    摘要： An improved system for accessing data within a distributed data storage network (“DDSN”) is disclosed. In a system implementing the disclosed invention, traffic is routed to individual slice servers within the DDSN in accordance with objective criteria as well as user-defined policies. In accordance with one aspect of the disclosed invention, when a data segment is written to a DDSN, the segment is divided into multiple data slices, which are simultaneously transmitted to different slice servers. In accordance with another aspect of the disclosed invention, when a data segment is read from a DDSN, a list of slice servers, each containing a data slice that could be used to reconstruct the requested data segment, is assembled, and sorted in accordance with a preference rating assigned to each of the slice servers. Sufficient data slices to reconstruct the data segment are then read in accordance with the preference ranking of the slice servers.

    摘要： A computer includes a data transform algorithm, a data dispersal algorithm, and a network port. The data transform algorithm performs a data transformation on a data block to produce a transformed data block. The data dispersal algorithm performs a data dispersal function on the transformed data block to produce a plurality of data slices, wherein each of the plurality of data slices includes less than all data contained in the transformed data block. The network port is operable to transmit a plurality of write commands to a plurality of slice servers, wherein each of the plurality of write commands includes a corresponding one of the plurality of data slices. The network port is further operable to receive verification of storage of at least some of the plurality of data slices from at least some of the plurality of slice servers.

    摘要： A method for reading data from a dispersed data storage network that includes a plurality of slice servers. The method begins by accessing a list of slice servers of the plurality of slice servers, wherein each slice server on the list stores at least one data slice associated with a data segment of the data. The method continues by transmitting read requests to at least some of the slice servers on the list. The method continues by receiving a data slice from a slice server on the list. The method continues by determining whether a threshold number of data slices has been received. The method continues, when the threshold number of data slices has been received, assembling the data segment from at least the threshold number of data slices.
