vac:p2p: §

• nimlibp2p:vac:webrtc-transport
  • Fix a bug in Datachannel.read (reading the last message received instead of the first one)
  • Fix a bug due to an Sctp delay (set it to 0ms was the solution)
  • Find a bug in the conception of WebRTCStream. ReadOnce should be Length-prefixed.
    • try to fix it by re-writing ReadOnce, but due to the nature of this proc (inheritance issue) it doesn’t work
    • write a RawWebRTCStream to make the length readable without issue
  • Fix a bug with the endianness of the datachannel protocol id
  • E2E Done!
• nimlibp2p:vac:gossipsub-stagger-send
  • feat: make relayed messages non priority (don’t use an explicit queue for priority msgs) - https://github.com/status-im/nim-libp2p/pull/1015
  • feat: drop msgs to be relayed waiting for too long in the queue - https://github.com/status-im/nim-libp2p/pull/1015
• nimlibp2p:vac:maintenance
  • Investigate dependencies issues
    • Found possible problem/s
      • Lack of versioning
      • No major version clamping
      • Using#head
    • Temporary workaround: Clamp/Pin (to git hash) libp2p dependencies’ versions
      • PR
  • Improve documentation [In Progress]
    • Building go-libp2p-daemon
    • Getting Started
    • PR
  • Merge timeout increase
  • Improved checkExpiring
    • Now it’ll outpout an error message when it fails due to timeout
      • Not the most visible message

vac:dst: §

• eng-10ktool:vac:bandwidth-test
  • Try to get a stable nim-libp2p version for simulations. Investigated with Alex about building issues with nimble.
  • Analized libp2p metrics, everything normal so far
  • call with p2p team
  • Scale testing for 10K project
    • setup go-waku experiment at scale
    • Successfully simulated a 2,150 node simulation and gathered some basic metrics
    • Modified Kubernetes to allow for more pods to allow for (in theory) scaling to 10k+
    • Failed simulations at 10000 and 5000 nodes - current limits seem to be around ~4800 or so
    • Prometheus is a definite bottleneck - need to switch to a scaled/sharded Prometheus/Thanos setup
    • Attempting one last simulation over the weekend at 4200 nodes
  • Diagnosing 10K project bottlenecks
    • Identified a major potential bottleneck in the form of control plane traffic going over Wireguard / large packet load over WG causing swarm collapse
    • will test the new theory later by re-deploying on Vac Kubernetes with a local control plane + local traffic (while still complying with infra team requirements)
