IS-IS Traffic Engineering Metric Extensions
RFC 7810, “IS-IS Traffic Engineering Metric Extensions”, is a Proposed Standard document published in May 2016 by S. Previdi, S. Giacalone, D. Ward, J. Drake, Q. Wu. It has been obsoleted by RFC 8570 — refer to the newer document for the authoritative version. 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) 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.
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.
