Norwegian Broadcaster Evaluates BitTorrent Distribution Costs
FrostPaw writes "An experiment was conducted recently by Norwegian broadcasting company NRK involving the release of the series 'Nordkalotten 365' (a wildlife program) in a DRM free format using BitTorrent. One of the broadcasters has posted the approximate figures for the overall distribution costs, and discussed his reasons for doing so. Their estimated cost for using Amazon S3 to offer the files through HTTP/FTP/etc. come to approximately 41,000 NOK (about $8,000 US). However, when using the Amazon servers as the originating seed and utilizing BitTorrent, their total cost for distribution of the entire project, thanks to generous seeds, would amount to approximately 1,700 NOK. The post with the original figures is available only in Norwegian.
the definitive documentary about the Møøse!

Making other people do your work for free makes your own costs cheaper. Film at 11.
In other words, why is this news? It's something that has been obvious about BitTorrent since day 1: if you can get/make your users use their own upload bandwidth, you won't need as much of your own, and in a cost model that means your costs are lower. Did this really require a study?
It should be mentioned that NRK is owned by the Norwegian government, and that the programmes are not advertisement sponsored.
That's not Picasso, that's Kandinsky!
Amazon S3 has a unique feature. Lets say you got hugefile.mov to serve. User can click the .mov file directly to download via ordinary http/ftp or you simply add ?torrent to the URL and it creates/enables a torrent and start tracking it.
If everybody does this, home Internet connections need to be upgraded or we're going to get volume pricing again. Either way, end users are going to pay for this.
That's an interface problem - not a technical problem.
You could probably write a bittorrent client as a flash applet. You press the big, shiny download button that covers half of your screen, and the flash applet connects to peers and starts to download, all with a pretty progress bar. Even my grandfather could figure that out (one of my grandmas can't even use a mouse, the other is paranoid and believes that "They" are spying on her if she use a computer, so she got rid of it).
Or, you could let people download an exe file, that when clicked will automatically launch a simple bittorrent client that automatically opens the torrent file for Nordkalotten 365 and starts to download.
They have thousands of extra dollars that they no longer need to pay Amazon, that they could now throw at the problem. I'm sure they can figure something out.
If you're looking for the actual torrent files, episodes 1-8 can be found at the bottom of this post: http://nrkbeta.no/norwegian-broadcasting-nrk-makes-popular-series-available-drm-free-via-bittorrent/. I'm downloading episode 1 right now, and it has 73 seeds and 42 peers.
At some level this is redundant, but I'm going to state it in a slightly different way.
Of course distributing via BitTorrent is cheaper for the originator, nobody could possibly argue this. But I'd like to see a study on the TOTAL cost to society. In other words, yes it's cheaper for the originator, but there is no such thing as a free lunch. SOMEBODY is paying for all that bandwidth/etc. If you have bandwidth limits, perhaps you are paying for them to distribute their file. If you don't (as we in the US do not) then the telecommunications company is paying. Bandwidth does not materialize out of thin air. SOMEBODY pays. Further, BitTorrent is not exactly efficient. It uses a lot more requests/connections/etc to download or distribute via BT than it does via HTTP/FTP/etc.
The offsetting factor may be the more distributed load over the system, since there's no central point, really. I'm not sure how much this really helps though.
I guess my point is, the total cost to society of BitTorrent use may very well be higher than that for distributing by older methods.

What I'd really like to see is figures for the broadcaster and the hidden costs to the ISP for each of....
- Unicast
- Bittorrent
- Multicast
Multicast is so obviously the best solution all round for the, what, at least 50% of a national TV station's audience that watch predictable and consistent shows week after week. It would be pretty trivial for PCs to grab a multicast overnight.
By the way, the BBC really tried to do this right, but ISPs were too stupid to see that it was in their best interests to cooperate. This is my reading of the evidence - I accept corrections.
