Color is a 32-bit numerical (unsigned integer) attribute used to
associate a Traffic Engineering (TE) tunnel or policy with an intent
or objective. For example, a TE Tunnel constructed to deliver low
latency services and whose path is optimized for delay can be tagged
with a color that represents "low latency." This document specifies
extensions to the Path Computation Element Protocol (PCEP) to carry
the color attribute.
This document is a product of the Path Computation Element 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
