. Giacalone, D. Ward, J. Drake, A. Atlas, S. Previdi Status: Standards Track Stream: IETF Date: March 2015 Mailbox: spencer.giacalone@gmail.com, dward@cisco.com, jdrake@juniper.net, akatlas@juniper.net, sprevidi@cisco.com Pages: 19 Characters: 38803 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-ospf-te-metric-extensions-11.txt URL: https://www.rfc-editor.org/info/rfc7471 In certain networks, such as, but not limited to, financial information networks (e.g., stock market data providers), network performance information (e.g., link propagation delay) is becoming critical to data path selection. This document describes common extensions to RFC 3630 "Traffic Engineering (TE) Extensions to OSPF Version 2" and RFC 5329 "Traffic Engineering Extensions to OSPF Version 3" to enable network performance information to be distributed in a scalable fashion. The information distributed using OSPF TE Metric Extensions can then be used to make path selection decisions based on network performance. Note that this document only covers the mechanisms by which network performance information is distributed. The mechanisms for measuring network performance information or using that information, once distributed, are outside the scope of this document. This document is a product of the Open Shortest Path First IGP Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
