Disposition: The proposed responses are in http://www.ieee802.org/1/files/public/docs2018/802c-Marks-JTC1-SC6-pdis-0318-r1.docx. These responses were reviewed in the JTC1 SC Tuesday afternoon and further edited in http://www.ieee802.org/1/files/public/docs2018/802c-Marks-JTC1-SC6-pdis-0318-r2.docx.

 

Paul Bottorff, P802.1Qcy editor, provided an update on the Sponsor ballot for P802.1Qcy on http://www.ieee802.org/1/files/private/cy-drafts/d2/802-1qcy-d2-1.pdf.

  • Sponsor ballot was still open and needed four more responses for a valid ballot. It had no disapproves and one comment indicating that editorial coordination is met.
  • It was noted that the draft has a reference to the NVO3 draft on Split NVE Control Plane Requirements which is not an RFC yet.

Disposition:

  • The project edited a spontaneous liaison to share the draft with IETF NVO3: http://www.ieee802.org/1/files/public/docs2018/dcb-liaison-ietf-nvo3-vdp-1803-v1.pdf.
  • The project should wait until NVO3 has had a chance to comment on the draft before doing a recirculation.
  • The Chair was to prepare a motion for ballot resolution conference calls.
  • Paul Bottorff took an action item to submit comments about the dependency on the IETF draft progressing to RFC and on holding the draft for NVO3 comments.

 

Wednesday 07 March 2018

 

Joint meeting with TSN TG: 8:00 AM (call to order) to 9:00 AM

 

The DCB TG convened jointly with the TSN TG for presentations on the P802.1Qcz PAR.

 

Janos Farkas, TSN TG Chair, presented the IEEE-SA PatCom Patent Slides for Standards Development Meetings https://development.standards.ieee.org/myproject/Public/mytools/mob/slideset.pdf, and made the Call for Potentially Essential Patents. There were no responses to the calls prior to the end of the session.

 

Vahid Tabatabaee presented Congestion Isolation Proposal Analysis http://www.ieee802.org/1/files/public/docs2018/cz-tabatabaee-CIAnalysis-0318-v01.pdf.

Disposition: Related to proposed project; more discussion needed

 

Paul Congdon presented Lossless Bridges and CI

http://www.ieee802.org/1/files/public/docs2018/cz-congdon-lossless-arch-with-CI-0318-v1.pdf.

Disposition: Related to proposed project; more discussion needed

 

The joint meeting ended at 9:00 AM and the DCB TG meeting resumed separately.

 

9:00 AM to 12:00 PM

 

Patrica Thaler, DCB TG Chair, presented the IEEE-SA PatCom Patent Slides for Standards Development Meetings https://development.standards.ieee.org/myproject/Public/mytools/mob/slideset.pdf, and made the Call for Potentially Essential Patents. There were no responses to the calls prior to the end of the session.

 

Paul Congdon led the resolution of comments received on the draft PAR and CSD for proposed P802.1Qcz Congestion Isolation.

Disposition: New PAR development

 

 

Kevin Shen presented Simulation Analysis of Congestion Isolation (CI) http://www.ieee802.org/1/files/public/docs2018/cz-shen-congestion-isolation-simulation-0318-v01.pdf

  • Questions were asked about details of the simulations – details of traffic and the switch model. The simulation is based on an output queued switch. Concerns that that differs from the input queues or virtual input queues that many switches use to determine when to send PFC.

Disposition: Related to proposed project; more discussion needed

 

Paul Congdon presented Discussion of a Reference Diagram for CI

http://www.ieee802.org/1/files/public/docs2018/cz-congdon-refdiag-congdon-0318-v1.pdf.

Disposition: Related to proposed project; more discussion needed

 

4:00 PM to 6:00 PM

 

The DCB TG discussed what needs to be done to continue the Congestion Isolation (CI) work. The big question is around simulation model and results. A reference was made to a paper entitled Congestion Control for High-speed Extremely Shallow-Buffer Switches https://conferences.sigcomm.org/events/apnet2017/papers/bcc-bai.pdf that may use an acceptable model for a switch. This paper was also referenced in initial contributions on Congestion Isolation from 2017.

