[0002] Currently, with the rapid development of science and technology, data transmission scenarios in various industries are increasing. When there are massive amounts of data resources to be transmitted through the network, existing technologies are unable to perceive the data elements contained in the transmitted messages at the network device level, nor are they able to perceive the requirements that these data elements place on the network. For example, highly sensitive data elements may require the data transmission process to be visible and the data transmission path to not cross the border. However, since the current network cannot perceive these data elements, it is also unable to know the corresponding transmission requirements. As a result, during the data transmission process, the transmission requirements of the messages may not be met, which greatly affects data security and data validity.

DETAILED DESCRIPTION

[0017] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0019] Example 1 Figure 1 This is a flow chart of a method for forwarding data packets in an SRv6 network provided in Example 1 of the present application. Figure 1 As shown, the method includes: S11, after receiving the data message, obtaining data identification information of the data message; SRv6 (Segment Routing over IPv6) is an IPv6-based segment routing technology that enables flexible traffic engineering and network programmability by embedding a segment list in the IPv6 header. Each segment is an IPv6 address that represents a specific functional point in the network, such as a node, service, or operation. SRv6 allows network devices to process and forward packets hop by hop based on the segment list in the header, eliminating the need for traditional destination-based routing tables. This enables fine-grained traffic control and service chaining.

[0020] A datagram can contain an IPv6 basic header, an Segment Routing Header (SRH) extension header, an optional Hop-by-Hop Options header, and payload data. The payload data can follow the format of a specific protocol, such as TCP / UDP, HTTP / 2, and QUIC, or a custom format.

[0021] Data identification information refers to the characteristic labels carried by the data itself, such as: data type identification, which can be medical data, financial data, or general office data, security level marking, such as top secret, confidential, or public, transmission constraints, such as domestic transmission and / or low latency priority, compliance requirements, such as compliance with the Personal Information Protection Law and / or meeting industry regulatory standards, etc.

[0022] In this solution, the network device can receive message data through the physical interface. For the collection of data packets, it can receive frame by frame and perform link layer frame detection, including identifying the frame header, frame tail and check bit.

[0023] S12, parsing the data identification information to obtain transmission requirement information of the data element; Data identification information refers to the tags or metadata carried in a message that describe the characteristics of data elements. Data type tags include, for example, medical data types, financial transaction types, and government information types. Security attribute tags include, for example, high sensitivity, cross-border restrictions, and encrypted transmission requirements. Compliance requirements include, for example, meeting domestic transmission regulations.

[0024] Data elements are data units with specific business value and attributes, and they carry data identification information. Examples include sensitive data such as personal identity information, medical records, or trade secrets. They also include time-sensitive data such as real-time video streams and industrial control instructions. They also include geographically constrained data such as cross-border user behavior data.

[0025] Transmission requirements refer to the specific requirements for network transmission paths and services, derived from data identification information. Examples include path constraints, such as requiring transmission through domestic nodes or prohibiting transmission through specific countries; security services, such as end-to-end encryption, intrusion detection, and data desensitization; and quality of service requirements, such as latency less than 50ms, bandwidth greater than 100Mbps, and packet loss less than 0.1%.

[0026] This solution can extract data tags from the message header and convert the data identifier into transmission requirements based on preset corresponding rules. For example, if the data identifier 0011 is included, it means that domestic transmission is required, etc.

[0027] S13, mapping the transmission requirement information to a network identifier and encapsulating it into a header of a data message; The network identifier refers to the coded representation of transmission requirements in the SRv6 network, which can generally be an IPv6 address or a special field.

[0028] The data packet header may refer to an SRv6 extension header, such as the Segment Routing Header (SRH), which includes a segment list and a pointer to the currently active segment, the Destination Options Header (DOH), which carries hop-by-hop processing instructions, and the Hop-by-Hop Options (HBH), which carries options visible to all nodes.

[0029] The encapsulation method may be to encode the network identifier into an IPv6 address segment and insert the segment list of the SRH.

