RFC 3443: Time To Live (TTL) Processing in Multi-Protocol Label Switching (MPLS) Networks

Still current, but amended. Parts of this document are changed or extended by RFC 5462. Read both.

In plain English — editorial summary, not part of the RFC

This document describes Time To Live (TTL) processing in hierarchical Multi-Protocol Label Switching (MPLS) networks and is motivated by the need to formalize a TTL-transparent mode of operation for an MPLS label-switched path. It updates RFC 3032, "MPLS Label Stack Encoding". TTL processing in both Pipe and Uniform Model hierarchical tunnels are specified with examples for both "push" and "pop" cases. The document also complements RFC 3270, "MPLS Support of Differentiated Services" and ties together the terminology introduced in that document with TTL processing in hierarchical MPLS networks.
