'Godfather' of DOCSIS Looks Beyond DOCSIS 3.0
Still faces serious upstream, contstant bit rate limitations...
Rouzbeh Yassini, considered by many to be the "godfather" of the DOCSIS cable specification, says that while DOCSIS 3.0 is a great advancement, there's plenty of work to be done. For his keynote address at the Light Reading DOCSIS 3.0 conference in Denver
, Yassini addressed the fact that the specification still has upstream limitations. "Good job, but no cigar yet," he says. "Even 35 Mbps upstream is still not enough," says Yassini, even though channel bonding should eventually address this. Yassini also noted that DOCSIS 3.0 100Mbps downstream speeds are peaks, not constants -- in an industry where constant bit rates are increasingly important for HD.

Yes, I agree with that. What happens when you have a backup that's a little over 100GB. THAT would be truely painful, wouldn't it?
What if you had two computers...
Over 200GB! No thanks! Makes me glad I have an external here to do more frequent backups vs what I'd do online with 200GB worth of stuff to back up.
I'd do twice a month on my external if I had that much, while online, I'd do it once maybe every 2-3 months.
Also, you have to be aware of Comcast's combo 250GB cap when doing something that large.
We have file server with 1.8TB data, 3 computers all approaching 800GB on their drives, plus a few external's all needing to be backed up.
Off-site back ups with a typical residential cable/dsl connection is all but impossible, not enough upload as well as silly caps.
as others have said, upload is becoming increasingly needed just to do routine things.. we ourselves do a lot of video and audio here and hate waiting hours to upload a simple 15 min HD vid clip.

said by jadebangle:Please give an example where 2 or 3mbit upload isn't adequate for a residential connection.
Its always 10/1, 20/2, 30/3 massive on the download side, pathetic on the upload side
Yes, you may be uploading all those 8megapixel images to flickr or posting your kids 2 hour birthday party video to youtube. All those things can benefit from faster speeds and would be nice, but 2 or 3mbits is adequate.
Don't get me wrong, faster is always nicer, but the overwhelming majority of users barely use their upstream now.
