Potential Areas for IETF/IEEE802 Coordination 0. Revision History 0.0 Initial Revision - 9/4/2012 0.1 revised for the period between 9/5 and 10/29 0.2 revised according to input received on 01, still reflects the 9/5-10/29 time interval 0.3 revised after the 10/29/12 meeting 0.4 revised for the period between 10/29 and 12/12 0.5 revised after the 12/17/12 meeting 0.6 revised for the period between 12/17/12 and 2/5/13 0.7 revised for the period between 2/5/13 and 4/30/13 0.8 revised after the 5/2/13 meeting 0.9 revised for the period between 5/2/13 and 9/22/13 1. IETF TRILL Fine-grained labeling and IEEE 802.1 tags 1.1 Description - CLOSED 2. IETF BFD and IEEE 802.1AX 2.1 Description In the 7/25 f2f meeting Norman Finn noted that drafts have been written (but not adopted in IETF WGs) for using BFD to detect Link Aggregation failures. Norman suggested that BFD is at the wrong layer for this, and suggested the following ways to avoid layer violations: - Invent and use a Layer 3 equivalent of LACP that fits routing and BFD - Use Ether OAM; work with 802.1 to invent a way to avoid needless configuration. - Encapsulate BFD below LinkAgg thus giving the world two ways to do exactly the same job The routing AD (Adrian Farrel) clarified by email that the IETF has no intention of working on modifications to or a replacement for LACP. The only work being undertaken in this area is the ability to run BFD on LAG members and report failures of individual members as a degradation of the link constructed from the LAG. Liaison statements were changed between the IEEE 802.1 and IETF BFD WGs. The BFD WG sent to the 802.1 WG a liaison on 9/25 https://datatracker.ietf.org/liaison/1192/ setting out the progress and continuing the communication. The authors of the BFD for LAGs work have posted several updates, the latest at http://datatracker.ietf.org/doc/draft-mmm-bfd-on-lags/ Note that this work is still currently not official BFD working group work. However, a re-charter of the BFD working group was considered by the IESG, reviewed by the IETF community, and advertised on the New Work mailing list on 10/16. This change in the charter was approved by the IESG on 10/25 and includes the following text: > 5. Provide one or more mechanisms to run BFD over Link Aggregation > Group Interfaces. ...and... > The working group will maintain a relationship with the KARP and MPLS > working groups, and will communicate with the IEEE with respect to BFD > over LAGs. ...so it is expected that the BFD working group will adopt a draft to work on soon, and that they will be in touch with 802.1 again in due course. Status 12/17 (Adrian): we're progressing as expected and trying to communicate as much as possible with 802.1 as we go along. The BFD WG is not the fastest WG in the world, but I know the people involved are working on an interop event now, so there should be more to report in the new year. 5/22/13 - following mail exchange between Tony, Adrian and Dan information and request for comments from individuals about https://datatracker.ietf.org/doc/draft-ietf-bfd-on-lags/ was sent to the IEEE 802.1 WG reflector. Status 5/30/13 (Adrian, Dan): Revision -07 of draft-mmm-bfd-on-lags was posted on April 12th. It reflects the recent activity in interop testing and work with the IANA to make early allocation of codepoints. It was sent for comments to the IEEE 802.1 reflector on 4/29 Status 6/17/13 (Adrian): BFD on LAGs - The document has been adopted as a working group draft See it at http://datatracker.ietf.org/doc/draft-ietf-bfd-on-lags/. The problem statement document is in IETF last call until 19th June. This was announced on the appropriate IEEE exploders. Progress seems to be smooth and an RFC is likely to result relatively soon. The BFD working group is not meeting at IETF-87 in Berlin. 