Residence Time Measurement in MPLS Networks
RFC 8169, “Residence Time Measurement in MPLS Networks”, is a Proposed Standard document published in May 2017 by G. Mirsky, S. Ruffini, E. Gray, J. Drake, S. Bryant, A. Vainshtein. The canonical text is published by the RFC Editor.
Abstract
This document specifies a new Generic Associated Channel (G-ACh) for Residence Time Measurement (RTM) and describes how it can be used by time synchronization protocols within an MPLS domain.
Residence time is the variable part of the propagation delay of timing and synchronization messages; knowing this delay for each message allows for a more accurate determination of the delay to be taken into account when applying the value included in a Precision Time Protocol event message.
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.
