[0046] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0047] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The main solution of this application is to obtain data packets, classify the data packets, and obtain classification results; determine the priority information of the data packets based on the classification results; perform protocol mapping on the priority information to obtain general priority information; and forward the data packets based on the general priority information.

[0049] Currently, network switches commonly use the 802.1p protocol to implement QoS (Quality of Service) management and priority processing. This protocol manages traffic priorities by providing up to eight priority levels for the Priority Code Point (PCP) field in Ethernet frames. However, the existing 802.1p protocol is inflexible in traffic management. While 802.1p priority levels can support basic traffic classification, there is still a gap between its priority division and the diverse needs of actual application scenarios, resulting in unstable network traffic transmission. Therefore, how to improve the stability of network traffic transmission remains an unresolved issue.

[0050] This application maps priority information to obtain universal priority information, which can smoothly forward traffic on various switches, manage network traffic in more detail, and improve the stability of network traffic transmission.

[0051] Based on this, the embodiment of the present application provides a method for forwarding data packets based on priority, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the priority-based data packet forwarding method of the present application.

[0052] In this embodiment, the priority-based data packet forwarding method includes steps S10 to S40:

[0053] Step S10: Acquire a data packet, classify the data packet, and obtain a classification result;

[0054] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, a priority-based packet forwarding device, etc. The following describes this embodiment and the following embodiments using a priority-based packet forwarding device as an example.

[0055] As you can understand, every packet in the network is labeled and classified into different traffic types. The classification process is based on multiple factors such as the packet's content, source, destination, and protocol.

[0056] In a feasible manner, the step of classifying the data packet and obtaining the classification result includes: extracting the multidimensional feature parameters of the data packet, the multidimensional feature parameters including at least content, source address, destination address and protocol type; determining the traffic type of the data packet using the multidimensional feature parameters; and determining the classification result based on the traffic type.

[0057] It is understood that multi-dimensional features include at least content, source address, destination address, and protocol type. The multi-dimensional feature parameters are used to determine the traffic type of the packet, such as voice traffic, video traffic, and data traffic. Different traffic types have different priorities in different scenarios, so traffic priorities need to be differentiated to ensure that important traffic is forwarded first.

[0058] It should be noted that in order to simplify the management and configuration of 802.1p priority, this embodiment provides a unified priority management platform. This platform can help administrators easily configure traffic priority rules in the network. The platform provides a user-friendly graphical operation interface, and network administrators can configure priority policies by simply dragging and selecting. There is no need to configure each device separately through the command line, which improves management efficiency; once the administrator completes the configuration of the priority policy, the platform will automatically push the configuration to all required switch devices. This process reduces the complexity of manual operations and the occurrence of errors. The platform can also monitor the priority configuration of devices in the network in real time. If the priority configuration of certain switches is found to be abnormal (such as inconsistent configuration or wrong priority), the system will automatically correct it.

[0059] Step S20: determining the priority information of the data packet according to the classification result;

[0060] As you can see, traffic types are determined based on the classification results, and then assigned to different priority queues based on business needs and network conditions. Traffic priorities can be adjusted dynamically. For example, during periods of high network load, the network will prioritize video traffic to ensure stable video calls.

[0061] Step S30: performing protocol mapping on the priority information to obtain general priority information;

[0062] It should be noted that switches from different manufacturers may use different protocols and have different priority definitions. Therefore, protocol mapping is required to identify the priority definitions of different switches and map the traffic priority information to a format supported by each switch.

[0063] In a feasible manner, the step of performing protocol mapping on the priority information to obtain general priority information includes: parsing the device protocol support list of the target switch; determining the priority compatible format based on the device protocol support list; performing protocol mapping on the priority information according to the compatible format to obtain general priority information.

[0064] It is understandable that the device protocol support list of the target switch is obtained and the original priority is adjusted to a compatible format that can be recognized by all switches. In this process, protocol parsing and mapping algorithms, cross-vendor device compatibility analysis and data packet priority information transmission and verification mechanisms are used.

[0065] Step S40: forwarding the data packet according to the general priority information.

[0066] As you can see, once traffic is marked and prioritized, the protocol mapping mechanism ensures that this information is passed throughout the network and correctly interpreted. This allows traffic priorities to be consistent across switches from different vendors, improving network performance.

[0067] In a feasible manner, the step of forwarding the data packet according to the general priority information includes: determining the priority queue of the data packet according to the general priority information; and forwarding the data packet according to the priority queue in accordance with a preset queue forwarding rule.

[0068] After forwarding the data packet according to the general priority information, the method further includes: collecting state change data of network traffic in real time; and adjusting the general priority information based on the state change data.