[0030] In this solution, transmission requirement information can be mapped to a network identifier, using a specific network identifier to represent the requirement. For example, multiple bits can be set, with each bit filled with 0 or 1 to represent different requirements. For example, when domestic transmission is required, the bit for domestic transmission is filled with 1, otherwise it is filled with 0, thus achieving the mapping of transmission requirement information to network identifiers. In this way, in subsequent device nodes, as long as the written value of each bit is recognized, the transmission requirement information of the message data can be parsed, thereby performing fast and demand-compliant forwarding.

[0031] S14: Forward the data message according to the network identifier.

[0032] The network device can forward the data packet from the current device node to the next device node based on the message header information. Specifically, it can find the next device node that meets the requirements based on the IPv6 destination address.

[0033] The technical solution provided by this embodiment solves the problem of traditional networks' inability to effectively forward packets by deeply integrating data characteristics with network transmission capabilities. This enables network devices to understand the inherent needs of message data, achieve intelligent forwarding, and control different transmission requirements based on the needs of different data transmission services, providing high flexibility at the control level. This solution dynamically allocates network resources based on real-time needs, improving the rationality of data transmission, ensuring the security and effectiveness of data transmission, and avoiding the problem of transmitted data being unavailable due to transmission path issues.

[0034] In one embodiment, optionally, mapping the transmission requirement information to a network identifier and encapsulating the information into a header of a data message includes: Create a network identification flag in the header of the data message; After mapping the transmission requirement information to a network identifier, the network identifier is written into a corresponding flag bit; The header of the data message is encapsulated.

[0035] The network identifier flag bit refers to the specific field or coding space in the data packet header used to carry the network identifier. It is the physical carrier for the SRv6 network to identify transmission requirements.

[0036] Transmission requirement information refers to specific requirements such as path constraints, security services, and QoS (Quality of Service) parameters, which must be converted into binary or text encoding that can be recognized by the network.

[0037] According to the SRv6 protocol specification, this solution can determine one or more bits of fields as flag bits in the reserved extension space of the message header. For example, every 2 bytes is used as a flag bit. Then, if there are four transmission requirement data that need to be limited, a total of 8 bytes can be provided, and every 2 bytes are used as the flag bit corresponding to a transmission requirement.

[0038] In this solution, the encoded network identifier can be written into the packet header according to the address or field offset of the flag bit. For example, the header fields can be directly modified using a network programming interface. The data packet header is then encapsulated. Specifically, the basic header, SRH, and other extension headers can be spliced according to the IPv6 protocol specification, and the correct field order can be ensured during the encapsulation process.

[0039] This technical solution can provide a carrier for the transmission requirements of data elements by mapping transmission requirement information into a network identifier and encapsulating it into a message header. It uses the SRv6 extension header mechanism to create a standardized flag bit to provide a physical carrier for requirement encoding. It converts abstract requirements into network-recognizable addresses or field values through regular mapping, so that SRv6 device nodes can directly parse the requirements and ensure that the message is readable hop by hop in the network environment through header encapsulation, so that network devices can dynamically adjust forwarding strategies based on data attributes, which not only ensures the compliance and security of data transmission, but also realizes link optimization.

[0040] In one embodiment, optionally, the flag bit corresponding to the network identifier includes: one or more of a path visibility flag bit, a domestic transmission path flag bit, a low-latency slice flag bit, and a high-priority transmission path flag bit.

[0041] Among them, the path visibility flag is used to indicate that the data transmission path must support full-process monitoring or auditing to ensure the transparency of data flow.

[0042] The domestic transmission path flag is used to force the data transmission path not to cross the national border to ensure that the data does not leave the country.

[0043] The low-latency slice flag is used to request the network to allocate low-latency dedicated slices for data to ensure real-time requirements.

[0044] The high-priority transmission path flag is used to allocate high-priority resources in the network to data, giving it priority over normal traffic.