2.2 Relevant Documents https://datatracker.ietf.org/liaison/1192/ http://datatracker.ietf.org/doc/draft-mmm-bfd-on-lags/ https://datatracker.ietf.org/doc/draft-ietf-bfd-on-lags/ 2.3 Owners - Adrian Farrel, Norm Finn 2.4 Action Items - follow-up the evolution of the doc, as it is adopted as a WG item 3. IETF NVO3 and IEEE 802.1 DCB 3.1. Description IEEE 802.1Qbg VDP might be used as the basis for the communication that NVO may need between an end system and an external box (e.g. bridge or router) doing the NVO encapsulation. Coordination will help determine if VDP is a suitable candidate and possibly to make any amendment needed in VDP for NVO usage. Status 10/26 - not much progress. The NVO3 working group continues to work on architecture and requirements. It remains unclear whether a "new" encapsulation will be required. Many people consider that there are enough encapsulations in the world already. In the 10/29 meeting - concerns from the IEEE that some of the NVO requirement drafts say things about 802.1 and its capabilities that don't take all the capabilities into account. There are some above layer 2 reasons to do NVO, and we think the requirements doc would portray that more accurately going forward. Concerns with the way 802.1Q capabilities are being portrayed. Also there's an 802.1 protocol called DCB that may be useful and we want it to get fair consideration if it's a fit. Status 12/17 (Pat, Adrian): Things are going fine, but we'll need to keep this open as things go along. Status 4/30: draft-ietf-nvo3-overlay-problem-statement-02 is in WGLC, several comments from participants in both IEEE 802.1 and IETF 6/5/13: draft-ietf-nvo3-overlay-problem-statement-03.txt in IETF LC, announcement shared on list 3.2. Relevant Documents https://datatracker.ietf.org/liaison/1219/ http://datatracker.ietf.org/doc/draft-ietf-nvo3-overlay-problem-statement 3.3. Owners - Adrian Farrel, Pat Thaler 3.4. Action Items - Adrian to ensure that architecture and requirements are liaised to the appropriate parties of IEEE. Done. Liaison sent by NVO3 - follow-up and send documents for review as they are adopted as WG items, WGLC and IETF LC. 4. IETF awareness of IEEE 802.1Q-2011 4.1. Description - CLOSED 5. Effect of virtualization on IEEE 802 architecture 5.1. Description At the 7/25 f2f meeting Glenn Parsons presented a brief overview of the IEEE Registration Authority Committee (RAC) mission, highlighting the current RAC policy on virtualization and asking what virtualization policy would reduce the consumption of EUI-48 addresses. Norman Finn suggested this could be an area of collaboration between the IETF and the IEEE 802. At the 9/5 virtual meeting Glenn Parsons reported that the action item from the last meeting on updating the IETF on virtualization at the Vancouver IETF Meeting (July/August, 2012) was completed. Status 4/30 - Glenn Parsons submitted an I-D and gave presentations at IETF-86 in the Technical Plenary, OPS and INT area meetings. The IEEE RAC will finalize and approve the proposal by June. 9/9/13: draft-ieee-rac-oui-restructuring-01.txt submitted 5.2.

Description In the transition process between the IETF and the IEEE the following documents were taken over by IEEE 802.3: RFC 2108 - Ethernet Repeater Devices RFC 3621 - Power Ethernet MIB RFC 3635 - Ethernet-like Interface Types RFC 3637 - Ethernet WAN Interface Sublayer RFC 4836 - Ethernet Medium Attachment Units (MAUs) RFC 4837 - Ethernet Passive Optical Networks (EPON) RFC 4878 - Operations, Administration, and Maintenance (OAM) Functions on Ethernet-Like Interfaces RFC 5066 - Ethernet in the First Mile Copper (EFMCu) Interfaces MIB The IF-CAP-STACK-MIB in RFC 5066 is generic and the IETF proposed to continue to be maintained by the IETF in a separate new document The IEEE 802.3 proposed to create an RFC that documents the issues related to the transition of the Ethernet MIB work to IEEE 802.3 similar to RFC 4663 which documents the transition of the Bridge MIB work to IEEE 802.1 - The OPSAWG was rechartered in October 2012 to include the two relevant documents - Status 4/30/13: draft-ietf-opsawg-rfc5066bis received a number of substantial comments in the OPSAWG review which resulted in the need for substantial edits, revised version is still in progress. The second I-D was not submitted yet. The IEEE 802.3.1 completes Recirculation Sponsor Ballot on 4/30. Dan submitted an Approve ballot, the document is expected to be released in June, probably with reference to the Internet-Draft. - Status 5/6/13: revised I-D draft-ietf-opsawg-rfc5066bis-02 was submitted, second Recirculation Ballot in IEEE 802.3.1 completed - Status 6/19/13: IEEE standard approved - Status 6/25/13: revised I-D draft-ietf-opsawg-rfc5066bis-03.txt submitted - Status 8/13/13: IEEE standard published as IEEE 802.3.1-2013 7.2.

