As shown in fig. 7, when the first subsystem and the second subsystem send network requests to the same target network, a communication port of the main system to the target network is established based on the network response, and a first virtual port for the first subsystem and a second virtual port for the second subsystem are established. As shown in fig. 8, when the first subsystem and the second subsystem send network requests to different target networks, based on the network responses, communication ports of the two different main systems to the target networks are established, and a first virtual port for the first subsystem and a second virtual port for the second subsystem are established.
