Tuesday 17 September 2019

8:05 AM call to order by the TG Chair

The Maintenance Task Group Chair, Paul Congdon, presided and wrote the minutes.

At the beginning of the meeting the TG 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 meeting.

The TG Chair:

Karen Randall led a review of the JTC1/SC6 status and pre-ballot responses for IEEE Std 802.1AE and IEEE Std 802.1Xck in http://www.ieee802.org/1/files/public/docs2019/maint-congdon-session-0919-v01.pdf.

Disposition: The 802.1 WG Chair was reminded to send the responses. The meeting agreed (none dissenting) to hold off sending IEEE Std 802.1X-Rev to SC6 until IEEE Std 802.1Xck is complete.

Norman Finn presented Why the EPD/LPD information in IEEE 802, IEEE 802.1AC, and 802.1Q must be fixed http://www.ieee802.org/1/files/public/docs2019/maint-finn-epd-lpd-errors-0919-v02.pdf and led a discussion about inconsistencies in 802 standards with EtherType Protocol Discrimination (EPD) and LLC Protocol Discrimination (LPD).

Disposition: The meeting agreed (none dissenting) to continue the discussion and propose maintenance items against IEEE Std 802.1AC and possibly IEEE Std 802.1Q. It was suggested that IEEE Std 802 is consistent, and no changes are needed. Future contributions are expected.

Future meetings/teleconferences

The TG intends to hold a teleconference (as approved in July 2019) on Tuesday November 05, 2019 at 8:00 AM Pacific, unless cancelled prior to the call.

The TG meets face-to-face next at the November 2019 plenary session.

P802.1X-Rev D1.4 Initial Standards Association Ballot Resolution

Mick Seaman, P802.1X-Rev editor, led the resolution of comments received on http://www.ieee802.org/1/files/private/x-rev-drafts/d1/802-1X-rev-d1-4.pdf.

  • The ballot passed with 97% approval and 84% response rate.
  • Comment resolution started.
  • 10:15 – 10:45 AM recess
  • Comment resolution continued.
  • 12:15 – 1:45 PM recess
  • Minor strictly non-technical editorials (duplicate period, missing ‘s’ on obvious plural, missing bracket, out of date hyperlink) provided to the editor off-line were discussed. These could be covered by the normal copy-editing process.

Disposition: The results of the discussion, as updated during the course of the meeting, are captured in Proposed Disposition of initial Sponsor Ballot comments http://www.ieee802.org/1/files/private/x-rev-drafts/d1/802-1X-Rev-d1-4-sponsor-pdis1.pdf. The response to comment i-2 required provision of detailed references. This was completed by the editor in Disposition of initial Sponsor Ballot comments http://www.ieee802.org/1/files/private/x-rev-drafts/d1/802-1X-Rev-d1-4-sponsor-dis.pdf for final approval in a future teleconference.

Disposition: The document could be used to check our mutual understanding of project goals in PAR and CSD preparation.

4:50 PM recess

Tuesday 17 September 2019

1:40 PM call to order by the TG Chair

MAC Privacy protection

The TG Chair led the review of the draft PAR http://www.ieee802.org/1/files/public/docs2019/dk-seaman-mac-privacy-protection-draft-par-0519-v00.pdf for proposed P8021AEdk Standard for Local and metropolitan area networks-Media Access Control (MAC) Security Amendment 4: Media Access Control (MAC) Privacy protection as initially developed in the May 2019 interim session.

Disposition:

2:55 – 3:30 PM recess

Don Fedyk presented IEEE 802.1AE Yang Statistics http://www.ieee802.org/1/files/public/docs2019/dk-fedyk-dot1ae-statistics-discussion-0917-v01.pdf.

  • This was part of an effort to understand how the existing 802.1AE functionality should be modeled in YANG, as a prelude to modeling MAC Privacy protection.
  • A concern was a multiplication of the number of counters required, as a consequence of using the IETF YANG interface as a base type.