IETF 6LOWPAN and IEEE 802.15 8.1. Description - CLOSED 9. IETF PAWS WG and 802.11, 802.19, 802.22 9.1 Description - At the 9/5 virtual meeting Bruce Kraemer volunteered that one of the IETF PAWS WG Chairs (Gabor Bajko) is active in 802.11. Dan Romascanu took an action item to clarify with Gabor Bajko and Pete Resnick if there are any action items that need to be taken immediately regarding coordination. Gabors answer was that the coordination between IETF PAWS and IEEE 802.11af, 802.19 and 802.22 was so far handled by him; Gabor presented periodic updates of PAWS to these IEEE 802 groups, and took their input back to PAWS. So far this type of coordination did the job, although in the future some of this interaction may need to be handled via the official channels. - At the 10/29 meeting we confirmed the decision to take out IEEE 802.15 and IEEE 802.16 from the list. Coordination continues by now via participation of Gabor Bajko in both SDOs. Need confirmation this is OK with IEEE 802 - Status 4/30/13: draft-ietf-paws-problem-stmt-usecases-rqmts-15 was last-called and approved by the IESG, draft-ietf-paws-protocol is still in pre-WGLC state - Status 5/2/13: reasonable progress with draft-ietf-paws-protocol, no worries about progress - 6/20/13: Last Call issued on http://tools.ietf.org/html/draft-ietf-paws-protocol-06, sent to the coordination list 9.2 Relevant Documents - http://datatracker.ietf.org/wg/paws/charter/ - https://datatracker.ietf.org/doc/draft-ietf-paws-problem-stmt-usecases-rqmts/ - https://datatracker.ietf.org/doc/draft-ietf-paws-protocol/ - http://www.ietf.org/mail-archive/web/paws/current/msg01535.html 9.3 Owners: Bruce Kraemer, Gabor Bajko 9.4 Action Items - clarify whether IEEE 802.11af, 802.19 and 802.22 are all the relevant groups within IEEE 802 that need coordination with PAWS, modify item title accordingly - Done - Bruce to confirm the list and clarify at the IEEE plenary whether the current level of coordination is sufficient - Done - PAWS WG chairs to notify the IEEE 802 WGs when documents reach Last Call 10. IETF IPPM and LMAP, and IEEE 802.16 Metrology Study Group 10.1 Description - IEEE 802.16 Metrology Study Group => IEEE P802.16.3 ("Mobile Broadband Network Performance Measurements") - Coordinate future work in the IEEE 802.16 with existing work in the IETF - Status 4/30/13: LMAP BOF held at IETF-86, IEEE 802.16.3 met at the IEEE 802 Plenary, sent liaison statement requesting LMAP perspective of IEEE Project P802.16.3 Architecture and Privacy - https://datatracker.ietf.org/liaison/1244/ - Status 5/2/13: LMAP is still in pre-charter mode, official communication will be possible only after chartering - Status 9/13: the LMAP WG was chartered and hold its first meeting at IETF-87. Status of the IEEE 802.16 Metrology activity unclear. Do we need to keep this AI open? 10.2 Relevant Documents http://datatracker.ietf.org/wg/ippm/ http://www.ieee802.org/16/mbnpm/ https://datatracker.ietf.org/liaison/1195/ http://www.ietf.org/mail-archive/web/lmap/current/msg00132.html http://www.ietf.org/mail-archive/web/lmap/current/msg00200.html http://datatracker.ietf.org/wg/lmap/charter/ 10.3 Owners - Roger Marks 10.4 Action Items - IEEE 802.16 to send a statement to IETF IPPM WG informing them of the status of the activities of 802.16, and possibly asking for input - Done (sent to IPPM with CC to LMAP list) - Done - email response sent by IPPM chairs and AD to IEEE 802.16 chair on 11/28 - Done - Report on P802.16.3 sent to LMAP list on 2012-11-19 <http://www.ietf.org/mail-archive/web/lmap/current/msg00132.html> - Report on P802.16.3 sent to LMAP list on 2013-01-24 <http://www.ietf.org/mail-archive/web/lmap/current/msg00200.html>. 11. IETF Mobile IP and EC OmniRAN Study Group 11.1. Description At the 7/25 f2f meeting Roger Marks presented a proposal for a new IEEE 802 WG to specify access network abstraction layer above IEEE 802 access technologies, noting that the work is related to some IETF WGs (e.g. DMM, MIF, NETEXT), and made the following recommendations: - IEEE 802 OmniRAN can close the gap and tie 802 devices into a family of standards within a heterogeneous IP network supporting evolving IETF standards - IEEE 802 and IETF should: * leverage each other's expertise * plan communications * identify commonalities * link solutions * organize a team to coordinate milestones and progress At the 9/5 virtual meeting Roger Marks indicated he would be the owner of this item. An action item was identified: Roger Marks to form a team to discuss coordination with possible input from Brian Haberman and Charlie Perkins. Roger reported in the 10/29 meeting that discussions are expected to be hold at the plenary meeting and