Fig. 1 shows a schematic diagram of an exemplary system architecture to which the technical solution of an embodiment of the present application may be applied.
As shown in fig. 1, the system architecture may include a terminal device (such as one or more of the smart phone 101, tablet 102, and portable computer 103 shown in fig. 1, but may also be other terminal devices with positioning functions), a network 104, and a server 105. The network 104 is the medium used to provide communication links between the terminal devices and the server 105. The network 104 may include various connection types, such as wired communication links, wireless communication links, and the like.
In one embodiment of the present application, communication between the server 105 and the terminal device may be performed, where the server 105 and the terminal device are respectively located 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, through a private network, a first communication packet forwarded by a target private network node in a target area, where the first communication packet includes header information and first communication data, where 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 determine, from the header information, an IP address of the target private network node in the private network, and send, through the private network, the second communication data to the terminal device based on the IP address of the target private network node in the private network.
It should be noted that, the cross-regional communication method provided in the embodiment of the present application may be executed by the server 105, and accordingly, the cross-regional communication device 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-regional communication scheme provided by the embodiments of the present application.
It should also be noted that the number of terminal devices, networks and servers in fig. 1 is merely illustrative, wherein the networks may include proprietary networks and public networks. According to the implementation requirement, the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, and can also be a cloud server for providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, basic cloud computing services such as big data and artificial intelligent platforms 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, etc., but is not limited thereto, and the present application is not limited thereto.
It should be explained that cloud computing (closed computing) as described above is a computing mode that distributes computing tasks over a resource pool formed by a large number of computers, enabling various application systems to acquire 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 in the sense of users, can be acquired at any time, can be used as required and can be expanded at any time. By establishing a cloud computing resource pool (cloud platform for short, generally called IaaS (Infrastructure AS A SERVICE) platform), multiple types of virtual resources are deployed in the resource pool for external clients to select for use.
The implementation details of the technical scheme of the embodiment of the application are described in detail below:
Fig. 2 shows a flow chart of a cross-region communication method according to an embodiment of the application, which can be performed by a device having a computing processing function and a communication function, such as the server 105 shown in fig. 1.
In addition, the cross-regional 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, and the cross-regional communication method includes at least steps 220 to 280, which are described in detail below:
In step 220, a first communication packet forwarded by a target private network node in a target area is acquired through the private network, where the first communication packet includes header information and first communication data, and the first communication data is sent by a target public network node in 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 distributed with a private IP address in the private network, and the private network only allows legal nodes to access, so that the safety, the high efficiency and the integrity of the transmission of communication data in the private network are ensured.
The public network is a network for all users, namely the Internet, 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 two public network nodes crossing regions communicate, for example, the two public network nodes crossing the country need to be forwarded through multiple layers of routes, so that communication data can be transferred.
In the present application, after the target public network node of the target area sends out in the communication process of the two inter-regional public network nodes, a private network node in a private network, that is, a target private network node, may be selected in the target area according to the proximity principle, and the first communication data is forwarded to the target private network node, where 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) of the local area 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 an IP address of the target private network node in the private network is recorded in the header information.
In step 240, second communication data is acquired, the second communication data being used to respond to the first communication data.
After the local public network node acquires the first communication data, the user responds to the first communication data, and sends out second communication data through the local public network node, so that 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 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 and obtained by learning the header information.
In step 280, the second communication data is sent to the target public network node over the private network based on the IP address of the target private network node in the private network.
The following will describe in detail the technical solution of the embodiment of the present application by taking a scenario of cross-country communication as an example with reference to fig. 3:
referring to fig. 3, an exemplary simulation of cross-zone communication is shown in accordance with one embodiment of the present application.
In the cross-country communication scenario 300, a proprietary network 302 and a public network 304 are included. The private network 302 includes a chinese private network node, a french private network node, a us private network node, and a japan 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 is understood that the french private network node and the french public network node both belong to the french area, and the chinese private network node and the chinese public network node both belong to the chinese 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).
In a specific example, the french public network node 301 sends out the first communication data S1, forwards the first communication message including the first communication data through the french private network node in the private network 302, the french public network node obtains the first communication data from the private network through the private network, learns to obtain the IP address information of the french private network node in the private network 302 according to the header information in the first communication message, and then 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 provided by the present application may 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 may be audio or video data, game data, or the like.
In one embodiment of the present application, the steps shown in fig. 4 may also be performed before the first communication packet forwarded by the target private network node of the target area is acquired through the private network in step 220.
Referring to fig. 4, a flow chart of a method according to one embodiment of the application is shown prior to acquiring a first communication packet forwarded by a target private network node of a target area over the private network. Specifically, steps 211 to 212 are included:
In step 211, the IP address of the target public network node in the public network is obtained.
In step 212, first packet communication data is sent to the target public network node through the public network based on the IP address of the target public network node in the public network, where the first packet communication data is first communication data sent to the target public network node historically.
