Abstract: A load balancer includes: a request queue that stores a request scheduled to be transmitted to a server; a transmission unit that transmits a request read from the request queue to the server capable of processing the request; a reception unit that receives a completion message indicating that processing of the request is completed; and a completion list that stores the completion message, and the transmission unit discards a request for which the completion message is stored in the completion list without transmitting the request to the server, and transmits, to the server, a request for which the completion message is not stored in the completion list and stores the request again in the request queue.

Abstract: A number management unit (11) of a number management system (1) generates a transaction to be managed in a blockchain based on number portability information obtained by receiving a number update request, generates a block obtained by aggregating multiple transactions, approves a suggested block by confirming normality of the block, and stores the block by connecting the block to a blockchain in a number database (13). If a reset of the block in the number database (13) is suggested, the number management unit (11) transmits, to multiple number management apparatuses (10), a reset suggestion block including, as a transaction, a reset suggestion, which is information indicating a suggestion for a reset, and if the reset suggestion block is approved, the number management unit (11) discards the blockchain in the number database (13).