he expects to have information to report after the plenary Roger reported in a mail sent on 11/26 that the IEEE 802 Executive Committee (EC) initiated the EC OmniRAN Study Group. It is chartered through the March 802 Plenary, with an expectation of extension through July. Max Riegel is the chair. Max Riegel sent a mail to the IESG on 12/11 including information on the Study Group 12/17 Status (Roger): Next Study Group meeting in January, will discuss requesting time in the INT Area meeting for a presentation and discussion Status 4/30/13: OmniRAN presentation was given at the 3/6/13 face2face meeting followed by Q&A and discussions Status 5/2: There is concern in 802 about what part of the problem belongs in 802 and if so in an existing group like .1 or .21, or a new group. Not expecting the group to settle on this until we're approaching the November meeting. Still working on the problem statement. 5/13: OmniRAN report presented at IEEE interim meeting presentation pointer sent to the list 11.2.

Owners - Max Riegel 11.4. Action Items - Discuss communication and coordination level in the 12/17 meeting - Done - IEEE will communicate after the January Interim whether to request presentation and discussion time in the INT Area meeting in Orlando. Done - planning for a 30 min presentation on the OmniRAN SG at the face-to-face leadership meeting by Max Riegel - Done - IEEE 802 will update about outcome of the SG work - probably after the November Plenary meeting 12. IETF HOKEY and IEEE 802.21 12.1. Description CLOSED 13. IETF MIF and IEEE 802.21 13.1. Description - IETF MIF should not re-do the work that 802.21 has already done * 802.21 defines a Media Independent Services SAP (API) that provides most of the functionalities that MIF is looking for * 802.21 also defines low level Media Specific SAPs for the underlying access technologies - IETF MIF should identify requirements and make references to 802.21 SAPs where appropriate * If non-existing functionalities are identified both MIF and 802.21 should work together At the 5/9 virtual meeting Dan Romascanu took the action item to ask Subir Das to clarify what is required. Subir answered that the relevant discussions will take place at the November IEEE 802 plenary At the 10/29 virtual meeting Subir reported about the discussion with MIF in Vancouver, and there presentations in .21. There's a joint draft from both groups that will be presented at Atlanta IETF. Hoping for more discussion. Ralph confirmed that the draft's been posted, did not review it yet. 12/17 Status (Ralph): There was a discussion at the MIF WG regarding a draft describing the relationship of the work in MIF and in 802.21. Agree that there is some overlap, but not clear to what degree yet. A couple of different potential architectures proposed and discussed. Status 4/30: An 802.21 overview I-D was submitted draft-zuniga-mif-802-21-overview. The MIF architecture team has met twice since Orlando. Discussion at this point is at a high level, and doesn't really touch directly on 802.21. Juan-Carlos Zuniga volunteered to work on this team. It's unlikely that the team is going to reach the point of directly discussing 802.21-related work between now and Berlin; at this point the strategy is to document use cases and identify changes to IP-layer protocols and protocol use patterns as they relate to various Multiple Provisioning Domain (MPD) scenarios the team has identified. The team does intend to address the behavior of the host, and at that point we will probably start thinking about how what we are talking about relates to 802.21, but the current strategy is to address that aspect of the MPD work only after having thoroughly explored use cases and trying to come up with a strategy for addressing gaps in existing IP protocols. Status 2/5/13 (Ted): The MIF WG currently has an action to develop an architecture doc and that's the main thing they're dong right now. The architecture doc is focusing on layer 3 and above. The doc doesn't talk much about layer 2. Right now I don't think it will have a direct impact on anything in 802.21, but it's early days yet. Juan-Carlos did volunteer to participate and keep us apprised of any conflicts. Should have more output on the process either by the next coordination call or the July IETF meeting. Status 9/19/13 (Ted): The work was presented in Berlin and was well received. Work continues. There's nothing particularly new to report on that front, although Juan Carlos seems to be doing a good job of keeping the team informed of related work in the IEEE. We're expecting a fairly mature version of the document to be presented to the working group for adoption prior to Vancouver. 13.2.