Disposition: The existence of many counters in if:interface cannot be allowed to dictate the fine substructuring (through use of the ISS and EISS for shims, for example) in 802.1 standards. A simpler base type may need to be used where counters would otherwise be duplicated (on the internal port of the S-component of and EDE-CS, for example). Use of augment to construct an entire interface stack form a single base if:interface would also reduce the number of inherited counters in many cases, though clarification as to where in the stack the if:interface counts matched the model would be required. In many cases a SecY model would augment a Bridge Port.

5:25 PM recess

Wednesday 18 September 2019

9:15 AM call to order by the TG Chair

Any Other Business

The TG Chair led short discussions of:

  • The degree to which YANG should follow the detailed internal structure of 802.1 standards, as the general rule that the model need only be followed to the extent that a valid implementation exhibited the same external behavior could be compromised by management observation and control over internal detail.
  • Potential modification of the 802.1X MKA CP state machine to minimize the period for which connectivity was interrupted when the Key Server changed. The change might not be acted upon until the new Key Server distributed SAKs.
  • The effect of cut-through on MACSec. In particular it was considered important not to forward any part of a protected frame until the ICV had been validated. Doing so could allow an attacker to recover the SAK (data key).

Disposition: Further discussion and input would be welcomed on these topics.

Future meetings/teleconferences

Agreed (informally, none dissenting) to hold teleconferences for progression of work as identified during this session and to address TG matters arising, subject to the usual required notice. P802E WG recirculation ballot processing will be addressed by teleconference prior to the November 2019 plenary session, to allow for a further WG recirculation ballot if necessary. The single comment received so far on P802.1AE-2018-Cor1 was an editorial comment on a hyperlink in the boilerplate material. If there are no further comments a teleconference call on this subject will not be necessary.

The TG will meet during the November 2019 plenary session.

9:45 AM adjournment

Time-Sensitive Networking Task Group

Disposition:.As no amendments were proposed to the agenda, it was approved.

Future Directions

Study Item: Managed LAN as a Service [MLaaS]

Wei Qiu presented LAN Trends and Managed LAN Services https://mentor.ieee.org/802.1/dcn/19/1-19-0070-03-ICne-lan-trends-and-managed-lan-services.pptx updating the plan and schedule for a proposed new Nendica Work Item.

Disposition:

  • The Nendica Chair clarified the process for a new PAR, and explained that for a Nendica Work Item it is similar but less formal. The proposal should nevertheless be precirculated to the IEEE 802 Executive Committee, preferably (in the view of the Chair) at least 30 days in advance of an 802 plenary session, as a PAR would be. 802.1 approval needed to be clarified.
  • In contrast to the proposed schedule indicating “report approval in July 2021”, the chartered existence of Nendica is currently until March 2021 and it would be better to plan to complete the report within the existing charter.
  • The Nendica Chair requested indication of any proposed teleconferences needed for the period until the November 2019 plenary meeting.

Paul Congdon presented LAN Technology Directions and Opportunities for Managed Services https://mentor.ieee.org/802.1/dcn/19/1-19-0070-03-ICne-lan-trends-and-managed-lan-services.pptx including trends in LAN management architecture as it evolves from traditional IT to a fully SDN- and cloud-based centralized forwarding architecture managed via cloud-based service enabling simplifying scaling and leading towards virtualization in the LAN.

  • It was clarified that the 320 MHz bands in the slide are actually channels.
  • It was suggested that MLaaS may introduce additional risk in security for the service provider and to a large extent more severe requirements to protect the infrastructure itself.
  • There were discussions about the edge of “End to End” SLAs.
  • Comparisons were made to factory networks which may require more complex stream management capabilities. There is a need to consider how to maintain services in critical operation instances within factories.
  • It was suggested that tools needed for managed LAN require new types of knowledge and that requirements for new types of tools are not known.
  • It was indicated that different vendors may implement standardized solutions but these would lack interoperability, hence the need to develop a profile for managed LAN.
  • Question arose on the time synchronization requirements for IEEE 802.11 WLA and whether there is a need to extend the scope of synchronization.
  • At this stage what P802.11be requires in terms of synchronization is unknown. Nevertheless, it is certain that something is needed there.
  • It was further indicated service providers may not be alone in needing to manage the LAN.

