ABSTRACT:
In a frame buffer monitoring method and device, information concerning a received frame is extracted, and a monitoring frame added to a start of the frame is written in a FIFO buffer. When the monitoring frame is read from the FIFO buffer, expectation information is generated from the information concerning the frame added to the start of the monitoring frame read, the expectation information is compared with the information concerning the frame included in the frame within the monitoring frame read, and whether or not the expectation information is consistent with the information concerning the frame is determined. As a result of the comparison, when it is determined that the expectation information is not consistent with the information concerning the frame, e.g. bits of an FCS within the frame which is determined to be inconsistent are inverted to be transmitted to a subsequent stage as a discarded frame or the frame is discarded. Also, a write destination address and a read source address for the FIFO buffer are initialized.