IETF IPFIX Information Elements for Data Link monitoring The IPFIX WG specifies a couple of data link Information Elements, to be added to http://www.iana.org/assignments/ipfix/ipfix.xml. Feedback from the IEEE on the Information Element specifications would be appreciated. Information Elements for Data Link Layer Traffic Measurement draft-ietf-ipfix-data-link-layer-monitoring-00 Abstract This document describes Information Elements related to data link layer. They are used by the IP Flow Information Export (IPFIX) protocol for encoding measured data link layer traffic information. Status 12/17 (Benoit): I-D was sent via liaison for review to IEEE 802.1, missed deadline for a formal answer (during IEEE 802 Plenary week), was later forwarded to the IEEE 802.1 reflector for comments from individuals, but did not get any feedback Status 4/30/13: WGLC was announced on the coordination list. Comments made by Pat on draft-02 were discussed; they need to be addressed by the editors in draft-03 Status 2/5/13 (Benoit): Should be ready to progress to IETF LC soon. Waiting on a revision from the author first. 14.2. Relevant Documents - http://datatracker.ietf.org/doc/draft-ietf-ipfix-data-link-layer-monitoring/ 14.3. Owners - Benoit Claise and the IPFIX chairs (Juergen Quittek <Quittek@neclab.eu>, Nevil Brownlee <n.brownlee@auckland.ac.nz>) 14.4. Action Items - IETF needs to receive feedback from the IEEE - Done - Action (Benoit): Proceed to IESG review, send again to IEEE 802.1 for review during IETF Last Call - Feedback (by Pat Thaler) received on the IPFIX list, authors will address it on the list and on revised I-D 15. IETF RADIUS attributes for IEEE 802 networks The RADEXT WG specifies RADIUS attributes related to IEEE 802 network. Feedback from the IEEE on the attributes specifications would be appreciated. RADIUS Attributes for IEEE 802 Networks draft-ietf-radext-ieee802ext-02.txt Abstract RFC 3580 provides guidelines for the use of the Remote Authentication Dialin User Service (RADIUS) within IEEE 802 local area networks (LANs). This document proposes additional attributes for use within IEEE 802 networks, as well as clarifications on the usage of the EAP- Key-Name attribute, updating RFC 4072. The attributes defined in this document are usable both within RADIUS and Diameter. Status 12/17: comments received from 802.11, but not from 802.1. I-D forwarded for comments to participants in the Security TF Status 1/31: message from Mick Seaman - no comments from the Security TF Status 4/30/13: second WGLC was distributed, comments received from Max Riegel need to be addressed Status 5/2/13 (Benoit): One new revision of this was posted today. Not sure if this is final, a third WGLC until May 9th. Status 7/13: draft-ietf-radext-ieee802ext-08.txt submitted and discussed at IETF-87 with remote participation from Mick Seaman 15.2. Relevant Documents: http://datatracker.ietf.org/doc/draft-ietf-radext-ieee802ext/ 15.3. Owners Bernard Adoba, the RADEXT chairs (Jouni Korhonen <jouni.korhonen@nsn.com> and Mauricio Sanchez <mauricio.sanchez@hp.com>), and Benoit Claise 15.4. Action Items - address issues raised by Max Riegel in draft-03 - send again document for comments when it reaches IETF Last Call 16. IEEE802.1Q SRP (and Gen2 updates) and RSVP/SIP 16.1. Description IEEE 802.1Q currently includes a procedure for reserving bandwidth for particular streams and learning the worst case delays for those streams. Streams are identified using a stream ID that is the concatenation of the source MAC address and an arbitrary 16-bit number (for IP streams, it was expected to be the port #, but the only requirement is that it be unique for a particular source MAC address). The reservation is made using the 802.1Q MRP scheme, where the registration parameters are the StreamID, a destination MAC, a QoS class, a bandwidth requirement, and a stream ranking. Currently, the destination MAC address *must* be a group address, even if there is only a single listener since so many of the use cases need multicast, and handling both unicast and multicast was originally viewed as needless