-
Traffic Distribution: Outgoing packets are distributed across all healthy WANs based on:
- Bandwidth capacity (weight)
- Current latency
- Packet loss rate
- Connection state
-
Health Monitoring: Each WAN is continuously monitored:
- Ping/HTTP/DNS/TCP checks every 200-1000ms
- Adaptive check intervals based on stability
- Sub-second failure detection (<1s)
- Automatic failover when WAN goes down
-
Packet Reordering: Received packets are reordered:
- Sequence numbers ensure correct order
- Configurable timeout (default 500ms)
- Handles out-of-order delivery from multiple paths
-
DPI Classification: Traffic is classified in real-time:
- Extracts protocol information (HTTP, HTTPS, YouTube, etc.)
- Categorizes by application type
- Enables policy-based routing
-
Security: All traffic is encrypted:
- ChaCha20-Poly1305 or AES-256-GCM
- Pre-shared key or certificate-based auth
- Automatic key rotation
