WebRTC vs WebSockets: Choosing the Right Stream

The Network Protocol Divide

When building real-time applications (Chat, Video, Stock Tickers), developers immediately reach for WebSockets. But WebSockets operates over TCP.

TCP is highly reliable. It guarantees packet delivery order and re-transmits lost packets. But this produces "Head-of-Line Blocking." If packet #2 drops, packet #3 and #4 are stalled until #2 is resent.

Enter WebRTC & UDP

For video streaming or intense gaming, waiting for a lost frame makes the application completely unusable. WebRTC operates predominantly over UDP. It fires packets continuously without waiting for acknowledgment.

If a video frame is dropped, WebRTC skips it and keeps rendering the present.

Our Routing Matrix:

• Financial Tickers / Text Chat: Secure WebSockets. We need guaranteed state in chronological order.
• Audio / Video / Telemetry Streaming: WebRTC Data Channels. Minimum latency is prioritized over absolute integrity of every single packet.
