The meeting focused on problem statements, solutions, and future plans in each area.

Key Discussion Points

Network Overlay Impacts:
- Review of the updated document (version 2).
- Discussion on potential unintended consequences of network overlays on streaming workflows, DNS resolution, and IP address assignment.
