INFORMATION PROCESSING DEVICE, PORT DETECTION DEVICE, INFORMATION PROCESSING METHOD, AND PORT DETECTION METHOD

摘要

There is provided an information processing device including a bubble packet transmission unit (12) for transmitting a bubble packet via a communication processing device (2), a detection packet transmission unit (16) for transmitting a detection packet used for detecting a position of a bubble packet transmission port via the communication processing device (2) in such a manner that the detection packet transmission port which is a port of the communication processing device (2) through which a detection packet has passed is the same as or different from the bubble packet transmission port according to the type of the communication processing device (2), and a bubble packet transmission port detection unit (21) for detecting the position of the bubble packet transmission port according to the position of the detection packet transmission port. With this configuration, when a bubble packet for leaving a transmission history in the communication processing device is transmitted, it is possible to accurately detect the position of the bubble packet transmission port which a port of the communication processing device through which the bubble packet has passed.
