[0034] In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0035] With the rapid development of globalization, cross-border communication is becoming increasingly widespread. Currently, traditional cross-border communication solutions mainly establish network connections through the use of multi-protocol label switching (MPLS) and virtual private network (VPN) technologies throughout the entire process.

[0036] With the increasing demand for cross-border communication networks from enterprises, traditional cross-border communication solutions, such as establishing network connections through MPLS VPN technology, while providing stable and secure connections, suffer from high costs and poor flexibility. In recent years, the rise of SD-WAN and 5G slicing technologies has offered new solutions for cross-border communication. SD-WAN achieves flexible scheduling and cost optimization of network traffic through software-defined methods, while 5G slicing technology can control the priority of customer equipment access to the network by controlling the 5G QoS Identifier (5QI) level, thereby ensuring access quality.

[0037] As described above regarding cross-border communication technology solutions, in order to further meet the ever-expanding demand for cross-border communication, traditional cross-border communication technology solutions use larger-scale MPLS VPN networks to establish network connections. Establishing network connections for cross-border communication networks via MPLS VPN technology requires dedicated hardware and involves complex configurations. Due to the high deployment cost of MPLS VPN networks, existing cross-border communication technology solutions suffer from high deployment costs.

[0038] In view of this, the cross-border network data transmission method provided in this application establishes a network connection between the first device and the PoP device through MPLS VPN technology, and between the PoP device and the second device through SD-WAN technology. The hardware cost required for establishing a network connection through SD-WAN technology is lower than that required for establishing a network connection through MPLS VPN technology, and the network deployment process is simpler. Therefore, this application can reduce the link deployment cost of cross-border communication.

[0039] The technical solutions provided in this application can be applied to various communication systems, such as 5G New Radio (NR) communication systems, future evolution systems, or multiple communication convergence systems.

[0040] For example, Figure 1The diagram shows a schematic representation of a cross-border network system 10 provided in an embodiment of this application. The cross-border network system 10 may include at least one first device 101, at least one second device 102, and at least one point of presence (PoP) device 103. The first device 101 may be communicatively connected to the PoP device 103, and the second device 102 may be communicatively connected to the PoP device 103. Figure 1 Only one first device 101, one PoP device 102, and three second devices 102 are shown.

[0041] The first device 101 is located in the first region, and the second device 102 and the PoP device 103 are located in the second region.

[0043] The first device 101 is used to send service messages to the network access point (PoP) device 103 through Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) technology.

[0044] For example, the first device 101 and the second device 102 can be communication devices, which can be high-capacity devices with wireless communication capabilities (e.g., servers integrating a large number of boards), and can be deployed on land, including indoors or outdoors or in vehicles.

[0045] The aforementioned communication equipment can be a terminal that accesses the aforementioned cross-border network system and has wireless transceiver capabilities, or a chip or chip system that can be installed in the communication equipment.

[0046] PoP device 103 is used to send service messages to a second device via software-defined wide area network (SD-WAN) technology. The first device and the second device are located in different regions.

[0047] For example, the PoP device 103 can be a network node device, which can be composed of network devices such as routers, switches, and servers, and can be deployed on land, including indoors, outdoors, or in vehicles.

[0048] In some embodiments, the cross-border network system 10 may further include: a provider edge (PE) device 104, a unified management platform 105, and a software-defined networking (SDN) control center 106. The PE device is communicatively connected to the first device 101 and to the PoP device 103. Furthermore, the second device 102 is communicatively connected to the PoP device 103.

[0049] PE device 104 is used to receive information from the first device and forward the information to the MPLS VPN backbone network.

[0050] The unified management platform 105 is used to detect faults in network links built based on SD-WAN technology and to troubleshoot them in a timely manner. In addition, it is used to load configuration information into the second device 102 and to build the network link between the first device 101 and the second device 102.

[0051] SDN Control Center 106 is used for centralized control of PE devices 104 in the MPLS VPN network.

For example, "included in" in the embodiments of this application can be replaced with "carried on" or "carried in," etc.

[0069] like Figure 3The illustration shows a method for constructing a cross-border network according to an embodiment of this application. The method includes:

[0070] S301. Obtain connection request information from the first device.

[0071] Optionally, the connection request information may include at least one of the following: the Internet Protocol (IP) address, interface type, interface number, authentication information, and other information (e.g., business requirement information) of the first device. This application embodiment does not limit this.

[0072] Furthermore, optionally, the connection request information from the first device can be obtained by the cross-border network system triggering a query task through a timer to obtain the connection request information from the first device. Alternatively, it can be obtained by listening to the first device based on Socket programming technology to obtain the connection request information from the first device. Another option is to periodically receive heartbeat information from the first device and obtain the connection request information through the heartbeat information.

[0073] S302. Based on multi-protocol label switching virtual private network technology, establish a network link between the first device and the network access point (PoP) device.

[0074] In one possible implementation, the process of the first device accessing the MPLS VPN backbone network can be as follows: The MPLS VPN backbone network can be configured based on connection request information, and access configuration information can be generated. Then, a label-switched path (LSP) tunnel is dynamically established based on the access configuration information and the label distribution protocol (LDP), and a VPN instance is created on the provider edge (PE) device. Next, routes are configured for the first device and the PE device based on the VPN instance. The access configuration information can include the protocol type used to establish the connection between the first device and the MPLS VPN backbone network, such as the Open Shortest Path First (OSPF) protocol. The VPN instance can include: creating a routing table and forwarding policy for the first device; and the LSP tunnel is used to transmit information sent by the first device after the network connection is established.

