This is a very interesting proposal.  I'd suggest a couple of small
changes:

   Abstract

   ... with a Maximum Time Interval Error less than 25
   microseconds by a minute.

I think that "by a minute" means "after operating for one minute".  You
want the Abstract to be as clear as possible.

   While synchronized absolute clocks aim on a
   measurement of exact time differences between them, ...

My impression is that NTP aims on a measurement of time differences
between the clock and UTC; measurement of exact time differences between
the clocks in an NTP peering is only a means to that end.

These nodes include session state, sent and receive packet count, last sequence number received or transmitted, start time, repeat count, tcp/ip address and port numbers etc. Nothing jumped out as particularly privacy sensitive.

In some scenarios knowing the current sequence number is useful to an
attacker, e.g., in TCP for sending off-path RST.  I don't remember enough
of how TWAMP works to say offhand whether an analogous disruption is
possible in some (unauthenticated?) cases.

> One field that did catch my attention was the ‘token’ field, which is defined as "This parameter holds the 64 octets containing the concatenation of a 16-octet Challenge, a 16-octet AES Session-key used for encryption, and a 32-octet HMAC-SHA1 Session-key used for authentication; see also the last paragraph of Section 6 in RFC 4656.”

I note that secdir is not on the recipients list, so if you want to get
specific feedback, someone will need to explicitly seek it out.

I also note that the cryptographic constructions used for TWAMP are quite
diverged from current best practices and appear to be fragile at best.  So
someone doing such an analysis might have to go through a fair amount of
effort to reach a conclusion (part of why I did not attempt such analysis
myself).  It might be safest to assume that being able to read the token
field gives an attacker the ability to disrupt a test session.

That is correct. But we do not store the sequence number, so they would have=
 to snoop the traffic to get the sequence number which they can, whether the=
y have the IP address/port number from the twamp module or not.=20

Ok. I will write something up for the 'token' attribute.=20

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IP Performance Measurement WG of the IETF.

        Title           : Advanced Unidirectional Route Assessment (AURA)
        Authors         : José Ignacio Alvarez-Hamelin
                          Al Morton
                          Joachim Fabini
                          Carlos Pignataro
	Filename        : draft-ietf-ippm-route-02.txt
	Pages           : 26
	Date            : 2018-07-02

Abstract:
   This memo introduces an advanced unidirectional route assessment
   (AURA) metric and associated measurement methodology, based on the IP
   Performance Metrics (IPPM) Framework RFC 2330.  This memo updates RFC
   2330 in the areas of path-related terminology and path description,
   primarily to include the possibility of parallel subpaths between a
   given Source and Destination pair, owing to the presence of multi-
   path technologies.

Thanks for addressing the various comments I made -- your resolutions 
all seem good to me. One comment on the security section, below:

Thanks. This is an improvement, but I'm still a bit concerned about the 
fact that the section speaks only in examples ("examples include" and 
"nodes such as") rather than explicitly identifying sensitive nodes, 
which is what I believe RFC 6087 anticipates. I also don't think that 
simply stating that the attacks that result from changing certain 
parameters "are obvious" is enough to satisfy either the spirit or 
letter of what is intended by:

Thanks for the work and thought that everyone involved in this document spent. I
find the model well described and easy to understand.

I agree with Ben's comments about including more information about the privacy
and security properties of specific entities in the module. See
<a class="moz-txt-link-freetext" href="https://trac.ietf.org/trac/ops/wiki/yang-security-guidelines">https://trac.ietf.org/trac/ops/wiki/yang-security-guidelines</a> for specific
guidance.

Since this conflicts with normative language in RFC 6087 §3.4 (and 6087bis
§3.7), it is a blocking defect that needs to be remedied prior to publication.

    Thanks. This is an improvement, but I'm still a bit concerned about
    the fact that the section speaks only in examples ("examples
    include" and "nodes such as") rather than explicitly identifying
    sensitive nodes, which is what I believe RFC 6087 anticipates. I
    also don't think that simply stating that the attacks that result

How about this?

