(Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-dots-server-discovery/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Figure 2. Editorial. Expand DMS somewhere in the surrounding text. Section 3. Editorial. Per “Dynamic means to discover DOTS servers in a deterministic manner are interesting from an operational standpoint”, this reads like a problem statement. Should it be restated as “dynamic discovery needs to be deterministic”? Section 4. Editorial. Recommend not using the colloquialism “whack-a-mole”. Section 4. Per “DOTS clients will prefer information received from the discovery methods in the order listed”, does that mean the order list of 1, 2, 3 in the text above? If so, perhaps make that clearer. Section 4. Editorial. s/The discovery method is reiterated/The discovery method is repeated/ Section 5. I don’t have a better IETF reference, but RFC6125 is 9 years old so if something newer could be found that would be great. Section 8.3. In the absence of DNSSEC, DoT or DoH could also provide a degree of path integrity protection.

The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-dots-server-discovery/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- Thank you for the work put into this document. It is easy to read. Please find below a couple of blocking DISCUSS points and some non-blocking COMMENT points and some nits. In addition to my own points, please consider Zhen Caos' INT directorate review at: https://datatracker.ietf.org/doc/review-ietf-dots-server-discovery-11-intdir-lc-cao-2020-10-12/ I hope that this helps to improve the document, Regards, -éric == DISCUSS == -- Section 4 -- Trivial to fix: there is no "DHCP lease" for stateless DHCPv6... You should probably rather refer to the information-request refresh time option (section 21.23 of RFC 8415). -- Section 5.1.2 -- I fully second Zhen Cao's review: how will the IPv4-mapped IPv6 address(es) be used? They MUST not appear on the wire and there is a DHCPv4 option to convey the DOTS information. Is it when DHCPv6 is available, no DHCPv4, and only IPv4 connectivity to the DOTS server ? If so, then please clarify the text. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Is DHCP really the way to go ? Even if it seems that there are use cases, relying on dynamic DHCP for such an important security protocol looks very strange to me (as the security AD has approved DHCP use, it is a mere non-blocking comment). Should DNSSEC be required for domain name resolution or is relying only on TLS server authentication enough ? The document gives a lot of IPv6 examples: thank you for this but it also mention multiple address families. Should Happy Eyeball be used when connected to the DOTS server? -- Section 4 -- While this section title is "Unified DOTS Discovery Procedure", I read 3 different mechanisms so apparently conflicting with the section title. Suggest to remove "unified" from the section title. Putting DHCP configuration under explicit configuration appears weird to me as DHCP is rather dynamic and on the same level as DNSD. May I suggest to move the sentence "DOTS clients will prefer information received from the discovery methods in the order listed" before the list? It is an important sentence IMHO. I wonder wheter the sentence "Expiry of a peer DOTS agent's certificate currently in use." is correct... Should it be "agent peer DOTS certificate" ? -- Sections 5.1.3 and 5.2.3-- The part of the sentence "as distinguished by the presence of multiple root labels" should be explained more as it is unclear. -- Section 6 -- Just to say that the use of S-NAPTR surprised me (no need to reply) == NITS == The id-nits tool indicates a non used reference to RFC 8783, so, please clean up the reference list ;-) -- Section 1 -- s/by multi-homed DOTS clients are out of scope/by multi-homed DOTS clients are out of this document scope/ ?

