3) <!--[rfced] Does "conducting RFC 9097 and other related measurements"
mean "conducting measurements as described in RFC 9097 and other
related measurements"? Please let us know how we may update for
clarity.

Original:
   This document defines the UDP Speed Test Protocol (UDPSTP) for
   conducting RFC 9097 and other related measurements.

Perhaps:

4) <!-- [rfced] We are unsure if the quoted text was intended to be the
titles of or concepts in the RFCs listed. Since quote marks were
present, we updated the text to reflect the exact titles of the
RFCs. Please let us know if this is agreeable or if you prefer
otherwise.

Original:
   The performance community has seen development of Informative Bulk
   Transport Capacity definitions in the "Framework for Bulk Transport
   Capacity" (BTC, see [RFC3148]) and for "Network Capacity and Maximum
   IP-layer Capacity" [RFC5136]. "Model-Based Metrics for BTC" add
   experimental metric definitions and methods in [RFC8337].

Current:
   The performance community has seen the development of Informative
   Bulk Transport Capacity (BTC) definitions in "A Framework for
   Defining Empirical Bulk Transfer Capacity Metrics" [RFC3148] and
   "Defining Network Capacity" [RFC5136] as well as experimental
   metric definitions and methods in "Model-Based Metrics for Bulk
   Transport Capacity" [RFC8337].

5) <!--[rfced] FYI - We made "LMAP environments" singular to agree with
"another independent third-party domain measurement server
deployment" as shown below. Please let us know of any objections.

Original:
   UDPSTP may be deployed in Large-Scale Measurement of Broadband
   Performance environments (LMAP, see [RFC7497]), another independent
   3rd party domain measurement server deployment.

Current:
   UDPSTP may be deployed in a Large-scale Measurement of Broadband
   Performance (LMAP) environment (see [RFC7497]), another independent
   third-party domain measurement server deployment.

6) <!--[rfced] Please clarify "benefit from trust into the results". Is
the intended meaning perhaps "benefit from trusting the results"?

Original:
   All these deployments require or benefit from trust into the
   results, which are ensured by authenticated communication.

Perhaps:
   All these deployments require or benefit from trusting the
   results, which are ensured by authenticated communication.
-->


7) <!--[rfced] We don't see the terms "mcIndex", "mcCount", and "mcIdent" in
Section 6.1. Was Section 5.1 perhaps intended?

Original:
   Fields in the Setup Request (mcIndex, mcCount, and mcIdent, see
   Section 6.1) are used to both differentiate and associate the
   multiple connections that comprise a single test.

Perhaps:
   Fields in the Setup Request (i.e., mcIndex, mcCount, and mcIdent;
   see Section 5.1) are used to both differentiate and associate the
   multiple connections that comprise a single test.

8) <!--[rfced] Is there only one optional checksum or would it be correct
to make checksum plural in the title of Section 4 (for
consistency with "Requirements" and "Security Operations") as well
as in one sentence in Section 4?

Original:
   Section 4.  Requirements, Security Operations, and Optional Checksum 

   This section adds the operational specification related to security
   and optional checksum.

Perhaps:
   Section 4.  Requirements, Security Operations, and Optional Checksums

   This section adds the operational specification related to security
   and optional checksums.

9) <!--[rfced] In order to avoid hyphenating "Layer-3-to-Layer-4 mapping",
may we rephrase this sentence as shown below?

Original:
   Due to the additional complexities, and loss of the direct
   Layer 3 to Layer 4 mapping of packets to datagrams, it is
   recommended that Layer 3 fragmentation be avoided.

Perhaps:
   Due to the additional complexities, and loss of the direct 
   mapping of packets to datagrams between Layer 3 and Layer 4, 
   it is recommended that Layer 3 fragmentation be avoided.
-->


10) <!--[rfced] We are having trouble parsing this sentence. Please
clarify where the feedback received by the experts and the
changes resulting from standardization were included - was it in
the measurement method or testing?

