The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The channel machine in the existing private network communication system only supports the post-routing transmission mode. In the post-routing transmission mode, the channel machine transmits an Internet Protocol (IP) address of the device in the local area network to the core network, so as to realize data transmission between the device and the core network.
However, in a distributed network, data transmission is achieved between core networks through wide area network IP addresses. The existing equipment developed based on the channel machine in the post-routing transmission mode can realize data transmission through the local area network IP under the corresponding core network, and perform corresponding services, but under the distributed network, the data sent by other core networks cannot find the corresponding equipment according to the local area network IP address, and transmit the service data to the equipment. Therefore, in the existing technical scheme, under the distributed network, the problem that the data sent by the core network cannot be transmitted to the device end exists.
In order to solve the above problem, embodiments of the present application provide a data transmission method and apparatus, which have solved a problem in the prior art that data sent by a core network in a distributed network cannot be transmitted to a device side. The invention conception of the application is as follows: the forwarding mapping relation between the wide area network IP address information and the port address information and between the local area network IP address information and the port address information is added in the channel machine, so that the data received by the channel machine can be forwarded to the corresponding equipment, and the data transmission between the core network and the equipment under the distributed network is realized.

When the terminal device 012 performs the corresponding service, first, the corresponding function on the forwarding device 011 is called through a service Software Development Kit (SDK), and sends a request that the data transmission mode is the Network Address Translation (NAT) mode to the forwarding device 011, the forwarding device 011 sets the forwarding mode as the NAT mode after receiving the request, then, the terminal device 012 sends the IP address information and the port address information allocated according to the service type of the service data to the forwarding device 011, and after the forwarding device 011 receives the IP address information and the port address information, the local area network IP address information and the port address information of the terminal device 012 are replaced with the wide area network IP address information and the port address information of the forwarding device 011, and the mapping relation is stored, and finally, the forwarding device 011 transmits the wide area network IP and the port address information to the network device. Further, the service data sent by the network device 010 may find the forwarding device 011 through the wide area network IP address of the forwarding device 011 and send the service data to the forwarding device 011, and the forwarding device 011 finds the corresponding terminal device 012 according to the stored mapping relationship and forwards the service data to the terminal device 012, thereby implementing data transmission between the network device 010 and the terminal device 012 in a distributed network.
