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, when the first device control system 120 has a communication requirement, a communication request is sent to the control module 110, and the control module 110 invokes the virtual router configuration module 130 to configure the routing information into the routing table of the first virtual router 121 according to the communication requirement of the first device control system 120; the first virtual router 121 encapsulates a tunnel header of the overlay network, encapsulates the traffic of the first target device 122 to be transmitted in a tunnel of the overlay network, and sends the encapsulated traffic of the first target device 122 to the first host 123 according to the configured routing table; the first host 123 receives the encapsulated traffic of the first target device 122, and forwards the traffic to the second host 141 of the second device control system 140 through the tunnel of the overlay network; the second host 141 receives the encapsulated traffic of the first target device 122 and sends it to the second virtual router 142; the second virtual router 142 may decapsulate the tunnel header of the overlay network to obtain the traffic of the first target device 122 encapsulated in the tunnel of the overlay network, and send the traffic of the first target device 122 after decapsulation to the second target device 143.

Similarly, when the second device control system 140 has a communication requirement, a communication request is sent to the control module 110, and the control module 110 invokes the virtual router configuration module 130 to configure the routing information into the routing table of the second virtual router 142 according to the communication requirement of the second device control system 140; the second virtual router 142 encapsulates the tunnel header of the overlay network, encapsulates the traffic of the second target device 143 that needs to be transmitted in the tunnel of the overlay network, and sends the encapsulated traffic of the second target device 143 to the second host 141 according to the configured routing table; the second host 141 receives the encapsulated traffic of the second target device 143, and forwards the traffic to the first host 123 of the first device control system 120 through the tunnel of the overlay network; the first host 123 receives the encapsulated traffic of the second target device 143 and sends the traffic to the first virtual router 121; the first virtual router 121 may decapsulate the tunnel header of the overlay network to obtain the traffic of the second target device 143 encapsulated in the tunnel of the overlay network, and send the traffic of the second target device 143 after decapsulation to the first target device 122.

According to the communication system of the heterogeneous virtual network, the first virtual router of the first equipment control system packages the flow of the first target equipment in the tunnel of the overlay network, the first host machine directly sends the packaged flow of the first target equipment to the second host machine of the second equipment control system through the tunnel of the overlay network, and the second virtual router of the second equipment control system unpacks the tunnel head of the overlay network, so that the communication of the first equipment control system and the second equipment control system on a unified network plane is achieved. Because the first equipment control system and the second equipment control system both work on the overlay network layer, and the flow of the first target equipment is also hidden in the tunnel of the overlay network and invisible to the underlay network, the communication between heterogeneous virtual networks can be directly realized through the overlay network without resorting to the underlay network, the communication efficiency between heterogeneous virtual networks is improved, and the resource consumption of a CPU (Central processing Unit) is reduced.

In some embodiments, the virtual router configuration module 130 is further configured to create a first virtual route forwarding 124 in the first virtual router 121 and a second virtual route forwarding 144 in the second virtual router 142 according to the call of the control module 110.

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.

As shown in fig. 1, the first virtual router 121 encapsulates a tunnel header of the overlay network, encapsulates traffic of the first target device 122 that needs to be transmitted in a tunnel of the overlay network, and sends the encapsulated traffic of the first target device 122 to the first host 123 according to the configured routing table.

S203, the first host sends the packaged flow of the first target device to a second host of the second device control system.

As shown in connection with fig. 1, after receiving the encapsulated traffic of the first target device 122, the first host 123 forwards the traffic to the second host 141 of the second device control system 140 through the tunnel of the overlay network.

According to the communication method of the heterogeneous virtual network, the first virtual router of the first equipment control system is used for packaging the flow of the first target equipment in the tunnel of the overlay network, the first host machine is used for directly sending the packaged flow of the first target equipment to the second host machine of the second equipment control system through the tunnel of the overlay network, and the second virtual router of the second equipment control system is used for unpacking the tunnel head of the overlay network, so that the communication of the first equipment control system and the second equipment control system in a unified network plane is achieved. Because the first equipment control system and the second equipment control system both work on the overlay network layer, and the flow of the first target equipment is also hidden in the tunnel of the overlay network and invisible to the underlay network, the communication between heterogeneous virtual networks can be directly realized through the overlay network without resorting to the underlay network, the communication efficiency between heterogeneous virtual networks is improved, and the resource consumption of a CPU (Central processing Unit) is reduced.
