A data transmission method compatible with an Ethernet, an Ethernet protocol translation gateway, a node server and an Ethernet-compatible communication system are provided to solve the problem of a new type of network. The new type of network is a network with centralized control function. The Ethernet protocol translation gateway can access the new type of network and obtain from a node server therein the media access control (MAC) address of the Ethernet protocol translation gateway and the MAC address of terminals bound to the Ethernet protocol translation gateway. Therefore, a data packet to be transmitted from the new type of network to an Ethernet can be forwarded to a target terminal in the Ethernet according to the MACs of the terminals, by means of the MAC of the Ethernet protocol translation gateway and the MAC of the target terminal being added to the packet. Likewise, for a data packet transmitted from the Ethernet to the new type of network, the packet can be forwarded to the new type of network according to the destination address of the new type of network in the packet by means of removing from the packet the MAC of the Ethernet protocol translation gateway and the MAC of the target terminal. Thereby, the convergence of the new type of network and the Ethernet is achieved.
