[0002] In Internet communication scenarios, such as Internet communication scenarios between two communication devices across regions, communication is usually carried out through a public network. The communication data traffic between the two communication devices is all on the public network line. When there are problems such as communication export failures of the communication equipment, international submarine cable failures, network congestion, etc., the network quality cannot be effectively guaranteed, and it is impossible to control whether the path on the public network is the optimal path, and the delay quality is also uncontrollable.

It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those shown or described.

[0038] Figure 1 A schematic diagram of an exemplary system architecture to which the technical solution of the embodiments of the present application can be applied is shown.

[0039] like Figure 1 As shown, the system architecture may include terminal devices (such as Figure 1 The present invention relates to a mobile phone 101, a tablet computer 102, a portable computer 103, or other terminal devices with positioning functions, a network 104, and a server 105. The network 104 is used to provide a medium for a communication link between the terminal device and the server 105. The network 104 may include various connection types, such as a wired communication link, a wireless communication link, and the like.

[0040] In one embodiment of the present application, it may be communication between a server 105 and a terminal device, wherein the server 105 and the terminal device are in different regions, for example, in different countries, and the server 105 and the terminal device may be regarded as two nodes in a public network, and both the server 105 and the terminal device have IP addresses in the public network. Specifically, the server 105 may obtain a first communication message forwarded by a target private network node in a target area through a private network, wherein the first communication message includes header information and first communication data, and the first communication data is sent by a terminal device in the target area, and then the server 105 may obtain second communication data for responding to the first communication data, and at the same time determine the IP address of the target private network node in the private network from the header information, and based on the IP address of the target private network node in the private network, send the second communication data to the terminal device through the private network.

[0041] It should be noted that the cross-regional communication method provided in the embodiment of the present application can be executed by the server 105, and accordingly, the cross-regional communication device is generally set in the server 105. However, in other embodiments of the present application, the terminal device can also have similar functions as the server, so as to execute the cross-regional communication solution provided in the embodiment of the present application.

[0042] It should also be noted that Figure 1 The number of terminal devices, networks and servers in the description is only illustrative, wherein the network may include a proprietary network and a public network. According to the implementation requirements, the server may be an independent physical server, or a server cluster or distributed system consisting of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The terminal may be a smart phone, tablet computer, laptop computer, desktop computer, smart speaker, smart watch, etc., but is not limited thereto, and this application does not limit this.

[0043] It should be explained that cloud computing as described above is a computing model that distributes computing tasks on a resource pool composed of a large number of computers, so that various application systems can obtain computing power, storage space and information services as needed. The network that provides resources is called a "cloud". The resources in the "cloud" are infinitely expandable in the eyes of users, and can be obtained at any time, used on demand, and expanded at any time. By establishing a cloud computing resource pool (referred to as a cloud platform, generally referred to as an IaaS (Infrastructure as a Service) platform, various types of virtual resources are deployed in the resource pool for external customers to choose to use. The cloud computing resource pool mainly includes: computing devices (virtualized machines, including operating systems), storage devices, and network devices.

[0044] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0045] Figure 2 A flow chart of a cross-region communication method according to an embodiment of the present application is shown. The cross-region communication method can be executed by a device having a computing and processing function and a communication function, for example, Figure 1 Executed by the server 105 shown in .

[0046] In addition, the cross-region communication method can be implemented in a public network and a private network, wherein the public network includes a public network node and the private network includes a private network node. Figure 2 As shown, the cross-region communication method at least includes steps 220 to 280, which are described in detail as follows:

[0047] In step 220, a first communication message forwarded by a target private network node in a target area is obtained through the private network, wherein the first communication message includes header information and first communication data, and the first communication data is sent by a target public network node in the target area.

[0048] A private network is a type of private network that includes multiple private network nodes. Private network nodes are connected to each other through dedicated lines. Each private network node is assigned a private IP address in the private network. Only legal nodes are allowed to access the private network, which ensures the security, efficiency and integrity of communication data transmission in the private network.

[0049] The public network is a network for all users, namely the Internet. In the public network, there are a large number of public network nodes. Any two public network nodes can communicate through the public network. However, communication between two public network nodes across regions, such as communication between two public network nodes across countries, requires multiple layers of routing forwarding to achieve the transmission of communication data.

