Super-seeding

Source: Wikipedia, the free encyclopedia.

In

BitTorrent communications protocol that helps downloaders become uploaders more quickly, but it introduces the danger of total seeding failure if there is only one downloader.[citation needed
]

The algorithm applies when there is only one seed in the swarm. By permitting each downloader to download only specific parts of the files listed in a torrent, it allows peers to start seeding more quickly.[1] Peers attached to a seed with super-seeding enabled therefore distribute pieces of the torrent file much more readily before they have completed the download themselves.[2][3]

In 2003, BitTornado became the first BitTorrent client to implement the algorithm.[citation needed]

Effects

Testing by one group found that super seeding can help save an upload ratio of around 20%. It works best when the upload speed of the seed is greater than that of individual peers.[4]

Super seeding transfers stall when there is only one downloading client. The seeders will not send more data until a second client receives the data. To avoid this, rTorrent continues to offer more pieces to the peers without waiting for confirmation, until it is uploading at its configured capacity.[5]
