Entropy Label for Source Packet Routing in Networking Tunnels
RFC 8662, “Entropy Label for Source Packet Routing in Networking Tunnels”, is a Proposed Standard document published in December 2019 by S. Kini, K. Kompella, S. Sivabalan, S. Litkowski, R. Shakir, J. Tantsura. The canonical text is published by the RFC Editor.
Abstract
Segment Routing (SR) leverages the source-routing paradigm. A node steers a packet through an ordered list of instructions, called segments. Segment Routing can be applied to the Multiprotocol Label Switching (MPLS) data plane. Entropy labels (ELs) are used in MPLS to improve load-balancing. This document examines and describes how ELs are to be applied to Segment Routing MPLS.
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.