It is easy to read. Please find below a couple of blocking DISCUSS points and some non-blocking COMMENT points and some nits. In addition to my own points, please consider Zhen Caos' INT directorate review at: https://datatracker.ietf.org/doc/review-ietf-dots-server-discovery-11-intdir-lc-cao-2020-10-12/ I hope that this helps to improve the document, Regards, -éric == Previous DISCUSS -- solved by Med Boucadair and kept here for archiving purposes == -- Section 4 -- Trivial to fix: there is no "DHCP lease" for stateless DHCPv6... You should probably rather refer to the information-request refresh time option (section 21.23 of RFC 8415). -- Section 5.1.2 -- I fully second Zhen Cao's review: how will the IPv4-mapped IPv6 address(es) be used? They MUST not appear on the wire and there is a DHCPv4 option to convey the DOTS information. Is it when DHCPv6 is available, no DHCPv4, and only IPv4 connectivity to the DOTS server ? If so, then please clarify the text. == End of previous DISCUSS == Is DHCP really the way to go ? Even if it seems that there are use cases, relying on dynamic DHCP for such an important security protocol looks very strange to me (as the security AD has approved DHCP use, it is a mere non-blocking comment). Should DNSSEC be required for domain name resolution or is relying only on TLS server authentication enough ? The document gives a lot of IPv6 examples: thank you for this but it also mention multiple address families. Should Happy Eyeball be used when connected to the DOTS server? -- Section 4 -- While this section title is "Unified DOTS Discovery Procedure", I read 3 different mechanisms so apparently conflicting with the section title. Suggest to remove "unified" from the section title. Putting DHCP configuration under explicit configuration appears weird to me as DHCP is rather dynamic and on the same level as DNSD. May I suggest to move the sentence "DOTS clients will prefer information received from the discovery methods in the order listed" before the list? It is an important sentence IMHO. I wonder wheter the sentence "Expiry of a peer DOTS agent's certificate currently in use." is correct... Should it be "agent peer DOTS certificate" ? -- Sections 5.1.3 and 5.2.3-- The part of the sentence "as distinguished by the presence of multiple root labels" should be explained more as it is unclear. -- Section 6 -- Just to say that the use of S-NAPTR surprised me (no need to reply) == NITS == The id-nits tool indicates a non used reference to RFC 8783, so, please clean up the reference list ;-) -- Section 1 -- s/by multi-homed DOTS clients are out of scope/by multi-homed DOTS clients are out of this document scope/ ?

Ok, that is better, sorry for missing that part. Still as mDNS results that= that nodes on the network segment or multicast domain used easily can inject ans= wers. So it enlarges the attack surface, but DNS without DNSSEC appears quite sensitive to targeted attacks on the name resolution of the DOTS servers.= =20 I think comparing sections 8.3 and 8.2 is interesting. In 8.2 you are expli= cit about the attackers interest in compromising the S-NAPTR resolution. But th= e same attack potential in DNS-SD is not mentioned.=20 Is redirects allowed here when doing the lookup and does that affect what d= omain name one will use in SNI in DTLS when connecting to the DOTS agent? Just tr= ying to understand if the DTLS connection step is a second line of defence for t= he DNSSD step? In other words that an attacker can inject or modify DNS respon= se to ensure that the DOTS client connects to the attacks server, but that it isn= 't fooled that this is the intended one?=20 Cheers

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 12 Nov 2020 11:19:30 -0000 Reviewer: Dan Romascanu Review result: Has Issues This document specifies the Distributed Denial-of-Service Open Threat Signaling (DOTS) signal channel, a protocol for signaling the need for protection against Distributed Denial-of-Service (DDoS) attacks to a server capable of enabling network traffic mitigation on behalf of the requesting client. The DOTS data channel is defined in an associated document. The document updates RFC 8872. The document is almost Ready from an OPS perspective, but there are a couple of issues worth clarification before approval. 1. Appendix A describes the changes from RFC 8782. I could not find however any information in the document concerning backwards compatibility and the path of upgrade that an operator should be aware about when migrating an existing client, server or the whole network from RFC 8782 support. If I missed it, please point and maybe detail this information in the Appendix. If not, it would be useful to add. 2. I could not find any information about the supplementary overload that the changes in signaling brought by this update may bring. If such an analysis was made, it would be useful to mention its results. No significant extra-load is fine. If anything different, it would be useful to add more details.

We have here 2 applications, very little overlap in functionality using = a common protocol (DOTS/CoAP/(D)TLS) - no real different to say, mail = and web both using a common protocol - TLS. If they insist on a single port, then we would have to do at least one = of a) Use different IP addresses albeit probably on the same host b) De-multiplex incoming data to IP:port and steer to appropriate = application and transmit responses accordingly - a sort of DOTS proxy = front-ending things c) Merge the 2 applications into a single entity and enhance DOTS = protocol d) Spawn off the appropriate instance when a new connection comes in - = but we are UDP here. e) Rely on server (and call-home) discovery to provide an alternative = port. Note that the CoAP library I am using is not multi-thread safe which = complicates things further.

