The Use of Entropy Labels in MPLS Forwarding
RFC 6790, “The Use of Entropy Labels in MPLS Forwarding”, is a Proposed Standard document published in November 2012 by K. Kompella, J. Drake, S. Amante, W. Henderickx, L. Yong. It updates RFC 3031, RFC 3107, RFC 3209, RFC 5036. It has since been updated by RFC 7274, RFC 7447, RFC 8012. The canonical text is published by the RFC Editor.
Abstract
Load balancing is a powerful tool for engineering traffic across a network. This memo suggests ways of improving load balancing across MPLS networks using the concept of "entropy labels". It defines the concept, describes why entropy labels are useful, enumerates properties of entropy labels that allow maximal benefit, and shows how they can be signaled and used for various applications. This document updates RFCs 3031, 3107, 3209, and 5036. [STANDARDS-TRACK]
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.
