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). These extensions provide a way to distribute
and collect network-performance information 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 obsoletes RFC 7810.
This document is a product of the Link State Routing 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.
