MPLS Upstream Label Assignment and Context-Specific Label Space
RFC 5331, “MPLS Upstream Label Assignment and Context-Specific Label Space”, is a Proposed Standard document published in August 2008 by R. Aggarwal, Y. Rekhter, E. Rosen. It has since been updated by RFC 7274. The canonical text is published by the RFC Editor.
Abstract
RFC 3031 limits the MPLS architecture to downstream-assigned MPLS labels. This document introduces the notion of upstream-assigned MPLS labels. It describes the procedures for upstream MPLS label assignment and introduces the concept of a "Context-Specific Label Space". [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.
