Just spent 3 weeks on dial-up, surprised at how

But 2 weeks back got back on cable & compared to when I had this same service 4 years ago, it is stunningly fast now. The day after getting it activated, I downloaded some large files from IBM (approx 4 gb). I was concurrently downloading CD images & at one point the aggregate download speed hit 620 kilobytes/second. At the same time I was following a discussion on a cable forum about just how fast cable could be run. One person who seemed to know what he was talking about said he has 2 cable accounts using 2 cable modems plugged into the one wall outlet. Each modem ran on a different 'channel' on the cable & he used 2 particular Intel gigabyte nics that allowed him to do load balancing using Windows, between the modems whilst performing a single download. He claimed he was reaching 2 gigabits/sec (presumably from the ISP's own server). My how times change (& networking speed up) Doug #2 corrected quoted speeds _____________________________________ From another place at another time, but every bit applicable to today: "Blinding ignorance does mislead us.

I don't know if this is the same for v2.0 or not. I'd hedge that it is more. But NOT at 1000 Megabit per sec range. -- [link\|mailto:greg@gregfolkert.net\|greg], [link\|http://www.iwethey.org/ed_curry\|REMEMBER ED CURRY!] @ *i_wethey* Give a man a match, he'll be warm for a minute.

But I can see I am saying megabytes when I should be saying megabits. My modem is a Motorola 5100 DOCSYS 2.0 SurfBorad. This link says that DOCSIS 2.0 can reach 30.72Mbs per channel [link\|http://www.ietf.org/proceedings/01dec/slides/ipcdn-3/sld003.htm\|http://www.ietf.org/...pcdn-3/sld003.htm] Cheers Doug _____________________________________ From another place at another time, but every bit applicable to today: "Blinding ignorance does mislead us.
