## 🎯 **Advanced Pattern Matching**

### 🔍 **Pattern Operations**

UPAS v1.0.x provides advanced pattern matching capabilities for complex payload analysis:

#### **CAPTURE Operations**

Extract dynamic values from incoming packets:

```json
"payload_pattern": "[PREFIX:11]40ffff0000ffffffff0804000000[FMBOX_ID:4]0000000600000021[CAPTURE:TCP_PORT:2]0000c0a851fd[SUFFIX:4]"
```

**Features:**

- ✅ **Variable Storage**: Captured values stored globally for reuse
- ✅ **Type Conversion**: Automatic hex → decimal conversion with `:int`
- ✅ **Size Specification**: Exact byte count for capture operations
- ✅ **Real-time Processing**: Immediate availability for response generation

#### **WILDCARD & SKIP Operations**

Handle variable content without capture:

```json
"payload_pattern": "[PREFIX:8][WILDCARD:16][DATA_FIELD:4][SKIP:8][SUFFIX:4]"
```

**Use Cases:**

- **Dynamic Fields**: Skip variable-length or dynamic content
- **Unknown Padding**: Handle protocol padding or reserved fields
- **Flexible Matching**: Match patterns with known variable portions

#### **Advanced Examples**

```json
{
  "complex_parser": {
    "type": "reactive",
    "trigger": {
      "payload_pattern": "[PREFIX:8][CAPTURE:TYPE:1][WILDCARD:4][CAPTURE:LENGTH:2][CAPTURE:DATA:*][SUFFIX:4]"
    },
    "response": {
      "destination": "sender",
      "payload": ["[PREFIX:8]RESPONSE_[TYPE:1]_LEN_[LENGTH:2][SUFFIX:4]"]
    }
  }
}
```

### 🎯 **Pattern Processing Pipeline**

```
Raw Payload → Pattern Tokenization → Operation Execution → Variable Storage → Response Generation
     ↓               ↓                      ↓                    ↓                 ↓
"804721C7..."  → [PREFIX:8][CAPTURE:ID:4] → Extract 4 bytes → Store ID=1234 → Use [ID:4] in response
```

### 📊 **Pattern Performance**

| Operation         | Speed   | Memory Usage | Use Case             |
| ----------------- | ------- | ------------ | -------------------- |
| **CAPTURE**       | ~0.1ms  | Low          | Variable extraction  |
| **WILDCARD**      | ~0.05ms | Minimal      | Skip unknown content |
| **SKIP**          | ~0.05ms | Minimal      | Skip known content   |
| **PREFIX/SUFFIX** | ~0.02ms | Minimal      | Static matching      |

---

## 🚀 **Multi-Packet Response System**

### 📦 **Response Modes**

UPAS supports sophisticated multi-packet response strategies for complex protocols:

#### **1. Sequential Responses**

Send packets in order with ACK validation and retry logic:

```json
"response": {
  "mode": "sequence",
  "packets": [
    {
      "id": "handshake",
      "payload": "[PREFIX:11]HANDSHAKE_DATA[SUFFIX:4]",
      "timeout": 5.0,
      "max_retries": 3
    },
    {
      "id": "data_transfer",
      "payload": "[PREFIX:11]ACTUAL_DATA[SUFFIX:4]",
      "delay": 0.1
    }
  ],
  "global_timeout": 30.0,
  "fail_fast": true
}
```

**Features:**

- ✅ **Timeout Control**: Individual packet timeouts with retry logic
- ✅ **Failure Handling**: `fail_fast` stops sequence on first failure
- ✅ **Global Timeout**: Overall sequence timeout protection
- ✅ **Delay Control**: Inter-packet timing configuration

#### **2. Burst Responses**

Send multiple packets in parallel:

```json
"response": {
  "mode": "burst",
  "packets": [
    {"id": "notify_a", "payload": "[PREFIX:4]NOTIFY_A[SUFFIX:2]"},
    {"id": "notify_b", "payload": "[PREFIX:4]NOTIFY_B[SUFFIX:2]"},
    {"id": "notify_c", "payload": "[PREFIX:4]NOTIFY_C[SUFFIX:2]"}
  ]
}
```

**Use Cases:**

- **Broadcast Notifications**: Send notifications to multiple destinations
- **Parallel Processing**: Independent packet transmission
- **High-Throughput Protocols**: Maximum transmission speed

