eBPF Sockmap Ingress Core Routing Design

To mitigate the critical multi-turn prompt sequence re-tokenization overhead bill caused by mid-flight socket collapses, FaultPlane bypasses traditional application retry mechanisms entirely.

Kernel Redirection Mechanics

  1. Socket Interception: The proxy daemon attaches a low-overhead eBPF hook mapping BPF_MAP_TYPE_SOCKMAP properties.
  2. Sequence Snipping: Transparently isolates the exact byte metrics sequence matching the TCP Window In-Flight markers.
  3. Standby Splicing: In the event of an upstream container crash (tcp_set_state:TCP_CLOSE), the daemon redirects unacknowledged bytes stream tails onto healthy nodes within a sub-2ms threshold boundary, blocking runtime cross-boundary data leaks natively.
