Content-based encoding in a multiple routing path communications system

摘要

A method includes partitioning a data file into first priority data and second priority data. The method further includes determining first error coding dispersal storage function parameters for the first priority data based on first transmission reliability level and second error coding dispersal storage function parameters for the second priority data based on second transmission reliability level. The method further includes dispersed error encoding the first priority data using the first error coding dispersal storage function parameters to produce first plurality of sets of encoded data slices and dispersed error encoding the second priority data using the second error coding dispersal storage function parameters to produce second plurality of sets of encoded data slices. The method further includes selecting one or more routing paths from a plurality of candidate routing paths and transmitting the first plurality of sets of encoded data slices via the one or more routing paths.
