Abstract: A delivery control apparatus, a delivery control method, and a delivery control program by which, even if listening port numbers are duplicate in multiple server processes, a packet that has the listening port numbers as its address can be properly delivered. A process management unit detects multiple running server processes that are generated by launch of mutually different server programs and that have the same listening port number. The process management unit performs control such that one server process of the detected multiple running server processes is put into an active state and the remaining server processes are put into a standby state. A reception unit receives a packet that has the listening port number as its address. A delivery control unit delivers the packet to the server process in the active state.