Title : Distributed Denial-of-Service Open Threat Signaling (DOTS) Telemetry Authors : Mohamed Boucadair Tirumaleswar Reddy Ehud Doron Meiling Chen Jon Shallow Filename : draft-ietf-dots-telemetry-14.txt Pages : 107 Date : 2020-11-15 Abstract: This document aims to enrich DOTS signal channel protocol with various telemetry attributes allowing optimal Distributed Denial-of- Service attack mitigation. It specifies the normal traffic baseline and attack traffic telemetry attributes a DOTS client can convey to its DOTS server in the mitigation request, the mitigation status telemetry attributes a DOTS server can communicate to a DOTS client, and the mitigation efficacy telemetry attributes a DOTS client can communicate to a DOTS server. The telemetry attributes can assist the mitigator to choose the DDoS mitigation techniques and perform optimal DDoS attack mitigation.

This draft is a work item of the DDoS Open Threat Signaling WG of the IETF. Title : Distributed-Denial-of-Service Open Threat Signaling (DOTS) Agent Discovery Authors : Mohamed Boucadair Tirumaleswar Reddy Filename : draft-ietf-dots-server-discovery-15.txt Pages : 26 Date : 2020-11-15 Abstract: This document specifies mechanisms to configure Distributed Denial of Service Open Threat Signaling (DOTS) clients with their DOTS servers. The discovery procedure also covers the DOTS Signal Channel Call Home. Knowing the appropriate DOTS server for a given location can be useful to engage mitigation actions even in cases where the DOTS client cannot localize the attack, but only knows that some resources are under attack and that help is needed.

The IESG contact persons are Benjamin Kaduk and Roman Danyliw. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dots-server-discovery/ Technical Summary This document specifies mechanisms to configure Distributed-Denial-of-Service Open Threat Signaling (DOTS) clients with their DOTS servers. The discovery procedure also covers the DOTS Signal Channel Call Home. Working Group Summary The -00 version of the document was published as individual I-D in June 2017. The call for adoption was issued in November 2018 and ended up in March 2019. The WG support for adoption of this draft was steady with quite a lot of suggestions how to improve the document. The draft was fairly well (for this WG) discussed and has been reviewed by active WG members. Document Quality Document authors are also co-authors of core DOTS documents (signal channel, data channel etc.) I believe that they have good understanding of DOTS architecture. There is at least one implementations of this specification.

This draft is a work item of the DDoS Open Threat Signaling WG of the IETF. Title : Distributed Denial-of-Service Open Threat Signaling (DOTS) Signal Channel Specification Authors : Mohamed Boucadair Jon Shallow Tirumaleswar Reddy.K Filename : draft-ietf-dots-rfc8782-bis-02.txt Pages : 120 Date : 2020-11-17 Abstract: This document specifies the Distributed Denial-of-Service Open Threat Signaling (DOTS) signal channel, a protocol for signaling the need for protection against Distributed Denial-of-Service (DDoS) attacks to a server capable of enabling network traffic mitigation on behalf of the requesting client.

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 18 Nov 2020 10:04:14 -0000 A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the DDoS Open Threat Signaling WG of the IETF. Title : Use Cases for DDoS Open Threat Signaling (DOTS) Telemetry Authors : Yuhei Hayashi Meiling Chen Li Su Filename : draft-ietf-dots-telemetry-use-cases-01.txt Pages : 16 Date : 2020-11-18 Abstract: Denial-of-service Open Threat Signaling (DOTS) Telemetry enriches the base DOTS protocols to assist the mitigator in using efficient DDoS- attack-mitigation techniques in a network.

