Adding Cloudflare's TURN Network to Broadcast Bridge

Adding Cloudflare's TURN Network to Broadcast Bridge

In the realm of live streaming and real-time communication, reliable connectivity is paramount. Broadcast Bridge, leveraging WebRTC for low-latency interactions, now offers enhanced connectivity with the integration of Cloudflare's TURN (Traversal Using Relays around NAT) network. This article explores how Cloudflare's TURN network, through Cloudflare Calls, improves Broadcast Bridge's capabilities by providing access to over 300 points of presence worldwide.

Understanding TURN and Its Importance

WebRTC and TURN: WebRTC (Web Real-Time Communication) enables low-latency, peer-to-peer data transfer within browsers, bypassing the need for plugins or additional software. However, NAT (Network Address Translation) and firewalls often block direct connections between devices. This is where TURN comes into play. TURN servers relay data between peers when direct peer-to-peer connections fail, ensuring seamless communication even in restrictive network environments. Don't forget, a WebRTC peer can be a media server too.

When is TURN Used?: Most traffic in WebRTC applications flows directly between peers. However, in high-security environments, such as financial institutions, healthcare facilities, or government buildings, TURN usage can be much higher than the 3-4% (or so) of total traffic that's the norm.

Choosing a TURN Network

Broadcast Bridge supports several TURN network providers, including Twilio, Xirsys, and now Cloudflare. The criteria for selecting a TURN provider revolve around three main factors:

1. Connectivity: Ensuring connections can be established in challenging network environments.
2. Latency: Minimizing the time to first byte, which is critical for maintaining low-latency interactions.
3. Cost: Balancing the financial implications of relaying data through TURN servers.

Why Cloudflare?: Cloudflare's entry into the TURN market brings several advantages. Known for its extensive network infrastructure, Cloudflare offers over 300 points of presence worldwide. This extensive coverage ensures that users can connect to a nearby edge node, reducing latency and improving overall performance. Additionally, Cloudflare's reputation for security and reliability makes it an attractive option for Broadcast Bridge users.
