Project Optimization
Communication Upgrade: HTTP Polling → WebSocket
- Upgraded communication protocol from HTTP polling to WebSocket
- Achieved full-duplex real-time communication, improving user experience
Upgrade Benefits:
✅ Enhanced Real-time Performance
- WebSocket supports server-side push, eliminating frequent client polling
- Message latency reduced from seconds to milliseconds, more responsive
✅ Significant Performance Improvement
- Reduced unnecessary HTTP request overhead, lower network bandwidth usage
- Maintains persistent connection after establishment, avoiding frequent connection setup/teardown overhead
- Significantly improved server resource utilization
✅ Optimized User Experience
- Smoother video transmission, reduced stuttering and latency
- Faster keyboard/mouse response, closer to local operation experience
- Lower network traffic consumption, especially suitable for mobile devices
✅ Enhanced Scalability
- Supports more efficient binary data transmission
- Lays foundation for future feature expansion (audio transmission, file transfer, etc.)
- Better connection management and error recovery mechanisms
Future Plans
- 🔄 Continue optimizing tunnel service performance
- 📦 Expand CDN image library support
- 🛠️ Enhance virtual USB functionality
- 🌐 Improve multi-language support
- 📱 Optimize mobile experience
