+## Network UI Implementation (2025-06-20) - COMPLETED
+
+### Overview
+Revamped the Network UI to display real network data from SmartProxy instead of mock data.
+
+### Architecture
+1. **MetricsManager Integration:**
+   - Already integrates with SmartProxy via `dcRouter.smartProxy.getStats()`
+   - Extended with `getNetworkStats()` method to expose unused metrics:
+     - `getConnectionsByIP()` - Connection counts by IP address
+     - `getThroughputRate()` - Real-time bandwidth rates (bytes/second)
+     - `getTopIPs()` - Top connecting IPs sorted by connection count
+   - Note: SmartProxy base interface doesn't include all methods, manual implementation required
+
+2. **Existing Infrastructure Leveraged:**
+   - `getActiveConnections` endpoint already exists in security.handler.ts
+   - Enhanced to include real SmartProxy data via MetricsManager
+   - IConnectionInfo interface already supports network data structures
+
+3. **State Management:**
+   - Added `INetworkState` interface following existing patterns
+   - Created `networkStatePart` with connections, throughput, and IP data
+   - Integrated with existing auto-refresh mechanism
+
+4. **UI Changes (Minimal):**
+   - Removed `generateMockData()` method and all mock generation
+   - Connected to real `networkStatePart` state
+   - Added `renderTopIPs()` section to display top connected IPs
+   - Updated traffic chart to show real request data
+   - Kept all existing UI components (DeesTable, DeesChartArea)
+
+### Implementation Details
+1. **Data Transformation:**
+   - Converts IConnectionInfo[] to INetworkRequest[] for table display
+   - Calculates traffic buckets based on selected time range
+   - Maps connection data to chart-compatible format
+
+2. **Real Metrics Displayed:**
+   - Active connections count (from server stats)
+   - Requests per second (calculated from recent connections)
+   - Throughput rates (currently showing 0 until SmartProxy exposes rates)
+   - Top IPs with connection counts and percentages
+
+3. **TypeScript Fixes:**
+   - SmartProxy methods like `getThroughputRate()` not in base interface
+   - Implemented manual fallbacks for missing methods
+   - Fixed `publicIpv4` → `publicIp` property name
+
+### Result
+- Network view now shows real connection activity
+- Auto-refreshes with other stats every second
+- Displays actual IPs and connection counts
+- No more mock/demo data
+- Minimal code changes (streamlined approach)
+
+### Throughput Data Fix (2025-06-20)
+The throughput was showing 0 because:
+1. MetricsManager was hardcoding throughputRate to 0, assuming the method didn't exist
+2. SmartProxy's `getStats()` returns `IProxyStats` interface, but the actual object (`MetricsCollector`) implements `IProxyStatsExtended`
+3. `getThroughputRate()` only exists in the extended interface
+
+**Solution implemented:**
+1. Updated MetricsManager to check if methods exist at runtime and call them
+2. Added property name mapping (`bytesInPerSec` → `bytesInPerSecond`)
+3. Created new `getNetworkStats` endpoint in security.handler.ts
+4. Updated frontend to call the new endpoint for complete network metrics
+
+The throughput data now flows correctly from SmartProxy → MetricsManager → API → UI.
