I'm only on the 2 down 300 up right now, but it would be nice. Also, SBC in my area is going to offer "Firewire DSL" which is going to have 5m down and 500 up. Comcast however is still at the bottom of the barrel. The only benefit they have around here is reliable connections. ]]> http://www.dslreports.com/forum/remark,8835362 Fri, 19 Dec 2003 15:20:00 EDT Re: Awesome http://www.dslreports.com/forum/remark,8526775 anon : Windows Media Encoder(realtime video feeds) uses TCP. ShoutCast(usually audio, does work with video, just a pain to set up) uses TCP. Almost all on-demand streaming is accomplished through http over TCP, simply by downloading the file as it's playing. UDP is used mostly for online games and netconferencing(which can include video) and old RealVideo streams. But we all know that RealVideo is a fading format, don't we? Also, I would like to point out that depending on packet size, the bandwidth used by ACKs varies. Obviously, bigger packets means fewer ACKs, but more retransmission if a packet gets lost. Usually the ACKs for downloading at 1.5mbps amount to a total of about 5KBps(or 40kbps). It's not a major factor on your connection, however enough to cause your downloads to seriosuly slow down by a saturated upstream. nklb's estimates are way out of proportion. A 3mbps/128kbps connection would work just fine for *just downloading*. But don't try to upload at the same time -- it will kill your download speed.

But back to the original topic, the real question is when connections like Starpower(RCN)'s 3.5mbps/768kbps with as much of that upload available as you could possibly want per month(trust me, I know people who have tested this...^.~) will become standard.]]> http://www.dslreports.com/forum/remark,8526775 Mon, 17 Nov 2003 11:53:48 EDT Re: Awesome http://www.dslreports.com/forum/remark,8494088 anon : But in streaming video, UDP is used instead of TCP, so there aren't Acks.]]> http://www.dslreports.com/forum/remark,8494088 Thu, 13 Nov 2003 12:03:23 EDT Re: Awesome http://www.dslreports.com/forum/remark,8491650 indy0365 : I have no promlems watching videos 3/128]]> http://www.dslreports.com/forum/remark,8491650 Thu, 13 Nov 2003 01:59:19 EDT Re: Awesome http://www.dslreports.com/forum/remark,8491632 SexyGirl0 : i hope comcast raises theirs too! ]]> http://www.dslreports.com/forum/remark,8491632 Thu, 13 Nov 2003 01:54:32 EDT Re: Awesome http://www.dslreports.com/forum/remark,8491563 KnightDreams : I have no problem watching videos online, and I download at 2.7mbps and upload at 187kbps.

Not to throw a wrench but what does upload have to do with "watching" videos.
It has plenty to do. In TCP/IP, a packet's receipt has to be acknowledged, so by downloading full on at 1.5mbps, you would need about 128kbps up just for the return packets. Now that speeds are 3mbps down, you would need even more upload.