Major change point is as below. - Add Li. Su as co-author. - Add new use case "Unsupervised Machine Learning of Flow Collector" which uses a baseline attribute. I will modify it based on Med's comments. * extract use cases already included in the telemetry I-D * include message bodies with the attributes. Comments or questions are welcome. Thanks, Yuhei ---------- Forwarded message --------- From: Date: 2020=E5=B9=B411=E6=9C=8818=E6=97=A5(=E6=B0=B4) 19:04 Subject: New Version Notification for draft-ietf-dots-telemetry-use-cases-0= 1.txt To: Meiling Chen , Yuhei Hayashi , Li Su A new version of I-D, draft-ietf-dots-telemetry-use-cases-01.txt has been successfully submitted by Yuhei Hayashi and posted to the IETF repository.

I know that at the time of draft adoption you provided this confirmation. Can you, please, re-confirm it for the latest version of the draft. And I'd also like to ask you about implementation status of the draft. I guess that there is at least one implementation of the draft. Am I right? Are there other implementations you are aware of?

This draft contains two YANG modules, ietf-dots-telemetry and module ietf-dots-mapping. Both modules are unusual from a YANG perspective in that they consist of solely typedefs, groupings and sx:structures, and that their purpose is to define message bodies for a domain specific management protocol. Since my previous review of this module (-09, June 2020) the underpinnings of the modules have changed significantly with a new RFC in the works, addressing the fundamental issues pointed out at that time. Very good & impressive. I still think there are important issues to resolve, so I will call the current state of -14 "Almost Ready". Links to previous relevant reviews: https://datatracker.ietf.org/doc/review-ietf-dots-rfc8782-bis-00-yangdoctors-early-aries-2020-09-23/ https://datatracker.ietf.org/doc/review-ietf-dots-telemetry-09-yangdoctors-early-lindblad-2020-06-30/ Because of this hitherto unusual application of YANG, the usual YD review procedures are not really applicable. Whoever reads this should feel free to comment on which perspectives should be included (or not) in an YD review of a YANG module defining a new protocol. I think the YD review should not be expected to cover the usability/interoperability of the newly defined protocol as a whole. E.g. which messages are sent when, what is the relevant/reasonable content in each message, are there any races or scalability issues, etc. IMO, such an analysis is essential, but too much work for an YD review (and outside my area of expertise). I have placed my review focus on the clear interpretation of the YANG modules, since that will be key to interoperability. When YANG is mapped to NETCONF or RESTCONF, there are entire RFCs devoted to describing how that mapping is done, from what "mandatory" actually means in the protocol and how keys are sent, all the way to how the XML or JSON payloads are constructed and potential error messages. A lot more of that mapping is now present in this document, but I still find many aspects that are undefined/unclear. #1 mandatory true A few elements are marked mandatory true in the model. The meaning of this is not defined in the draft. I would expect this means clients as well as servers MUST provide a value for the mandatory element in each message if the parent element exists. This would be like how mandatory elements in YANG actions/rpcs/notifications work (and different from how mandatory works with configuration data in NETCONF/YANG). Section 7.1 states: "DOTS telemetry attributes are optionally signaled and therefore MUST NOT be treated as mandatory fields in the DOTS signal channel protocol." This blanket statement makes things less clear for me. Can I trust the YANG mandatory and key statements to indicate what has to be included, and everything else is optional? If so, I would advise to state just that. #2 key There are many key statements around these modules. The exact meaning of the key keyword in this dots-signal protocol is not defined. Are key sets always unique in a list? Are keys mandatory? Are there any sequencing requirements on keys, e.g. do keys need to be sent first (as in NETCONF) in a list element? Such a requirement may not be unreasonable for servers with limited resources. #3) if-feature The ietf-dots-mapping.yang module defines one YANG feature and a few instances of model statements conditional on it with an if-feature statement. There is a description for how a server advertises support for this specific feature (by including a very particular leaf in one of the messages). From a YANG mapping perspective, it might have been better to have a general mechanism for advertising features. With the current specification, no other features can (ever) be added in a backwards compatible way. #5) augment or sx:augment-structure The draft is using augment (but means sx:augment-structure) and sx:augment-structure. Are implementors allowed to use augment in their implementations? If so, how would a client know if an augmented model is in use? Section 6.1.2 states that servers MUST reject messages when "attribute values are not acceptable". Does that have any implications for augment? #6) deviations Deviations are never mentioned. Are implementors allowed to deviate from the protocol in any way, if declared using