Original:
   Feedback received by performance measurement experts was included,
   as well as changes resulting from the standardisation of [RFC9097]
   (reflected also in algorithm B [Y.1540Amd2], which updates a prior
   version of this algorithm).
-->


11) <!--[rfced] For clarity, may we update this sentence to contain a
serial list of the threshold values as shown below?

Original:
   The RECOMMENDED threshold values are 10 for sequence number gaps
   and 30 ms for lower and 90 ms for upper delay variation thresholds,
   respectively.

Perhaps: 
   The RECOMMENDED threshold values are 10 for sequence number gaps,
   30 ms for lower delay variation thresholds, and 90 ms for upper
   delay variation thresholds.
-->


12) <!--[rfced] Should this sentence be updated to more closely match
similar wording in Section 3.1? This would also help with how
"avoid activating the measurement" relates to the sentence.

Current:
   If a network operator is certain of the IP-Layer Capacity to be
   validated, then testing MAY start with a fixed-rate test at the
   IP-Layer Capacity and avoid activating the measurement load rate
   adjustment algorithm (see Section 8.1 of [RFC9097])

Perhaps:
   A network operator who is certain of the IP-Layer Capacity to be
   validated MAY start with a fixed-rate test at the IP-Layer Capacity
   and avoid activating the measurement load rate adjustment algorithm
   (see Section 8.1 of [RFC9097])
-->         


13) <!--[rfced] Should "SHOULD" be added to the latter part of this
sentence for clarity (i.e., "SHOULD NOT continue with the Control
phase and SHOULD implement silent rejection")?

Original:
   If the validation fails, the receiver SHOULD NOT continue with the
   Control phase and implement silent rejection (no further packets
   sent on the address/port pairs). 

Perhaps:
   If the validation fails, the receiver SHOULD NOT continue with the
   Control phase and SHOULD implement silent rejection (no further 
   packets sent on the address/port pairs). 
-->


14) <!--[rfced] We note a variance with the terms listed in Section 4.4
versus the terms listed in RFC 7210. In RFC 7210, "Time" is uppercase
(except in "SendLifetimeStart", which contains a lowercase "t"
both in this document and RFC 7210). Should this document be
updated as follows for consistency with RFC 7210?

Original:
   *  SendLifetimeEnd

   *  AcceptLifetimeStart

   *  AcceptLifetimeEnd

Perhaps:
   *  SendLifeTimeEnd

   *  AcceptLifeTimeStart

   *  AcceptLifeTimeEnd

15) <!--[rfced] Does "that 4-tuple" refer to the source and destination
addresses and port numbers? If so, may we update the text as
shown below for clarity?

Original: 
   Successful interaction with a local firewall assumes the firewall is
   configured to allow a host to open a bidirectional connection using
   unique source and destination addresses as well as port numbers by
   sending a packet using that 4-tuple for a given transport protocol.

Perhaps:
   Successful interaction with a local firewall assumes the firewall

   using unique source and destination addresses as well as port
   numbers (i.e., a 4-tuple) by sending a packet using that 4-tuple
   for a given transport protocol.
-->


16) <!--[rfced] Please clarify what "one" refers to in "16-bit one's
complement Internet checksum". Is the checksum 16 bits?

Original:
   The calculation is the same as the 16-bit one's complement Internet
   checksum used in the IPv4 packet header (see section 3.1 of
   [RFC0791]).
-->


17) <!--[rfced] May we rephrase the text in the parentheses for clarity as
follows?

Original:
   The client SHALL simultaneously start a test initiation timer so that
   if the Control phase fails to complete Test Setup and Test Activation
   exchanges in the allocated time, the client software SHALL exit
   (close the UDP socket and indicate an error message to the user).

Perhaps:
   The client SHALL simultaneously start a test initiation timer so that
   if the Control phase fails to complete Test Setup and Test Activation
   exchanges in the allocated time, the client software SHALL exit
   (i.e., the UDP socket will close and an error message will be displayed 
   to the user).

18) <!--[rfced] Is "by most significant byte" correct, or should it be
"with the most significant byte" as shown below?

