IS-IS Traffic Engineering Metric Extensions
RFC 8570, “IS-IS Traffic Engineering Metric Extensions”, is a Proposed Standard document published in March 2019 by L. Ginsberg, S. Previdi, S. Giacalone, D. Ward, J. Drake, Q. Wu. It obsoletes RFC 7810. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
