Stewart Alsop On Broadband
Stewart Alsop On Broadband.
Stewart Alsop's current column in Fortune details his back and forth with broadband access to the home. Although he started as a fan of DSL, he's moving over to the cable camp.
I have to say I'm not convinced and in fact, think cable creates a bad dynamic for the future development of the Internet. I'm just not a fan of assymetric broadband access. Cable tends to have significantly more downstream (to the home) bandwidth than upstream and performance for most day-to-day applications (i.e., web surfing) certainly is better on cable. But this assymetry creates a dynamic that discourages the development of applications that serve content back to the web -- in fact, most cable ISPs prevent their customers from operating web servers on their home networks.
By limiting the back channel, broadband over cable has the potential to push the Internet more and more towards becoming a one way medium. Such a thing happened 80 years ago with radio. While it's unlikely that history will repeat itself, we need to push for symmetric broadband networks. Only that way can we keep building the Internet into a medium in which every consumer can also be a producer. [VentureBlog]
