Strategies to reduce RTT and packet loss in global video streaming applications
In real-time communication, every millisecond counts. A delay of more than 200ms can make a conversation feel unnatural. While P2P is the fastest, about 20-30% of global WebRTC calls require a TURN relay.
The Geographic Factor If your TURN server is in New York and your users are in Tokyo, their data must travel across the ocean twice. This adds massive Round-Trip Time (RTT). To optimize quality, you should deploy a "Geo-DNS" or "Anycast" setup where users connect to the TURN server closest to them.
Monitoring Metrics Using our ICE testing tool, pay attention to the "Response Time." A response under 50ms indicates a local or high-quality route, while anything over 200ms suggests potential lag during actual calls.
Security vs. Performance Using TURNS (TURN over TLS) on port 443 provides the best compatibility with restrictive firewalls but adds a slight overhead due to the TLS handshake. For most apps, standard TURN over UDP is preferred for speed.
