Agenda
• OTT?
• OTT 4K?
• Can we actually stream 4K Over-The-Top?
• Why the Internet is not built for 4K OTT delivery
• What we can do about it

OTT is…Broadcasting of premium audio, video, and other media over the Internet without the control and/or ownership of the distribution network.
What is OTT?

Grow revenue opportunities with fast, personalized web experiences and manage complexity from peak demand, mobile devices and data collection.
TCP will trade speed / throughput for reliability:• The farther away the server (Round Trip Time)• When there is congestion / packet loss
TCP based transport (e.g HTTP) is built for reliability, not speedCHALLENGE:

20ms of latency, can reduce throughput by 23%
Average Round Trip TimeRTT (US) = 72ms • RTT (Global) = 94ms
*** Assuming average 64KB RWIN
How does latency and packet loss impact throughput?
