P802.1CQ contributions and discussions

Antonio de la Oliva presented MAC Address Acquisition Protocol https://mentor.ieee.org/omniran/dcn/19/omniran-19-0011-01-CQ00-maap-introduction.pptx

  • The MAC Address Acquisition Protocol (MAAP), specified in IEEE Std 1722, has been investigated and considered to be reused for both multicast and unicast address assignment in P802.1CQ.
  • A verbal update was provided on the current status of the IEEE 1722 WG. The TG discussed both the use of MAAP in the professional audio market and the rationale for multicast to be addressed in the scope of P802.1CQ.
  • The TG discussed the idea of adopting MAAP in P802.1CQ for self-claiming address assignment in both wired and wireless media, but certain changes may be needed, e.g. the frame encapsulation;
  • It was noted that the EtherType used for MAAP belongs to Harman International.

Disposition: The investigation regarding IEEE 1722 will be presented to the TSN TG on March 12, 2019. The OmniRAN TG will decide how to proceed regarding the adoption of MAAP afterwards.

Tuesday 12 March 2019

The TG Chair led a discussion on the purpose of ISO/IEC JTC1 processing of 802.1 standards, and the current status.

  • FDIS pre-ballots on 802.1AE-Rev, 802.1Q-Rev, 802.1Xck closed March 11, 2019 and were to be discussed (if available) in the Maintenance TG on March 12, 2019.
  • Discussion also continued Wednesday PM.

Disposition: The ballots passed, the comments received on the ballots are in Comments on pre-ballots in ISO/IEC JTC1 SC6 http://www.ieee802.org/1/files/public/docs2019/maint-randall-SC6comments1Q1XckAE-0319-v1.pdf

A.O.B.

Mick Seaman presented Running with scissors: Cut-through in bridged networks http://www.ieee802.org/1/files/public/docs2019/new-seaman-cut-through-scissors-0119-v01.pdf.

  • Discussion of potential security exposures as per section 3 of the document. Further exposures could be expected.
  • Reaffirmed that all Cipher Suites used by MACsec provide protection against known plain text attacks.

Disposition: Further discussion expected if 802.3 and the TSN TG proceed with cut-through related projects.

IEEE 802.1AE-2018 Corrigendum

The TG Chair led a discussion on the proposed P802.1AE-2018/Cor 1
http://www.ieee802.org/1/files/public/docs2019/ae-cor1-draft-par-0319-v00.pdf corrigendum PAR.

Disposition: Agreed (non-dissenting) to present to the Maintenance TG and request forwarding to NesCom.

Traffic flow privacy

Don Fedyk presented Ethernet-Traffic Flow Security
http://www.ieee802.org/1/files/public/docs2019/new-fedyk-traffic-flow-security-0219.pdf.

  • The TG Chair suggested that this work might be best progressed as an amendment to IEEE Std 802.1AE-2018.
  • The envisaged functionality would be additional (and potentially separable) “Privacy enhancement” capability to be used in conjunction with (rather than as a change to MACsec).
  • The scope of work could include development of an informative “Privacy Considerations” annex based on Privacy considerations in bridged networks
    http://www.ieee802.org/1/files/public/docs2018/e-seaman-privacy-in-bridged-networks-1018-v01.pdf as this would provide useful background, as well as address the issue of where to place such material (it being impractical to engage in multiple projects to add privacy considerations to all 802.1 standards, as well as there being a need to assess privacy as a function of using standards in combination with each other).
  • The need for managed objects might be best addressed by YANG, as a new MIB or extensions to the existing MIB would be unlikely to be used. This would necessitate creating a YANG model for the existing 802.1AE functionality, based on the existing IEEE Std 802.1AE-2018 Figure 10-5 SecY managed objects UML (and not on conversion of the existing MIB).

Disposition: Discussion to be continued Tuesday PM.

