About the BoFs at IETF 121

Media current

In a previous blog post on the Standards Observatory, we discussed what Birds of a Feather (BoF) sessions are and why they are important to the IETF. There are five BoFs scheduled at the upcoming IETF 121 meeting. This post looks at each of the BoFs with a preview of what to expect in Dublin.

What Happened at the previous, IETF 120 BoFs?

There were five BoFs at the Vancouver IETF 120.

alldispatch

While not really a BoF, alldispatch had its second session in Vancouver. The second session was much more successful than the first and was notable for the number of proposals for changes in the way the IETF (and, IANA) operate. The IESG has elected to continue with the alldispatch "experiment" in Dublin - see below

The Standard Communication with Network Elements BoF became a full working group after the Vancouver meeting. You can see the Datatracker page for the new working group here.

diem

The digital emblems BoF met in Vancouver and is meeting again in Dublin. You can see more about the second digital emblems BoF [below](#diem "The DIEM BoF at Dublin IETF 121").

Getting Ready for Energy-Efficient Networking was a BoF in Vancouver and became a full working group after IETF 120. You can see the Datatracker for the new working group here.

nasr

The network attestation for secure routing BoF took place in Vancouver, but a scheduled interim meeting (to be held after Vancouver) was cancelled. Instead, the group interested in nasr is having a side meeting on Monday, November 4 from 7:00pm to 8:00pm in room WMR4 in Dublin.

BoFs at the Dublin (IETF 121) IETF meeting

 The current agenda for the IETF 120 meeting to be held in Dublin in November 2024 includes five agenda items listed as BoFs:

  1. hpwan - High Performance Wide Area Network - Monday, November 4 from 1:00pm to 3:00pm
  2. alldispatch - not really a BoF - Monday, November 4 from 3:30pm - 5:00pm
  3. diem - Digital Emblems - Tuesday, November 5 from 9:30am - 11:30am
  4. rpp - RESTful Provisioning Protocol - Wednesday, November 6 from 9:30am - 11:30am
  5. deepspace - Deepspace - Thursday, November 7 from 1:00pm - 3:00pm

hpwan

The High Performance Wide Area Networking BoF emerged from a side meeting held at the Vancouver IETF 120 meeting. The meeting at IETF 121 is a non-Working Group forming meeting with the intention to bring together interested parties who would like to work on networks that are engineered for high-speed, low-latency, and ultra-high-volume applications in environments such as research, academia, and large-scale data processing.

According to the BoF proposal: "The thrust of the BoF will be to bring together interested parties, including those operating R&E infrastructures, to discuss existing practices, what works, what does not work. The output of the BoF would be to document requirements for such infrastructures, and then identify potential avenues for IETF work to improve transport protocols to make large-scale data transfers more effective over wide-area, high RTT, potentially lossy paths, where the physical (inter-continental) infrastructure may be shared between multiple research and science communities."

hpwan already has four Internet Drafts under discussion on its mailing list:

draft-zhao-hpwan-scenarios-deployment-00 - Scenarios and Deployment Considerations for High Performance Wide Area Network

draft-yy-hpwan-transport-gap-analysis-00 - Gap analysis of transport protocols of high performance wide area network

draft-xiong-hpwan-uc-req-problem-00 - Use Cases, Requirements and Problems for High Performance Wide Area Network

draft-kcrh-hpwan-state-of-art-00 - Current State of the Art for High Performance Wide Area Networks

alldispatch

alldispatch is a BoF in the general area which does not adopt drafts, but instead provides a direction for the authors of a draft to ensure that the draft gets further consideration at the IETF. The IESG describes alldispatch as an experiment, but it difficult to imagine how the IESG will retreat from having alldispatch sessions. It's also difficult to understand why these sessions are still characterized as a BoF and not simply part of the regular work in the General Area of the IETF.  