Original:
   The UDP PDU format layout SHALL be as follows (big-endian AB,
   starting by most significant byte ending by least
   significant byte):

   The UDP PDU format layout SHALL be as follows (big-endian AB,
   starting with the most significant byte and ending with
   the least significant byte):

19) <!--[rfced] FYI: For Figures 2, 4, 6, 8, and 10, we moved the bit
ruler over one space to the right so that the numbers are
positioned over the dashes rather than the plus signs to match
use in the RFC Series.
-->


20) <!--[rfced] Section 6.1. We are having trouble parsing these
sentences. May we update as shown below for clarity?

Original:
 lowThresh: Two two-octet field, low threshold Low on the Range of
    Round Trip Time variation, RTT (Range is values above minimum RTT, see
    also Table 3 [TR-471].

 upperThresh: Two two-octet field, upper threshold Low on the Range
    of Round Trip Time variation, RTT (Range is values above minimum
    RTT, see also Table 3 of [TR-471].

Perhaps:

    Range of Round-Trip Time (RTT) variation (the range is composed 
    of values above the minimum RTT); see also Table 3 [TR-471].

 upperThresh: Two two-octet fields, with an upper threshold Low on
    the Range of RTT variation (the range is composed of values above 
    the minimum RTT); see also Table 3 of [TR-471].

21) <!--[rfced] We note that the following sentences refer to "Loss,
Reordering, and Duplication" differently. Please let us know
if/how they can be updated for consistency (perhaps "loss,
out-of-order, and duplicate totals").

In addition, under Section 6.1, we updated "default true" to "default
is True".  Please let us know if this changes the intended meaning.

Original:
(Section 6.1)
   ignoreOooDup: ... When False, Loss, Reordering and
      Duplication are all counted as sequence number errors, default
      True (see also Table 3 of [TR-471]).

(Section 7.1)
   lpduSeqNo:  A four-octet field indicating the Load PDU sequence
      number (starting at 1).  Used to determine loss, out-of-order,
      and duplicates.

(Section 7.2)
   seqErrLoss/seqErrOoo/seqErrDup:  Three four-octet fields,
         populated by the Loss, out-of-order, and duplicate totals.

Perhaps:

22) <!--[rfced] May we clarify the text in parentheses as shown below
(i.e., update "having been set to CHTA_SRIDX_DEF" to "and if the
parameters were set to CHTA_SRIDX_DEF")? Note that there are two
instances in the text.

23) <!--[rfced] We are having trouble parsing "SHALL display/report a
relevant message to the ... management process". Is "process"
essential to the sentence? Please let us know how we may update
the text for clarity.

Original:
   If the client receives a Test Activation cmdResponse field value that
   indicates an error, the client SHALL display/report a relevant
   message to the user or management process and exit.

   indicates an error, the client SHALL display/report a relevant
   message to the user or management and exit.

24) <!--[rfced] May we rephrase "adds the possibility to" to "provides the
option to" for clarity?

Original:
   Algorithm C operation and modes are similar to B, but C uses
   multiplicative increases in the fast mode to reach the Gigabit
   range quickly and adds the possibility to re-try the fast mode
   during a test (which improves the measurement accuracy in dynamic
   or error-prone access, such as radio access).

Perhaps:
   Algorithm C operation and modes are similar to B, but C uses
   multiplicative increases in the fast mode to reach the gigabit
   range quickly and provides the option to retry the fast mode 
   during a test (which improves the measurement accuracy in 
   dynamic or error-prone access, such as radio access).

25) <!--[rfced] Please review the formatting of the list in Section 7.2,
in particular the indentation of terms following "SisSav". Please
let us know if this is correct (sisSav consists of all the fields
that follow) or if it needs an update.

26) <!--[rfced] Please clarify what 2 instances of "those" refer to in
this sentence.

