In certain networks, such as, but not limited to, financial
information networks (e.g., stock market data providers), network-
performance criteria (e.g., latency) are becoming as critical to
data-path selection as other metrics.
This document describes extensions to IS-IS Traffic Engineering
Extensions (RFC 5305) such that network-performance information can
be distributed and collected in a scalable fashion. The information
distributed using IS-IS TE Metric Extensions can then be used to make
path-selection decisions based on network performance.
Note that this document only covers the mechanisms with which
network-performance information is distributed. The mechanisms for
measuring network performance or acting on that information, once
distributed, are outside the scope of this document.
This document is a product of the IS-IS for IP Internets 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.
