Abstract:
A data distributing system capable of distributing data to a destination using at least one distribution device having a lowest distribution cost associated therewith, comprising:a distribution information memory for storing distribution information including at least one available distribution device corresponding to each one of at least one destination;a distribution cost memory for storing distribution cost information corresponding to the at least one distribution device and distribution conditions;a selector for selecting the at least one distribution device having the lowest distribution cost for each one of the at least one destination from the at least one distribution device extracted from a destination information list stored in the distribution information memory corresponding to each one of the at least one destination when destination information is input, referring to the distribution cost information; anda distribution data output apparatus for distributing the data to the destination using the at least one distribution device selected by said selector;wherein upon receiving at least one distribution error message, said selector decides whether the data should be re-distributed using the same at least one distribution device, or whether the data should be re-distributed using another at least one distribution device available for the destination;said system further including:an analyzer for analyzing distribution error information upon receiving the at least one distribution error message from the destination and notifying said selector of a kind of error, wherein,when the kind of error is a temporary error, said selector supplies the distribution data output apparatus with destination information included in the distribution error information, and the distribution data output apparatus re-distributes the data using the same at least one distribution device, andwhen the kind of error is a fatal error, said selector selects another available at least one distribution device and supplies the distribution data output apparatus with destination information included in the other available at least one distribution device, and the distribution data output apparatus redistributes the data using the other available at least one distribution device.
