...FB: Good catch. We'll remove the word "either". This is an editorial lef=
t-over from the time when the draft had two methods mentioned (SSSS and nes=

...FB: A network element that compares the iteratively (by all nodes that p=
articipate in POT on the path) computed result which is carried along in th=
e packet with the secret and concludes whether the computed result matches =
the secret. If the two match, the packet transit is proven. The role of the=
 verifier naturally assumes that the packets had a chance to traverse the n=
odes subject to POT before arriving at the verifier.

We can add a short paragraph with such an explanation to the document to en=
sure the role of the verifier is properly explained.

...FB: The scope of this draft is the definition of methods for proof-of-tr=
ansit. Like I mentioned in an earlier discussion on the SFC mailing list:
An implementor of POT for SFC with NSH would need to rely on several docume=
nts:
    - draft-ietf-sfc-proof-of-transit: for the POT concept and mechanism
    - draft-ietf-ippm-ioam-data: for the definition of POT related data fie=
lds in IOAM
    - draft-ietf-sfc-ioam-nsh: for the definition of the encapsulation of P=
OT related data fields in IOAM into NSH
What you seem to be missing is an architecture-level discussion of how the =
mix of POT+IOAM+NSH apply to the SFC architecture. IMHO this would best be =
addressed by an architecture-level document, because all of the above menti=
oned documents are focused on a specific subject and neither of the documen=
ts would be a good fit for an architecture level definition. IMHO the best =
place for that would be a "RFC 7665bis" document - i.e. we'd extend the SFC=
 architecture with a discussion how POT applies.

That said - and this is along the lines of your comment wrt/ the verifier: =
What is feasible within the scope of the document is to have an explanation=
 of the different roles in POT in the document (e.g. we can do this in sect=
ion 3), where we discuss the role of nodes which participate in POT, the ve=
rifier and the controller role, i.e.

* Node: A network element through which packet transit has to be proven.
* Controller: The Controller that creates secrets and secrets shares and co=
nfigures the nodes for POT operations.
* Verifier: A network element that compares the iteratively (by all nodes t=
hat participate in POT on the path) computed result which is carried along =
in the packet with the secret and concludes whether the computed result mat=
ches the secret. If the two match, the packet transit is proven. The role o=
f the verifier naturally assumes that the packets had a chance to traverse =
the nodes subject to POT before arriving at the verifier.

....FB: Good catch. We'll remove the word "either". This is an editorial le=
ft-over from the time when the draft had two methods mentioned (SSSS and ne=

....FB: A network element that compares the iteratively (by all nodes that =
participate in POT on the path) computed result which is carried along in t=
he packet with the secret and concludes whether the computed result matches=
 the secret. If the two match, the packet transit is proven. The role of th=
e verifier naturally assumes that the packets had a chance to traverse the =
nodes subject to POT before arriving at the verifier.

We can add a short paragraph with such an explanation to the document to en=
sure the role of the verifier is properly explained.

....FB: The scope of this draft is the definition of methods for proof-of-t=
ransit. Like I mentioned in an earlier discussion on the SFC mailing list:
An implementor of POT for SFC with NSH would need to rely on several docume=
nts:
    - draft-ietf-sfc-proof-of-transit: for the POT concept and mechanism
    - draft-ietf-ippm-ioam-data: for the definition of POT related data fie=
lds in IOAM
    - draft-ietf-sfc-ioam-nsh: for the definition of the encapsulation of P=
OT related data fields in IOAM into NSH
What you seem to be missing is an architecture-level discussion of how the =
mix of POT+IOAM+NSH apply to the SFC architecture. IMHO this would best be =
addressed by an architecture-level document, because all of the above menti=
oned documents are focused on a specific subject and neither of the documen=
ts would be a good fit for an architecture level definition. IMHO the best =
place for that would be a "RFC 7665bis" document - i.e. we'd extend the SFC=
 architecture with a discussion how POT applies.

That said - and this is along the lines of your comment wrt/ the verifier: =
What is feasible within the scope of the document is to have an explanation=
 of the different roles in POT in the document (e.g. we can do this in sect=
ion 3), where we discuss the role of nodes which participate in POT, the ve=
rifier and the controller role, i.e.

