NNCP: Lossless Data Compression with Neural Networks (2019)

That seems very atypical. As the link capacity ratio goes past 10:1, even for typical dowloads, speed starts to be limited by the ability to send requests, or even TCP ACKs.

I've seen 20:1 offers on cable providers, but it's mostly marketing BS, as you're unlikely to get full download speed in most circumstances due to upload limitations.

True - my nominal bandwidth (i.e. what I pay for) is 1000/50.

I do reach the full downlink speed though due to (presumably) ACK compression in the modem and ACK synthesis/reexpansion in the CMTS. You are right that otherwise such a high ratio would not be feasible with TCP.

Plain single-stream download-only TCP should fit without compression, probably even without Delayed ACKs.

IME, the line starts to choke when you actually want to send requests and they compete with ACKs and your internet stutters and crawls in both direction. Though that was with a slower connection - it's harder to fill a bigger pipe.

BTW, is the ACK compression counted for consumers benefit?