Original:
   When considering privacy of those involved in measurement or those
   whose traffic is measured, the sensitive information available to
   potential observers is greatly reduced when using active techniques
   which are within this scope of work. 
-->


27) <!-- [rfced] We have included some specific questions about the IANA
text below. In addition to responding to those questions, please
review all of the IANA-related updates carefully and let us know
if any further changes are needed.

a) Section 11.1. In the "Service Name and Transport Protocol Port
Number Registry" <https://www.iana.org/assignments/
service-names-port-numbers/>, the Transport Protocol is listed as
"udp", but in this document, it is listed as "UDP". For consistency,
should this term be lowercase or uppercase? Note that we will
communicate any changes to the registry to IANA.

In this document:
   Transport Protocol:  UDP

In the registry:
   Transport Protocol:  upd

- Also in Section 11.1, should "performance measurement protocol" or 
"performance measurement" perhaps be capitalized? (We note that it
appears as "Performance Measurement protocol" in RFC 6812.)

Current:
   Description:  UDP-based IP-Layer Capacity and performance 
      measurement protocol

Perhaps:
   Description:  UDP-based IP-Layer Capacity and Performance 
      Measurement protocol

b) IANA has added the following entry to the "KeyTable KDFs" registry. 
Is "[RFC6234]" the correct reference? Should this document also be 
added as a reference?

Current:
   KDF           Description                    Reference
   - - - - - - - - - - - - - - - - - - - - - - - - - - - - 
   HMAC-SHA-256  HMAC using the SHA-256 hash    [RFC6234]

c) May we update the note in the "UDP Speed Test Protocol (UDPSTP)"
registry group for clarity as shown below (i.e., uppercase
"experimental use" and add "are expected")? If so, we will ask IANA to
update accordingly.

Original:
   Note: Values reserved for experimental use are not expected to be
   used on the Internet, but for experiments that are confined to closed
   environments.

Perhaps:
   Note: Values reserved for Experimental Use are not
   expected to be used on the Internet but are expected to be used for
   experiments that are confined to closed environments.


d) We note that the "Range" and "Value" column headers in the tables
listed below are different than what is listed in the corresponding
IANA registries. Should the IANA registries (which only list "Range"
and "Value") be updated to match this document, or should "(Hex)",
"(Decimal)", "(Bitmap)", "(Capital alphabet / UTF-8)", and
"(Numeric)" be removed from this document to match the IANA registries?

Current in this document (first header columns of the tables):
  Table 2: Range(Hex) 
  Tables 4, 8, 10, 12, and 18: Range(Decimal)
  Tables 6 and 14: Range(Bitmap)
  Table 16: Range(Capital alphabet / UTF-8)
  Table 17: Value(Numeric)


e) In the "PDU Identifier" registry, we note that IANA has listed
"0x0001-0x7F00 / Specification Required" twice. We will ask IANA to
remove the duplicate entry. We also note that "0x8000-0xFFFE / IETF
Review" is missing. We will ask IANA to add it.

May we update the order of Table 2 in this document and in the IANA
registry as shown under the "Suggested" text below so that there is
consistency with the order of the number ranges?

Current in the "PDU Identifier" registry:

   Range           Registration Procedures
   - - - - - - - - - - - - - - - - - - - -
   0x0000          Reserved
   0x0001-0x7F00   Specification Required
   0x7F01-0x7FE0   Reserved for Experimental Use
   0x7FE1-0x7FFF   Reserved for Private Use
   0x0001-0x7F00   Specification Required
   0xFFFF          Reserved

Suggested (for the registry and this document):

   Range           Registration Procedures
   - - - - - - - - - - - - - - - - - - - -
   0x0000          Reserved
   0x0001-0x7F00   Specification Required
   0x7F01-0x7FE0   Experimental Use
   0x7FE1-0x7FFF   Private Use
   0x8000-0xFFFE   IETF Review
   0xFFFF          Reserved


f) In Table 7 under the description for value 0x02, is the hyphen
necessary in "IP-header" or may we remove it per use in most RFCs?
Also, may we add "an" before "IP header"?

Original:
   0x02   Use Traditional MTU (1500 bytes with IP-header)

Perhaps:
   0x02   Use Traditional MTU (1500 bytes with an IP header)


g) In the "Test Activation PDU Rate Adjustment Algo." registry name,
is the period after "Algo." necessary? We ask as there is no period 
after the "rateAdjAlgo" field, for example.