deviation statements? If so, how would a client know if a deviated model is in use? #7) config true|false RFC 8791 (which defines sx:structure) expressly states that config true and false statements have no defined meaning and will be ignored in sx:structure. Therefore it's very good that this draft defines behavior for the GET operation with respect to config true and config false elements. Nothing is said about how the config attribute plays with PUT, POST or DELETE however. #8) PATCH Is the PATCH HTTP operation supported in this context? It is never mentioned. If so, it's is unclear how it would work in relation to the protocol HTTP headers, the tsid mechanism and the YANG mandatory concept. If not, that might be good to point out somewhere. #9) Payload encoding references As far as I understand, the message payloads are meant to be encoded in JSON or CBOR. This draft has no references to the relevant documents describing these encodings (https://tools.ietf.org/html/rfc7951 and https://tools.ietf.org/html/draft-ietf-core-yang-cbor-13). And now a few minor comments on particular points or wordings. #10) The tree diagram in Fig. 30 is not using the correct format (see the other tree diagrams). #11) Section 6.3.1 states "The overlapped lower numeric 'tsid' MUST be automatically deleted and no longer be available." Since this mechanism is a central part of the protocol, I would think specifying exactly what "overlapped" means would improve interoperability. #12) Section 6.3.1 states "If no target clause is included in the request, this is an indication that the baseline information applies for the DOTS client domain as a whole." Define "target clause" (= tsid?) #13) Section 4.5 states "The use of "identities" is thus suboptimal from a message compactness standpoint." Clearly, but they excel in forward extensibility. There may be cases where the identities would be better and even more compact than an alternative solution without them. To rule out all use of identities based on a blanket statement like this does not seem like a good design practice. I suggest to remove this sentence. #14) In the YANG, there is a choice with a single case "case server-to-client-only". This way of using choice is a little unusual, but it works. #15) In the YANG, there is a list telemetry without any key. This is allowed for config false lists in NETCONF/YANG, and it could be allowed in this protocol. For a constrained device, however, this situation may not be ideal. Without a key, the only way for a client to read this information is to read it all at once. If that is the only reasonable use case for this information, you kan keep it as is. If this data may be large, a different way of modeling may be in order so that data could be requested a little at a time. #16) Section 6.1.1 states " 'server-originated-telemetry' under 'max-config-values' to 'true' ('false' is used otherwise). If 'server-originated-telemetry' is not present in a response, this is equivalent to receiving a request with 'server-originated-telemetry' set to 'false'. " In YANG, this is usually expressed by adding "default false" to the leaf. #17) There are many leafs in the models that have no default, no mandatory and no description which tells what happens if the leaf is not provided. E.g. what happens if "query-type" is not specified? #18) Many lists have "unit" as a key. This can work, but is an unusual choice. It opens up for sending the same information several times over with different units. #19) Section 7.1.1 states "At least one of the attributes 'target-prefix', 'target-fqdn', 'target-uri', 'alias-name', or 'mid-list' MUST be present in the target definition." This may be a good thing to add in a must-statement, or at least in a description statement in the module. #20) Section 7.1.1 mentions a "optional subattribute" Please define this term, or change to a defined term. #21) leaf-list alias-name {type string; description "An alias name that points to a resource."; Unclear; what is a resource here? What is the format of the string? Could this be a leafref? #22) There are typedefs called "unit-type" and "unit". I would suggest changing at least one of those names so that readers have a chance at understanding how they differ. Also, some of their content overlaps, so maybe one could incorporate the other? #23) Similarly for grouping percentile-config and grouping percentile. Names that better reflect their content and usage would be good. #24) There are still a few instances of augment in the model. They should be sx:augment-stucture. #25) I didn't go through the entire table in section 11, but I looked at a few random leafs from the model. A couple seem to be missing in section 11, e.g. last-updated and rate-limit. Maybe good to go through the latest version to really check that all relevant elements are listed. >< From nobody Thu Nov 26 03:40:18 2020 Return-Path: X-Original-To: dots@ietfa.amsl.com Delivered-To: dots@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 0BF6A3A125C for ;

People have realized that a formal message definition that can be integrated into the tool chain is much better than 100 pages of ASCII art. Augments, annotations, and deviations are not only possible, but critical to deployment. But you are raising an important point -- it is difficult to review groupings without any context.

