Why We Don't Need Gigabit Networks (Yet)
AmyVernon writes "Most computers today can't support gigabit connections and current Wi-Fi networks can't offer those speeds either. The first trial of Sonic.Net's gigabit network was a speed test on a generic laptop that showed off 420 Mbps down; the laptop couldn't handle a full gig. Plus, few applications need those speeds. It's hard to justify such a huge investment in a network that will have few subscribers and few applications that need it. Of course, that can change, and then these networks will be vital. This story has a good analysis of where things stand and what has to change."
Gigabit networks are important when working with almost any kind of file copy. I am not sure the last time someone tried to backup even just 100GB of data (Think backups) over a 100 megabit network. Copies like that can take for ever a fully saturate 100 megabit network and slow down traffic for everyone. While copies over gigabit rarely use the entire pipe its good to know that there is still bandwidth left over for other tasks.
How DARE you say we don't need faster networks! This article should be purged from the interwebs and timothy should be strung up by his gonads for even considering posting it!
The reason this post is stupid is that infrastructure is long term. When you go to the trouble of sending out a crew to dig up and put fiber in the ground your putting in an infrastructure asset that should have a 15-30 year lifespan. The fact that can average machine can't saturate it today means we're being forward thinking.
is not for one computer to saturate it, but for 10 machines to get decent throughput simultaneously.
As the island of our knowledge grows, so does the shore of our ignorance.
When you wake up to the obvious facts of 1999, let me know, and I'll give you an invite to the 21st century. Cuz I'm k3vvL and rollz like dat.

The streaming model can die the death it deserves at that point.
Streaming is still the only model I can see for live events such as news talk shows, sports, scripted sports (e.g. WWE PPV), concerts, and the like where viewing begins before the whole video has even been recorded.
No, but the argument is "this cheap and shitty laptop could only manage to use half of the gig connection, so therefore no one needs gig speeds for the home".
An argument that is easily destroyed by saying "ok, do you live alone? Do you have more than one person using a computer at the same time?"
It's not just servers. I share a house with 4 other people and we can all watch HD streaming video on the connection we have, just. If the bandwidth goes up a little, or people start using off-site backup more frequently I can see a market for a consumer-level gig connection. I know you can already get them in some other European countries (here in the UK, the best you can get on a consumer budget is 100Mb (soon to be 200Mb) from Virgin cable).
One shitty laptop might choke on a gig connection, but three or four computers will happily share it.
My organization is on the verge of needing to move our equipment to 10gig soon, because the 1gig network is starting to become a serious bottleneck...
Um, probably not. He's rolling out fiber in my town of 7000. But it's also his business to know whether it's really going to be saturated so they can do the right network on the backend. Sonic.net is a pretty kick-ass ISP. They instituted outbound SMTP blocking. But they noticed I'm running my own SMTP server and sent me an email saying they weren't blocking SMTP to/from me, but I could enable/disable it just by visiting my member account page. Also, they just rolled out free fax numbers (gateway to PDF/email) and outbound faxing for everyone.

I read the article as a laptop being too slow because of its drive not handling data that quickly.
That neatly bypasses a very real need for high speed low latency remote connections where disk speed is irrelevant -- remote desktops, remote apps and VPN, often in combinations. And in combination with other things that suck bandwidth too.
There's more to bandwidth than file transfers.
