Summary

This session of the panrg meeting focused primarily on the SCION (Scalability, Control, and Isolation on Next-Generation Networks) architecture. Presentations covered an API for retrieving energy consumption data from the network, the SCION control and data planes, operational aspects of SCION deployments, and a specific use case within the Swiss financial industry. The session concluded with a discussion on the future direction of SCION-related work within the IETF/IRTF, exploring options for standardization and further research.

Key Discussion Points

Energy API:
- Presentation on an API for retrieving energy consumption information from network paths, considering both baseline and traffic-dependent energy usage.
- Discussion about including energy source information in the API and aligning with carbon-aware networking initiatives.
SCION Architecture:
- Overview of SCION's control plane (beaconing, registration, resolution), data plane (hop-by-hop forwarding based on header information), and PKI (trust model).
- Discussion of security considerations, including path hijacking prevention and inter-domain authentication.
SCION Deployments and Operations:
- Explanation of the SCION Internet ecosystem, including backbones, isolation domains, and edge gateways.
- Details on bootstrapping new isolation domains, acquiring AS numbers and certificates, and setting up peering relationships.
- Description of IP-in-SCION tunneling as a common deployment model.
- Use case examples in Swiss finance and healthcare, highlighting benefits like high availability, resilience, and controlled governance.
SCION Standardization and Research:
- Call for standardization to foster ecosystem growth, interoperability, and broader adoption.
- Discussion of open research questions, including interoperability, transition mechanisms, naming, and operational aspects.
- Exploration of potential synergies with other technologies like LISP and RPKI.

Decisions and Action Items

SCION Drafts: Consider adoption of the three core SCION drafts as implementation drafts within the PanRG.
Mailing List Discussion: The chairs will initiate a discussion on the panrg mailing list to formally propose adoption of the SCION implementation drafts.
Future Meetings: Chairs will consider scheduling subsequent panrg meetings with more SCION-related content, particularly at IETF 118 in Brisbane.

Next Steps

Chairs to phrase the adoption proposal and post it to the panrg mailing list.
Community to discuss the proposal and express interest.
Continue conversations with IETF area directors regarding next steps for SCION standardization.
