Abstract: A method, apparatus and system for transmitting data. The system includes: the load balance gate wall translating a virtual MAC address of the virtual server in a destination address of a data packet from a client to a real MAC address of the real server according to a pre-configured address mapping relationship between a real server and a virtual server; the load balance gate wall sending a modified data packet to the virtual switch; the virtual switch determining a data packet flowing into the real server after receiving the data packet from the load balance gate wall, then translating a virtual IP and a virtual port of the virtual server in the destination address in the determined data packet to a real IP and a real port of the real server; and the virtual switch sending the modified data packet to the real server.
