Crate entrouter_line 

entrouter-line - zero-loss cross-region packet relay mesh.

Builds encrypted UDP tunnels between PoP nodes, adds adaptive FEC to absorb packet loss, and routes traffic over the lowest-latency path using live Dijkstra on a continuously-probed latency matrix.

Architecture

• edge - User-facing TCP and QUIC acceptors that locally ACK traffic and relay it through the mesh.
• relay - Encrypted tunnel transport with FEC, wire framing, and multi-hop forwarding.
• mesh - Latency probing, EWMA smoothing, and shortest-path routing.
• admin - Lightweight HTTP server for health checks and status.
• config - TOML configuration loading and validation.
