Abstract: A transmission control device includes a delaying section and a transmitting section. When an application program calls a connect function, the delaying section delays transmission of a synchronize packet in response to the calling of the connect function. Upon calling of a transmit function by the application program while the transmission of the synchronise packet is being delayed, the transmitting section transmits the synchronise packet including transmission target data in response to the calling of the transmit function.

Abstract: Disclosed herein is a network evaluating apparatus including: an acquisition section acquiring a plurality of packets each of which includes an identification value indicating an order in accordance with which data is transmitted from a transmission source, the plurality of packets being received one by one; and an evaluation section, in a case where the identification value included in a first packet as any one of the plurality of received packets indicates that the first packet is transmitted before a second packet received before the first packet, increasing an evaluation value indicating instability of a transmission and reception path.

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.