The first such BoF, held at IETF 119. was not a roaring success because authors (and other participants) tried to discuss the substance of their proposals rather than where in the IETF they should go. The second all dispatch at IETF 120 in Vancouver was notable for the number of proposals that were about IETF operations and procedures rather than protocol development. The alldispatch session was meant to be IETF-wide and not specific to any particular area in the IETF. The six results that are possible after a discussion in all dispatch are:

1. Direct the work to an existing WG 

2. Propose a new focused WG 

3. Recommendation to hold a full BOF 

4. Publish as AD-sponsored (assuming AD is willing) 

5. Additional discussion or community development required (e.g., with a new non-WG mailing list)

6. Work is not appropriate for IETF

The agenda for alldispatch at IETF 121 is available here. Here are the links to the twelve proposals to be discussed:

1. Proposals on Standards Processes

2. Proposal on Roles for the IETF Chair

3. Proposal on High Assurance Distributed Identifiers using the DNS

4. ALFA 2.0 - the Abbreviated Language for Authorization

5. Proposal on Identifying and Authenticating Home Servers

6. Proposals to update IDMEFv1

7. Proposals on the Security Event Tooken (SET)

8. A File Format to Aid in Consumer Privacy Enforcement, Research, and Tools

9. EMAIL: Why DKIM Needs Replacing

diem

The Digital Emblems BoF in Vancouver was very well attended and the mailing list has been very active. The goal of the BoF session in Dublin is to decide on a way forward for the work. On the mailing list there has been discussion of the definition of a digital emblem, why the physical use case for Digital Emblems might be important and a proposed charter.

There are three Internet Drafts on the topic:

draft-bwbh-digital-emblem-model-00 - Conceptual Model for Digitized Emblems

draft-linker-digital-emblem-02 - Problem Statement for a Digital Emblem

draft-haberman-digital-emblem-ps-02 - Problem Statement for Digitized Emblems

Note that all three of these drafts were not updated after the Vancouver meeting. At the end of September a complete redraft of the proposed charter was posted. You can compare the new draft to the original one which is still available here. The proposed, new charter has received substantial discussion on the mailing list.

rpp

The RESTful Provisioning Protocol BoF is a very tightly focused working group forming activity. It's background is as a successor/evolution to the very successful Extensible Provisioning Protocol this is used as a communication protocol between domain name registries and registrars. It's mostly about evolving the functions of EPP. Though EPP RFC5730 is still serving the domain name industry well, there is a desire to have more modern tools. RPP would be a provisioning protocol that uses the REST architectural style and the JSON data-interchange format. 

Total compatibility between EPP and the proposed RPP is not necessarily a goal of the work in the IETF. EPP, and its extensions, already have a working group in the IETF: REGEXT. A proposed charter has a requirements document created first, and only after that work on protocol specifications.

There is a single document related to rpp in the Datatracker:

draft-wullink-rpp-json-00  

EPP XML to RPP JSON conversion rules

deepspace

Deep space communications involve long delays (e.g., Earth to Mars is 4-20 minutes) and intermittent communications, because of orbital dynamics. The combination of long delays and intermittent communications makes the round-trip time very large and very variable. Space agencies and private sector are planning to deploy IP networks on celestial bodies, such as Moon or Mars, ground, orbits and vicinity. By having the deep space links also IP, it makes a complete end to end IP network. However, given the delays and disruptions, the upper layers such as transport and application protocols have to be profiled to support this environment. While deep space is defined by ITU as 2M km away from Earth, therefore excluding Moon, this work does include Moon deployment.

The IETF previously had a Delay Tolerant Networking working group and there was some call to merge this work with the work of DTN. The DTN is focused on implementations using the Bundle Protocol and proponents of the BoF on DEEPSPACE have suggested that a separate working group be formed. It a working group forming BoF.

There are already five Internet Drafts related to deepspace:

draft-many-deepspace-ip-architecture-00 - The IP Protocol Stack in Deep Space: Architecture

draft-nandakumar-deepspace-moq-00 - SPACE - Scalable Pubsub, Asymmetric and CachEd transport for Deep Space communications

draft-many-deepspace-quic-profile-00 - QUIC Profile for Deep Space

draft-many-deepspace-ip-assessment-02 - Revisiting the Use of the IP Protocol Stack in Deep Space: Assessment and Possible Solutions

draft-burleigh-deepspace-ip-assessment-00 - Revisiting the Use of the IP Protocol Stack in Deep Space