[0069] It is understandable that real-time traffic analysis is required during traffic transmission. Specifically, network status monitoring tools are used to collect network traffic data in real time and analyze traffic trends and congestion conditions in the network. For example, when a certain service's traffic surges, this change will be detected. Based on the results of the real-time analysis, the priority of the traffic needs to be adjusted. For example, when there is excessive data traffic at a certain moment, the priority of non-critical services will be lowered to ensure that the high priority of critical services (such as voice or video) is guaranteed. This mechanism uses dynamic algorithms, such as adjustment algorithms based on bandwidth prediction or traffic prediction models, to handle traffic priority adjustments.

[0070] It should be noted that the hardware used in this embodiment includes switch hardware, which must support the SONiC system and have high-performance data processing capabilities. The hardware acceleration function can improve the efficiency of protocol expansion, dynamic priority adjustment and traffic optimization; the network controller is responsible for managing the intelligent analysis and control of network traffic, can adjust the priority setting according to the network status, and pass the configuration information to the switch; the management platform provides network administrators with a graphical operation interface and management tools to ensure a simplified configuration process.

[0071] This embodiment obtains data packets, classifies the data packets to obtain classification results; determines priority information of the data packets based on the classification results; performs protocol mapping on the priority information to obtain general priority information; and forwards the data packets based on the general priority information.

[0072] In summary, this embodiment maps priority information to obtain universal priority information, which can smoothly forward traffic on each switch, manage network traffic in more detail, and improve the stability of network traffic transmission.

[0073] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 2 , step S20 further includes steps S201 to S202:

[0074] Step S201: Acquire state parameters of current network traffic, including bandwidth utilization and service delay;

[0075] It is understandable that when determining the priority of a data packet, it is not only necessary to divide the priority according to the parameters and type of the data packet itself, but also to combine the status of network traffic and determine the most appropriate priority of the data packet under different network traffic conditions.

[0076] Step S202: Priority information is calculated based on the classification result and the state parameter according to a preset priority strategy.

[0077] As you can understand, data packets are classified into voice, video, and data traffic. Traffic is assigned to different priority queues based on service needs and network conditions. Traffic priorities can be adjusted dynamically. For example, during periods of high network load, the network will prioritize video traffic to ensure stable video calls. Traffic priorities are not fixed but are adjusted based on real-time monitoring of network traffic. The system dynamically adjusts the priorities of different traffic types based on real-time network status analysis and parameters such as bandwidth utilization. This effectively avoids network congestion and prioritizes critical business traffic.

[0078] In a feasible manner, before calculating the priority information based on the classification result and the state parameter according to a preset priority strategy, the method further includes:

[0079] receiving an operation instruction, wherein the operation instruction is generated by a user by dragging the visualization module;

[0080] Obtaining a preset priority strategy according to the operation instruction;

[0081] The preset priority policy is synchronized to the target switch device.

[0082] It is understandable that this embodiment provides a graphical operation interface and management tool for network administrators, and administrators can complete policy configuration by dragging and dropping rather than commands, which reduces the configuration difficulty and simplifies the configuration process.

[0083] This embodiment obtains status parameters of current network traffic, which include bandwidth utilization and service delay; and calculates priority information based on the classification result and the status parameters according to a preset priority strategy.

[0084] This embodiment determines the priority information of the data packet through the state parameters and the classification result, which can ensure that important data packets can be forwarded smoothly during data packet forwarding, thereby improving the stability of network traffic transmission.

[0085] For example, in order to help understand the implementation process of the priority-based data packet forwarding method obtained by combining this embodiment with the above embodiment 1, please refer to Figure 3 , Figure 3 This paper provides a simplified flowchart of a priority-based packet forwarding method. Specifically, it begins with network initialization and configuration, setting up a preliminary traffic priority policy. This is followed by packet classification and priority assignment, categorizing and assigning traffic priorities. This is followed by protocol mapping and conversion, ensuring priority consistency through protocol conversion. This is followed by cross-switch coordination, ensuring priority information is passed between switches. Finally, real-time traffic monitoring and priority adjustment are performed, dynamically adjusting priorities to cope with traffic fluctuations. Furthermore, priority management and configuration push are implemented, pushing priority configurations to all switches. Finally, problem detection and correction are performed, automatically correcting configuration issues.

[0086] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the priority-based packet forwarding method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0090] A mapping module 30, configured to perform protocol mapping on the priority information to obtain universal priority information;

[0092] This embodiment obtains data packets, classifies the data packets to obtain classification results; determines priority information of the data packets based on the classification results; performs protocol mapping on the priority information to obtain general priority information; and forwards the data packets based on the general priority information.

[0093] In summary, this embodiment maps priority information to obtain universal priority information, which can smoothly forward traffic on each switch, manage network traffic in more detail, and improve the stability of network traffic transmission.