In this embodiment, the first packet of communication data refers to the first historical piece of communication data sent by the local public network node to the target public network node as the data initiator. Since the IP address of the target private network node in the private network, which is close to the target public network node, is not known before the first communication data, which is historically sent to the target public network node, the first packet of communication data cannot be forwarded to the target public network node directly through the target private network node. Based on this, the first packet communication data may be sent to the target public network node over a public network.
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 a 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 in a subsequent process, the target private network node may send the first packet of 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 the first packet of communication data to the local public network node.
The following describes in detail the technical solution of the present embodiment, taking a scenario of cross-country communication as an example:
Referring to fig. 5, an exemplary simulation of cross-zone communication is shown in accordance with one embodiment of the present application.
In the cross-country communication scenario 500, the IP address of the french public network node in the public network may be obtained by the french public network node 303 according to the link of the french public network node 301 through DNS resolution, the french public network node 303 sends the first packet communication data S0 to the french public network node 301 through the public network 304 according to the IP address, for example, initiates a video call, and the french public network node 301 forwards the first communication data S1 for responding to the first packet communication data S0 to the french public network node 303 through the french private network node in the private network 302.
In another embodiment of the present application, the steps shown in fig. 6 may also be performed before the first communication packet forwarded by the target private network node of the target area is acquired through the private network in step 220.
Referring to fig. 6, a flow chart of a method of obtaining a first communication packet forwarded by a target private network node of a target area over the private network is shown in accordance with one embodiment of the present application. Specifically, the method comprises the steps 213 to 214:
In step 213, the IP address of the predefined private network node in the private network is obtained.
In step 214, first packet communication data is sent to the target public network node through the private network based on the IP address of the predefined private network node in the private network, the first packet communication data being the first communication data sent to the target public network node historically.
In this embodiment, if a private network node that is geographically close to a target public network node, that is, a predefined private network node that is predefined, is already 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, first packet communication data may be sent to the target public network node through the private network.
The following describes in detail the technical solution of the present embodiment, taking a scenario of cross-country communication as an example:
Referring to fig. 7, an exemplary simulation of cross-zone communication is shown in accordance with one embodiment of the present application.
In the cross-country communication scenario 700, the first communication data S00 may be sent out by the chinese public network node 303 to the french public network node 301 via the private network 302 according to an IP address of a predefined private network node (i.e. a target private network node) in the private network, whereupon the french public network node 301 forwards the first communication data S1 for responding to the first communication data S00 to the chinese public network node 303 via the french private network node in the private network 302.
In one embodiment of the present application, the local public network node of the local area may include at least one virtual child node, and the second communication data is sent by a target virtual child node in the local public network node.
In this embodiment, if the local public network node is a cloud server, at least one virtual server, that is, a virtual child node, may be in the cloud server. 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 a right to use the private network, an 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, where the target virtual sub-node has a right to use the private network when the virtual routing table is marked with an IP address of the target virtual sub-node in the public network.
The proprietary network only allows legal nodes to access because of the high efficiency and integrity for ensuring the security of the communication data transmission 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 arranged on 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 one 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 transmitting the second communication data to the target public network node over the private network is shown, according to one embodiment of the application. Specifically, steps 281 to 282 are included:
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, so as to obtain a second communication message.
In step 282, the second communication packet 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 packet to the 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 the destination IP address in the private network, and the second communication data is encapsulated by using a tunneling protocol, so as to obtain a second communication packet.
In the present application, the tunneling protocol may be a generic routing encapsulation (GRE (Generic Routing Encapsulation)) that encapsulates datagrams of certain network layer protocols, enabling these encapsulated datagrams to be transported in another network layer protocol (e.g., IP).
In this embodiment, step 282 of forwarding the second communication packet 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 of forwarding the second communication message to the target private network node over the private network according to one embodiment of the application is shown. Specifically, the method comprises the steps 2821 to 2822:
In step 2821, a local private network node corresponding to the local public network node is selected from the private network nodes of the private network according to the geographical proximity principle.
In step 2822, the second communication packet is forwarded to the local private network node, so that the local private network node forwards the second communication packet to the target private network node through the private network.
In the application, the local private network node corresponding to the local public network node is the local private network node similar to the local public network node in geographic distance.
The selection of the local private network node corresponding to the local public network node among the private network nodes of the private network may be implemented based on an Anycast technology, where the Anycast technology refers to that when a unicast address is allocated to more than one interface, a message to be sent is routed by the network to a "closest" target interface measured by a routing protocol, that is, the local private network node in this embodiment.
The Anycast allows the source node to send datagrams to one of a set of destination nodes, which is transparent to the source node, and the routing system selects the "nearest" node to provide service to the source node, thereby providing better service to the source node to a certain extent and also reducing 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, thereby ensuring that the communication data can be transmitted to the private network node nearest 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 belonging to the same area as the target public network node, and the second communication data for responding to the first 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, so that the communication data of the cross-regional communication are all transmitted on the private network, and the quality of the cross-regional communication is no longer affected by the low stability defect of the public network, thereby improving the stability of the cross-regional communication. And inter-regional communication is performed through the private network, so that a non-optimal delay communication path in the public network is avoided, and the time efficiency of the inter-regional communication is accelerated.