[0050] In the present application, during the communication between two cross-region public network nodes, after the target public network node in the target area sends out a signal, a private network node in a private network can be selected in the target area according to the proximity principle, that is, the target private network node, and the first communication data is forwarded to the target private network node. The target private network node forwards the first communication data to the local public network node in the local area through the private network (for example Figure 1 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 message including header information and the first communication data, wherein the header information records the IP address of the target private network node in the private network.

[0051] In step 240, second communication data is acquired, where the second communication data is used to respond to the first communication data.

[0052] After the local public network node obtains the first communication data, the user will respond to the first communication data and send the second communication data through the local public network node, so that the local public network node obtains the second communication data.

[0053] In step 260, the IP address of the target private network node in the private network is determined from the header information.

[0054] Since the IP address of the target private network node in the private network is recorded in the header information, the IP address of the target private network node in the private network can be determined by learning the header information.

[0055] In step 280, based on the IP address of the target private network node in the private network, the second communication data is sent to the target public network node through the private network.

[0056] The following will refer to Figure 3 , taking the scenario of cross-country communication as an example, the technical solution of the embodiment of the present application is described in detail:

[0057] See also Figure 3 , shows an example simulation diagram of cross-region communication according to an embodiment of the present application.

[0058] In the cross-country communication scenario 300, a private network 302 and a public network 304 are included. Among them, the private network 302 includes a Chinese private network node, a French private network node, a US 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 the French region, and the Chinese private network node and the Chinese public network node both belong to the Chinese region.

[0059] 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.

[0060] In the specific example, the French public network node 301 sends out the first communication data S1, which is forwarded through the French private network node in the private network 302. The French private network node then forwards the first communication message 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 based on the header information in the first communication message. Then, the Chinese public network node forwards the second communication data used to respond 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.

[0061] It should be noted that the communication data proposed in this application can be text data, for example, the target user sends a text message to the local user, and the local user responds to the target user with a text message. In addition, the communication data can also be audio or video data, or game data, etc.

[0062] In one embodiment of the present application, before obtaining the first communication message forwarded by the target private network node in the target area through the private network in step 220, the following may also be performed: Figure 4 Steps shown.

[0063] See also Figure 4 , shows a flow chart of a method before obtaining a first communication message forwarded by a target private network node in a target area through the private network according to an embodiment of the present application. Specifically comprising steps 211 to 212:

[0064] In step 211, the IP address of the target public network node in the public network is obtained.

[0065] In step 212, based on the IP address of the target public network node in the public network, a first packet of communication data is sent to the target public network node through the public network, where the first packet of communication data is the first communication data sent to the target public network node in history.

[0066] In this embodiment, the first packet of communication data refers to the first communication data in history sent to the target public network node by the local public network node as the data initiator. Because the IP address of the target private network node close to the target public network node in the private network is not known before the first communication data in history is sent to the target public network node, it is impossible to directly forward the first packet of communication data to the target public network node through the target private network node. Based on this, the first packet of communication data can be sent to the target public network node through the public network.

[0067] It should be noted that the target private network node close to the target public network node refers to the target private network node that is close to the target public network node in geographical distance.

[0068] 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 that is close to the target public network node itself can also be sent to the target public network node, so that in the subsequent process, the target private network node can 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, and further forward it to the local public network node.

[0069] The following continues to use the scenario of cross-country communication as an example to elaborate on the technical solution of this embodiment:

[0070] See also Figure 5 , shows an example simulation diagram of cross-region communication according to an embodiment of the present application.

[0071] In the cross-country communication scenario 500, the Chinese public network node 303 may obtain the IP address of the French public network node in the public network through DNS resolution based on the link of the French public network node 301. The Chinese public network node 303 sends the first packet of communication data S0 to the French public network node 301 through the public network 304 according to the IP address, for example, to initiate a video call. The French public network node 301 forwards the first communication data S1 used to respond to the first packet of communication data S0 to the Chinese public network node 303 through the French private network node in the private network 302.

[0072] In another embodiment of the present application, before obtaining the first communication message forwarded by the target private network node in the target area through the private network in step 220, the following may also be performed: Figure 6 Steps shown.