[0075] It is understandable that both the first device and the PoP device can access the MPLS VPN backbone network through the above method. When both the first device and the PoP device are connected to the MPLS VPN backbone network, the first device and the PoP device can establish a network connection through the MPLS VPN backbone network.

[0076] S303, based on Software-Defined Wide Area Network (SD-WAN) technology and 5G slicing technology, establishes a network link between the PoP device and the second device.

[0077] In one possible implementation, Internet Protocol Security (IPsec) tunnel parameters can be determined based on Internet Key Exchange version 2 (IKEv2), and an IPsec tunnel can be constructed based on these parameters. This IPsec tunnel serves as the network link between the PoP device and the second device. The IPsec tunnel parameters include the encryption algorithm, security authentication method, and key exchange method.

[0078] It should be understood that the encryption algorithm in the IPsec tunnel parameters can be 256-bit Advanced Encryption Standard (AES-256), the security authentication method can be pre-shared key (PSK) authentication, and the key exchange method can be elliptic curved iffie-hellman ephemeral key exchange (ECDHE). This application embodiment does not limit this.

[0079] In one possible implementation, prior to the S303 process described above, the following steps are included: performing a preprocessing operation on the second device, which is used to preload configuration information. The preprocessing operation includes loading SD-WAN configuration and 5G slicing configuration.

[0080] Optionally, the preprocessing operation on the second device can be performed by: sending configuration policy information to the second device through a unified management platform, and the second device loading configuration information based on the configuration policy information. Alternatively, an automated script can be written and combined with a predefined configuration template to load configuration information for the second device.

[0081] In one possible implementation, the above-mentioned S303 implementation process can also be: establishing a network link between the PoP device and the second device based on the configuration information loaded in the preprocessing operation, SD-WAN technology, and 5G slicing technology.

[0082] In some embodiments, 5G slicing configurations and 4G and / or 5G hardware configurations may also be loaded.

[0083] The 5G slice configuration can be used to ensure the second device's access to the SD-WAN network. It can also be used to implement differentiated services. Specifically, when the second device sends a service request, the priority of the request is determined through the 5G slice configuration information, thus providing customized network services for different service needs. The 4G and / or 5G hardware configuration provides hardware guarantees for the second device's access to 4G or 5G. Furthermore, the 4G and / or 5G hardware configuration includes a hardware structure capable of inserting a Subscriber Identity Module (SIM) card, which provides authentication information when accessing the SD-WAN network and transmitting data. Based on the above technical solutions, the cross-border network construction method provided in this application establishes a network connection between the first device and the PoP device through MPLS VPN technology, and between the PoP device and the second device through SD-WAN technology. The hardware cost required for establishing a network connection through SD-WAN technology is lower than that required for establishing a network connection through MPLS VPN technology, and the network deployment process is simpler. Therefore, this application can reduce the link deployment cost of cross-border communication.

[0084] In some embodiments, traffic information of the network link between the second device and the PoP device can be obtained; based on the traffic information, link failure information can be generated; the link failure information includes the specific link that failed, the time of the failure, and the device information of the failed link; based on the link failure information, a routing policy can be generated and sent to the second device and the PoP device; the routing policy is used to switch the traffic of the failed link to the backup link.

[0085] For example, when the traffic is less than a preset traffic threshold, the cross-border network system sends a probe message to the PoP device. If the response time of the probe message is greater than 400ms and a "request pause" message appears, it can be considered a connection interruption failure. Afterwards, the connected PoP device can be switched to a backup PoP device, and a routing policy between the second device and the backup PoP device can be generated. The cross-border network system then sends the aforementioned routing policy to both the second device and the PoP device.

[0086] In one possible implementation, a data transmission method is provided, comprising: a first device sending service messages to a network access point (PoP) device via Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) technology, wherein the first device and the PoP device are located in the same region; and the PoP device sending service messages to a second device via Software Defined Wide Area Network (SD-WAN) technology, wherein the first device and the second device are located in different regions.

[0087] In one possible implementation, the method further includes: acquiring communication device information, network status information, and service requirement information; the device information includes first device information, second device information, and PoP device information; the network status information includes network status information between the first device and the second device; and the service requirement information includes service requirement information for data transmission through the network link between the first device and the second device; and determining a network service strategy based on the device information, network status information, and service requirement information.

[0088] In one possible implementation, the business requirement information includes at least one of the following: business priority, business confidentiality requirement, and latency requirement; the network service strategy includes at least one of the following: when the business priority of a business message is greater than a preset priority threshold, improve the sending timing of the business message; when the business message has a business confidentiality requirement, transmit the business message through encrypted transmission; when the latency requirement of a business message is less than a preset latency threshold, adjust the network parameters for transmitting the business message.

[0089] For example, when the business message is a real-time interactive business, such as video conferencing, online games, and remote collaboration, the network latency of such real-time interactive businesses is usually less than or equal to 80ms. A fast handshake protocol can be used, such as the fast open mechanism of the Transmission Control Protocol (TCP), or other methods can be used to improve the transmission efficiency of business messages. This application embodiment does not limit this.

[0090] In some embodiments, after the connection is established, the first device and the second device transmit data through the network connection constructed by the above method. This application embodiment provides a data transmission method including: the first device sends service messages to a network access point (PoP) device through Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) technology, and the second device and the PoP device are located in the same region; the PoP device sends service messages to the second device through Software Defined Wide Area Network (SD-WAN) technology, and the first device and the second device are located in different regions.

[0091] It is understood that the aforementioned method for constructing a cross-border network can be implemented by a cross-border network construction apparatus. To achieve the aforementioned functions, the cross-border network construction apparatus includes hardware structures and / or software modules corresponding to the execution of each function.
