UDP Relay Architecture

Client Browser ──[UDP chunks]──▶ Dragon Wind Relay ──[S3 Multipart]──▶ S3
              ◀──[TCP ACK]────── (port 5000 UDP)       (port 3001 API)

The relay handles:

• UDP chunk reception with sequence numbers
• S3 multipart upload assembly
• Forward error correction via retransmission
• Session lifecycle management
