Patent ID: 8654675

Claim:
An interface detection device in electronic communication with a network tester to receive network packets, the interface detection device comprising: a plurality of local area network (LAN) interfaces, two of the LAN interfaces in electronic communication with the network tester, and other LAN interfaces externally and electrically connected in pairs; a signal control unit providing preset test data for the LAN interfaces and controlling the LAN interfaces to generate verification data according to a determination of whether corresponding LAN interfaces are connected together; and a path distribution unit electrically connected to the signal control unit, wherein the signal control unit compares the verification data with the test data, and controls the path distribution unit to automatically figure out wired transmission paths between any two of the LAN interfaces and allocate internal virtual transmission paths of unconnected LAN interfaces, and the LAN interfaces are in electronic communication with each other through internal and external transmission paths to transfer the network packets; wherein the signal control unit assigns and provides a group of default test data and a group of random test data that represent link capabilities of the interface detection device, the default test data is predetermined according to transmission rate of the network packets, the signal control unit controls the LAN interfaces to exchange the random test data to generate the verification data corresponding to the LAN interfaces; and wherein the group of random test data, the group of default test data, and the verification data all include eight binary numbers, and two of the group of random test data are different from each other, top five binary numbers of the random test data cannot be all 0, and the eight binary numbers of the random test data are different from the eight binary numbers of the default test data.
