The network elements receive the modal configuration policies, generate processing policies corresponding to the network modes based on the modal configuration policies, and when they receive service messages sent by terminals, they determine the network mode required by the terminals (i.e., the target network mode), process and forward the received messages based on the processing policies corresponding to the target network mode, thereby realizing communication between terminals and meeting the network requirements of the terminals. As can be seen, the network system disclosed in this application can support multiple network modes, meaning it can carry multiple network requirements. Furthermore, when it is necessary to expand the network requirements carried by the network system, it is only necessary to construct a network mode that supports that network requirement. The mode control system generates a mode configuration policy for that network mode and sends the mode configuration policy to the relevant network elements.

Subsequently, the network requirements of the terminal can be met. In other words, the network system disclosed in this application can carry multiple network requirements and can easily expand the network requirements carried by the network system.

[0038] This application provides a network system capable of supporting various network requirements. This application also discloses a communication method implemented based on this network system.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] See Figure 1 , Figure 1 This is a schematic diagram of the structure of a network system disclosed in this application. The network system includes a modal control system 100 and a multimodal network platform 200.

[0041] The multimodal network platform 200 includes multiple network elements, which can communicate with each other.

[0042] A network element is a network device used to process and forward data. For example, switches and routers are both network elements.

[0043] In implementation, multiple network elements in the multimodal network platform 200 are interconnected through various media or transmission networks, enabling data exchange and communication between them. Each network element in the multimodal network platform 200 can communicate with at least one other network element. Optionally, each network element in the multimodal network platform 200 can communicate with multiple other network elements.

[0044] exist Figure 1 In the example shown, the multimodal network platform 200 includes four network elements; however, this is just one example. In practical applications, the multimodal network platform 200 typically includes more network elements.

[0045] The modal control system 100 is used to: generate modal configuration strategies for various network modes, and send the modal configuration strategies to the network elements involved in each modal configuration strategy. Each network mode is used to support / implement specific network requirements.

[0046] The network elements in the multimodal network platform 200 are used to: receive mode configuration policies, generate processing policies corresponding to network modes based on mode configuration policies; when a service message sent by a terminal is received, determine the target network mode required by the terminal, and process and forward the received service message based on the processing policy corresponding to the target network mode to realize communication between terminals.

[0047] In practice, the service messages sent by the terminal carry an identifier of the network mode required by the terminal. Based on the network mode identifier carried in the service message, the network element can determine the network mode required by the terminal. For ease of description, the network mode required by the terminal is referred to as the target network mode.

[0048] Network Mode: Each physical network entity defined according to its network technology architecture, supported industry applications, operation and maintenance system, and deployment method can be abstracted into a network mode that can run in the network environment through standardized hardware and software interfaces. Each network mode is used to support / implement specific network requirements.

[0049] In other words, technicians abstract / construct corresponding network modes based on users' network needs. A network mode is a network technology system, and network elements process and forward packets sent by terminals according to the processing strategy corresponding to each network mode.

[0050] During implementation, user network requirements are analyzed to construct corresponding network modes. The modal control system 100 generates corresponding modal configuration policies for each network mode and sends these policies to the network elements involved in each policy. It should be noted that a modal configuration policy may only involve a subset of network elements in the multimodal network platform 200.

[0051] This section describes the modal configuration strategy for network modal generation in the modal control system 100.

[0052] The modal control system 100 acquires the network operation logic file written by the technicians for the network mode, compiles the network operation logic file, and the compiled file is the modal configuration strategy corresponding to the network mode.

[0053] Optionally, modal configuration strategies include addressing mode, message format, routing protocol, signaling mode, computing mechanism, storage mechanism, forwarding mechanism, switching mode, scheduling mechanism, and security mechanism.

[0054] Correspondingly, the network elements in the multimodal network platform 200 receive the mode configuration policy of the network mode sent by the mode control system 100, and generate the corresponding processing policy of the network mode based on the mode configuration policy, including: generating the addressing policy of the network mode based on the addressing method; generating the packet parsing policy of the network mode based on the packet format; generating the routing policy of the network mode based on the routing protocol; generating the signaling parsing policy of the network mode based on the signaling method; generating the calculation policy of the network mode based on the calculation mechanism; generating the storage policy of the network mode based on the storage mechanism; generating the forwarding policy of the network mode based on the forwarding mechanism; generating the switching policy of the network mode based on the switching method; generating the scheduling policy of the network mode based on the scheduling mechanism; and generating the security policy of the network mode based on the security mechanism.