Key things needed to validate approach:

  • Correct Bridge Model: see paper referenced above.
  • Include latency of CIP message generation, propagation and processing. CIP messages are sent through the traditional bridge data path but at the highest priority.
  • Appropriate Traffic Pattern: RoCEv2 is a good use case. Consider using exactly what the DCQCN paper used. Look at the paper traffic models and use those because they are validated.
  • Correct Metric for Evaluation: Number of PFCs is important but may not be of customer interest. Flow completion time is critical. The tail latency or tail FCT is most important. Look at the public papers that are addressing 99% FCT (tail latency).  This should address “fairness” because the only real issue with fairness is a long tail latency.
  • Show all combinations of use cases for CI with and without PFC, with and without signaling.

 

The DCB TG reviewed Barak Gafni’s Congestion Isolation Backwards Implicit Notification http://www.ieee802.org/1/files/public/docs2018/cz-gafni-implicit-CIP-0318-v1.pdf.

  • There was some question about how much gain is achieved from signaling. Simulation from other contributions shows that a gain in flow completion times is achieved when PFC is used.

Disposition: Related to proposed project; more discussion needed

 

Thursday 08 March 2018

 

1:30 PM (call to order) to 6:00 PM

 

The DCB TG discussed the outcome of the 802.1 midweek plenary meeting regarding the motion on the draft P802.1Qcz PAR/CSD. While one of the Against voters on the P802.1Qcz PAR was willing to convert his vote, it was not recommended putting up a motion to reconsider. This was because there were so many Abstain votes that showing more understanding of the project was needed.

Disposition: It was decided to have a motion on Friday to further develop the draft P802.1Qcz PAR/CSD.

 

Yun Zhang presented An approach for auto-assignment of IP addresses for wired switches http://www.ieee802.org/1/files/public/docs2018/new-dcb-zhang-ip-assignment-0318-v01.pdf, a proposal for IP assignment via LLDP.

  • The DCB TG could not figure out how it works, but the motivation was clear.
  • It was suggested that the work would really be appropriate for the IETF since it is just defining an Organizationally Specific TLV.

Disposition: The IETF should be able to do this. There is no real project required in 802.1 for this activity.

4.2    Maintenance

Minutes of the discussions of these agenda items follow.

1. P802.1AR-Rev (Secure Device Identity)

Following discussion in the January 2018 interim meeting, a motion for P802.1AR-Rev draft 2.6 (http://www.ieee802.org/1/files/private/ar-rev-drafts/d2/802-1AR-rev-d2-6.pdf) to proceed to RevCom had been drafted and was considered and approved during the 802.1 midweek plenary meeting.

2. P802.1Xck (Port-Based Network Access Control: YANG Data Model)

Following discussion in the January 2018 interim meeting, a motion for P802.1Xck draft 2.0 (http://www.ieee802.org/1/files/private/xck-drafts/d2/802-1Xck-d2-0.pdf) to proceed to Sponsor Ballot had been drafted and was considered and approved during the 802.1 midweek plenary meeting.

3. P802.1AE-Rev MAC Security (roll-up and maintenance revision)

Mick Seaman, P802.1AE-Rev editor, presented the outcome of the WG recirculation ballot on http://www.ieee802.org/1/files/private/ae-rev-drafts/d1/802-1AE-rev-d1-1.pdf.

The Security TG reviewed the standard motion to proceed to Sponsor Ballot, and this was considered and approved during the 802.1 midweek plenary meeting.

4. P802E Privacy (Recommended Practice for Privacy Considerations for IEEE 802 Technologies)

Jerome Henry, P802E editor, was unable to attend this meeting but would attend the May 2018 IEEE 802.1 interim meeting and prepared an editor’s report: ieee802.org/1/files/private/802-e-drafts/d0/802E-d0-7-editors-report.pdf.

 

These documents are also available on Mentor in the Privecsg area.

 

Amelia Andersdotter presented Privacy Recommendations for 802 LMSC Section 8: Recommendations http://www.ieee802.org/1/files/public/docs2018/e-andersdotter-recommendations-0218-v00.pdf and Privacy Considerations: Threat mitigation strategies http://www.ieee802.org/1/files/public/docs2018/e-andersdotter-threat-mitigation-strategies-0218-v01.pdf.

