Abstract:
A full duplex/half duplex mismatch is detected by a full duplex/half duplex mismatch detecting apparatus connected through a network to a host. The loss rate of the transmission of a check messages is compared according to a sequential transmission pattern and the loss rate of the transmission of the check message according to divided transmission patterns by the full duplex/half duplex mismatch detecting apparatus, and if the loss rate of the transmission of the check messages according to the sequential transmission pattern is the larger, a full duplex/half duplex mismatch is determined to be present on the network path.
