METHOD, APPARATUS AND SYSTEM FOR ACQUIRING MEDIA ACCESS CONTROL ADDRESS

摘要

The invention discloses a method for acquiring a media access control (MAC) address. The method comprises: receiving a first address resolution protocol (ARP) broadcast message transmitted by a first terminal; and acquiring an address of an ARP server, modifying a destination address of the first ARP broadcast message into the address of the ARP server and transmitting the address to the ARP server so as to make the ARP server acquire a MAC address of a second terminal according to the modified message and transmit an ARP response message to the first terminal, wherein the ARP response message comprises the MAC address of the second terminal. With the embodiments of the invention, the address of the ARP server is acquired, and then the destination address of the first ARP broadcast message is modified into the address of the ARP server; the ARP broadcast message becomes a unicast message which is only transmitted to the ARP server; and the network bandwidth occupied by the ARP broadcast is reduced; and because the modified ARP broadcast message is only transmitted to the ARP server and other receiving terminals cannot receive the message, the occupancy of other receiving terminal central processing unit (CPU) resources in the network is avoided, and the resource utilization rate of the system and the communication efficiency of each terminal are improved.
