Does Netflix use RTP?

RTP also prevents transmitting faster than the link can support. For non real time video streaming, like Netflix, Hulu, Youtube, etc. they just use TCP and do buffering instead of UDP, since they don’t care about a few seconds delay between the server and client.

Is TCP or UDP better for streaming?

As for streaming it’s better to use UDP, first because it lowers the load on servers, but mostly because you can send packets with multicast, it’s simpler than sending it to each connected client. It depends. How critical is the content you are streaming? If critical use TCP.

Does SIP use RTP?
