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.

Network evaluating apparatus, network evaluating method, and program

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.