[0055] Optionally, the modal configuration strategy may also include a quality of service mechanism and / or an operation and maintenance management mechanism.

[0056] Accordingly, the network element generates the processing strategy corresponding to the network mode based on the modal configuration strategy, and also includes: generating the service strategy corresponding to the network mode based on the quality of service mechanism; and / or, generating the operation and maintenance management strategy corresponding to the network mode based on the operation and maintenance management mechanism.

[0057] In existing technologies, a network device can only run one processing strategy, and once the processing strategy of a network device is set, it is difficult to change the processing strategy it runs. Therefore, in existing technologies, a network system composed of multiple network devices can only support a single network requirement. It is difficult to change the network requirements supported by the network system or to expand (i.e., increase) the network requirements supported by the network system.

[0058] The network element in this application is a network device based on fully definable technology that supports the coexistence of multiple network modes. In other words, the network element in this application stores and can execute processing strategies corresponding to multiple network modes, that is, it can provide hardware and software support for the technical implementation of various network modes, has dynamic allocation, management and guarantee functions of hardware and software resources, and can support the deployment and operation of multiple network modes and related applications.

[0059] Specifically, after receiving the mode configuration policy corresponding to the network mode sent by the mode control system 100, the network element generates a corresponding processing policy based on the mode configuration policy (including addressing policy, packet parsing policy, routing policy, signaling parsing policy, calculation policy, storage policy, forwarding policy, switching policy, scheduling policy, security policy, and may also include service policy and / or operation and maintenance management policy); when receiving a service packet sent by the terminal, the target network mode required by the terminal is determined, and the received service packet is processed and forwarded based on the processing policy corresponding to the target network mode, thus meeting the network requirements of the terminal.

[0060] Optionally, the network modes in this application include: network modes that support high bandwidth network requirements, network modes that support latency-sensitive network requirements, network modes that support location-sensitive network requirements, and network modes that support content identification network requirements.

[0061] Of course, the network system disclosed in this application can support more network modes; the above is merely an example. Network modes can be constructed to support / implement various network requirements for different user needs.

[0062] For example, in the industrial, military, energy, transportation, financial, government, power, agricultural, mobile, and satellite communication sectors, users may have diverse network requirements from the perspectives of high efficiency, high throughput, time sensitivity, reliability, mobility, security, and scalability. To address these diverse user network requirements, technical personnel construct corresponding network modes and write network operation logic files based on these requirements, sending these files to the mode control system. The mode control system generates corresponding mode configuration policies for each network mode and sends these policies to the relevant network elements. The network elements receive the mode configuration policies and generate processing policies corresponding to the network modes based on these policies, thus completing the loading of the network modes.

[0063] The network system disclosed in this application includes a modal control system and a multimodal network platform. The multimodal network platform includes multiple network elements that can communicate with each other. The modal control system generates modal configuration policies for various network modes (each network mode is used to support specific network requirements) and sends the modal configuration policies to the network elements involved in each modal configuration policy. The network elements receive the modal configuration policies, generate processing policies corresponding to the network modes based on the modal configuration policies, and when they receive service messages sent by terminals, they determine the network mode required by the terminals (i.e., the target network mode), process and forward the received messages based on the processing policies corresponding to the target network mode, thereby realizing communication between terminals and meeting the network requirements of the terminals. As can be seen, the network system disclosed in this application can support multiple network modes, meaning it can carry multiple network requirements. Furthermore, when it is necessary to expand the network requirements carried by the network system, it is only necessary to construct a network mode that supports that network requirement. The mode control system generates a mode configuration policy for that network mode and sends the mode configuration policy to the relevant network elements. The network elements then generate the corresponding processing policy based on the received mode configuration policy, completing the loading of that network mode. Subsequently, the network requirements of the terminal can be met. In other words, the network system disclosed in this application can carry multiple network requirements and can easily expand the network requirements carried by the network system.

[0064] In another embodiment of the network system in this application, the modal control system 100 is further configured to:

[0065] The target network requirements sent by the receiving terminal;

[0066] A network mode is constructed for the target network requirement, a mode configuration policy corresponding to the target network requirement is generated, and the mode configuration policy corresponding to the target network requirement is sent to the network elements involved.

[0067] Send the identifier of the network mode constructed for the target network requirements to the terminal.

[0068] The network system disclosed in this application, during the initialization phase, involves a modal control system 100 generating modal configuration strategies for various network modes and sending each strategy to the relevant network elements. Each network element receives the modal configuration strategies and generates a corresponding processing strategy for the network mode based on the received strategies, thereby loading the network mode. Terminals can select one of the multiple network modes supported by the network system and communicate within that mode.

