We become annoyed when we run a speed test on our broadband provider only to find that, on a good day, we are getting maybe half of the rated download speed we are paying for, and the upload speed is likely much worse. But to prevent running afoul of latency (the 2 nd fallacy), we must also be careful not to download too little!

High-speed networks through 5G may represent the next generation of cord cutting. I don’t need more bandwidth for video conferences or movies, but I would like to be able to download operating system updates and other large items in seconds rather than minutes. Reliability will be an even bigger problem than latency.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Congestion Control.
