Fig. 1 shows a schematic diagram of an exemplary system architecture to which the technical solution of the embodiments of the present application can be applied.

As shown in fig. 1, the system architecture may include a terminal device (e.g., one or more of the smartphone 101, tablet 102, and portable computer 103 shown in fig. 1, but may be other terminal devices with positioning functionality), a network 104, and a server 105. The network 104 serves as a medium for providing communication links between terminal devices and the server 105. Network 104 may include various connection types, such as wired communication links, wireless communication links, and so forth.

In one embodiment of the present application, the communication between the server 105 and the terminal device may be performed, where the server 105 and the terminal device are respectively in different areas, for example, in different countries, and the server 105 and the terminal device may be regarded as two nodes in a public network, and the server 105 and the terminal device both have IP addresses in the public network. Specifically, the server 105 may obtain a first communication packet forwarded by a target private network node of a target area through a private network, where the first communication packet includes header information and first communication data, and the first communication data is sent by a terminal device of the target area, and then the server 105 may obtain second communication data for responding to the first communication data, determine an IP address of the target private network node in the private network from the header information, and send the second communication data to the terminal device through the private network based on the IP address of the target private network node in the private network.

It should be noted that the cross-region communication method provided in the embodiment of the present application may be executed by the server 105, and accordingly, the cross-region communication apparatus is generally disposed in the server 105. However, in other embodiments of the present application, the terminal device may also have a similar function as the server, so as to execute the cross-region communication scheme provided by the embodiments of the present application.

It should be further noted that the numbers of terminal devices, networks and servers in fig. 1 are merely illustrative, and the networks may include a proprietary network and a public network. According to implementation needs, the server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, a middleware service, a domain name service, a security service, a CDN, a big data and artificial intelligence platform, and the like. The terminal may be a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, and the like, but is not limited thereto, and the application is not limited thereto.

It should be explained that cloud computing (cloud computing) as described above is a computing model that distributes computing tasks over a large pool of computers, enabling various application systems to obtain computing power, storage space, and information services as needed. The network that provides the resources is referred to as the "cloud". Resources in the cloud can be infinitely expanded to users, and can be acquired at any time, used as required and expanded at any time. The cloud computing resource pool mainly comprises computing equipment (which is a virtualization machine and comprises an operating system), storage equipment and network equipment.

The implementation details of the technical solution of the embodiment of the present application are set forth in detail below:

fig. 2 illustrates a flow diagram of a cross-region communication method according to one embodiment of the present application, which may be performed by a device having a computing processing function and a communication function, such as server 105 shown in fig. 1.

In addition, the cross-region communication method may be implemented in a public network and a private network, where the public network includes a public network node, and the private network includes a private network node, as shown in fig. 2, the cross-region communication method at least includes steps 220 to 280, which are described in detail as follows:

in step 220, a first communication packet forwarded by a target private network node of a target area is obtained through the private network, where the first communication packet includes header information and first communication data, and the first communication data is sent by the target public network node of the target area.

The private network is a private network and comprises a plurality of private network nodes, wherein the private network nodes are connected with the private network nodes through private lines, each private network node is allocated with a private IP address in the private network, and the private network only allows legal nodes to access, so that the safety, the efficiency and the integrity of the transmission of communication data in the private network are ensured.

The public network is a network facing all users, i.e. the Internet, and in the public network, a large number of public network nodes are included, any two public network nodes can communicate through the public network, and communication between two cross-region public network nodes, for example, communication between two cross-country public network nodes, needs to be forwarded through multiple layers of routes to realize communication data transmission.

In the application, in the process of communication between two cross-regional public network nodes, after a target public network node in a target region is sent out, a private network node in a private network, that is, a target private network node, may be selected in the target region according to a principle of proximity, and the first communication data is forwarded to the target private network node, and the target private network node forwards the first communication data to a local public network node (for example, a server 105 shown in fig. 1) in a local region through the private network. It should be noted that, before the target private network node forwards the first communication data, the first communication data needs to be encapsulated to obtain a first communication packet including header information and the first communication data, where the header information records an IP address of the target private network node in the private network.

In step 240, second communication data is obtained, the second communication data being used in response to the first communication data.

After the local public network node acquires the first communication data, the user responds to the first communication data, second communication data is sent out through the local public network node, and the local public network node acquires the second communication data.

In step 260, the IP address of the target private network node in the private network is determined from the header information.

Since the header information records the IP address of the target private network node in the private network, the IP address of the target private network node in the private network can be determined and obtained by learning the header information.

In step 280, the second communication data is sent to the target public network node through the private network based on the IP address of the target private network node in the private network.