#### **3. Delayed Sequential Responses**

Sequential transmission with custom timing:

```json
"response": {
  "mode": "delayed_sequence",
  "packets": [
    {"id": "immediate", "payload": "IMMEDIATE_RESPONSE", "delay": 0.0},
    {"id": "delayed", "payload": "DELAYED_RESPONSE", "delay": 2.0},
    {"id": "final", "payload": "FINAL_RESPONSE", "delay": 5.0}
  ]
}
```

### 🔧 **Response Configuration**

#### **Packet Options**

| Option        | Type         | Description                    | Default  |
| ------------- | ------------ | ------------------------------ | -------- |
| `id`          | string       | Unique packet identifier       | Required |
| `payload`     | string/array | Packet payload data            | Required |
| `destination` | string       | Target address:port            | "sender" |
| `delay`       | float        | Delay before sending (seconds) | 0.0      |
| `timeout`     | float        | ACK timeout (seconds)          | 5.0      |
| `max_retries` | int          | Maximum retry attempts         | 3        |

#### **Global Options**

| Option           | Type   | Description                                            | Default  |
| ---------------- | ------ | ------------------------------------------------------ | -------- |
| `mode`           | string | Response mode (single/sequence/burst/delayed_sequence) | "single" |
| `global_timeout` | float  | Overall timeout for all packets                        | 30.0     |
| `fail_fast`      | bool   | Stop on first failure                                  | false    |

### 📊 **Performance Metrics**

Multi-packet responses include comprehensive performance tracking:

```
🚀 Response Performance:
   • Total Packets: 3/3 sent successfully
   • Sequence Time: 2.14 seconds
   • Retry Count: 0 failures
   • Success Rate: 100%
```

---

## 🔄 **State Machine Management**

### 🎛️ **State Definition**

Define protocol states with comprehensive lifecycle management:

```json
"state_machine": {
  "initial_state": "DISCOVERING",
  "states": {
    "DISCOVERING": {
      "description": "Device discovery phase",
      "entry_action": "start_discovery_timer",
      "exit_action": "stop_discovery_timer"
    },
    "PHASE0": {
      "description": "Initial connection phase",
      "entry_action": "start_connection_process"
    },
    "CONNECTED": {
      "description": "Established session",
      "entry_action": "start_keepalive"
    }
  },
  "transitions": [
    {
      "from": "DISCOVERING",
      "to": "PHASE0",
      "trigger": "manual",
      "action": "start_phase0_process"
    }
  ]
}
```

### � **Behavior-Driven Transitions**

Behaviors can trigger automatic state transitions:

#### **Simple State Transition**

```json
"init_behavior": {
  "type": "reactive",
  "trigger": {"payload_pattern": "[PREFIX:8]CONNECT_REQ[SUFFIX:4]"},
  "response": {"payload": ["[PREFIX:8]CONNECT_ACK[SUFFIX:4]"]},
  "transition": "CONNECTED"  // Transition on successful execution
}
```

#### **Conditional Transitions**

```json
"connection_behavior": {
  "type": "one_shot",
  "response": {"payload": ["[PREFIX:8]INIT_DATA[SUFFIX:4]"]},
  "transition": {
    "success": "CONNECTED",
    "error": "ERROR"
  }
}
```

### 🎯 **State-Only Behaviors**

Pure state transitions without packet sending:

```json
"timeout_behavior": {
  "type": "state_only",
  "active_states": ["DISCOVERING"],
  "delay": 30000,              // 30 seconds
  "transition": "ERROR"        // Transition to ERROR after timeout
}
```

**Features:**

- ✅ **Timeout Handling**: Automatic state transitions after delays
- ✅ **No Network Traffic**: Pure state machine operation
- ✅ **Error Handling**: Timeout-based error recovery

### 🔄 **Behavior Lifecycle Management**

#### **Automatic Restart Logic**

The BehaviorExecutor automatically restarts one-shot behaviors when entering new states:

```python
# Automatic behavior restart on state change
if behavior_type == "one_shot" and new_state in behavior.active_states:
    behavior_executor.restart_behavior(behavior_id)
```

#### **State Filtering**

Behaviors only execute in specified states:

```json
"udp_keepalive": {
  "type": "periodic",
  "active_states": ["DISCOVERING", "CONNECTED"],  // Only run in these states
  "interval": 1000
}
```