[0045] This technical solution, through the refined design of the above-mentioned flag bits, realizes the network's accurate perception of the data element transmission needs. It can be based on the flag bit design of the standard IPv6 extension header, and can achieve network-level perception without the need for large-scale transformation of existing network equipment. In addition, since the flag bit corresponding to the network identifier is set in the header, the security of data information is ensured.

[0046] In one embodiment, optionally, forwarding the data packet according to the network identifier includes: Determine one of at least two candidate lower-level device nodes as a target device node according to the network identifier; Forward the data message to the target device node.

[0047] Candidate lower-level device nodes refer to a group of potential forwarding nodes in the network that are located downstream of the current node and can receive and process data packets.

[0048] The target device node refers to the node that is selected from the candidate nodes and best meets the transmission requirements expressed by the data message network identifier.

[0049] The current node reads the network identifier in the message header, identifies the transmission requirement, and prioritizes the new transmission requirement based on its functional compatibility, path compliance, and real-time status, including node load, congestion level, and link quality.

[0050] This technical solution uses dynamic path selection through network identification to provide secure paths for sensitive data and automatically select low-latency links for real-time services. Furthermore, this solution can be implemented through the SRv6 extension header without modifying the underlying network architecture, providing network infrastructure support for the secure and efficient flow of data elements.

[0051] In one embodiment, optionally, after forwarding the data message according to the network identifier, the method further includes: After receiving the data message, each device node in the SRv6 network is controlled to identify the network identifier encapsulated in the header of the data message.

[0052] SRv6 network device nodes may include routers, switches, or dedicated function nodes such as firewalls and encryption devices.

[0053] This technical solution unifies nodes' ability to identify and process network identifiers, ensuring that data packets are correctly understood and processed across the entire SRv6 network, avoiding deviations in demand execution caused by inconsistent node behavior. Nodes automatically execute predefined actions based on identifiers, and in exceptional circumstances, unprocessable requests can be detected and reported in real time, ensuring that all nodes strictly adhere to geographic constraints, security policies, and other requirements to meet data transmission requirements.

[0054] Example 2 Figure 2 This is a flow chart of a method for forwarding data packets in an SRv6 network provided in Example 2 of the present application. Figure 2 As shown, the method includes: S21, after receiving the data message, read the network identifier encapsulated in the header of the data message; S22, if the current device node is not the final device node, determining one of at least two candidate lower-level device nodes as the target device node according to the network identifier; S23: Forward the data message to the target device node.

[0055] The technical solution provided in this embodiment may be a specific operation performed in the downstream device node of the above embodiment, corresponding to the operation of the device node provided in the above embodiment, and having a functional module and beneficial effects corresponding to the threshold. To avoid repetition, it will not be repeated here.

[0056] Example 3 In order to enable those skilled in the art to understand the present solution more clearly, the present application also provides a preferred embodiment. Figure 3 Schematic diagram of a data message forwarding system in an SRv6 network provided in Example 3 of the present application; Figure 3 As shown, this system can perform the following steps to complete the monitoring of data circulation services: When a network device receives a message containing data elements, it checks the data identification information it carries.

[0057] By reading the data identification information, which contains the network requirements of the data element during transmission, the data element's requirements for network transmission are obtained, such as path visibility, domestic transmission path, low-latency slicing, high-priority transmission path, etc.

[0058] After that, the read demand information is mapped to the flag bit corresponding to the network identifier, and the network identifier is encapsulated into the header of the message. Since it is subsequently transmitted in the SRv6 network, the network identifier can be encapsulated in the SRH, DOH, HBH and other message headers, and forwarded to the subsequent device nodes of the SRv6 network according to the rules, ensuring that the network identifier can be read by each device node in the SRv6 network, thereby solving the problem of the network being unable to perceive data elements.

[0059] This application provides a method and system for network identification of data elements, applicable to scenarios where data elements are transmitted in SRv6 networks. The method includes: converting and mapping network identifiers to data identifiers, and carrying the network identifier in the SRv6 network message header for transmission, so that each node device in the network can perceive the corresponding data element's network transmission requirements through the network identifier. This method can effectively solve the problem of the network being unable to perceive data elements.
