free bandwidth

[geek]

Coral CDN is simple and free service. No more bandwidth costs for your MP3, Video and Picture content. Just append ".nyud.net:8090" to the hostname of any URL, and your request for that URL is handled by Coral.

Awesome. It looks like a great help to the ppl here who are running out of bandwidth.
But I still dont get the idea. I mean, how does it work. Doesnt it have to get the page from the server eventually. Its like a bit of a proxy.
Oh boy, i am confused, but in the meanwhile, thanx geek for that site. Esp. good for ppl of HM ;)

[undacuvabruva]

what does append mean?
just add the .nyud.net:8090 to the end of the URL?
I did that w/ my site but it didn't work

[shwaza]

Well in sounds to me like the files are stored on your computer somehwere, or maybe you upload them to their server, and then if you add that to your url, and type in /file.extension it will come up, i didn't really look into it, because i'll just put my files on my server :P

WEll, looks like a sortof a intermediate proxy sortof thing to me. WHen you visit a particular url, for eg, I went to http://www.atwebhosting.com/forum , with the appending, I went to the forums, but I was logged in as a guest. Hence, my guess is that the system acts like a proxy for the 1st try, ie, when u first go to that site.
But once you go to the site, the page is stored on the Coral CDN server. Hence, the effective bandwidth usage is less comparatively.

Thats my best bet on how it must be working.

Exactly. Try http://www.whatismyip.com.nyud.net:8090

Not your IP is it? It's actiong just like a proxy: Fetching the page for you, and displaying it to you.

Whoa yeah, that's way off lol. Kind of a strange service to be giving out, and who'd really want to have .nyud.net:8090 at the end of their file names lol. Also, why wouldn't they just use port 80 :P seems like an extra 5 charactors they don't need, unless the actual server is seperate from the thing...

[Phreak]

Why would anyone give out free bandwidth? Isn't there a catch?

[paquitodorito]

there has to be a catch somewhere. do they gather info from your pages?

[choir]

May be they are doing some statistic collection?

[Silver]

Um.... there's one thing that still bothers me. If they say that they are giving bandwidth for ur site, then it must be that the pages that are visted are stored locally on cdn server. Otherwise, the bandwidth for u would be the same.
Storing of webpages that ever1 can see is ok. But I am just a bit about passwords. I mean, who knows, they might log the password fields from certain sites which are visited from the proxy.
But the " for MP3, Video and Picture content" is a bit strange. If this is why they are donatin the bandwidth, then I doubt password collection being happening.
Also, I have another doubt-> For most mp3s, vids and pics, they are copyrighted. Storing of such stuff locally, and broadcasting it from there is as such illegal. They can work like just a proxy, but then how the heck is ur bandwidth saved.

Whao, wait a sec, I read sumthing-
It achieves this through a novel indexing abstraction we introduce called a distributed sloppy hash table (DSHT), and it creates self-organizing clusters of nodes that fetch information from each other to avoid communicating with more distant or heavily-loaded servers.

btw, look at this http://www.scs.cs.nyu.edu/coral/pubs/
Reading... Sloppy Hashing and Self-Organizing Clusters ....

But I still dont get the darn use of just "givin" away bandwidth and clusters of networked computers away for free, atleast when there are supposed to be commercial cdns as well.

Well that's a thing that is seriously good.

But Silver does raise a good point about the security, i mean seriously you don't want your locked pages shown for everyone to see.

But the notion of getting extra bandwidth is great especially if it is a really active site and has a lot of media.

[wildfire]

Unless they store your files and database on their server, there is no way that they can access your site without using your bandwidth. This couldn't possibly work. If they copied your entire site, it would be out of date when you opened it, something just isn't right about this.

hmm very wierd i dont like the look of it allso putting that tag behind an address for me = dns error

...or maybe there's some very board people with too much free time on their hands ?

but seriously, i tried going to the www.nyud.net and I got this:

PlanetLab is a global overlay network for developing and accessing new network services. Our goal is to grow to 1000 geographically distributed nodes, connected by a diverse collection of links. Toward this end, we are putting PlanetLab nodes into edge sites, co-location and routing centers, and homes (i.e., at the end of DSL lines and cable modems). Since the beginning of 2003, more than 450 research projects at top academic institutions and industrial research labs have used PlanetLab to experiment with such diverse topics as distributed storage, network mapping, peer-to-peer systems, distributed hash tables, and distributed query processing.

Researchers using the PlanetLab network are bound by an Acceptable Usage Policy which forbids experiment that cause complaints from remote network administrators (e.g., performs systematic port scans).

Interesting, but adding that to the end of a URL doesn't seem to work for me. Even the whatismyip one didn't ? Strange

i just found this @ digg.com, i've never used it, i have 75gigs/mo of bandwith, don't really need it. I just thought i would post it here for peoople to check into, I know theres a lot of talk about hosting files and streaing music/videos due to bandwidth costs.
