Before describing the technical solution provided by the embodiments of the present application, in order to facilitate understanding of the embodiments of the present application, the present application first specifically describes a problem existing in the prior art:
as described above, the inventors of the present application have found that communication between heterogeneous virtual networks needs to be achieved by means of an underley network in the prior art. When communication is carried out between virtual networks, the virtual network at one end needs to firstly strip off the head encapsulation of the virtual network to make the virtual network appear in the underly network, and when the virtual network reaches the other end through the underly network, the virtual network at the other end needs to be encapsulated again, so that the forwarding efficiency of the communication mode is low and the CPU resource consumption is high. In addition, when the header package of the virtual network is stripped off to make the virtual network appear in the underly network, the workload of the virtual network becomes a part of the underly network, so that the service layer and the network layer are mixed up, and the complexity of the underly network is greatly increased.
In order to solve the problems in the prior art, embodiments of the present application provide a communication system, a method, an apparatus, and a storage medium of a heterogeneous virtual network.

Illustratively, as shown in connection with fig. 1, when the first device control system 120 is to create the first target device 122, or the second device control system 140 is to create the second target device 143, the first device control system 120 or the second device control system 140 may send a request for applying an IP address to the control module 110, and the control module 110 may assign an IP address for creating the first target device 122 to the first device control system 120 according to the request of the first device control system 120, or assign an IP address for creating the second target device 143 to the second device control system according to the request of the second device control system 140. For example, one VPC may use a network of 192.168.2.0/24, the control module 110 may assign 192.168.2.3 IP addresses to the first target devices 122 and 192.168.2.4 IP addresses to the second target devices 143, where each first target device 122 and each second target device 143 have their own independent IP address.
