    • An adaptive coding storage system that uses adaptive erasure resilient code (ERC) which changes the number of fragments used for encoding according to the size of the file 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 embodiment small, dynamic data files are diverted to the more reliable peers or even a server, while large and static files are stored utilizing the storage capacity of the unreliable peers. Also, for balanced contribution and benefit, a peer should host the same amount of content as it stored in 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.
    • 一种自适应编码存储系统,其使用自适应擦除弹性码(ERC),其根据所分配文件的大小改变用于编码的片段的数量。 自适应ERC可以大大提高P2P存储的效率和可靠性。 还可以实现用于P2P存储应用的多个过程。 在一个实施例中,小的动态数据文件被转移到更可靠的对等体或甚至服务器,而使用不可靠对等体的存储容量来存储大而静态的文件。 此外,为了平衡贡献和收益,对等体应该承载与存储在P2P网络中相同数量的内容。 因此,不可靠的对等体被允许分配更少的数据,并且允许更可靠的对等体分发更多的数据。 而且,分配较小的文件分配成本较高,分配较大的文件分配成本较低。