[0069] If the terminal has new network requirements, it sends these new network requirements (i.e., target network requirements) to the modal control system 100. The modal control system 100 constructs a network mode for the target network requirements sent by the terminal, generates a corresponding mode configuration policy, and sends this policy to the relevant network elements, thereby loading the new network mode to meet the terminal's new network requirements. Additionally, the modal control system 100 sends an identifier of the network mode constructed for the new network requirements to the terminal, enabling the terminal to communicate within that network mode based on this identifier.

[0070] In another embodiment of the network system in this application, the modal control system 100 is further configured to:

[0071] Obtain the status information of network elements;

[0072] Update the mode configuration strategies corresponding to various network modes based on state information;

[0073] Send the updated modal configuration policy to the network elements involved in the updated modal configuration policy.

[0074] The state of each network element in the multimodal network platform 200 will change. In order to ensure better communication, the modal control system 100 updates the modal configuration strategy corresponding to each network mode based on the state information of each network element, and sends the updated modal configuration strategy to the relevant network elements.

[0075] The modal control system 100, acting as the controller of the multimodal network platform, serves as the management hub of the entire network system. The modal control system 100 acquires the status information of each network element according to a preset period. For example, the modal control system 100 periodically sends probe commands to each network element using in-band telemetry. Each network element, based on the probe commands sent by the modal control system 100, encapsulates its status information in a probe and sends it back to the modal control system 100. Alternatively, each network element sends its own status information to the modal control system 100 according to a preset period.

[0076] Optionally, the status information of network elements includes: queue information, processing latency, memory information, CPU status, timestamp, link load, and packet status information (such as forwarding path, forwarding latency, and throughput).

[0077] In another embodiment of the network system in this application, the modal control system 100 is further configured to: send a network mode offloading instruction to a network element, the network mode offloading instruction carrying an identifier of the network mode to be offloaded. Correspondingly, the network element is further configured to: respond to the network mode offloading instruction and delete the processing strategy corresponding to the network mode to be offloaded.

[0078] The network system disclosed in this application can conveniently load and unload network modes. When it is necessary to unload a certain network mode, the mode control system 100 sends a network mode unloading instruction (carrying an identifier of the network mode to be unloaded) to the network element. The network element responds to the network mode unloading instruction sent by the mode control system 100 and deletes the processing strategy corresponding to the network mode carried by the identifier, thus completing the unloading of the network mode.

[0079] In another embodiment of the network system in this application, the multimodal network platform 200 includes multiple network elements that are heterogeneous.

[0080] The hardware and software resources of a network element include computing resources, storage resources, and forwarding resources.

[0081] The computing resources include, but are not limited to: CPU (central processing unit), GPU (graphics processing unit), FPGA (Field Programmable Gate Array), and ASIC (Application Specific Integrated Circuit). Storage resources include, but are not limited to: hard disks, TACM (Tri-State Content-Addressable Memory), and RAM (Random Access Memory). Forwarding resources include, but are not limited to: circuit / packet switching, time slots, and other resources.

[0082] In the network system disclosed in this application, the network elements need to provide hardware and software support for the technical implementation of multiple network modes. In other words, the network elements need to support multiple network requirements. The multimodal network platform 200 is composed of heterogeneous network elements, which is beneficial for the modal control system 100 to dynamically call and combine different hardware and software resources to support diverse network requirements according to different network needs.

[0083] The following is combined with Figure 2 The application of the network system disclosed in this application is explained.

[0084] The network system supports multiple network modes, such as Figure 2 The diagram shows network modes that support high bandwidth network requirements, latency-sensitive network requirements, location-sensitive network requirements, and content-identification network requirements. Accordingly, the network system can meet the high bandwidth, latency-sensitive, location-sensitive, and content-identification network requirements of the terminals.

[0085] The terminal can select any network mode supported by the network system and communicate in that network mode. Alternatively, the terminal can send a target network requirement to the mode control system 100, so that the network system can construct and load a network mode to support the target network requirement, and then the terminal can communicate in that network mode.

[0086] The network system disclosed in this application supports multiple network modes, which can meet the diverse network needs of users in various scenarios. Furthermore, the network system disclosed in this application can easily load and unload network modes, and can also update various network modes. The network system disclosed in this application not only seamlessly supports the operation of existing network systems, but also supports the evolution and transformation of existing network systems, adapting to the long-term and complex nature of network system upgrades.