Disposition: Further discussion needed.

Future Meetings

Nendica will meet during the November 2019 plenary session. Two hours on Tuesday evening have been proposed, along with two hours later in the week.

The meeting agreed (none dissenting) to schedule a teleconference October 31, 9:00 AM to 11:00 AM US Eastern (Focus: “Managed LAN as a Service” Study Item).

Any Other Business

No further business was discussed in this session.

11:46 AM adjournment

YANGsters

The acting YANGsters Chair, and YANGsters Secretary, Stephan Kehrer, presided and wrote the minutes.

Tuesday 17 September 2019

6:05 PM call to order by the acting YANGsters Chair

The acting YANGsters 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 acting YANGsters Chair presented the agenda in http://www.ieee802.org/1/files/public/docs2019/yangsters-smansfield-meeting-26-agenda-0919-v01.pdf.

  • An additional topic was raised on the question how much logic should go into IEEE 802.1 YANG modules and whether all mechanisms YANG provides need to be used. This was highlighted especially since implementations behind the models have to take the complexity into account.
  • It was suggested that there should be some style recommendations/manual to make the YANG mechanisms used consistent between the different modules.

Disposition: The agenda was reviewed, discussed and approved.

The acting YANGsters Chair presented an overview of the Latest Ballots containing YANG modules. IEEE P802.1Qcx was presented during the TSN session on Tuesday September 17, 2019. Comment resolution should be finished soon. There is just one outstanding rogue comment.

Disposition: None.

The acting YANGsters Chair gave a Meta Data Update. YANGsters discussed how to apply the metadata using git to get this information into the YANG catalog. Currently there are no open issues regarding this topic.

Disposition: The proper metadata will be added once the document has been published. This will be done in coordination with Mark Ellison and Scott Mansfield.

The acting YANGsters Chair gave an introduction on IEEE EtherTypes. The meeting then discussed the PAR and CSD in preparation for their discussion within the IEEE 802.1 TSN TG later during the week.

The meeting discussed whether creating a standard with EtherTypes would be a secondary registry to the actual registry. There is the option of a tool that has been written by one of the YANGsters participants to automatically create this module from the information in the registry.

However, it does not fulfill all requirements from IETF:

  • The EtherTypes should have “friendly names”: this could be discussed to some degree.
  • The IETF would like a short list of their “favorites” and this needs to be discussed. It was suggested that it be made clear that the short list is from IETF and that IEEE just takes it over: this means the responsibility for the list itself would be on IETF.

IETF has already published their RFC; however, it still makes sense to continue the activity to reestablish that IEEE owns the list.

It was observed that:

  • There should be no duplicate registry within 802.1.
  • There should be no sub-setting.

Disposition: The TSN TG intends to draft a PAR and CSD this week for pre-circulation and forwarding to NesCom at the November 2019 plenary session. Generating the full EtherTypes list in a YANG module was preferred over a short list as the former ensures all the information is included. Implementers can then decide which one to use. It would also be best if the standard just consists of code to auto-generate the module along with an example snapshot (example YANG module). Alignment with RAC is required on the topic.

The acting YANGsters Chair gave a brief overview of YANGsters Next Meetings.

Disposition: The next YANGsters teleconference will be on Tuesday, September 24, 2019.

Any Other Business

The meeting discussed whether it makes sense to use of all the mechanisms that YANG provides and to create YANG modules that contain a lot of logic. YANGsters should provide guidance to editors on how much logic should be put into YANG modules provided by IEEE 802.1.

The upside of providing this kind of logic is that it is often easier to prevent the user from entering an incorrect configuration than it is to explain to an operator to not configure a device in a certain way.

Disposition: Further discussion needed. The topic will be discussed in more detail in one of the next meetings.

7:45 PM adjournment
