What is it about the upstream that causes more congestion? And as you say "especially in DOCSIS"?
I'm not aware of anything with DOCSIS that requires the up-speed to be so low. It's just a matter of the cable ISPs not using as many channels for up-speed because on average a residential connection doesn't NEED a ton of up-speed.
Now if they're just not building out their networks to have a lot of up-speed bandwidth at the node level then that's another discussion.
It really seems to me that much of this content is likely consumed by many households within a node. It does seem kinda foolish that it's streamed multiple times to multiple residences within a neighborhood when the content could easily live somewhere on that node. I guess it just comes down to what is cheaper? Bandwidth or storage? Seems they're deciding it's bandwidth which makes one question why we need data caps on residential broadband.
- wmf 7y agoDue to the frequency split there are fewer upstream channels available and changing that would require replacing all the filters. Downstream bandwidth inside the ISP is definitely cheaper than anything.
- bronco21016 7y agoBut my point still stands. That was a design decision. There is nothing technically stopping them from changing it if they felt they could ease the strain on their downstream bandwidth by using more localized caching and even P2P schemes. In the end it just further highlights that downstream bandwidth is cheap if they don’t mind sending 20 copies of Stranger Things in 4K down the pipe to a single node covering a neighborhood. So why the data caps?