With reference to fig. 3, a cross-country communication scenario is taken as an example to describe in detail the technical solution of the embodiment of the present application:

referring to fig. 3, an exemplary simulation of cross-region communication is shown, according to one embodiment of the present application.

In the cross-country communication scenario 300, a private network 302 and a public network 304 are included. The private network 302 includes a chinese private network node, a french private network node, an american private network node, and a japanese private network node, and the public network 304 includes a french public network node 301 (i.e., a target user) and a chinese public network node 303 (i.e., a local user). It can be understood that the french private network node and the french public network node both belong to a french area, and the chinese private network node and the chinese public network node both belong to a french area.

In the present application, the china public network node 303 may be a cloud server, that is, a physical server where a cloud host is located in a cloud network vpc (virtual Private cloud) scenario.

In a specific example, the french public network node 301 sends out the first communication data S1, and forwards the first communication data through the french private network node in the private network 302, the french private network node forwards the first communication packet including the first communication data through the private network, the chinese public network node obtains the first communication data from the private network, and learns the IP address information of the french private network node in the private network 302 according to the header information in the first communication packet, and then the chinese public network node forwards the second communication data for responding to the first communication data to the french public network node through the french private network node in the private network based on the IP address information of the french private network node.

It should be noted that the communication data proposed in the present application may be text data, for example, a text message is sent by the target user to the local user, and the local user responds to the target user with a text message. Further, the communication data may be audio or video data, game data, or the like.

In an embodiment of the present application, before the step 220 of obtaining the first communication packet forwarded by the target private network node of the target area through the private network, the steps shown in fig. 4 may also be performed.

Referring to fig. 4, a flowchart of a method before acquiring, through the private network, a first communication packet forwarded by a target private network node of a target area is shown, according to an embodiment of the present application. Specifically, the method includes steps 211 to 212:

in step 211, the IP address of the target public network node in the public network is obtained.

In step 212, based on the IP address of the target public network node in the public network, sending a first packet of communication data to the target public network node through the public network, where the first packet of communication data is a first piece of communication data sent to the target public network node historically.

In this embodiment, the first packet of communication data refers to the historical first piece of communication data sent to the target public network node by using the local public network node as the data initiator. Before the first piece of historical communication data is sent to the target public network node, the IP address of the target private network node close to the target public network node in the private network is unknown, so that the first packet communication data cannot be directly forwarded to the target public network node through the target private network node. Based on this, the first packet communication data can be sent to the target public network node through the public network.

It should be noted that the target private network node close to the target public network node refers to a target private network node close to the target public network node in geographic distance.

In this embodiment, when the local public network node sends the first packet of communication data to the target public network node through the public network, the IP address of the local private network node in the private network, which is close to the target public network node itself, may also be sent to the target public network node, so that the target private network node may send the first communication data to the local private network node through the private network based on the IP address of the local private network node in the private network in a subsequent process, and further forward the first communication data to the local public network node.

The following explains the technical solution of the present embodiment in detail by taking a cross-country communication scenario as an example:

referring to fig. 5, an exemplary simulation of cross-region communication is shown, according to one embodiment of the present application.

In the cross-country communication scenario 500, the chinese public network node 303 may obtain an IP address of the french public network node in the public network through DNS resolution according to a link of the french public network node 301, the chinese public network node 303 sends the first packet communication data S0, for example, initiates a video call, to the french public network node 301 through the public network 304 according to the IP address, and the french public network node 301 accordingly forwards the first communication data S1 for responding to the first packet communication data S0 to the chinese public network node 303 through the french private network node in the private network 302.

In another embodiment of the present application, before the first communication packet forwarded by the target private network node of the target area is obtained through the private network in step 220, the steps shown in fig. 6 may also be performed.

Referring to fig. 6, a flowchart of a method before acquiring, through the private network, a first communication packet forwarded by a target private network node of a target area is shown, according to an embodiment of the present application. Specifically, the method comprises steps 213 to 214:

in step 213, the IP address of a predefined private network node in the private network is obtained.

In step 214, based on the IP address of the predefined private network node in the private network, sending a first packet of communication data to the target public network node through the private network, where the first packet of communication data is a first piece of communication data sent to the target public network node historically.

In this embodiment, if a private network node that is close to a target public network node in a geographical distance, that is, a predefined private network node, is known in advance, an IP address of the predefined private network node in the private network may be directly obtained, and based on the IP address of the predefined private network node in the private network, the first packet communication data is sent to the target public network node through the private network.

referring to fig. 7, an exemplary simulation of cross-region communication is shown, according to one embodiment of the present application.