Tuesday March 12, 2019

10:30 AM (call to order by the TG Chair) to 12:30 PM

P802E Privacy (Recommended Practice … for 802 …)

Jerome Henry, P802E editor, led the resolution of comments received in the TG ballot on http://www.ieee802.org/1/files/private/802-e-drafts/d1/802E-d1-3.pdf based on

  • Editor report: Comment Resolution for 802.1 TG Ballot D 1.3 (as of 03/12/2019) http://www.ieee802.org/1/files/private/802-e-drafts/d1/802E-d1-3-editor-report.pdf
  • Initial Disposition of Working Group Ballot Comments on IEEE Draft P802E-Rev-D1.3 http://www.ieee802.org/1/files/private/802-e-drafts/d1/802E-d1-3-pdis1.pdf
    • This initial disposition showed (incorrectly) the ballot as a WG ballot, and recorded passed/failed (not applicable at TG ballot) accordingly.
    • Refinements to this initial disposition to be incorporated in the next draft and a revised disposition.
  • Clarified in discussion of comment 296 that a threat model is a process by which threats are identified, and as such the entire document comprises the threat model. Text to be added by the editor as a new clause 1.3 to make that point, offline input from the TG welcomed.
  • Next draft to be forwarded for IETF coordination (via Dorothy Stanley) as agreed in the November 2018 coordination meeting.
  • No work directly on P802E in the May 2019 802.1 interim session. WG ballot of next draft to be made available through the normal 802.1 process for soliciting comments from other WGs, with ballot resolution during the July 2019 802.1 plenary session.

Disposition: Agreed (informally, none dissenting) to request permission to proceed to WG ballot with the next draft.

3:30 PM (call to order by the TG Chair) to 5:00 PM

Traffic flow privacy

Don Fedyk presented Ethernet-Traffic Flow Security
http://www.ieee802.org/1/files/public/docs2019/new-fedyk-traffic-flow-security-0219.pdf.

  • Continuation of Tuesday PM discussion, focusing on the “Traffic Flow Security Requirements” in the document.
  • Discussion of a potential “privacy shim” and accompanying frame formats. Frame format to be self-identifying, i.e., correct decoding would not depend on any mode setting negotiated between transmitter and receivers(s). Options available to transmitter to choose extent to which traffic analysis could be protected against, e.g. fixed frame sizes with padding, packing original frames in larger frame, padding at front of frame before including a frame (or between frames included in outer frame). Small number of options to be described to allow for clarity in describing implementation capabilities to user, not restricting more complex strategies (e.g., making flow characteristics appear like the known characteristics of a different flow).
  • Fragmentation of an original frame across an encapsulating frame (necessitating reassembly) likely to be the most controversial suggestion. Though reassembly not necessarily mandatory, may result in usual ‘any option in standard becomes mandatory to implement’. Partitioning privacy enhancement from MACsec encryption as a clean shim means more information to be carried in privacy enhancement to ensure correct reassembly. May be some view that fragmentation/reassembly capability should be left to similar IP project. Needs WG discussion.
  • Will be interest from MACsec implementers not attending 802 meetings. Need outreach activity to those implementers.
  • Prepare further information and detail to begin 802.1 discussion in May 2019. Potential request to develop a PAR in July 2019, with PAR development during the September 2019 802.1 interim session.

Disposition: For further discussion in teleconferences and during the May 2019 802.1 interim session.

Wednesday March 13, 2019

9:00 AM (call to order by the TG Chair) to 12:00 PM

Mick Seaman, P802.1X-Rev editor, led the resolution of comments received in the WG ballot on http://www.ieee802.org/1/files/private/x-rev-drafts/d1/802-1X-rev-d1-0.pdf.

  • Initial disposition of comments showing the comments received: Proposed Disposition of the Working Group Ballot on IEEE Draft Standard P802.1X-Rev/D1.0 http://www.ieee802.org/1/files/private/x-rev-drafts/d1/802-1X-rev-d1-0-pdis00.pdf
  • The WG ballot passed (100% Approve, 80% Response)
  • A number of comments were simple editorial and could be dealt with by the editor. Comment 79 was discussed, no change to the proposed disposition at this time, but follow up with the commenter required.
  • A large number of comments were directed at the YANG model introduced by the 802.1Xck amendment. In general, these were directed at a very tight specification of the model, as opposed to a looser, more embracing, definition with the use of deviation/refinement for managing specific items of equipment. In general, the tighter definition was viewed favorably.
  • Some of the comments, specifically those on timer values, suggested that the base specification be changed to fit the past MIB and past/future YANG capabilities. This would be a deviation from past practice, where the base specification takes precedence of restriction and description in the MIB. Changes to timer values/ranges would require careful consideration. Some discussion on the adequacy or otherwise of timer value ranges considering the wide range of equipment types to be managed.
  • Detailed discussion of restriction of the UTF-8 alphabet in strings. Not considered culturally sensitive.

Disposition: For further discussion in teleconferences, with goal of completing WG recirculation ballot before the July 2019 802.1 plenary.