Original:
   "Test Activation PDU Rate Adjustment Algo." registry

Perhaps:
   "Test Activation PDU Rate Adjustment Algo" registry


h) In Tables 11 and 19, how may we clarify the description for value 0. 
Is "Request" referring to the "Setup Request" or other?

Original:
   0    None (used by client in Request)

Perhaps:
   0    None (used by client in the Setup Request)

32) <!-- [rfced] Terminology

a) Throughout the text, the following terminology appears to be used 
inconsistently. Please review these occurrences and let us know if/how they
may be made consistent.  

 [byte] vs. byte
 [ms] vs. ms vs. millisecond
 [s] vs. second
 [us] vs. us vs. microsecond

 Loss vs. loss

 Parameter vs. parameter
 
 Range vs. range

 Sending Rate Table vs. sending rate table
   [Note: RFC 9097 uses the lowercase form. Also consider
   whether the following terms need an update:
     - Sending Rate structure
     - Configured Sending Rate Table index]


b) FYI - We updated the following terms to reflect the forms on the
right for consistency within this document and/or with other
RFCs. Please let us know if any further updates are needed.

 Bit rate -> bit rate
 data phase -> Data phase
 command response -> Command Response
 Firewall -> firewall (per RFC 9097)
 IP-layer Capacity metric -> IP-layer Capacity Metric (per RFC 9097)
 Load Rate Adjustment Algorithm -> load rate adjustment algorithm
 Maximum IP-Layer Capacity metric -> Maximum IP-Layer Capacity Metric 
                                      (per RFC 9097)

 Payload Content -> payload content (per 9097)
 Security mode of operation -> security mode of operation
 Setup request -> Setup Request
 test activation request -> Test Activation Request
 Test traffic -> test traffic (per RFC 9097)
 Traditional size -> traditional size


c) We note the following variances in the text - are these terms the
same or different? Please let us know if any updates are needed for
consistency.

  Bulk Transport Capacity vs. Bulk Capacity

  Command Server Response code vs. Command Response code 

  Maximum IP-Layer Capacity Metric vs. Maximum IP Capacity

  Setup Request PDU (4 instances) vs. Request PDU (4 instances)
    [Note: Is "Request PDU" correct or should it be updated to 
    "Setup Request PDU" or "Test Activation Request PDU"?]


d) "Sub-Interval" and "sisSav"

i) We note the following variances related to "sisSav" (placement and
inclusion of "saved"). Should these be made consistent?

Original:
   sisSav: Sub-interval statistics saved (completed)

   struct subIntStats sisSav;  // Sub-interval saved stats

   Sub-Interval Statistics structure (sisSav)

Perhaps:
   sisSav: Sub-interval statistics saved (completed)

   struct subIntStats sisSav;  // Sub-interval stats saved

   Sub-interval statistics saved (sisSav) structure

ii) We also note the following variances; please let us know
how we may make these consistent.

   Sub-Interval vs. Sub-interval vs. sub-interval
      
    Some examples:
      Sub-interval sequence

e) We note the use of "Null Request". Should this perhaps be 
"NULL Request", "NULL request", or other? We ask as we only 
see "NULL request" used in other RFCs.


f) We note that the following terms appear as uppercase in the running
text but as lowercase in the descriptions in Figures 3, 5, 7, 9, and/or
11. Should we update the figures to reflect the uppercase forms for
consistency or is the case okay as is?

c) FYI - We updated "UDPST" to "UDPSTP" (one instance) as follows. Please 
let us know if that is not correct.

Original:
   The number n may depend on the implementation and on typical
   characteristics of environments, where UDPST is deployed (like
   mobile networks or Wi-Fi).

Current:
   The number n may depend on the implementation and on typical
   characteristics of environments, where UDPSTP is deployed (like
   mobile networks or Wi-Fi).