OLD:

   Nodes such as 'admin-state' that cause test sessions to be created,
   or 'number-of-packets' that dictate how many packets are sent in any
   particular test session are obvious.  Examples of nodes that are
   particularly vulnerable include several timeout values put in the
   protocol to protect against sessions that are not active but are
   consuming resources.  Examples include the REFWAIT timeout parameter
   which determine whether to discontinue the session if no packets are
   received.  Nodes like 'count' and 'max-count-exponent' can cause a
   long time to be spent on PBKDF2 iterations.  In addition, nodes such
   as 'dscp' marked with different DSCP markings, can cause the test
   traffic on the network to be skewed, and the result manipulated.
   Finally, nodes within 'mode-preference-chain' which specify the
   'mode' and 'priority' values and indicate the preferred order of use
   by an operator, can for example, be manipulated to send
   unauthenticated or non-encrypted traffic, enabling a MITM attack.
   Limiting access to these nodes will limit the ability to launch an
   attack in network environments.


NEW:

   If written, the 'admin-state' node can cause unintended test sessions =
to be=20
   created. If the node 'number-of-packets' that dictates how=20
   many packets are sent in any particular test session is written=20
   with a large value, it can cause a test session to run longer=20
   than expected.  Nodes that are
   particularly vulnerable include several timeout values put in the
   protocol to protect against sessions that are not active but are
   consuming resources.  These are the REFWAIT timeout parameter
   which determine whether to discontinue the session if no packets are
   received, and nodes 'count' and 'max-count-exponent=E2=80=99 which =
can cause a
   long time to be spent on PBKDF2 iterations.  In addition,
   'dscp=E2=80=99 node marked with different DSCP markings, can cause =
the test
   traffic on the network to be skewed, and the result manipulated.
   Finally, nodes within 'mode-preference-chain' which specify the
   'mode' and 'priority' values and indicate the preferred order of use

   unauthenticated or non-encrypted traffic, enabling a MITM attack.
   Limiting access to these nodes will limit the ability to launch an

On the question of nodes that are privacy sensitive when they are =
readable, here is the text I was planning on adding.

"The =E2=80=98token=E2=80=99 node defined in the model, containing a =
concatenation of a Challenge, AES Session-key used for encryption, and =
HMAC-SHA1 Session-key used for authentication, is sensitive from a =
privacy perspective, and can be used to disrupt a test session. The =

Thanks for a quick response! These both look good to me. I'll clear my 
discuss when the next version of the document comes out.

Abstract:
   This document specifies a data model for client and server
   implementations of the Two-Way Active Measurement Protocol (TWAMP).
   The document defines the TWAMP data model through Unified Modeling
   Language (UML) class diagrams and formally specifies it using a NDMA-
   compliant YANG model.

Dear Authors,

I think I'm within nanoseconds of sending an Approved note for this draft,
but then noticed a couple of things I wanted to ask about first.

I noted that Tom Petch had flagged

Looking at -13, it has
         bit unauth-test-encrpyt-control {
which AM thought should be
         bit unauth-test-encrypt-control {


which he had previously flagged in -12.

He also mentioned

And s.5.2 has
Advances Stream and Sampling Framework [RFC7312],
which I think should be
Advanced Stream and Sampling Framework [RFC7312],


Which seems to be new.

Are these proposed changes correct?

Is this citation

   [UML]      ISO/IEC, "Information technology - Open Distributed
                Processing - Unified Modeling Language", April 2005.

sufficient for the expected reader? I noted that Adam's question mentioned
"ISO/IEC 19501:2005", which seems like a helpful detail if someone were
chasing the reference.

Just let me know. I'm happy to do these as RFC Editor notes, if they're
correct.

Spencer

Hmm. I seem to be missing his e-mail that catches that, but I can see it =
in the draft. So yes, it should be:

Hi Spencer,

Since I was investigating ion parallel, let me add:

Hi Spencer,

Dear Authors,

I think I'm within nanoseconds of sending an Approved note for this draft, =
but then noticed a couple of things I wanted to ask about first.

I noted that Tom Petch had flagged

Looking at -13, it has
         bit unauth-test-encrpyt-control {
which AM thought should be
         bit unauth-test-encrypt-control {

which he had previously flagged in -12.

Thanks for catching this. Yes it should be
bit unauth-test-encrypt-control {



He also mentioned

And s.5.2 has
Advances Stream and Sampling Framework [RFC7312],
which I think should be
Advanced Stream and Sampling Framework [RFC7312],

Which seems to be new.

Hmm. I seem to be missing his e-mail that catches that, but I can see it in=
 the draft. So yes, it should be:

Advanced Stream and Sampling Framework[RFC7312],



Are these proposed changes correct?

Yes.
[acm]

Let's add these as OLD/NEW to the REF Editor, Tom said that was fine...



