What will be expected maximum throughput over TCP/IP with 5s ping, with 0% packet loss, 0.1% packet loss and 1% packet loss?
Hypothetical question with no real-world application.
1. The guy talks about "5s ping". That means 2500ms latency one-way.
2. You will not find 2500ms latency anywhere in the world. You did not even find that in 1994.
3. Even satellite will provide better than that: ~300ms.
4. Your question lacks an important parameter: bandwidth and server/receiver memory.
As long as you have enough memory, you can store the entire transmission without acking.
