Summary

The ICNRG meeting included presentations on clock synchronization in information-centric networks, ICN applications for cybernetic avatars and metaverse environments, and a decentralized social media protocol called AtProto. Updates were provided on the status of the chunking draft, and a call for participation in draft reviews was issued. The next meeting is planned for Montreal.

Key Discussion Points

Clock Synchronization: Kathleen Nichols presented on clock synchronization in limited domains using the DEFT transport. The discussion focused on self-contained virtual clocks, collection-based communication, and failure-tolerant approaches. Quantization of differences and round-trip delay estimation were also covered.
Cybernetic Avatars and Metaverse: Yusak Hayamizu discussed ICN-based applications for cybernetic avatars (CA) and metaverse environments, including sharing teleoperation for multiple avatar robots and XR-based remote experiments. The C4 software, a CCNX 1.0 compliant implementation, was introduced.
AtProto: Decentralized Social Media: Daniel Holmgren presented AtProto, a decentralized social media protocol. Key aspects included location-independent and self-certifying data, user-rooted authority, generic data hosting, and a credible exit strategy. Addressing scheme using AT URIs was highlighted.
Chunking Draft: Hitoshi Asaeda provided a brief update, stating that the chunking draft is almost ready for last call. Community members were encouraged to review and provide feedback.
Draft Reviews: A strong call for participation in reviewing current drafts, specifically flick and reflexive forwarding, was made. More community input is needed to move these drafts forward.

Decisions and Action Items

Chunking Draft Last Call: If no objections are raised within the next couple of weeks, the chunking draft will be submitted for a research group last call.
- Action: ICNRG Chairs (Lange/Cochetti) to send a message to the mailing list soliciting objections to last call.
Flick Re-Spin: Re-spin flick and issue a second last call in the next couple of months
- Action: Spin and issue a second last call.

Next Steps

Submit chunking draft for research group last call (contingent on mailing list feedback).