In the cross-country communication scenario 700, the chinese public network node 303 may send out the first packet communication data S00 to the french public network node 301 through the proprietary network 302 according to the IP address of the predefined private network node (i.e., the target private network node) in the proprietary network, and the french public network node 301 accordingly forwards the first communication data S1 for responding to the first packet communication data S00 to the chinese public network node 303 through the french private network node in the proprietary network 302.

In an embodiment of the present application, the local public network node in the local area may include at least one virtual sub-node, and the second communication data is sent out by a target virtual sub-node in the local public network node.

In this embodiment, if the local public network node is a cloud server, there may be at least one virtual server, that is, a virtual child node, in the cloud server. And each virtual child node in the local public network node corresponds to an IP address in the public network.

In this implementation, when the target virtual child node has the authority to use the private network, the IP address of the target private network node in the private network is determined from the header information.

Further, the local public network node may be provided with a virtual routing table, and when the virtual routing table is marked with an IP address of the target virtual sub-node in the public network, the target virtual sub-node has a right to use the private network.

The proprietary network only allows legitimate nodes to access in order to guarantee the security, efficiency and integrity of the transmission of the communication data in the proprietary network. Therefore, in the application, the IP address of the target virtual sub-node in the public network is recorded through the virtual routing table set in the local public network node, so that the validity of the target virtual sub-node can be identified, and the target virtual sub-node is further proved to have the authority to use the private network.

In an embodiment of the present application, the step 280 of sending the second communication data to the target public network node through the private network based on the IP address of the target private network node in the private network may be performed according to the steps shown in fig. 8.

Referring to fig. 8, a detailed flow diagram of the sending of the second communication data to the target public network node over the private network is shown, according to one embodiment of the present application. Specifically, the method includes steps 281 to 282:

in step 281, the IP address of the target private network node in the private network is used as the destination IP address in the private network, and the second communication data is encapsulated to obtain a second communication packet.

In step 282, forwarding the second communication message to the target private network node over the private network, such that the target private network node forwards the second communication data in the second communication message to a target public network node in the public network.

In step 281, the IP address of the target private network node in the private network may be used as a destination IP address in the private network, and the second communication data is encapsulated through a tunneling protocol to obtain a second communication packet.

In the present application, the tunneling protocol may be generic Routing encapsulation (gre) which encapsulates datagrams of some network layer protocols such that they can be transported in another network layer protocol (e.g., IP).

In this embodiment, the step 282 of forwarding the second communication message to the target private network node through the private network may be performed according to the steps shown in fig. 9:

referring to fig. 9, a detailed flow diagram for forwarding the second communication message to the target private network node over the private network is shown, according to one embodiment of the present application. Specifically, the method comprises steps 2821 to 2822:

in step 2821, according to the geographical proximity principle, a local private network node corresponding to the local public network node is selected from the private network nodes of the private network.

In step 2822, forwarding the second communication message to the local private network node, such that the local private network node forwards the second communication message to the target private network node over the private network.

In this application, the local private network node corresponding to the local public network node is a local private network node close to the local public network node in geographic distance.

The selection of the local private network node corresponding to the local public network node in each private network node of the private network may be implemented based on an Anycast technique, where the Anycast technique refers to that when a unicast address is allocated to more than one interface, a packet to be sent is routed by a network to a "nearest-to-target interface" measured by a routing protocol, that is, the local private network node in this embodiment.

Anycast allows a source node to send datagrams to one of a set of destination nodes, which is selected by a routing system and transparent to the source node; meanwhile, the routing system selects the nearest node to provide service for the source node, thereby providing better service for the source node to a certain extent and reducing the network load.

In the application, the local public network node dynamically adjusts the communication path of the communication data according to the header information in the received communication message, and ensures that the communication data can also be transmitted to the private network node closest to the target public network node through the private network.

In the above embodiment of the present application, the first communication data sent by the target public network node is forwarded by the target private network node that belongs to the same area as the target public network node, and based on the IP address of the target private network node in the private network, the second communication data for responding to the first communication data is sent to the target public network node through the private network, so that the communication data of cross-area communication is transmitted on the private network, the quality of cross-area communication is not affected by the low stability defect of the public network, and the stability of cross-area communication is improved. And cross-region communication is carried out through a private network, so that a non-optimal delay communication path in a public network is avoided, and the time efficiency of cross-region communication is accelerated.

The following describes embodiments of the apparatus of the present application, which may be used to perform the cross-region communication method in the above-described embodiments of the present application. For details that are not disclosed in the embodiments of the apparatus of the present application, please refer to the embodiments of the cross-region communication method described above in the present application.
