Claim:
A data transfer method between a plurality of data transfer apparatuses, comprising the steps of: establishing peers between said plurality of data transfer apparatuses to store the established peers in a transfer route configuration data table as transfer route configuration data in each of said plurality of data transfer apparatuses; and transferring a reception data to specific ones of said plurality of data transfer apparatuses based on said transfer route configuration data in each of said plurality of data transfer apparatuses, wherein said establishing step includes the steps of issuing an establishment request from one of said plurality of data transfer apparatuses to the other data transfer apparatuses for peers to be established; confirming whether a loop is produced, based on said transfer route configuration data in said transfer route configuration data table in each of the other data transfer apparatuses; and establishing said peer with said one data transfer apparatus when it is determined that the loop is not produced.
