Patent ID: 7818634

Claim:
A method for detecting consistency of link scrambling configurations of a receiving end and a transmitting end of a link, comprising: (1.1) counting an error ratio of received data packets during a first period; (1.2) determining whether the error ratio is above a first threshold; (1.3) if the error ratio is above the first threshold, determining that the link scrambling configurations of the transmitting end and the receiving end are inconsistent; and (1.4) if the error ratio is not above the first threshold, determining that the link scrambling configurations of the transmitting end and the receiving end are consistent; (2.1) if the error ratio is above the first threshold, counting an error ratio of data packets received during at least one second period; (2.2) determining whether the error ratio of the data packets in each of the second periods is above a second threshold; (2.3) if the error ratio of the data packets in each of the second periods is above the second threshold, determining that the link scrambling configurations of the transmitting end and the receiving end of the link are inconsistent; and (2.4) otherwise, returning to the process (1.1) of counting an error ratio of received data packets during the first period.