complication. The QoS class is called an "SR Class" and currently corresponds to expected delay requirements, where class A is for highly interactive applications such as live musical performance, while class B is for less stringent uses. Bandwidth is measured as worst-case bytes per second as measured over a class-specific interval (125us for class A, 250us for class B). Rank currently only has two values, "emergency" and "normal". The intention always was to allow RSVP and/or SIP to use SRP procedures to gain true L2 guarantees on bandwidth and latency, but not much has been done up to this point. There is an industry-specific effort underway by the AVnu Alliance (www.avnu.org) to specify a way to use SIP/SDP as a way for applications to access SRP services across multiple subnets. SRP is under revision right now, with various improvements in the queue: 1) Two-way and unicast reservations (for VOIP-type applications) 2) Multiple path establishment using IS-IS topology discovery. 3) Reduced "chattiness" due to the current MRP procedures. 4) Expanded QoS classes to support new scheduled (802.1Qbv) and preempting (802.1Qbu) traffic. 5) (others) 12/20: Response from RAI AD Gonzalo Camarillo - with respect to point 16, I assume your intention is to work on extending SIP and SDP and not so much on extending RSVP, is that correct? If so, a good starting point would be to get your technical people to discuss those issues on the DISPACTH mailing list: https://www.ietf.org/mailman/listinfo/dispatch The DISPATCH community may direct you to other working groups (e.g., SIPCORE or MMUSIC) if needed. - 2/5/13: missing status from Michael - 5/21/13: The PAR and 5Criteria for P802.1Qcc Stream Reservation Protocol (SRP) Enhancements and Performance Improvements distributed to the mail list - Status 6/17 (Michael): The TSN (time-sensitive networking)) task group has agreed that the cooperation with the IETF is vital, but we haven't got ourselves properly organized to make real progress. It is on the agenda for the July meetings in Geneva, however. Since there is no real overlap in working group membership between TSN and DISPATCH or TSVWG (and everyone has day jobs), it's hard to recruit people to do this nonetheless, the chair (me) will find someone(s) willing to start the coordination by the end of the summer. - 7/13: P802.1Qcc approved QUESTION: should we keep this item open? 16.2.

IEEE 802.1AS/1588 and NTP 17.1 Description IEEE 1588 and its primary L2-only profile, IEEE 802.1AS, define protocols and procedures for very precise and fast-responding synchronization. These procedures require some hardware-level time stamping services, and, in some cases, on-the-fly modification of packets as they are transmitted. 1588 is heavily used within the telecom and test/measurement community, and has been proposed for various smart grid applications as well. The L2-only 802.1AS is used in professional A/V networks, and is also in other environments where multiple L2 technologies are needed (the other 1588 profiles are Ethernet-only, even though they use IPv4 or IPv6 packet formats). The time format chosen by 1588 is a 64-bit seconds/nanoseconds composite instead of a seconds/fractions of a second composite as used by NTP. (Hey, don't blame me! I wanted the NTP format, myself.) Right now there are no specified procedures for NTP to use 1588/802.1AS when available, nor is there a router spec to define how 1588 can be used in the wider internet. There *are* a few papers that show that a "universal" time router/bridge could be built, and that if it were properly specified, the performance would be equivalent to any particularly 1588 profile. IEEE 1588 is about to be opened for revision, and the IEEE 802.1AS revision has already started as project 802.1ASbt. Status (4/30/13 - Brian): The action item to form a small design team is on hold from the IETF perspective. After some discussion, it was decided to hold off on the formation of any design team until the IEEE 1588 PAR is approved and the 1558/TICTOC liaison is in place. Once those actions happen, we can revisit the topic.

