The IESG has approved the following document: - 'Residence Time Measurement in MPLS network' (draft-ietf-mpls-residence-time-15.txt) as Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-mpls-residence-time/ Technical Summary This document specifies a new Generic Associated Channel for Residence Time Measurement and describes how it can be used by time synchronization protocols within a MPLS domain. Residence time is the variable part of propagation delay of timing and synchronization messages and knowing what this delay is for each message allows for a more accurate determination of the delay to be taken into account in applying the value included in a Precision Time Protocol event message. Working Group Summary The working group processing of this group was fairly smooth, experts in the area have ben chiming in and very much improved the document. There has been a high degree of collaboration between members of the MPLS, TICTOC and BMWG Working Groups. There are currently 6 co- authors listed on the front page. This was discussed (chairs, shepherd, AD and authors), we said that considering the level of contribution from different sources, we agreed that it is motivated to have all 6 authors listed on the front page. Document Quality We are aware of intentions to implement this specification, an Implementation Poll has been started and the Write-Up will be added as new information is available. Personnel Who is the Document Shepherd for this document? Loa Andersson Who is the Responsible Area Director? Deborah Brungard