Reviewer: Jan Lindblad
Review result: Almost Ready

Dear Dots Authors, NETMOD WG,

This is my YD LC review of draft-ietf-dots-telemetry-14. This draft contain= s
two YANG modules, ietf-dots-telemetry and module ietf-dots-mapping. Both modules are unusual from a YANG perspective in that they consist of solely<= br> typedefs, groupings and sx:structures, and that their purpose is to define<= br> message bodies for a domain specific management protocol.



This is consistent with= the intent of RFC 8791.

People have realized that= a formal message definition that can be integrated
into the tool= chain is much better than 100 pages of ASCII art.=C2=A0 Augments,
annotations, and deviations are not only possible, but critical to deploy= ment.

But you are raising an important point -- it= is difficult to review groupings without any context.
(Without a= ny "uses").

Since my previous review of this module (-09, June 2020) the underpinnings = of
the modules have changed significantly with a new RFC in the works, address= ing
the fundamental issues pointed out at that time. Very good & impressive= . I
still think there are important issues to resolve, so I will call the curre= nt
state of -14 "Almost Ready".

Links to previous relevant reviews:

Because of this hitherto unusual application of YANG, the usual YD review procedures are not really applicable. Whoever reads this should feel free t= o
comment on which perspectives should be included (or not) in an YD review o= f a
YANG module defining a new protocol.

I think the YD review should not be expected to cover the
usability/interoperability of the newly defined protocol as a whole. E.g. w= hich
messages are sent when, what is the relevant/reasonable content in each
message, are there any races or scalability issues, etc. IMO, such an analy= sis
is essential, but too much work for an YD review (and outside my area of expertise). I have placed my review focus on the clear interpretation of th= e
YANG modules, since that will be key to interoperability.



Agreed.=C2=A0 The proto= col document review is a separate matter.

=C2=A0
When YANG is mapped to NETCONF or RESTCONF, there are entire RFCs devoted t= o
describing how that mapping is done, from what "mandatory" actual= ly means in
the protocol and how keys are sent, all the way to how the XML or JSON payl= oads
are constructed and potential error messages. A lot more of that mapping is= now
present in this document, but I still find many aspects that are
undefined/unclear.

But this is related = to the message encoding, not the YANG definitions.
YANG is (tryin= g to be) encoding-independent, and the YANG to CBOR and SID drafts explain<= /div>
how to encode any type of YANG data in CBOR.

=

#1 mandatory true=C2=A0

A few elements are marked mandatory true in the model. The meaning of this = is
not defined in the draft. I would expect this means clients as well as serv= ers
MUST provide a value for the mandatory element in each message if the paren= t
element exists. This would be like how mandatory elements in YANG
actions/rpcs/notifications work (and different from how mandatory works wit= h
configuration data in NETCONF/YANG).

Section 7.1 states: "DOTS telemetry attributes are optionally signaled= and
therefore MUST NOT be treated as mandatory fields in the DOTS signal channe= l
protocol." This blanket statement makes things less clear for me. Can = I trust
the YANG mandatory and key statements to indicate what has to be included, = and
everything else is optional? If so, I would advise to state just that.

#2 key

There are many key statements around these modules. The exact meaning of th= e
key keyword in this dots-signal protocol is not defined. Are key sets alway= s
unique in a list? Are keys mandatory? Are there any sequencing requirements= on
keys, e.g. do keys need to be sent first (as in NETCONF) in a list element?=
Such a requirement may not be unreasonable for servers with limited resourc= es.

#3) if-feature

The ietf-dots-mapping.yang module defines one YANG feature and a few instan= ces
of model statements conditional on it with an if-feature statement. There i= s a
description for how a server advertises support for this specific feature (= by
including a very particular leaf in one of the messages). From a YANG mappi= ng
perspective, it might have been better to have a general mechanism for
advertising features. With the current specification, no other features can=
(ever) be added in a backwards compatible way.

