FIELD: information technology.
SUBSTANCE: adaptive coding storage system which uses adaptive erasure resilient code (ERC) changes the number of fragments used for encoding according to the size of the distributed. Adaptive ERC may greatly improve the efficiency and reliability of P2P storage. A number of procedures for P2P storage applications may also be implemented. In one version small, dynamic data files are diverted to the more reliable peers or even a server, while large and static files are stored using the storage capacity of the unreliable peers. Also, for balanced contribution and benefit, a peer must host the same amount of content as it stored on the P2P network. As a result, unreliable peers are allowed to distribute less data, and more reliable peers are allowed to distribute more. Also, smaller files are assigned a higher distribution cost, and the larger files are assigned a lower distribution cost.
EFFECT: high efficiency and reliability of storing data on peer-to-peer networks.
