Inbound network traffic

[nieznanysprawiciel]

Design:

• Start designing inbound network traffic #1916
• https://github.com/golemfactory/golem-internal/issues/447
• https://github.com/golemfactory/golem-internal/issues/446
• Inbound network traffic market negotiation protocol spec #2009

Implementation:

Proxy implementation (woju):

1. Phase 1
   • TCP forwarding
   • Add/Remove listening endpoint
     • REST endpoints implementation
     • API client (for runtime): API client crate ya-runtime-net-gateway#4
2. Phase 2
   • UDP forwarding: Woju/devel ya-runtime-net-gateway#5
   • Collecting metrics: Collect connection metrics ya-runtime-net-gateway#3
   • Reporting metrics
     • Implement metrics in proxy client: Collect connection metrics ya-runtime-net-gateway#3
     • Endpoint for querying metric: Metrics API ya-runtime-net-gateway#6
3. TCP port checking: Port probing ya-runtime-net-gateway#7
4. UDP port checking

Core team:
POC (prerequisite: Proxy Phase 1):

• ya-runtime-net-gateway
  • Deploy command - check if proxy is running
  • Start command - run proxy if it wasn't running
  • Run command - creates endpoint on proxy
  • Remove proxy endpoint on close
  • Mock metric value
• Provider agent
  • Include IP/port in Offer (Requestor uses outbound or not)
  • Add ya-runtime-net-gateway descriptor
• Integration with VPN
  • Testing with VPN placeholder on golem side
  • Attaching real VPN to test full application flow

pre-MVP (prerequisite: Proxy Phase 2):

• Ports negotiations
• ya-runtime-net-gateway forwards metrics from Proxy

MVP (prerequisite: Proxy Phase 3):

• Proxy MVP
  • Proxy as autostart yagna extension
  • Checking if IP/port is really open on Provider
• KYC (Requestor identity)
  • ...