#5) augment or sx:augment-structure

The draft is using augment (but means sx:augment-structure) and
sx:augment-structure. Are implementors allowed to use augment in their
implementations? If so, how would a client know if an augmented model is in=
use? Section 6.1.2 states that servers MUST reject messages when "attr= ibute
values are not acceptable". Does that have any implications for augmen= t?

#6) deviations

Deviations are never mentioned. Are implementors allowed to deviate from th= e
protocol in any way, if declared using deviation statements? If so, how wou= ld a
client know if a deviated model is in use?

#7) config true|false

RFC 8791 (which defines sx:structure) expressly states that config true and=
false statements have no defined meaning and will be ignored in sx:structur= e.
Therefore it's very good that this draft defines behavior for the GET o= peration
with respect to config true and config false elements. Nothing is said abou= t
how the config attribute plays with PUT, POST or DELETE however.

#8) PATCH

Is the PATCH HTTP operation supported in this context? It is never mentione= d.
If so, it's is unclear how it would work in relation to the protocol HT= TP
headers, the tsid mechanism and the YANG mandatory concept. If not, that mi= ght
be good to point out somewhere.

#9) Payload encoding references

As far as I understand, the message payloads are meant to be encoded in JSO= N or
CBOR. This draft has no references to the relevant documents describing the= se
encodings (https://tools.ietf.org/html/rfc7951 and
https://tools.ietf.org/html/draft-ietf-core-= yang-cbor-13).

And now a few minor comments on particular points or wordings.

#10) The tree diagram in Fig. 30 is not using the correct format (see the o= ther
tree diagrams).

#11) Section 6.3.1 states "The overlapped lower numeric 'tsid'= MUST be
automatically deleted and no longer be available." Since this mechanis= m is a
central part of the protocol, I would think specifying exactly what
"overlapped" means would improve interoperability.

#12) Section 6.3.1 states "If no target clause is included in the requ= est, this
is an indication that the baseline information applies for the DOTS client<= br> domain as a whole." Define "target clause" (=3D tsid?)

#13) Section 4.5 states "The use of "identities" is thus sub= optimal from a
message compactness standpoint." Clearly, but they excel in forward extensibility. There may be cases where the identities would be better and = even
more compact than an alternative solution without them. To rule out all use= of
identities based on a blanket statement like this does not seem like a good=
design practice. I suggest to remove this sentence.

#14) In the YANG, there is a choice with a single case "case
server-to-client-only". This way of using choice is a little unusual, = but it
works.

#15) In the YANG, there is a list telemetry without any key. This is allowe= d
for config false lists in NETCONF/YANG, and it could be allowed in this
protocol. For a constrained device, however, this situation may not be idea= l.
Without a key, the only way for a client to read this information is to rea= d it
all at once. If that is the only reasonable use case for this information, = you
kan keep it as is. If this data may be large, a different way of modeling m= ay
be in order so that data could be requested a little at a time.

#16) Section 6.1.1 states " 'server-originated-telemetry' unde= r
'max-config-values' to 'true' ('false' is used othe= rwise).=C2=A0 If
'server-originated-telemetry' is not present in a response, this is= equivalent
to receiving a request with 'server-originated-telemetry' set to &#= 39;false'. " In
YANG, this is usually expressed by adding "default false" to the = leaf.

#17) There are many leafs in the models that have no default, no mandatory = and
no description which tells what happens if the leaf is not provided. E.g. w= hat
happens if "query-type" is not specified?

#18) Many lists have "unit" as a key. This can work, but is an un= usual choice.
It opens up for sending the same information several times over with differ= ent
units.

#19) Section 7.1.1 states "At least one of the attributes 'target-= prefix',
'target-fqdn', 'target-uri', 'alias-name', or '= mid-list' MUST be present in the
target definition." This may be a good thing to add in a must-statemen= t, or at
least in a description statement in the module.

#20) Section 7.1.1 mentions a "optional subattribute" Please defi= ne this term,
or change to a defined term.

#21) leaf-list alias-name {type string; description "An alias name tha= t points
to a resource."; Unclear; what is a resource here? What is the format = of the
string? Could this be a leafref?

