Very impressed by the high quality discussions. Thanks to everyone that joined!

Topics we covered:

• Network measurement efforts GitHub - protocol/network-measurements
• rust-libp2p
  • Bitswap
    • It is an important building block for many peer-to-peer applications. We should have a solid implementation in rust-libp2p.
    • Tracking issue: Bitswap · Issue #2632 · libp2p/rust-libp2p · GitHub
  • Streaming response
    • Abstraction useful for many applications.
    • See it as an evolution on top of TCP, stream-based, secure, supporting protocol negotiation, able to hole punch, across various transport protocols, …
    • Add a streaming-response protocol to rust-libp2p · Issue #2657 · libp2p/rust-libp2p · GitHub
  • async-io
    • Discussion on whether we should continue supporting async-io.
    • Result: Keep supporting it. Ping upstream maintainers and make bug easier to reproduce.
    • relay_v2 performance anomaly on small machines · Discussion #2619 · libp2p/rust-libp2p · GitHub
  • Quic
    • What is the state of QUIC in rust-libp2p?
    • Progress is being made on Libp2p quic third attempt by kpp · Pull Request #2289 · libp2p/rust-libp2p · GitHub
    • Core abstractions are being refactored to cleanly support QUIC Transport: Poll Transport directly, remove ListenersStream by elenaf9 · Pull Request #2652 · libp2p/rust-libp2p · GitHub
• Testgraound
  • More and more resources being invested in the project in general.
  • Ability to send metrics to the central influxDB sdk-rust/client.rs at 9153d4a3e098337f7a88c2dcb8ad33759c6b7a0b · testground/sdk-rust · GitHub
  • Alternative product mentioned: https://antithesis.com/
  • Folks looking into improving gossipsub (episub / gossipsub 1.2), simulated via Testground Gossipsub extension for Epidemic Meshes (v1.2.0) by AgeManning · Pull Request #413 · libp2p/specs · GitHub
• Unreliable transports
  • Use case e.g. for VPNs, Streaming live data, Video games
  • E.g. to be implemented on top of unreliable data streams in QUIC RFC 9221 - An Unreliable Datagram Extension to QUIC
  • Plain UDP is most likely not what folks want (e.g. due to no back-pressure, no security, packet spoofing, …)