  • The idea of phrasing the Recommendations as a list of points to be considered by the developers of an 802 technology/standard (essentially a self-evaluation with the points intended to stimulate that evaluation) was generally well received.
  • Discussion points included:
    • The approach was based on a similar approach and questions developed in the IETF. Does this raise a copyright issue? The detailed consideration and text were significantly different, so this issue should not arise.
    • The use of “service” to describe what was being provided by an 802 technology. This had been selected as a general term that was used across 802. The term could, however, invoke a range of interpretations depending on the reader of the recommended practice: for example, service provided by a network to the user of a personal device (with attendant billing, identification requirements, and SLA considerations) vs. the MAC Service (as defined in 802.1AC). Some expansion may be required to avoid different reader groups talking past each other when referring to the recommended practice.
    • The answers to a number of discussion points were answered elsewhere in the document. Much more extensive use of cross-references is required.
    • Some of the definitions were made shorter, to the point. This is in line with IEEE Style recommendations: the definitions should not themselves contain normative provisions or act as a substitute for the rest of the document. Definitions should also not cross-reference main text.
    • Some concern on making “shared service device” less prominent. Needs review.
    • Text should be added on including, in standards subject to this recommended practice, recommendations to users/implementers/network administrators making use of equipment conforming to the standard. Some equipment might be designed to be used in a wide variety of networks with different operation, manageability, and privacy requirements.
    • Recommendations need to take into account what is needed to operate a service and what is needed to manage or debug its operation in the face of potential misbehaving systems.
    • It would be good to test the Recommended Practice by drafting an appropriate clause for an 802 standard other than a wireless standard focused on providing access to personal devices. IEEE Std 802.1AS Timing and Synchronization for Time-Sensitive Applications in Bridged Local Area Networks might prove a suitably different example. This idea was raised during the closing 802.1 plenary meeting and met with some enthusiasm.
    • It is natural to consider an adversary positioned “on the medium” when considering wireless access from personal devices; however, an adversary might be (logically) positioned at other places in an 802 network, e.g. in an access point or edge bridge where some or all frame data is not protected by local encryption, and this should also be considered. One reason why a station’s MAC address is a privacy concern is its use as part of an IPv6 address and consequent visibility far away from the immediate 802 medium.
    • Recommendations should also apply where an 802 technology mandates or recommends a specific non-802 technology or technology choice, e.g. the use of an appropriate EAP method in conjunction with 802.1X/802.11.

5. P802.1X-Rev (Port-Based Network Access Control)

Mick Seaman, P802.1X-Rev editor, led the resolution of comments received from 802.3 and 802.11 on the draft PAR/CSD for P802.1X-Rev

  • Resolution: http://www.ieee802.org/1/files/public/docs2018/x-rev-seaman-PAR-CSD-comment-response-0318.txt.
  • A motion to forward the PAR was considered and approved during the 802.1 midweek plenary meeting. Subsequently an objection to the PAR was raised by an 802 EC member, on the grounds that the titles of referenced standards were not complete. The sense in which they were to be “complete” had not been previously specified, but the newly stated intention was that that meant including “IEEE Standards for Local and metropolitan area networks—“ in a title. There remains a question as to what the title of some of our standards actually is, particularly when the title that appears on the front page of the published document is not exactly what appeared on the relevant PAR. If the title is what appears on the front page of the standard excluding the usual banner header, then the title of IEEE Std 802 is “802 Standard for Local and Metropolitan Area Networks: Overview and Architecture”.
  • The proposed PAR was revised a number of times. http://www.ieee802.org/1/files/public/docs2018/x-rev-seaman-draft-par-0318-v05.pdf was considered and approved during the 802.1 midweek plenary meeting, and subsequently approved by the 802 EC.

6. Comments on 802.15 SECN (Security Next Generation) PAR

802.15 had pre-circulated the following draft PAR and CSD:

The Security TG reviewed and updated draft comments on Monday in http://www.ieee802.org/1/files/public/docs2018/security-comments-on-802-15-4y-secn-par-0318-v02.txt.

Brian Weis represented these comments during an 802.15 evening meeting called to review the PAR. Subsequent PAR revisions took these into account and appeared satisfactory.

7. A.O.B

No new items arising at this meeting.

8. Future meeting/teleconference planning

The usual motion for teleconferences was approved by the 802.1 closing plenary meeting. The Security TG will next meet at the May 2018 IEEE 802.1 interim meeting in Pittsburgh, PA, USA.

4.5    Time-Sensitive Networking

The Time-Sensitive Networking (TSN) Task Group Chair, János Farkas presided. Craig Gunther wrote the minutes.