Style Guide <https://www.rfc-editor.org/styleguide/part2/#inclusive_language>
and let us know if any changes are needed.  Updates of this nature typically
result in more precise language, which is helpful for readers.

Please consider whether "traditional" should be updated for clarity.  
While the NIST website 
<https://web.archive.org/web/20250214092458/https://www.nist.gov/
nist-research-library/nist-technical-series-publications-author-instructions#table1>
indicates that this term is potentially biased, it is also ambiguous.  
"Tradition" is a subjective term, as it is not the same for everyone.

Instructions for Completing AUTH48

Your document has now entered AUTH48.  Once it has been reviewed and 
approved by you and all coauthors, it will be published as an RFC.  
If an author is no longer available, there are several remedies 
available as listed in the FAQ (https://www.rfc-editor.org/faq/).

You and you coauthors are responsible for engaging other parties 
(e.g., Contributors or Working Group) as necessary before providing 
your approval.

Planning your review 
---------------------

Please review the following aspects of your document:

*  RFC Editor questions

  Please review and resolve any questions raised by the RFC Editor 
  that have been included in the XML file as comments marked as 
  follows:

  <!-- [rfced] ... -->

  These questions will also be sent in a subsequent email.

*  Changes submitted by coauthors 

  Please ensure that you review any changes submitted by your 
  coauthors.  We assume that if you do not speak up that you 
  agree to changes submitted by your coauthors.

*  Content 

  Please review the full content of the document, as this cannot 
  change once the RFC is published.  Please pay particular attention to:
  - IANA considerations updates (if applicable)
  - contact information
  - references

*  Copyright notices and legends

  Please review the copyright notice and legends as defined in
  RFC 5378 and the Trust Legal Provisions 
  (TLP – https://trustee.ietf.org/license-info).

*  Semantic markup

  Please review the markup in the XML file to ensure that elements of  
  content are correctly tagged.  For example, ensure that <sourcecode> 
  and <artwork> are set correctly.  See details at 
  <https://authors.ietf.org/rfcxml-vocabulary>.

*  Formatted output

  Please review the PDF, HTML, and TXT files to ensure that the 
  formatted output, as generated from the markup in the XML file, is 
  reasonable.  Please note that the TXT will have formatting 
  limitations compared to the PDF and HTML.


Submitting changes
------------------

To submit changes, please reply to this email using ‘REPLY ALL’ as all 
the parties CCed on this message need to see your changes. The parties 
include:

  *  your coauthors

  *  [email protected] (the RPC team)

  *  other document participants, depending on the stream (e.g., 
     IETF Stream participants are your working group chairs, the 
     responsible ADs, and the document shepherd).

  *  [email protected], which is a new archival mailing list 
     to preserve AUTH48 conversations; it is not an active discussion 
     list:

    *  More info:
       
https://mailarchive.ietf.org/arch/msg/ietf-announce/yb6lpIGh-4Q9l2USxIAe6P8O4Zc

    *  The archive itself:
       https://mailarchive.ietf.org/arch/browse/auth48archive/

    *  Note: If only absolutely necessary, you may temporarily opt out 
       of the archiving of messages (e.g., to discuss a sensitive matter).
       If needed, please add a note at the top of the message that you 
       have dropped the address. When the discussion is concluded, 
       [email protected] will be re-added to the CC list and 
       its addition will be noted at the top of the message. 

You may submit your changes in one of two ways:

An update to the provided XML file
— OR —
An explicit list of changes in this format

Section # (or indicate Global)

OLD:
old text

NEW:
new text

You do not need to reply with both an updated XML file and an explicit 
list of changes, as either form is sufficient.

We will ask a stream manager to review and approve any changes that seem
beyond editorial in nature, e.g., addition of new text, deletion of text, 
and technical changes.  Information about stream managers can be found in 
the FAQ.  Editorial changes do not require approval from a stream manager.


Approving for publication
--------------------------

To approve your RFC for publication, please reply to this email stating
that you approve this RFC for publication.  Please use ‘REPLY ALL’,
as all the parties CCed on this message need to see your approval.
