Interface detection device and detection method employing the same

An interface detection device in electronic communication with a network tester, wherein the network tester provides network packets for the interface detection device, the interface detection device comprising:

• a plurality of local area network (LAN) interfaces, wherein two LAN interfaces are in electronic communication with the network tester, and the other LAN interfaces are externally and electrically interconnected in pairs to form corresponding wring paths;
• a signal control unit providing a group of default test data and a group of random test data for the LAN interfaces;
• and
• a path distribution unit electrically connected to the signal control unit, wherein the signal control unit controls the LAN interfaces to create verification data according to the random test data corresponding to the LAN interfaces, the signal control unit compares the verification data with the default test data and the random test data to automatically figure out wiring paths and corresponding wired transmission paths between any two of the LAN interfaces and allocate virtual transmission paths of the unconnected LAN interfaces, and the LAN interfaces are in electronic communication with each other through the wired and the virtual transmission paths to transfer the network packets.

A detection method for detecting and allocating wiring paths and transmission paths of a plurality of local area network (LAN) interfaces, the detection method comprising steps of:

• connecting two of the LAN interfaces to a network tester and connecting the other LAN interfaces in pairs;
• providing test data for the LAN interfaces to generate corresponding verification data, wherein the test data comprises a group of default test data and a group of random test data;
• and
• comparing the verification data with the test data to figure out corresponding wiring paths and transmission paths of test data and network packets.