* Node: A network element through which packet transit has to be proven.
* Controller: The Controller that creates secrets and secrets shares and co=
nfigures the nodes for POT operations.
* Verifier: A network element that compares the iteratively (by all nodes t=
hat participate in POT on the path) computed result which is carried along =
in the packet with the secret and concludes whether the computed result mat=
ches the secret. If the two match, the packet transit is proven. The role o=
f the verifier naturally assumes that the packets had a chance to traverse =
the nodes subject to POT before arriving at the verifier.

&gt; Subject: Re: [sfc] IETF WG state changed for draft-ietf-sfc-proof-of-t=
ransit<br>
&gt; <br>
&gt; Hello all,<br>
&gt; <br>
&gt; I support progressing this draft to an Experimental RFC. Please consid=
er the<br>
&gt; following comments (mostly editorial):<br>
&gt; <br>
&gt; 1)<br>
&gt; Not sure what is implied by the sentence below (Sec 1):<br>
&gt; &gt; A particular set of nodes &quot;to be verified&quot; is either de=
scribed by a set of shares<br>
&gt; of a single secret.<br>
....FB: Good catch. We'll remove the word &quot;either&quot;. This is an ed=
itorial left-over from the time when the draft had two methods mentioned (S=
SSS and nested crypto).<br>
<br>
&gt; <br>
&gt; 2)<br>
&gt; The following sentence (Sec 1) describes about controller nodes and ve=
rifier<br>
&gt; nodes. While the former's role could be easily understood, I am not su=
re the<br>
&gt; latter node role is clearly defined. If it does not limit the scope, w=
e may use only<br>
&gt; one terminology or clarify the difference, if we need to refer about t=
wo roles.<br>
&gt; &gt; The complete secret set is only known to&nbsp; the controller and=
 a verifier node,<br>
&gt; which is typically the ultimate node on a path that performs verificat=
ion..<br>
<br>
....FB: A network element that compares the iteratively (by all nodes that =
participate in POT on the path) computed result which is carried along in t=
he packet with the secret and concludes whether the computed result matches=
 the secret. If the two match, the
 packet transit is proven. The role of the verifier naturally assumes that =
the packets had a chance to traverse the nodes subject to POT before arrivi=
ng at the verifier.<br>
<br>
We can add a short paragraph with such an explanation to the document to en=
sure the role of the verifier is properly explained.<br>
<br>
&gt; <br>
&gt; 3)<br>
&gt; Sec 7.9.1<br>
&gt; OLD<br>
&gt;&nbsp; Since these schemes introduce at least additional control requir=
ements, the<br>
&gt; selection of order verification SHOULD be configurable the Controller<=
br>
&gt; management interface NEW Since these schemes introduce at least additi=
onal<br>
&gt; control requirements, the selection of order verification SHOULD be<br=
>
&gt; configurable BY the Controller management interface<br>
<br>
....FB: Thanks. We'll update the sentence accordingly.<br>
<br>
&gt; <br>
&gt; 4)<br>
&gt; Sec 3.2 has the words Solution Approach duplicated<br>
<br>
....FB: Thanks. Good catch. <br>
&gt; <br>
&gt; 5)<br>
&gt; Not sure if there is a missing reference here (Sec: 3.3.1.3):<br>
&gt; &gt; For a general way to compute the modular multiplicative inverse, =
see&nbsp;&nbsp; e.g.,<br>
&gt; the Euclidean algorithm.<br>
<br>
....FB: We'll add a reference to <a href=3D"http://en.wikipedia.org/wiki/Mo=
dular_multiplicative_inverse#Computation">
http://en.wikipedia.org/wiki/Modular_multiplicative_inverse#Computation</a>=
<br>
<br>
&gt; <br>
&gt; 6)<br>
&gt; General comment: It may be helpful to either have a diagram or a point=
er to a<br>
&gt; diagram pointing out the different roles like Controller, ingress node=
. Also I am<br>
&gt; not sure if there is text (other than the section in Security Consider=
ations) that<br>
&gt; explains that POT should be deployed in a set of nodes under a single<=
br>
&gt; administrative domain.<br>
<br>
....FB: The scope of this draft is the definition of methods for proof-of-t=
ransit. Like I mentioned in an earlier discussion on the SFC mailing list:<=
br>
An implementor of POT for SFC with NSH would need to rely on several docume=
nts:<br>
&nbsp;&nbsp;&nbsp; - draft-ietf-sfc-proof-of-transit: for the POT concept a=
nd mechanism<br>
&nbsp;&nbsp;&nbsp; - draft-ietf-ippm-ioam-data: for the definition of POT r=
elated data fields in IOAM<br>
&nbsp;&nbsp;&nbsp; - draft-ietf-sfc-ioam-nsh: for the definition of the enc=
apsulation of POT related data fields in IOAM into NSH<br>
What you seem to be missing is an architecture-level discussion of how the =
mix of POT&#43;IOAM&#43;NSH apply to the SFC architecture. IMHO this would =
best be addressed by an architecture-level document, because all of the abo=
ve mentioned documents are focused on a
 specific subject and neither of the documents would be a good fit for an a=
rchitecture level definition. IMHO the best place for that would be a &quot=
;RFC 7665bis&quot; document - i.e. we'd extend the SFC architecture with a =
discussion how POT applies.<br>
<br>
That said - and this is along the lines of your comment wrt/ the verifier: =
What is feasible within the scope of the document is to have an explanation=
 of the different roles in POT in the document (e.g. we can do this in sect=
ion 3), where we discuss the role
 of nodes which participate in POT, the verifier and the controller role, i=
.e.<br>
<br>
* Node: A network element through which packet transit has to be proven.<br=
>
* Controller: The Controller that creates secrets and secrets shares and co=
nfigures the nodes for POT operations.<br>
* Verifier: A network element that compares the iteratively (by all nodes t=
hat participate in POT on the path) computed result which is carried along =
in the packet with the secret and concludes whether the computed result mat=
ches the secret. If the two match,
 the packet transit is proven. The role of the verifier naturally assumes t=
hat the packets had a chance to traverse the nodes subject to POT before ar=
riving at the verifier.<br>
<br>
Thanks again, Frank<br>
<br>