Is this citation

             [UML]      ISO/IEC, "Information technology - Open Distributed
                        Processing - Unified Modeling Language", April 2005=
.

sufficient for the expected reader? I noted that Adam's question mentioned =
"ISO/IEC 19501:2005", which seems like a helpful detail if someone were cha=
sing the reference.

Yes, I agree it would be helpful to have that reference.
[acm]
It seems that the Title is not enough for a popular search engine
to find the right standard.  I also learned that there is a
related spec by searching with the title:

https://www.iso.org/standard/68641.html ISO/IEC 19793:2015

Only searching with the exact number did I get the right spec.
Note that the exact title is a little longer:

ISO/IEC 19501:2005 (OMG-UML VER 1.3)
Information technology -- Open Distributed Processing
-- Unified Modeling Language (UML) Version 1.4.2

We can handle this with an OLD/NEW as well, IMO.

Al




Just let me know. I'm happy to do these as RFC Editor notes, if they're cor=
rect.

Thank you.



Spencer

Abstract:
   This document specifies a data model for client and server
   implementations of the Two-Way Active Measurement Protocol (TWAMP).
   The document defines the TWAMP data model through Unified Modeling
   Language (UML) class diagrams and formally specifies it using a NDMA-
   compliant YANG model.

Abstract:<br>
&nbsp; &nbsp;This document specifies a data model for client and server<br>
&nbsp; &nbsp;implementations of the Two-Way Active Measurement Protocol (TW=
AMP).<br>
&nbsp; &nbsp;The document defines the TWAMP data model through Unified Mode=
ling<br>
&nbsp; &nbsp;Language (UML) class diagrams and formally specifies it using =
a NDMA-<br>
&nbsp; &nbsp;compliant YANG model.<br>

I'm re-sending, because the message came back from the
IETF alias system truncated, and info on the reference
was not included...

Hi Spencer,

Since I was investigating in parallel, let me add:

Dear Authors,

I think I'm within nanoseconds of sending an Approved note for this draft, =
but then noticed a couple of things I wanted to ask about first.

I noted that Tom Petch had flagged

Looking at -13, it has
         bit unauth-test-encrpyt-control {
which AM thought should be
         bit unauth-test-encrypt-control {

which he had previously flagged in -12.

Thanks for catching this. Yes it should be
bit unauth-test-encrypt-control {


He also mentioned

And s.5.2 has
Advances Stream and Sampling Framework [RFC7312],
which I think should be
Advanced Stream and Sampling Framework [RFC7312],

Which seems to be new.

Hmm. I seem to be missing his e-mail that catches that, but I can see it in=
 the draft. So yes, it should be:

Advanced Stream and Sampling Framework[RFC7312],


Are these proposed changes correct?

Yes.
[acm]

Let's add these as OLD/NEW to the REF Editor, Tom said that was fine...


Is this citation

             [UML]      ISO/IEC, "Information technology - Open Distributed
                        Processing - Unified Modeling Language", April 2005=
.

sufficient for the expected reader? I noted that Adam's question mentioned =
"ISO/IEC 19501:2005", which seems like a helpful detail if someone were cha=
sing the reference.

Yes, I agree it would be helpful to have that reference.
[acm]
It seems that the Title is not enough for a popular search engine
to find the right standard.  I also learned that there is a
related spec by searching with the title:

https://www.iso.org/standard/68641.html ISO/IEC 19793:2015

Only searching with the exact number did I get the right spec.
Note that the exact title is a little longer:

ISO/IEC 19501:2005 (OMG-UML VER 1.3)
Information technology -- Open Distributed Processing
-- Unified Modeling Language (UML) Version 1.4.2

We can handle this with an OLD/NEW as well, IMO.

Al



Just let me know. I'm happy to do these as RFC Editor notes, if they're cor=
rect.

Thank you.


Spencer

Abstract:
   This document specifies a data model for client and server
   implementations of the Two-Way Active Measurement Protocol (TWAMP).
   The document defines the TWAMP data model through Unified Modeling
   Language (UML) class diagrams and formally specifies it using a NDMA-
   compliant YANG model.

Abstract:<br>
&nbsp; &nbsp;This document specifies a data model for client and server<br>
&nbsp; &nbsp;implementations of the Two-Way Active Measurement Protocol (TW=
AMP).<br>
&nbsp; &nbsp;The document defines the TWAMP data model through Unified Mode=
ling<br>
&nbsp; &nbsp;Language (UML) class diagrams and formally specifies it using =
a NDMA-<br>
&nbsp; &nbsp;compliant YANG model.<br>

Since you're sending this directly to me, I got untruncated copies, and was
able to add the RFC Editor Notes you and Manesh approved, and sent the
Approved note to the IESG Secretary.

