1. A relay control circuit inside a switch device, the switch device having an address/port table and receiving a frame signal with a destination medium access control (DMAC) address, comprising:

  • an address scrambling circuit for changing a byte sequence of at least part of a plurality of bytes in the DMAC address of the frame signal to generate a scrambled DMAC address; and

    a transformation circuit coupled to the address scrambling circuit, for generating an index address according to the scrambled DMAC address including all bytes in the DMAC address, wherein the switch device sends out the frame signal according to the index address and the address/port table.
