As required by RFC 4858, this is the current template for the Document
Shepherd Write-Up.
Changes are expected over time. This version is dated 24 February 2012.
(1) What type of RFC is being requested (BCP, Proposed Standard,
Internet Standard, Informational, Experimental, or Historic)? Why
is this the proper type of RFC? Is this type of RFC indicated in the
title page header?
The OAM procedures need to be standardised for interoperability, so the
specification is on Standards Track as indicated on the title page.
(2) The IESG approval announcement includes a Document Announcement
Write-Up. Please provide such a Document Announcement Write-Up. Recent
examples can be found in the "Action" announcements for approved
documents. The approval announcement contains the following sections:
Technical Summary
This document specifies the Performance Measurement (PM) with Marking Method in
Bit Index Explicit Replication (BIER) Layer(RFC-8279). This document defines
how marking method can be used on BIER layer to measure packet loss and delay
metrics of a multicast flow in MPLS network. The two bit OAM field specified in
BIER header as per RFC-8296 is used for the marking performance measurement.
The method described is a hybrid model and can be used either in single mark or
double mark enabled mode.
Working Group Summary
The document went through few rounds of reviews, comments and revisions and
there is consensus in the WG to publish these documents.

(6) Describe any specific concerns or issues that the Document Shepherd
has with this document that the Responsible Area Director and/or the
IESG should be aware of? For example, perhaps he or she is uncomfortable
with certain parts of the document, or has concerns whether there really
is a need for it. In any event, if the WG has discussed those issues and
has indicated that it still wishes to advance the document, detail those

The document went through few rounds of reviews, comments and revisions and
there is consensus in the WG to publish these documents.
(10) Has anyone threatened an appeal or otherwise indicated extreme
discontent? If so, please summarise the areas of conflict in separate
email messages to the Responsible Area Director. (It should be in a
separate email because this questionnaire is publicly available.)
No appeals.
(11) Identify any ID nits the Document Shepherd has found in this
document. (See https://www.ietf.org/tools/idnits/ and the Internet-Drafts
Checklist). Boilerplate checks are not enough; this check needs to be
thorough.
No nits found.
(12) Describe how the document meets any required formal review
criteria, such as the MIB Doctor, media type, and URI type reviews.
No formal review required.
(13) Have all references within this document been identified as
either normative or informative?
All references correctly documented.

advancement or are otherwise in an unclear state? If such normative
references exist, what is the plan for their completion?
All normative references are existing RFCs.

If so, list these downward references to support the Area Director in
the Last Call procedure.
No downward references that I found.
(16) Will publication of this document change the status of any
existing RFCs? Are those RFCs listed on the title page header, listed
in the abstract, and discussed in the introduction? If the RFCs are not

identified. Confirm that newly created IANA registries include a
detailed specification of the initial contents for the registry, that
allocations procedures for future registrations are defined, and a
reasonable name for the new registry has been suggested (see RFC 5226).
The OAM field requirement for the BIER header is captured in IANA
considerations section.
(18) List any new IANA registries that require Expert Review for future
allocations. Provide any public guidance that the IESG would find
useful in selecting the IANA Experts for these new registries.
As per Shepherds understanding, no expert level review is required.

Shepherd to validate sections of the document written in a formal
