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.
Working Group Summary
This bis draft update to RFC7810 was created out of an errata
submitted that pointed out errors in the definition of certain
bandwidth related sub-TLVs. There was a quick and unanimous
decision to address this error by publishing this bis update.
The specific changes are outlined in the Appendix.
The RFC7810 published over two years ago has at least two known
implementations. There is no change to the technical solution
in this update. The updated bis draft has identical content
to RFC7810 except for the changes for fixing of the error
in encoding and highlighting the changes in the appendix.
Ketan Talaulikar is the Document Shepherd.
Alvaro Retana is the Responsible Area Director.
