Network Architecture
Data Path
The data ports operate as a transparent layer-2 bridge:
| Setting | Value |
|---|
| IP address | None (silent on network) |
| ARP/IPv6/LLDP/STP | Disabled |
| Mode | Promiscuous |
| Forwarding | Bridge (transparent inline) |
The appliance is invisible to the network under test. All frames are forwarded between data ports with optional impairment injection.
Management Network
| Setting | Value |
|---|
| DHCP | Enabled (60 second timeout) |
| Fallback | Link-local (169.254.x.y) |
| mDNS | Advertises as jt-XXXX.local |
| Firewall | HTTPS (443), mDNS (5353) only |
Security
| Feature | Implementation |
|---|
| HTTPS | TLS with self-signed certificate (user replaceable) |
| Authentication | Unique per-device password (printed on label) |
| Password Change | Supported via web UI |
| API Access | Token-based authentication |
| Data Ports | No IP stack, no listening services |
Software
| Component | Description |
|---|
| Operating System | Custom Linux image |
| Application | JitterTrap |
| Interface | Web UI (browser-based) |
| API | REST API for automation |
