Segment Routing with the MPLS Data Plane
RFC 8660, “Segment Routing with the MPLS Data Plane”, is a Proposed Standard document published in December 2019 by A. Bashandy, C. Filsfils, S. Previdi, B. Decraene, S. Litkowski, R. Shakir. The canonical text is published by the RFC Editor.
Abstract
Segment Routing (SR) leverages the source-routing paradigm. A node steers a packet through a controlled set of instructions, called segments, by prepending the packet with an SR header. In the MPLS data plane, the SR header is instantiated through a label stack. This document specifies the forwarding behavior to allow instantiating SR over the MPLS data plane (SR-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.