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Service Function Chaining WG of the IETF.

        Title           : Explicit Congestion Notification (ECN) and Congestion Feedback Using the Network Service Header (NSH)
        Authors         : Donald E. Eastlake
                          Bob Briscoe
                          Andrew G. Malis
	Filename        : draft-ietf-sfc-nsh-ecn-support-03.txt
	Pages           : 21
	Date            : 2020-07-03

Abstract:
   Explicit congestion notification (ECN) allows a forwarding element to
   notify downstream devices of the onset of congestion without having
   to drop packets. Coupled with a means to feed back information about
   congestion to upstream nodes, this can improve network efficiency
   through better congestion control, frequently without packet drops.
   This document specifies ECN and congestion feedback support within a
   Service Function Chaining (SFC) domain through use of the Network
   Service Header (NSH, RFC 8300) and IP Flow Information Export (IPFIX,
   draft-ietf-tsvwg-tunnel-congestion-feedback).

Subject: Encourage people to visit NomCom during office hours
Date: Sat, 25 Jul 2020 20:16:18 +0000
From: STARK, BARBARA H <bs7652@att.com>
To: 'Working Group Chairs' <wgchairs@ietf.org>

Hi WG Chairs,
Could you let your groups know that if anyone is interested in finding 
out more about NomCom or about standing for an I* position (or just 
wants to say Hi), they can visit with NomCom during office hours next 
week? Thx,
Barbara

Here is the message I sent to the ietf list:
-------------------------------------------------------------------------------------------------------------------------------
I wanted to let everyone know that NomCom will be holding some office 
hours next week. If you want to stop by and talk with us (just to say 
Hi, ask about NomCom, ask about being a nominee for the various I* 
positions, etc.), we'd love to see and hear from you.

The date and times (which are also posted on the IETF 108 Agenda) are:

     Monday, July 27, 16:00-17:00 UTC WebEx: 
https://ietf.webex.com/ietf/j.php?MTID=m13c41ae118e538b6d25efb25d41307ee
     Tuesday, July 28, 09:30-10:30 UTC WebEx: 
https://ietf.webex.com/ietf/j.php?MTID=m6132b48c3eac5469a41043ce55dada20
     Thursday, July 30, 20:00-21:00 UTC WebEx: 
https://ietf.webex.com/ietf/j..php?MTID=mf7ce451931e35818fd7b3bf44abd1026

In addition to being available by WebEx, those of us who can will 
simultaneously be on Gather.Town (possibly in a special NomCom corner). 
To find us, the easiest way is to go to the Participants list (at right 
of the Gather screen), find "Barbara Stark", left click on my name and 
select "Locate".

See you next week!
Barbara
