Claim Text:
1. An Ethernet-compatible data transmission method for a new network, wherein the new network is a network with a centralized control function, a terminal is connected to the new network via an Ethernet, and the method comprises: accessing, by an Ethernet protocol translation gateway, the new network, and obtaining an MAC address of a terminal bound to the Ethernet protocol translation gateway from a node server with a centralized control function; receiving, by the Ethernet protocol translation gateway, a data packet transmitted from the new network, adding an MAC address of the Ethernet protocol translation gateway and an MAC address of a target terminal into the data packet, and then transmitting the data packet to the Ethernet; and receiving, by the Ethernet protocol translation gateway, a data packet transmitted from the Ethernet, removing the MAC address of the Ethernet protocol translation gateway and an MAC address of a source terminal from the data packet, and then transmitting the data packet to the new network, wherein both the target terminal and the source terminal comply with new network protocols; wherein accessing, by the Ethernet protocol translation gateway, the new network comprises: issuing, by a node server with a centralized control function in the new network, a query packet; receiving, by the Ethernet protocol translation gateway, the query packet after being powered on and initialized, and returning a reply packet containing a serial number of the Ethernet protocol translation gateway; looking up, by the node server, information of the Ethernet protocol translation gateway corresponding to the serial number in a registration information table, wherein the information of the Ethernet protocol translation gateway includes the MAC address of the Ethernet protocol translation gateway and the MAC address of the terminal bound to the Ethernet protocol translation gateway; transmitting, by the node server, a network access command to the Ethernet protocol translation gateway, wherein the network access command contains an address of the Ethernet protocol translation gateway in the new network and the MAC address of the Ethernet protocol translation gateway; and returning, by the Ethernet protocol translation gateway, a reply after receiving the network access command, and accessing, by the Ethernet protocol translation gateway, the new network; and after accessing, by the Ethernet protocol translation gateway, the new network, the method further comprises: notifying, by the node server, the Ethernet protocol translation gateway of the MAC address of the terminal bound to the Ethernet protocol translation gateway, wherein binding relation between the MAC address of the terminal and the Ethernet protocol translation gateway is preset in the node server when the terminal and the Ethernet protocol translation gateway are sold.
