1. Information-Centric Networking RG (ICNRG) Review

  Dave Oran updated the IAB on the Information-Centric Networking
  Research Group (ICNRG).

  ICNRG was chartered in early 2012 with Börje Ohlman, Dirk Kutscher,
  and Dave Oran as co-chairs. Early work focused on use cases, research
  challenges, and discussion of a variety of protocol architectures:

  • NetInf (SAIL Project in Europe)
  • PSIRP (Pursuit project in Europe)
  • CCN (NSF Future Internet Architectures project in US)

  Early technical topics included routing scalability, name-based
  routing versus name resolution, and performance versus complex
  features tradeoffs.

  CCN-based protocols gained most traction in the research community
  until a split between UCLA and PARC over IPR issues with CCN,
  resulting in two parallel efforts: NDN and CCNx. INCRG coordinated
  work on things that applied to both protocols, like congestion
  control, name-based routing versus named resolution, and various
  security issues.

  ICN got a dedicated SIGCOMM-sponsored conference in 2013, and there
  is lots of activity at other major conferences like INFOCOM, NSDO,
  and ICNP. ICN conference support ended in 2023, but is now a track at
  ICNP. A few long-running projects continue, and ICNRG participation
  is stable after an earlier drop during the pandemic. There has been a
  shift in focus away from content retrieval; the new focus is on
  distributed computing for AI and other large-scale distributed
  applications.

  ICN ideas have propagated into other work:

  • CBOR & COSE
    - object-based security
    - IoT applications
  • MOQ
    - Media object packaging
    - Caching hierarchies
    - Multi-destination delivery
  • Internet Decentralization
    - Security & Naming for limited domains

  Current work for ICNRG covers both CCNx and NDN protocol families:

  • Reflexive Forwarding - Accommodate multi-way handshakes for
    - Remote method invocation
    - “Phone home” sensor applications
    - Restful Web transactions
  • Object Manifests with FLIC
    - Handle large objects
    - Solve some thorny naming problems
    - Eliminate need for per-packet signatures
  • ICN approaches for Metaverse Applications


  With Dirk Kutscher as the new IRTF Chair, ICNRG is currently looking
  for a new co-chair. Participation in meetings is declining slowly,
  but still above critical mass. There is still interesting research
  being down on distributed computing scalability, security in limited
  domains, name privacy, and DDOS mitigation.


2. Meeting / work approach

  The IAB reviewed its current approach to work and meetings.

  Tommy Pauly noted that good examples of delegated work include:

  • Liaison coordination
  • IAB-ISOC group, participation in IGF and WSIS+20
  • Appeals processing
  • IP-Geo workshop planning
  • Technical programs
  • ... and of course IESG liaison, NomCom liaison, etc. Thank you!

  IAB members are across many timezones. The times when everyone is
  required to be present need to be well understood and worth people's
  time. Some people engage more over email and Slack, while others
  mainly engage when they are in a call or meeting.

  Requiring all IAB members to be in every conversation isn't efficient
  (e.g. group wordsmithing). However, having people missing from topics
  where they need to give input isn't effective either.

  Currently, there are monthly(ish) formal board meetings and weekly
  informal meetings scheduled for the rest of this IAB term. Programs,
  administrative groups, workshop groups, and liaison coordinators meet
  on their own cadence.

  Warren Kumari said it would be helpful if there was more information
  sharing back from the smaller group discussions. Matthew Bocci
  agreed, and asked to see more detail on the agendas.

  Tommy Pauly said that the agendas for informal meetings should go out
  on the Friday before the meetings.

  Cullen Jennings said that we need detailed agendas and status reports
  on work in progress, not just once work has been completed. He also
  said that there needs to be more clarity on what work is being
  delegated.

  Mark Nottingham said that meeting agendas should have more detail and
  be published farther in advance. It would also be helpful to have an
  agreed-upon source of truth for information (GitHub, wiki,
  Datatracker).

  The IAB will continue to discuss this further.


3. IAB feedback and review for joint efforts
