Runtime Engine Architecture
TServer Components
The Runtime Engine (TServer) is the heart of FrameworX execution:
| Component | Function | Key Features |
|---|---|---|
| Core Engine | Central coordinator | Module management, event routing, memory management |
| Tag Services | Real-time database | In-memory storage, microsecond updates, quality management |
| Module Host | Module execution | Dynamic loading, lifecycle management, isolation |
| Communication Layer | Network services | Client connections, protocol handlers, buffering |
| Security Context | Access control | Authentication, authorization, audit logging |
Memory Architecture