## 🌐 **Service-Aware Transport**

### 🛠️ **Transport Architecture**

UPAS v1.0.x features an advanced transport layer with automatic service routing:

```json
"transports": {
  "ethernet": {
    "type": "ethernet",
    "interface": "tap0",
    "promiscuous": true,
    "services": {
      "udp_service": {
        "type": "udp_unicast",
        "bind_port": 7001
      },
      "tcp_client": {
        "type": "tcp_client"
      },
      "udp_multicast": {
        "type": "udp_multicast",
        "bind_port": 7001,
        "multicast_group": "224.0.10.13"
      }
    }
  }
}
```

### 🎯 **Service Types**

#### **UDP Services**

```json
{
  "udp_unicast": {
    "type": "udp_unicast",
    "bind_port": 8080,
    "reuse_port": true
  },
  "udp_multicast": {
    "type": "udp_multicast",
    "bind_port": 7001,
    "multicast_group": "224.0.10.13",
    "ttl": 5
  }
}
```

#### **TCP Services**

```json
{
  "tcp_server": {
    "type": "tcp_server",
    "bind_port": 9090,
    "max_connections": 10,
    "keepalive": true
  },
  "tcp_client": {
    "type": "tcp_client",
    "auto_reconnect": true,
    "reconnect_interval": 5000
  }
}
```

### 🔄 **Automatic Service Routing**

Behaviors automatically use the correct service based on their configuration:

```json
"tcp_behavior": {
  "type": "one_shot",
  "transport": "ethernet",
  "service": "tcp_client",    // Explicitly specify service
  "destination": "192.168.1.100:8080",
  "payload": ["TCP_DATA"]
}
```

**Service Selection Logic:**

1. **Explicit Service**: Use `service` field if specified
2. **Transport Default**: Use transport's default service
3. **Protocol Detection**: Auto-detect based on destination format
4. **Fallback**: Default to UDP unicast

### 🛡️ **Socket Management**

Advanced socket handling with fallback mechanisms:

```python
# Fallback socket creation methods
try:
    sock = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_UDP)
except PermissionError:
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# Automatic socket options
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
if hasattr(socket, 'SO_REUSEPORT'):
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, 1)
```

---

## � **Programmatic API**

UPAS v1.0.x provides a comprehensive Python API for integrating protocol simulation directly into your applications.

### 📦 **Installation for Programming**

```bash
# Standard installation
pip install upas

# Import in your Python code
import upas
```

### 🚀 **Quick Start API**

```python
import asyncio
import upas

async def main():
    # Simple protocol execution
    manager = await upas.run_protocol('protocol.json', duration=30)
    print(f"Execution completed in state: {manager.get_current_state()}")

# Run the example
asyncio.run(main())
```

### 🎯 **Core API Functions**

#### **High-Level Protocol Execution**

```python
import upas

# Method 1: Direct execution
manager = await upas.run_protocol('protocol.json', duration=60, verbose=True)

# Method 2: Manager-based control
manager = upas.ProtocolManager('protocol.json')
await manager.start_async(duration=120)
manager.stop()
```

#### **Protocol Data Manipulation**

```python
# Load protocol data
protocol_data = upas.load_protocol('protocol.json')
print(f"Protocol: {protocol_data['protocol']['name']}")

# Modify protocol programmatically
protocol_data['variables']['TIMEOUT'] = 5000
manager = upas.ProtocolManager(protocol_data)
```

#### **State Control**

```python
# Manual state transitions
manager = upas.ProtocolManager('protocol.json')
await manager.start_async(duration=5)

# Force state change
success = manager.transition_to_state('CONNECTED')
if success:
    print("Successfully transitioned to CONNECTED")

# Monitor current state
current_state = manager.get_current_state()
print(f"Current state: {current_state}")
```

### 🔄 **Dynamic Protocol Switching**

One of UPAS's most powerful features is the ability to switch protocols during execution:

```python
import upas

async def protocol_switching_example():
    # Start with discovery protocol
    manager = upas.ProtocolManager('discovery.json')

    # Register callback for protocol changes
    def on_protocol_change(new_protocol):
        name = new_protocol['protocol']['name']
        print(f"Switched to protocol: {name}")

    manager.on_protocol_change('switch_logger', on_protocol_change)

    # Execute discovery phase
    await manager.start_async(duration=15)

    # Switch to operational protocol
    await manager.change_protocol('operational.json')

    # Continue with new protocol
    await asyncio.sleep(30)

    # Switch to maintenance mode
    await manager.change_protocol('maintenance.json')

    await asyncio.sleep(10)
    manager.stop()

# Run the example
asyncio.run(protocol_switching_example())
```

