> In most households having a limited single-stream throughput isn't a big deal, but it IS a big deal specifically for things like your 4K streaming. It's VERY difficult to do TRUE sustained 4K streaming over any kind of distance. If your ISP happens to have a Netflix caching box at the local pop you're golden. If you need to traverse any kind of distance across the internet - good luck.

We're talking about TCP - but most 4K streaming shouldn't be using TCP though, right? Especially not if you actually have 100MB/s bandwidth.



I'm happy if someone has a reference stating otherwise, but it's my understanding that both Youtube and Netflix utilize TCP for their video streams whether it's 4K or not.


If they use TCP then it's because they feel like it works over real-world networks.

If they need to use UDP, they will. 4K is eminently feasible, and can require a connection faster than 100mbps with a mere two streams.


Video buffering. With TCP you can ensure delivery of the traffic ahead of time, retransmitting if necessary before a particular segment needs to be played.


All Internet streaming is now over HTTP.
