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. Distribution of this
memo is unlimited.