 

At the beginning of the meetings on Monday (including the pre-meeting), Tuesday, Wednesday, Thursday and Friday, János Farkas presented the IEEE-SA PatCom Patent Slides for Standards Development Meetings https://development.standards.ieee.org/myproject/Public/mytools/mob/slideset.pdf, and made the Call for Potentially Essential Patents. There were no responses to the calls prior to the end of the week’s session. The agenda for each day was reviewed and approved.

 

In the remainder of this section, all tracks are TSN TG tracks, except when marked “JWG track”, in which case they are tracks used for Joint Working Group discussion not involving the rest of the TSN TG.

Scott Mansfield presented http://www.ieee802.org/1/files/public/docs2018/yangsters-smansfield-status-0318-v02.pdf starting by showing slides 1 through 4 (Participants, Patents, and Duty to Inform, Patent Related Links, Call for Potentially Essential Patents, and Other Guidelines for IEEE WG Meetings) and making the “Call for Potentially Essential Patents”. There were no responses to the call.

  • The 802.1 Chair reminded that the YANGsters group is tasked with coordinating the various 802 WGs on YANG issues and suggested that the agenda of slide 5 be reorganized to address non 802.1-specific items first; this reorganized agenda was approved.
  • As part of his presentation, Scott Mansfield also presented Network Management / YANG as a motivation for open source? (http://www.ieee802.org/1/files/public/docs2017/yang-parsons-open-source-motivation-1217.pdf), and http://www.ieee802.org/1/files/public/docs2018/yangsters-smansfield-pilot-query-0118-v01.docx
    • The 8021 Chair noted that:
      • IEEE 802 has a special arrangement with IEEE legal to allow the public postings of YANG modules with no password on GitHub to have the same licensing as applies to IEEE standards.
      • YANG modules corresponding to draft IEEE 802 standards in the pre-PAR phase could be posted in an “experimental” branch while those corresponding to draft or published IEEE 802 standards in the post-PAR phase could be posted in a “standard” branch on GitHub.
      • The normal IEEE 802 balloting process currently applies to YANG code on GitHub that is embedded into a draft IEEE 802 standard being developed, the editor adding comments, based on contributions to GitHub, to a ballot for processing as part of the regular process.
      • Content committed to GitHub branches is controlled by nominated participants to the regular IEEE 802 process to maintain order.
    • It was observed standards organizations other than IEEE 802 use their own processes to leverage YANG code contributions on GitHub.
    • The 802.1 Chair presented slide 9 and moderated a discussion of its content, clarifying that:
      • This content is specific to IEEE.
      • The IEEE Open Source pilot is investigating how to support open source activities within IEEE.
      • The IEEE Open Source activity, investigating Open Source and the use of source code in a standard, is unrelated to YANG though there might be a fit for YANG work as part of this activity.
      • There is a need to determine whether the benefits of using an Open Source Contribution License Agreement (OSCLA) are worth the costs in terms of complexity vs. using conventional Standards Contribution Copyright & Patent Policies (SCCPP), e.g.: merge vs. select one of several proposed YANG modules contributed to GitHub into a particular draft IEEE 802 standard; who oversees the design of a YANG module; how to align a draft IEEE 802 standard with GitHub development; how to maintain architectural integrity, etc.
      • There is a desire to guide the IEEE Open Source activity so that the resulting guidelines meet the needs of IEEE 802 YANG projects.
      • The OSCLAs considered in the IEEE Open Source activity are Apache (that has a royalty-free patent grant,) and BSD (that has no patent grant), and the YANGsters group can either decide not to use them or propose to use the familiar
      • Using an OSCLA would allow continuous update of YANG code on GitHub outside of the PAR process (e.g., for error correction).
      • IEEE 802 asked IEEE SASB ExCom to be grandfathered so that IEEE 802 may continue using the SCCPP if IEEE switches (as it plans) to using an OSCLA. IEEE SASB verbally accepted but is yet to provide written confirmation.
      • All comments received must be considered including those from the GitHub community, those from IEEE 802 voting members and those from Public Review.
      • All of IEEE 802 has a special dispensation for YANG code to be public when IEEE 802 draft standards are in the process of being developed.

Disposition: Discussion of the presented topics is to continue on YANGsters conference calls. The 802.1 Chair noted the preference for IEEE 802 grandfathering (i.e. 802 continuing to use the SCCPP) to be included as an option in the process that may result from relevant IEEE Open Source activity. He also suggested a chart be developed on how the GitHub community may interact with the IEEE 802 YANG standard community.

There was no other business to discuss and this YANGsters group meeting was adjourned at 9:30 PM.
