Report Says Schools Need 100Mbps Per 1,000 Users
alphadogg writes "American schools need mega-broadband networks — and they need them soon, a new report says. Specifically, U.S. educational institutions will need networks that deliver broadband performance of 100Mbps for every 1,000 students and staff members in time for the 2014-15 school year. That's the conclusion reached by the State Educational Technology Directors Association. Why the need for speed? For one thing, more and more schools are using online textbooks and collaboration tools, said Christine Fox, director of educational leadership and research at SETDA. Broadband access must be 'ubiquitous' and 'robust,' she said, adding that schools should think of broadband as a 'necessary utility,' not as an add-on. The report, called 'The Broadband Imperative,' further suggests that schools should upgrade their networks to support speeds of 1Gbps per 1,000 users in five years."
All the better to torrent with, my dear!

I suppose that local caching of something as relatively static as a textbook is out of the question? My dead-tree edition books were often cached for 5-20 years. Really, how frequently does arithmetic change from year to year? Literature? Science and "Social Studies" I buy as being a little more dynamic, but still within a year?
100Mbps for textbooks
It's a new DRM system.

From TFA:
Trust me. They won't even consider that possibility. It's only a problem when it affects them.
And that is the core problem.
Do they have any idea what the price is for that kind of Internet connection?
I'd be looking at huge caching servers first.
Speaking as a Network admin at a major university, the amount of bandwidth-per-user really depends on the levels of control the school is allowed (or willing) to apply to the user's Network usage.
For example, in our residences, students are told they have unfiltered access to the Internet, as in, they are allowed to use any software they wish. The only stated restrictions are overall bandwidth related on a per-day basis. Behind the scenes, a we use packet shaping hardware to limit the total amount of per-user bandwidth usable for such things as P2P or VoIP (to prevent super-nodes) but otherwise leave it alone. In this model, 100Mbps per 1000 students is inadequate, but only just barely. We currently have it at approximately 120Mbps per 1000 students.
Under tighter control circumstances, where P2P is disabled and/or other controls, caps, and so on are enacted, you can likely get away with less bandwidth. Other networks we distribute have such tighter controls, and allow us to dial the number down further to around 70Mbps per 1000 students (without any web censorship).
I submitted my homework, but the intertubes are full and until they are cleared you won't receive my homework.
My wife is a kindergarten teacher. In order for her students to access the content she is required to teach them they must first logon to the machines in the computer lab. (I'll avoid a diatribe on the woes of the poor password practices they are forced to teach these minions...) It can often take 1/3 of her classes computer lab time just to log on; granted much of this wasted time is due to the fact that kindergarteners can't remember their passwords but, an equal amount is also caused by the lag caused when the network is flooded with their logon requests (she has less than 20 students).
Once they've accomplished the herculean task of getting the little minions logged onto the lab computers the real fun begins. Most of the content is only available online from the publishers of the text books the school uses. Adding insult to injury the publishers sites are difficult to navigate often requiring the students to manually type in long cryptic URLs that would make torrent users eyes bleed. While much of the content is colorful, animated and has pleasing sound effects try and imagine what accessing this content is like on a network that can't handle a few dozen simultaneous logons.
While I'm a fan of using online resources, the schools (as directed by their boards of education, county governments etc.) seem to have truly put the digital cart before the horse in the mad dash to move toward education online. Also without competent, which of course often means properly paid, tech support (she was once told by a tech the printer wouldn't print because she was using a japanese USB cable) adding bandwidth is pointless.
Do they have any idea what the price is for that kind of Internet connection?
When you get up to buying a gig, not as much /Mbps as the smaller allotments. But you are right, that would be a stretch for most institutions, mainly because their routers/firewalls/content-filtering/etc is not sized for the number of connections/pps that such a pipe would support. They'd be looking at a full re-buy and reprovisioning of their entire gateway path.
Someone had to do it.
Coming soon in Ask Slashdot: "I was assigned to set up a school network (about 100Mbps for 1000 users)..."
I'd be looking at huge caching servers first.
Christine Fox: "What's that?"
Someone mod parent up. Their requirements clearly indicate the need to repeatedly access same content. Which means that you could cut your bandwidth usage by 999 times when that content, accessed by 1,000 students, is cached locally when the first student accesses it. Can you imagine the cost savings of such a responsible solution instead of knee-jerk response resulting in head-on capacity accommodation?
Bow before me, for I am root.
and define the bottom 2%
in NYC a teacher that teaches in one of the most elite schools in the city was ranked one of the worst. reason her kids didn't improve from last year. they are already the best in the city but because they didn't improve she's a bad teacher
or what if all your kids never do homework and never study because their parents don't care?
Because, The Cloud... It's always good!
Today's content providers seem to jump through every possible hoop to defeat caching.
You would think that a video provider would use some indirect URL to first log the access attempt and then point to a static location where the actual video is provided, and that can be cached locally, but no...
In a new deployment, including a caching proxy probably is a waste.
E.g. our existing proxy now has a byte-% hit ratio of 11%, falling all the time.
My local school district has several Verizon FiOS 115 Mb/sec connections for the district of 4,000 K-12 students. It isn't that expensive, but it is essentially residential-grade service.
They pay about $200/connection per month, probably $1K/month - much cheaper than the subsidized business class service the district had before, and much faster.
Our in school wire network is Fast Ethernet to the desktop, Gigabit backbone.
It was non-trivial to get this service at a public school, due to rate regulations.

Sorry.. but this statement is just B.S. Apple IIs and TRaSh-80s were the gateway for hundreds of future computer users and programmers. Students learned TONS on them, though maybe not was initially intended.
I agree with the point made often around here is that there is magical thinking when it comes to educational computer use. Today you need good guides. Computers in the classroom also mean something totally different when most homes have smart phones and PCs. However, you have to be careful... Apple IIs in schools enable a new era... it's not fair to say that they didn't. However, today kids already have already had the exposure to computers that the AppleII gave my generation so you need to take it to the next step and get under the hood.
Thank HTML5 for the death of caching as much as the advertising.
It is all apps now. And in schools they KNOW they are all incompetent boobs so they want nothing that requires skilled labor to maintain. So outsourcing is the word. Everything. Gradebooks, attendance, cafeteria manegement, email of course, Courseware, scheduling and calendaring, yearbooks. If it isn't being delivered from the cloud now it is because they are still fighting over which vendor they want to write a check to. (read as the bidding is still fierce over who will kick back more.. ok, I'm a cynic) That pattern means they need LOTS of bandwidth now and will need an ever growing amount going forward into an HD Video for everything future.
And the vendors love it. It will of course drive lots of sales to schools themselves but when the kids can't do their homework without a constant high bandwidth connection it drives the 'Internet is a 'Right'' meme that leads to even more billions and billions of sweet sweet government money that will only be available to the politically connected.

Yeah, whoosh.
Breakfast served all day!
> why would the school not upload to you tube?
You obviously know nothing about the way schools work. There is an entire industry devoted to reinventing every wheel for educational use. Some of it makes some sense, schools have a lot of mandates for privacy and so on, but most of it is simply because. YouTube would be right out, a contract with an edu specific video hosting site would be required, and it would of course require a hefty annual contract with each school system. Each school would have to get a customized portal with the school logo, colors and such or it is a no sale. Access controls are a must. You can't put a picture that includes a student on a school's public facing website without moving a lot of paper for clearances.... meanwhile the local paper's website has the same photo from the game up that day and the kids themselves post everything onto their facebook pages in realtime. And it simply must be this way, the idea that it could be different could never occur. If nothing else, schools simply wouldn't be able to handle the concept of a vendor that doesn't charge.
