Client-Server Architecture
Multiplayer games use client-server or peer-to-peer networking:
- Authoritative Server: Server validates all actions
- Client Prediction: Smooth local gameplay
- Server Reconciliation: Correct client predictions
- Lag Compensation: Handle network delays
Data Synchronization
Keep game states synchronized:
- State replication
- Delta compression
- Priority-based updates
- Interest management
Network Protocols
- TCP: Reliable, ordered delivery
- UDP: Fast, unreliable delivery
- WebRTC: Peer-to-peer connections
Latency Compensation
- Client-side prediction
- Server reconciliation
- Interpolation and extrapolation
- Lag compensation techniques
Security Considerations
- Validate all client inputs
- Encrypt sensitive data
- Prevent cheating
- Rate limiting
Conclusion
Robust network programming enables responsive multiplayer experiences by balancing performance, synchronization, and security across distributed game clients.