### 📊 **Variable Management**

```python
# Real-time variable control
manager = upas.ProtocolManager('protocol.json')
await manager.start_async(duration=5)

# Get current variables
variables = manager.get_variables()
print(f"Current variables: {variables}")

# Modify variables during execution
manager.set_variable('RETRY_COUNT', 3)
manager.set_variable('SERVER_IP', '192.168.1.100')
manager.set_variable('DEBUG_MODE', True)

# Variables are immediately available to the protocol
updated_vars = manager.get_variables()
print(f"Updated variables: {updated_vars}")
```

### 🎣 **Event Callbacks**

```python
def setup_advanced_callbacks():
    manager = upas.ProtocolManager('protocol.json')

    # State-specific callbacks
    def on_discovering():
        print("🔍 Discovery started - adjusting scan parameters")
        manager.set_variable('SCAN_INTERVAL', 500)

    def on_connected():
        print("✅ Connection established - starting data flow")
        manager.set_variable('DATA_RATE', 'HIGH')
        manager.set_variable('HEARTBEAT_INTERVAL', 1000)

    def on_error():
        print("❌ Error detected - initiating recovery")
        manager.set_variable('RECOVERY_MODE', True)
        # Could also trigger protocol switch
        # await manager.change_protocol('recovery.json')

    # Register all callbacks
    manager.on_state_change('DISCOVERING', on_discovering)
    manager.on_state_change('CONNECTED', on_connected)
    manager.on_state_change('ERROR', on_error)

    return manager
```

### 🏗️ **Engine-Level Control**

For advanced users who need direct engine access:

```python
import upas

async def engine_control():
    # Create engine directly
    engine = await upas.create_engine('protocol.json')

    # Access engine components
    print(f"State machine: {engine.state_machine}")
    print(f"Transport layer: {engine.transport_layer}")

    # Start engine
    await engine.start()

    # Monitor engine statistics
    while engine.is_running():
        stats = engine.get_statistics()
        print(f"State: {stats['current_state']}")
        print(f"Behaviors: {stats['behaviors']}")
        await asyncio.sleep(5)

    await engine.stop()
```

## 🔧 **Troubleshooting**

### 🚨 **Common Issues**

<details>
<summary><strong>🔍 Low Pattern Detection Rate</strong></summary>

**Problem**: UPAS detects <80% pattern coverage

**Solutions**:

1. **Increase capture size**: Analyze more packets for better pattern detection
2. **Check target filter**: Ensure correct target IP is specified
3. **Frame range**: Focus on steady-state communication (skip initialization)
4. **Protocol variation**: Some protocols have variable headers/footers

```bash
# Try with larger frame range
./src/upas/cli.py analyze capture.json --target IP --start-frame 100 --end-frame 2000
```

</details>

<details>
<summary><strong>⏱️ Incorrect Timing Detection</strong></summary>

**Problem**: Periodic behaviors classified as irregular

**Solutions**:

1. **Network jitter**: Increase timing tolerance in analysis
2. **Capture quality**: Ensure stable capture environment
3. **Multi-device interference**: Filter to single device traffic

```bash
# Use verbose mode to see timing analysis
./src/upas/cli.py analyze capture.json --target IP -v
```

</details>

<details>
<summary><strong>🔗 Missing Trigger-Response Pairs</strong></summary>

**Problem**: No reactive behaviors detected

**Solutions**:

1. **Time window**: Triggers may occur outside analysis window
2. **Multi-packet triggers**: Some responses need multiple triggers
3. **Delay tolerance**: Increase correlation time window

```bash
# Analyze longer timeframe
./src/upas/cli.py analyze capture.json --start-frame 50 --end-frame 500
```

</details>

### 📊 **Performance Optimization**

#### Large Capture Files

```bash
# For captures >10MB
./src/upas/cli.py analyze huge_capture.json \
    --target 192.168.1.100 \
    --batch-size 1000 \
    --memory-limit 512MB
```

#### High-Frequency Protocols

```bash
# For protocols >100Hz
./src/upas/cli.py analyze high_freq.json \
    --target 192.168.1.100 \
    --timing-tolerance 0.5 \
    --counter-detection aggressive
```

### 🔍 **Debug Mode**

```bash
# Enable debug logging
export UPAS_DEBUG=1
./src/upas/cli.py analyze capture.json --target IP -v
```
