Method for increasing amount of a data packet

A method of configuring at least a switch for duplicating a data packet and enabling the switch to output a plural duplicated data packets at a speed and volume qualifying for testing a device-under-test, the method comprising the steps of:

• (a) dividing the switch into a first segment and a second segment, each having a plurality of ports, wherein one port of the first segment is assigned as an input port and one port of the second segment is assigned as an output port;
• (b) assigning a plurality of port virtual IDs (PVIDs) respectively to each port of the first segment so as to establish a first virtual LAN (VLAN), and assigning a plurality of port virtual IDs (PVIDs) respectively to each port of the second segment so as to establish a second virtual LAN (VLAN) while enabling the input port to transmit the data packet to the other ports in the first segment basing on the assigned PVIDs of first VLAN, and the output port to be capable of receiving the data packets from the other ports in the second segment basing on the assigned PVIDs of second VLAN;
• (c) corresponding all the ports other than the input port in the first segment to all the ports other than the output port in the second segment;
• (d) inputting a set of data to the input port, wherein the data packet is transmitted to all the ports other than the input port in the first segment, and then each port of the first segment transmits the received data packet to the corresponding port of the second segment, and thus the output port of the second segment received a plural duplications of the data packet respectively transmitted from each port of the second segment other than the output port;
• and
• (e) outputting the plural received data packets at the output port.
