Conroy attacks BitTorrent: Ruins Australia online

The biggest criticism of the Rudd government’s plan to centrally censor the internet — apart from it being ill-defined, secretive, a potential human rights abuse, a great way to screw up broadband speeds, poorly planned, way behind schedule and tackling the problem of child sexual abuse in completely the wrong way — is that it won’t work. As Crikey has reported several times before. None of the filters tested in the first half of 2008 could touch peer-to-peer (P2P) networks like BitTorrent, which is where The Bad Stuff lives.

Just before Christmas, Senator Conroy tackled that last bit by declaring in a single sentence on his new blog: “Technology that filters peer-to-peer and BitTorrent traffic does exist and it is anticipated that the effectiveness of this will be tested in the live pilot trial.” If so, it’s news to the ISPs who signed up. But then they haven’t been given official notification yet, and the trials were meant to start before Christmas. Ahem.

BitTorrent is easy to understand, provided you skip the brain-imploding technical details. Instead of everyone downloading the same big media file from a central server, causing congestion, the file is split up into lots of little pieces. As soon as you’ve download one random piece, your computer becomes a server, swapping the pieces you already have for the missing pieces downloaded by other users — your peers. Automatically. Eventually everyone gets all of the pieces, with the work shared amongst all the participants.

BitTorrent is incredibly efficient. As we reported in March, Norway’s national broadcaster NRK used BitTorrent to distribute a full HD TV program to 80,000 people for just US$350 in bandwidth and storage charges.

Yesterday [Sunday], Crikey showed NRK project manager Eirik Solheim reports of Conroy’s plan.

“Wow!” he said. “A minister that is actively working to limit your country’s ability to distribute information and compete globally… If he plans to block BitTorrent traffic in general that would be a serious limitation to people’s ability to distribute content, creativity, ideas and information.”

Norway’s NHK groks The Torrent

While the music and movie companies rail against BitTorrent, Norwegian broadcaster NRK recently used the torrent’s capabilities to distribute a HD TV program to 80,000 people for just $350 total in storage and bandwidth.

[P]roject manager Eirik Solheim… estimated that the bandwidth bill would have been roughly $8000 had NRK chosen a more traditional delivery method…

All the HD video files were stored and delivered using Amazon’s S3 data service, which has optional bittorrent capabilities. NRK syndicated the .torrent episodes over an RSS feed, which allowed the program to work something like a podcast.

NRK recommends that people use Miro to subscribe: it’s the easiest way for folks to use BitTorrent and it fits their public-interest mission. The estimate that a high percentage of their downloaders (50% or more) are using Miro.

[…] Technically, the cost to the producer for distributing to a handful of viewers, say 300, is basically the same as doing so for 1,000,000 people. This is because after a point, distribution is handled by the viewers themselves; as the number of viewers rises, the work that NRK does stays constant.

I think I should be playing with Miro more…