Jordon Woods, 60802 editor, led a discussion on the structure of the 60802 conformance clause.

The 60802 Chair proposed to document the high-level principles for the essence of 60802 then give license to the editor to implement these principles in 60802 as he sees best fit. The IEC/IEEE 60802 Joint Project agreed to this approach.

Jordon Woods, 60802 editor, drafted the following high-level 60802 principles together with the IEC/IEEE 60802 Joint Project during the session:

  1. The 60802 standard shall explicitly identify which parts (clauses, subclauses, figures, lists, tables, etc.) of the cited standards apply to this profile.
  2. The features of any cited standard that are mandatory, optional, excluded, or not applicable shall be explicitly identified.
  3. Additional constraints for features of any cited standard shall be identified.

The IEC/IEEE 60802 Joint Project agreed to these 60802 principles that were to be recorded in the resolution of comment #579 in http://ieee802.org/1/files/private/60802-drafts/d1/60802-d1-0-pdis-v03.pdf.

  • Mick Seaman, Independent
  • Jodi Haasz, IEEE Standards Staff Liaison for 802.1

Tuesday March 13, 2019

6:10 PM (call to order by the YANGsters Chair) to 7:25 PM

The YANGsters acting Chair presented the IEEE-SA PatCom Patent Slides for Standards Development Meetings https://development.standards.ieee.org/myproject/Public/mytools/mob/slideset.pdf, the IEEE 802 Participation slide https://mentor.ieee.org/802-ec/dcn/17/ec-17-0093-05-0PNP-ieee-802-participation-slide-ppt.ppt, and made the “Call for Potentially Essential Patents”. There were no responses to the call prior to the end of the week’s meeting.

The YANGsters acting Chair presented the agenda in http://www.ieee802.org/1/files/public/docs2019/yangsters-smansfield-vancouver-agenda-v02.pdf.

Disposition: The agenda was reviewed, discussed and approved.

The YANGsters acting Chair led the Management Address Grouping (.1Qcx) Comment discussion.

  • The latest version of the solution is not the one reflected in the minutes of the YANGsters teleconference held in February 2019.
  • The latest CFM YANG data model incorporates needed changes.

Disposition: The current proposal was discussed pre-meeting and presented at the meeting. The YANG snippets for the most up-to-date solution are in Management Address Grouping (.1Qcx) suggested solution http://www.ieee802.org/1/files/public/docs2019/yangsters-kehrer-management-address-grouping-0319-v01.pdf and also on GitHub at https://github.com/YangModels/yang/blob/master/standard/ieee/draft/802.1/ieee802-dot1q-cfm.yang.

The YANGsters acting Chair summarized information about the IETF Module on Ether[T]ypes.

Disposition: Deferred to a future YANGsters teleconference or meeting.

The YANGsters acting Chair summarized information about, then led a discussion on the IEEE Website for YANG modules and on YANG Catalog Issues. Questions were raised during discussion.

  • Should YANG modules be provided as files on the IEEE 802.1 website (https://1.ieee802.org/) or should they only be linked on GitHub (https://github.com/YangModels/yang/tree/master/standard/ieee/published/802.1)?
    • The “published” folder on GitHub is more useful for developers.
    • The copy on the IEEE server is needed to have a source that is directly under IEEE control.
  • Is it intended to keep all the published versions of the models on the IEEE website (and on GitHub)? If so, how can the different versions be identified?
    • Concerns were raised that adding the date to the filename is redundant information that could introduce additional errors/mismatches. Should this approach be taken? This approach might be necessary for putting the YANG modules on the IEEE website.

Disposition: More discussion needed. An overview figure of how all the bits and pieces fit together (i.e. GitHub, IEEE website, published IEEE document…) will be produced to facilitate the discussion and help decide. YANGsters need to clarify the process before they can define how to name files, how to keep them on the IEEE website and GitHub, etc.: this is a topic to be discussed on future YANGsters teleconference or meeting, the result of which should result in a process description.

The YANGsters acting Chair summarized information about, then led a discussion on the IEEE Open Source Initiative.

Disposition: More detailed information on the current situation is planned to be provided in the YANGsters monthly teleconference in April 2019.

Future meetings/teleconferences

Agreed (informally, none dissenting) to put forward a motion in the closing plenary session to authorize YANGsters to hold monthly teleconferences on the last Tuesday of every month, starting Tuesday March 26, 2019 and ending Tuesday June 25, 2019.

A.O.B.

No other business was discussed in this meeting.