[0073] See also Figure 6 , shows a flow chart of a method before obtaining a first communication message forwarded by a target private network node in a target area through the private network according to an embodiment of the present application. Specifically comprising steps 213 to 214:

[0074] In step 213, an IP address of a predefined private network node in the private network is obtained.

[0075] In step 214, based on the IP address of the predefined private network node in the private network, the first packet of communication data is sent to the target public network node through the private network, and the first packet of communication data is the first communication data sent to the target public network node in history.

[0076] In this embodiment, if a private network node that is geographically close to the target public network node is known in advance, that is, a predefined private network node, the IP address of the predefined private network node in the private network can be directly obtained, and based on the IP address of the predefined private network node in the private network, the first packet of communication data is sent to the target public network node through the private network.

[0077] The following continues to use the scenario of cross-country communication as an example to elaborate on the technical solution of this embodiment:

[0078] See also Figure 7 , shows an example simulation diagram of cross-region communication according to an embodiment of the present application.

[0079] In the cross-country communication scenario 700, the Chinese public network node 303 may send the first packet of communication data S00 to the French public network node 301 through the private network 302 according to the IP address of the predefined private network node (i.e., the target private network node) in the private network. The French public network node 301 then forwards the first communication data S1 used to respond to the first packet of communication data S00 to the Chinese public network node 303 through the French private network node in the private network 302.

[0080] In one 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 by a target virtual sub-node in the local public network node.

[0081] In this embodiment, if the local public network node is a cloud server, the cloud server may have at least one virtual server, ie, a virtual sub-node. Each virtual sub-node in the local public network node has a corresponding IP address in the public network.

[0082] In this implementation, when the target virtual sub-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.

[0083] Furthermore, the local public network node may be provided with a virtual routing table, and when the IP address of the target virtual sub-node in the public network is marked in the virtual routing table, the target virtual sub-node has the authority to use the private network.

[0084] In order to ensure the security, efficiency and integrity of communication data transmission in the private network, the private network only allows legitimate nodes to access. Therefore, in this application, the IP address of the target virtual sub-node in the public network is recorded through the virtual routing table set by the local public network node, which can identify the legitimacy of the target virtual sub-node and further prove that the target virtual sub-node has the authority to use the private network.

[0085] In one embodiment of the present application, 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 as follows: Figure 8 Follow the steps shown.

[0086] See also Figure 8 , shows a detailed flow chart of sending the second communication data to the target public network node through the private network according to an embodiment of the present application. Specifically including steps 281 to 282:

[0087] 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 message.

[0088] In step 282, the second communication message is forwarded to the target private network node through the private network, so that the target private network node forwards the second communication data in the second communication message to the target public network node in the public network.

[0089] In step 281, the IP address of the target private network node in the private network may be used as the destination IP address in the private network, and the second communication data may be encapsulated through a tunnel protocol to obtain a second communication message.

[0090] In the present application, the tunneling protocol may be Generic Routing Encapsulation (GRE), which encapsulates datagrams of certain network layer protocols so that the encapsulated datagrams can be transmitted in another network layer protocol (such as IP).

[0091] In this embodiment, step 282 forwards the second communication message to the target private network node through the private network, which can be as follows: Fig. 9 The steps shown are performed:

[0092] See also Fig. 9 , shows a detailed flow chart of forwarding the second communication message to the target private network node through the private network according to an embodiment of the present application. Specifically including steps 2821 to 2822:

[0093] In step 2821, based on the principle of geographical proximity, a local private network node corresponding to the local public network node is selected from among the private network nodes.

[0094] In step 2822, the second communication message is forwarded to the local private network node, so that the local private network node forwards the second communication message to the target private network node through the private network.

[0095] In the present application, the local private network node corresponding to the local public network node is a local private network node that is close to the local public network node in geographical distance.

[0096] The selection of a local private network node corresponding to the local public network node among the private network nodes can be implemented based on Anycast technology. Anycast technology means that when a unicast address is assigned to more than one interface, the message to be sent is routed by the network to the "shortest" target interface measured by the routing protocol, which is the local private network node in this embodiment.

[0097] Anycast allows the source node to send datagrams to one of a group of target nodes, and this node is selected by the routing system and is transparent to the source node. At the same time, the routing system selects the "nearest" node to provide services for the source node, thereby providing better services to the source node and reducing the network load to a certain extent.
