Re: a growing trend? it would seem from what I read, cable ISP's seem to be softcapping and all this other crap, more often then DSL providers are doing it. Is this a sign that DSL is a better system, or maybe DSL is cheaper to setup/upgrade/run. DSL is a little slower then cable in most areas, but it makes up for it in the overall bandwidth you can use.
Maybe Cable Internet will just become obscelete, or maybe it'll just get better if something better comes around to threaten it. | | |

Is this a sign that DSL is a better system, or maybe DSL is cheaper to setup/upgrade/run. DSL is a little slower then cable in most areas, but it makes up for it in the overall bandwidth you can use. I would say that from a network-infrastructure administration and upgrade POV, DSL is superior.
Cable has a lot of inherent limitations based on the original design of their cable plant, which is based on the idea of local neighborhood distribution "nodes". That worked out well, and was more economical for one-way signal distribution like video, but it definately creates a bottleneck "in the field" for the users of that node when capacity reaches the limits of utilization. I'm not a cable guru, but I'm assuming that they would have to physically install another node or something, and then split the load between them.
DSL, on the other hand, is a straight shot between customer and the line-card at the CO or RT. There's plenty of headroom left in that link, assuming that the line can physically handle it, based on distance. Some can go to 8-9Mbit/s, or higher with newer technology. Sure, at the CO end, the bandwidth between all of the users is shared, so both DSL and cable are shared at some point. But with DSL you could just upgrade the upstream "trunk" line and replace the router(s), all in one location, instead of a bunch of neighborhood nodes. | |
