PURPOSE:To reduce the load of a network by reducing the transfer frequency of updated data between the resources control computers. CONSTITUTION:The resources information data base included in a fixed disk 4 stores the network resources information added with the updating date data for each resources. Meanwhile all resources information updated within a prescribed time are turned into blocks together with the updating date data and stored in a mail transmission queue 10. This processing is repeated at each prescribed time. Then the updated resources information turned into blocks and stored in the queue 10 are sent to another resources control computer which has the same data base as the resources information data base. Meanwhile the updated resources information turned into blocks and received from another resources control computer is once stored in an updated data receiving register 9 and divided into the data for each resources. Then the corresponding resources information stored in the data base is compared with the updating date data. When the former information is later than the latter data, the resources information stored in the resources information data base is updated.