#22) There are typedefs called "unit-type" and "unit". = I would suggest changing
at least one of those names so that readers have a chance at understanding = how
they differ. Also, some of their content overlaps, so maybe one could
incorporate the other?

#23) Similarly for grouping percentile-config and grouping percentile. Name= s
that better reflect their content and usage would be good.

#24) There are still a few instances of augment in the model. They should b= e
sx:augment-stucture.

#25) I didn't go through the entire table in section 11, but I looked a= t a few
random leafs from the model. A couple seem to be missing in section 11, e.g= .
last-updated and rate-limit. Maybe good to go through the latest version to=
really check that all relevant elements are listed.

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 27 Nov 2020 14:21:38 -0000 Hi Valery, I support these changes as well. Supporting the current- variants makes good sense to me for telemetry reporting - especially when early on into an attack the percentile- information has not had enough time to necessarily give meaningful = values and the attack may have already started to drop away from the peak- = values. Implementations may also find it easier to report on current- and peak- = than spend time on computing percentiles which requires extra CPU time and = RAM storage for the interim holding of samples. Extending the list of enums as to the scaling of the reported values, = while I trust that we will not see DDoS attacks of this scale, there is that future potential possibility, so adding in enums for peta, exa and zetta scaling would be useful to do now.

Reviewer: Jan Lindblad<= br> Review result: Almost Ready

Dear Dots Authors, NETMOD WG,

This is my YD LC review of draft-ietf-dots-telemetry-14. This draft contain= s
two YANG modules, ietf-dots-telemetry and module ietf-dots-mapping. Both modules are unusual from a YANG perspective in that they consist of solely<= br> typedefs, groupings and sx:structures, and that their purpose is to define<= br> message bodies for a domain specific management protocol.

=C2=A0

=C2=A0

This is consistent with the intent of RFC 8791.

=C2=A0

People have realized that a formal message definitio= n that can be integrated

into the tool chain is much better than 100 pages of= ASCII art.=C2=A0 Augments,

annotations, and deviations are not only possible, b= ut critical to deployment.

=C2=A0

But you are raising an important point -- it is diff= icult to review groupings without any context.

(Without any "uses").

=C2=A0

Since my previous revie= w of this module (-09, June 2020) the underpinnings of
the modules have changed significantly with a new RFC in the works, address= ing
the fundamental issues pointed out at that time. Very good & impressive= . I
still think there are important issues to resolve, so I will call the curre= nt
state of -14 "Almost Ready".

Links to previous relevant reviews:
https://datatracker= .ietf.org/doc/review-ietf-dots-rfc8782-bis-00-yangdoctors-early-aries-2020-= 09-23/
https://datatracke= r.ietf.org/doc/review-ietf-dots-telemetry-09-yangdoctors-early-lindblad-202= 0-06-30/

Because of this hitherto unusual application of YANG, the usual YD review procedures are not really applicable. Whoever reads this should feel free t= o
comment on which perspectives should be included (or not) in an YD review o= f a
YANG module defining a new protocol.

I think the YD review should not be expected to cover the
usability/interoperability of the newly defined protocol as a whole. E.g. w= hich
messages are sent when, what is the relevant/reasonable content in each
message, are there any races or scalability issues, etc. IMO, such an analy= sis
is essential, but too much work for an YD review (and outside my area of expertise). I have placed my review focus on the clear interpretation of th= e
YANG modules, since that will be key to interoperability.

=C2=A0

=C2=A0

Agreed.=C2=A0 The protocol document review is a sepa= rate matter.

=C2=A0

=C2=A0

When YANG is mapped to NETCONF or RESTCONF, there ar= e entire RFCs devoted to
describing how that mapping is done, from what "mandatory" actual= ly means in
the protocol and how keys are sent, all the way to how the XML or JSON payl= oads
are constructed and potential error messages. A lot more of that mapping is= now
present in this document, but I still find many aspects that are
undefined/unclear.

=C2=A0

But this is related to the message encoding, not the= YANG definitions.

YANG is (trying to be) encoding-independent, and the= YANG to CBOR and SID drafts explain

how to encode any type of YANG data in CBOR.<= u>
