## Mobile Network Resilience
|
||||
|
||||
HMAC File Server 3.2 introduces enhanced network resilience specifically designed for mobile devices and network switching scenarios.
|
||||
|
||||
### 📱 **Mobile Network Switching Support**
|
||||
|
||||
#### **Scenario 1: WLAN ↔ IPv6 5G Switching**
|
||||
Perfect for mobile devices that switch between WiFi and cellular networks:
|
||||
|
||||
```toml
|
||||
[server]
|
||||
networkevents = true # REQUIRED: Enable network monitoring
|
||||
|
||||
[network_resilience]
|
||||
fast_detection = true # 1-second detection vs 5-second default
|
||||
quality_monitoring = true # Monitor connection quality
|
||||
predictive_switching = true # Switch before network fails
|
||||
mobile_optimizations = true # Cellular-friendly settings
|
||||
|
||||
[uploads]
|
||||
session_recovery_timeout = "600s" # 10-minute recovery window for IP changes
|
||||
client_reconnect_window = "300s" # 5-minute reconnection window
|
||||
max_resumable_age = "72h" # Extended session retention
|
||||
max_upload_retries = 8 # More retries for cellular
|
||||
|
||||
[timeouts]
|
||||
readtimeout = "600s" # Extended for cellular latency
|
||||
writetimeout = "600s" # Handle cellular upload delays
|
||||
idletimeout = "1200s" # 20-minute tolerance
|
||||
```
|
||||
|
||||
#### **Scenario 2: Dual-Connected Devices (Wired + WiFi)**
|
||||
For devices with multiple network interfaces:
|
||||
|
||||
```toml
|
||||
[network_resilience]
|
||||
fast_detection = true # Quick interface change detection
|
||||
quality_monitoring = true # Monitor both connections
|
||||
predictive_switching = true # Use best available interface
|
||||
|
||||
# System automatically selects best interface based on:
|
||||
# - RTT (latency)
|
||||
# - Packet loss percentage
|
||||
# - Connection stability
|
||||
# - Interface priority (ethernet > wifi > cellular)
|
||||
```
|
||||
|
||||
### **Benefits for Mobile Scenarios**
|
||||
|
||||
| Feature | Standard Detection | Enhanced Mobile Detection |
|
||||
|---------|-------------------|---------------------------|
|
||||
| **Detection Speed** | 5 seconds | **1 second** |
|
||||
| **Network Quality** | Interface status only | **RTT + packet loss monitoring** |
|
||||
| **Switching Logic** | Reactive (after failure) | **Proactive (before failure)** |
|
||||
| **Mobile Tolerance** | Fixed thresholds | **Cellular-optimized thresholds** |
|
||||
| **Session Recovery** | 2-minute window | **10-minute window** |
|
||||
| **Upload Resumption** | Basic retry | **Smart retry with backoff** |
|
||||
|
||||
### **Configuration Examples**
|
||||
|
||||
**Ultra-Fast Mobile Detection**:
|
||||
```toml
|
||||
[network_resilience]
|
||||
detection_interval = "500ms" # Sub-second detection
|
||||
quality_check_interval = "2s" # Frequent quality checks
|
||||
mobile_optimizations = true # Lenient cellular thresholds
|
||||
```
|
||||
|
||||
**Conservative Stable Network**:
|
||||
```toml
|
||||
[network_resilience]
|
||||
detection_interval = "10s" # Slower detection
|
||||
quality_monitoring = false # Disable quality checks
|
||||
predictive_switching = false # React only to hard failures
|
||||
```

# 1. Set networkevents = true in [server] section to enable network monitoring
|
||||
# 2. fast_detection = true enables 1-second polling instead of 5-second polling
|

# 3. quality_monitoring = true adds RTT and packet loss monitoring
|

# 4. predictive_switching = true switches networks proactively before complete failure
|

# 5. mobile_optimizations = true uses mobile-friendly thresholds (higher RTT tolerance, etc.)

# 6. Extended timeouts and retry counts help with mobile network instability
|

# 7. Longer session persistence accommodates network switching delays
|

|

# Mobile Network Switching Benefits:
|
||||
# • WLAN ↔ 5G IPv6 switching: Fast detection (1s) + predictive switching
|
||||
# • Dual connectivity (Wired + WiFi): Quality monitoring selects best interface
|
||||
# • Cellular optimization: Higher RTT/packet loss tolerance + more retries
|
||||
# • Session mobility: 10-minute recovery window for IP address changes
|
||||
# • Proactive switching: Network degradation detected before complete failure