[0087] The network system disclosed in this application is a new paradigm for network development that separates network technology system from supporting environment. It can support various network needs to be dynamically loaded / unloaded or run on a unified network element in the form of network modalities. It can realize the coexistence, evolution or transformation of multiple network modalities on the same technical support environment, break through the constraints of the current "network and service separation" development paradigm, greatly release the innovative vitality of network technology system driven by emerging applications, and significantly reduce the threshold for application deployment and service provision of new networks.

[0088] This application also discloses a communication method based on the aforementioned network system. For example... Figure 4 As shown, the communication method includes:

[0089] S401: The terminal sends service messages to the multimodal network platform.

[0090] The service messages sent by the terminal carry the identifier of the network mode.

[0091] In practice, the terminal accesses a network element in the multimodal network platform and sends a service message to that network element. This service message carries an identifier of the network mode required by the terminal.

[0092] S402: In a multimodal network platform, network elements determine the target network mode required by the terminal based on the identifier in the service message.

[0093] S403: In a multimodal network platform, network elements process and forward received service packets based on the processing strategy corresponding to the target network mode in order to achieve communication between terminals.

[0094] In this multimodal network platform, network elements obtain modal configuration strategies from the modal control system and generate processing strategies corresponding to the network modes based on these strategies. For details regarding the scheme for network elements to generate processing strategies based on modal configuration strategies, please refer to the preceding description.

[0095] After receiving a service message from a terminal, a network element can determine the network mode required by the terminal (i.e., the target network mode) based on the network mode identifier carried in the service message. The network element then processes and forwards the received service message according to the processing strategy corresponding to the target network mode. It should be noted that, except for the network element acting as the terminal access point (i.e., the network element to which the terminal accesses), which receives service messages from the terminal, other network elements receive service messages forwarded by the previous network element and ultimately send the service message to the recipient (i.e., another terminal).

[0096] The processing procedure of a network element after receiving a service message is as follows: Figure 3 As shown. After receiving a service message, the network element determines the network mode (target network mode) required by the terminal based on the network mode identifier carried in the service message, and then... Figure 3 The network modality recognition module (software module) is implemented in the network element. Then, the network element processes and forwards the service packet based on the processing strategy corresponding to the target network modality.

[0097] A network element may process multiple service packets simultaneously. Optionally, the network element may perform mixed forwarding and scheduling of multiple service packets, which is then handled by... Figure 3 The hybrid scheduling module (software module) is implemented in the system.

[0098] Optionally, the network element may perform mixed forwarding scheduling of multiple service packets based on the priority of multiple network modes. Alternatively, the network element may perform mixed forwarding scheduling of multiple service packets based on the performance requirements of the network modes corresponding to the multiple service packets.

[0099] The communication method disclosed in this application involves a terminal sending a service message to a multimodal network platform. The service message carries an identifier of the network mode required by the terminal. A network element receives the service message sent by the terminal, determines the network mode required by the terminal (i.e., the target network mode) based on the identifier of the network mode carried in the service message, and processes and forwards the received service message based on the processing strategy corresponding to the target network mode, thereby realizing the communication of the terminal and meeting the network requirements of the terminal.

[0100] In another embodiment of the communication method in this application, it further includes:

[0101] During the initialization phase, the modal control system generates modal configuration strategies for various network modes and sends these strategies to the network elements involved in each strategy. Each network mode is used to support specific network requirements.

[0102] The network element receives the mode configuration strategy, and the corresponding processing strategy is generated based on the mode configuration strategy.

[0103] In another embodiment of the communication method in this application, it further includes:

[0104] The modal control system receives the target network requirements sent by the terminal.

[0105] The modal control system constructs network modes for the target network requirements, generates modal configuration strategies corresponding to the target network requirements, and sends the modal configuration strategies corresponding to the target network requirements to the network elements involved.

[0106] The modal control system sends the identifier of the network mode constructed for the target network requirements to the terminal.

[0107] In another embodiment of the communication method in this application, it further includes:

[0108] Modal control systems acquire the state information of network elements;

[0109] The modal control system updates the modal configuration strategies corresponding to various network modes based on state information;

[0110] The modal control system sends the updated modal configuration policy to the network elements involved in the updated modal configuration policy.

[0111] In another embodiment of the communication method in this application, it further includes:

[0112] The modal control system sends a network mode offloading instruction to the network element, which carries an identifier of the network mode to be offloaded. Accordingly, the network element also performs the following steps: responding to the network mode offloading instruction and deleting the processing strategy corresponding to the network mode to be offloaded.

[0113] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
