Communication state estimating apparatus, a recording medium for storing the communication state estimation method and a communication state estimating program

Improving the accuracy of identifying the state of the network provides a communication state determining apparatus capable. Communication state estimating device according to one embodiment of the present invention, depending on the given communication parameters, the communication device determines the occurrence of a communication error in the communication with the communication destination apparatus, a setting means for providing the communication parameters, communication sends said communication instruction to the communication device that performs the communication in response to receiving the instruction, and detection means for detecting the occurrence of the determined communication error in the communication according to the instruction, the communication parameter and the based on the occurrence of a communication error, and an estimation means for the communication device to estimate whether it is possible the communication.