Description RTP is viewed as the primary packet format for IP-based audio and video streams. The existing protocol uses various methods for labeling the time-significance of a particular chunk of data, and then uses yet another protocol (RTCP) to do the "cross timestamp" to associate the somewhat abstract timestamp used in the RTP packets to another time source that has more relevance to the application. IEEE 1722 is a non-routable simple streaming format similar to RTP and the IEC 61883 formats used by Firewire: IEEE 1394). Although 1722 was originally only being used in the pro A/V community, it's also being used in automotive and industrial control networks. Recent work in the IETF AVT-core group is building on new RTP extensions so that a precise timestamp based on 1588 or NTP can be directly used without the RTCP cross-timestamp. This simplification work opens up the possibility of using RTP as an IP carrier of IEEE 1722 streams in mixed IP/1722 environments. 12/20: Response from RAI AD: you probably want to start by discussing the issues on the AVT mailing list (AVTCORE working group). The actual work to be done may end up in a different working group (e.g., AVTEXT), but starting discussions on the AVT list is a good starting point. https://www.ietf.org/mailman/listinfo/avt If in addition to engaging with the right technical people at the IETF (to be found in the mailing lists above) you would like to get some type of support from us (i.e., the area directors), just let us know and we will be more than happy to help. 2/5/13: missing status from Michael 18.2.

Description - proposal made by Tissa Senevirathne and a group of TRILL contributors at the IEEE 802.1 meetings in July and September to reuse the IEEE 802.1ag frame format for TRILL OAM. Needs coordination and architectural consistency with the IEEE 802.1 architecture and OAM practice. - discussion at the 10/29 meeting: The requirements doc is going through WGLC so will come to IESG fairly soon. The framework doc being considered as a WG doc, so it has some time before it will be published by the WG. - Status 12/17 (Ralph): Had a conversation with the TRILL WG, they're going to progress the work for OAM for TRILL by progressing a requirements doc then a framework doc. If at that point they decided to go with an 802.1 base, they will go back to 802.1 and make sure that it doesn't infringe on the 802.1 OAM. But have to get the requirements and framework done first. - Status 4/20/13: https://datatracker.ietf.org/doc/draft-ietf-trill-oam-req/ was published as RFC 6905, draft-ietf-trill-oam-framework is discussed by the WG (pre-LC), draft-tissa-trill-oam-fm was not yet adopted as WG item - Status 2/5/13 (Donald): Framework draft had a lot of comments, expecting to be WGLC soon. Fault management doc needs to be reviewed, and then there will be an effort to move that to WG doc. The performance management doc is not as far along. - 8/20/13: The TRILL WG re-chartered, new charter includes OAM. Rechartering was communicated on the mail list. 19.2.

Description: BOF activity in the IETF which may lead to the formation of a WG which would focus one enabling IPv6 over the TSCH mode of the IEEE802.15.4e standard. If formed, the working group will define an open standard-based architecture that covers the formation and the operation of a wireless mesh based on the TSCH technology, and the aggregation of multiple meshes over a high speed backbone, including security, link management for the IPv6 network layer consumption, peer management and routing. The group will document best practices, and standardize the missing components to achieve industrial-grade criteria for jitter, latency, scalability and reliability. In particular the group will define how packets that belong to a deterministic IPv6 flow are marked and routed or forwarded over the mesh within jitter and latency budgets. When possible, the group will reuse existing protocols such as IPv6 ND, RPL and 6LoWPAN with the minimum adaptation required to meet criteria for reliability and determinism within the mesh, and scalability over the backbone. The WG will focus on three scheduling models: - a centralized route computation that builds and maintains the communication schedule, and distributes it to the nodes. This schedule includes forwarding information associated to time slots; RPL operations only apply to emergency repair actions when the reference topology becomes unusable. - a distributed resource reservation and signaling protocol that establishes tracks between source and destination nodes along multi-hop routes identified by RPL. - a best effort resource allocation that is used to transport data frames on a per hop basis in the absence of a reservation protocol. In IEEE 802.15: (Bob): Go to the 802.15 website and look for L2R under public docs. The group formed in March with a goal to spend 6 months to end up at a project point.
