Re: Let's talk Upstream Bandwidth

@Elochai I doubt that you will see any movement on the upload speeds for the very near future. That will require DOCSIS 3.1 upload to be enabled.  Currently I think there are two, maybe three tests ongoing, possibly less.  Rogers has not indicated when we can expect this to happen, but, its probably two to three firmware versions down the road.  Even then, when it is implemented, who knows what upload rates Rogers will allow.  It will be interesting to see how this works out.  At the end of the day, DOCSIS 3.1 upstream can support 1 to 2 Gb/s upload, Full Duplex DOCSIS 3.1 can support 10 Gb/s download and upload.  The low rate upload is probably what the Rogers engineering staff are working on at the present time, Full Duplex spec was only completed last year, so, I don't expect to see that rolled out anywhere for another year or two, maybe more. 

 

At the present time, I think that you'll only see significantly higher data rates over cable in test labs.  There might be the odd European system running higher data rates, but, I haven't been keeping an eye on this particular issue so I'm not sure of the progress on the other side of the pond.

That’s really to bad, you think they would at least give you some real speeds on higher packages. 20 Mbps upload paired with a 500 Mbps download is just poor. The Gigibit is even worst at 30 Mbps, but I downgraded to the 500 Mbps package because the Gigibit plan wasn’t worth the price as most servers only pushed out about 600 Mbps that I connect too. However I run servers in Montreal, Dallas, and New York and when uploading files to a servers that can do Gigibit, you’d like to know you have a good connection speed when your paying for it that can do speeds in the 100 Mbps range at least.

Re: Let's talk Upstream Bandwidth

I was wondering if there is any particular reason why upload speeds with rogers are capped at around 30Mbps while Download speeds can get all the way to Gigabit. Is there any practical reason why this asymmetry  is so pronounced? I know that Bell Gigabit, for instance, has symmetric upload/download speeds where available.

 

 

Thanks in advance for helping me quench my curiosity!

Yes, regarding upload on rogers network it is still on DOCSIS 3.0, which limit upload to 200 Mbps for entire neighborhood or for everyone who is sharing same cable modem termination system. In comparison downstream is running on 3.1 which allow 10 Gbps bandwidth for entire neighborhood, although they are theoretical max rates for DOCIS specs, actual bandwidth available is determined by how much is available at CMTS/MDU.

 

Rogers still has to implement DOCIS 3.1 in upstream direction, which will raise max upload between 1-2 Gbps, then Rogers need to add support for 3.1 Full Duplex which will allow 10 Gpbs in both direction.

 

Why Rogers hasn't done yet that is million dollar question?

@H0W1K2

 

Rogers has confirmed that they're trying to to roll out D3.1 on the upstream next year in 2019.

As for Full Duplex it will take a bit longer.

Oh, that is great news and long overdue for them. If I am not mistaken, I heard it will be mid year of 2019, though I was not sure about it.

Re: Let's talk Upstream Bandwidth

There is no specific date yet for 2019, for now it's a sometime in 2019 tentative.