I THINK you can see them at
https://datatracker.ietf.org/doc/draft-ietf-ippm-twamp-yang/writeup/ (but
I'm logged in as an AD), so please let me know if you can't see them, and
we'll work around that.

Thanks for all your hard work. You should see the announcement for this
draft tomorrow (unless the entire secretariat is flying to Montreal).

It is also the latest addition to the AD slides on completed work since
IETF 101 for TSVAREA ...

Spencer

The IESG has approved the following document:
- 'Two-Way Active Measurement Protocol (TWAMP) Data Model'
  (draft-ietf-ippm-twamp-yang-13.txt) as Proposed Standard

This document is the product of the IP Performance Measurement Working Group.

The IESG contact persons are Mirja Kühlewind and Spencer Dawkins.

A URL of this Internet Draft is:
https://datatracker.ietf.org/doc/draft-ietf-ippm-twamp-yang/





Technical Summary

  This document specifies a data model for client and server 
   implementations of the Two-Way Active Measurement Protocol (TWAMP).
  The TWAMP data model is described through Unified Modeling Language 
   (UML) class diagrams and formally specified using YANG.

  The Two-Way Active Measurement Protocol (TWAMP) [RFC5357] is used 
   to measure network performance parameters such as latency, bandwidth,
   and packet loss by sending probe packets and measuring their experience 
   in the network.  To date, TWAMP implementations do not come
   with a standard management framework and, as such, configuration depends 
   on proprietary mechanisms developed by the corresponding
   TWAMP vendor.  This document addresses this gap by formally specifying the 
   TWAMP data model using YANG.

Working Group Summary

  This document was presented and discussed in IETF96, IETF97, IETF98 and IETF99.  
   There has also been discussion on the email list.   

  There were questions raised as to the inclusion of TWAMP Light in this document.  
   The consensus was that TWAMP Light is not adequately specified as a protocol to 
   base a YANG model on.

Document Quality

   The document was reviewed and comments were provided in both the IETF meetings 
   and on the IPPM WG mailing list. 

   A YANG doctors review was requested for the YANG module in the document and 
   was provided by Jan Lindblad. A number of Jan's suggestions were implemented. 

   AT&T has an implementation.  Viavi was working on an implementation for testing 
   Ethernet. 

Personnel

  The Document Shepherd is Nalini Elkins.  
   The Responsible Area Director is Spencer Dawkins.

Hi Rakesh,
thank you for bringing this draft up for discussion. There was not enough
time to ask questions at the SPRING WG meeting and this is a very good
opportunity.
I understand that you've proposed to use RFC 6374 to encode PM operations
and measurements. Also, you've referenced work on OWAMP and TWAMP. But I
don't find any reference to STAMP
<https://tools.ietf.org/html/draft-ietf-ippm-stamp-01>in the draft. How
would you position STAMP, its optional extensions
<https://tools.ietf.org/html/draft-mirsky-ippm-stamp-option-tlv-01>, and YANG
model <https://tools.ietf.org/html/draft-ietf-ippm-stamp-yang-01> in
comparison with your new draft?

Regards,
Greg

Greetings, all,

WGLC has completed on draft-ietf-ippm-port-twamp-test; are there any =
volunteers to shepherd the document?

(For those who have not done so before, the primary role of the document =
shepherd is to review discussion on the draft and fill out a document =
shepherd write-up to summarize the WG's process for submission to the =
IESG.  This document is a relatively simple one and had a =
not-very-complicated process, so this would be a good first document for =
a new shepherd, if someone would like to try it out. :)

Thanks, cheers,

Brian (as IPPM WG co-chair)

Greetings, all,

First, thanks to Tianran Zhou for volunteering to shepherd =
draft-ietf-ippm-port-twamp-test!

As noted a few meeting cycles ago, we should be assigning shepherds when =
we adopt working group documents. We've done a less than perfect job of =
this recently. So, we're looking for volunteers to shepherd the =
following documents:

- draft-ietf-ippm-ioam-data
- draft-ietf-ippm-route
- draft-ietf-ippm-stamp and draft-ietf-ippm-stamp-yang (should be =
shepherded together)

Please consider volunteering by sending a message to =
ippm-chairs@ietf.org.

Thanks, cheers,

Brian (as WG co-chair)
