[0048] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0049] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0050] In one embodiment, Figure 1 As shown, a data forwarding method is provided. The method can be applied to electronic devices such as laptop computers, desktop computers, workstations, servers, and mainframe computers. The electronic device can be pre-configured with a switching module group, and the system in the electronic device can be referred to as a data forwarding system. The switching module group can be a module group consisting of at least two switching modules, and the switching modules are cascaded via a network cable. The switching module can refer to a network device used for signal or data forwarding, such as a switch, a switching chip, or a switching board. By combining at least two switching modules into a switching module group, the number of ports used for data exchange can be expanded. This embodiment does not limit the type of network cable connecting the switching modules, and can be, for example, a twisted pair cable, a coaxial cable, or an optical cable.

[0051] The method comprises:

[0052] S101, receiving a data packet to be forwarded;

[0053] The data packets may refer to block-type transmission data, which are transmitted along different paths in one or more networks and reassembled at the destination. Furthermore, the data packets to be forwarded are data packets sent by the sender for forwarding to the receiver.

[0054] S102, determining the operating state of a target switching module; wherein the target switching module is a switching module for forwarding data packets that is predetermined based on a port address;

[0055] The port address may refer to a unique address code or port number assigned to each port in a microcomputer system. Further, the port address corresponding to the data packet to be forwarded is determined to obtain a target switching module.

[0056] Furthermore, if the port of the switch module corresponding to the port address is not faulty, the switch module corresponding to the port address will be used as the target switch module; if the port of the switch module corresponding to the port address is faulty, the target backup switch module will be determined from the candidate backup switch modules to replace the target switch module.

[0057] The target switching module's operating status includes whether it is faulty. If the target switching module experiences a power outage or hardware failure, the corresponding gateway will also fail, and the target switching module will be considered faulty. In this case, the target switching module does not meet forwarding conditions and cannot forward the packet.

[0058] Optionally, when the electronic device receives a data packet to be forwarded from any sending end, it establishes a connection with the target switching module and transmits the data packet to be forwarded to the target switching module. When the target switching module fails, the electronic device transmits the data packet to be forwarded to the target backup switching module.

[0059] S103, when it is determined based on the operating status that the target switching module does not meet the forwarding conditions, determine the forwarding performance characteristics of the candidate backup switching module, and determine the target backup switching module from the candidate backup switching modules based on the forwarding performance characteristics; wherein the candidate backup switching module is a switching module in the switching module other than the target switching module.

[0060] The forwarding performance characteristics are the performance characteristics of the candidate backup switching module in forwarding data packets, and may include load capacities such as response time and forwarding rate. The response time indicates how long it takes the candidate backup switching module to begin forwarding data packets; the forwarding rate indicates how long it takes the candidate backup switching module to complete forwarding data packets. The forwarding rate can be determined based on the performance indicators of the candidate backup switching module.

[0061] The other switching modules in the switching module except the target switching module are used as candidate backup switching modules. When the target switching module fails, at least one candidate backup switching module is used to replace the target switching module to forward the data packet to be forwarded.

[0062] Optionally, determining a target backup switching module from the candidate backup switching modules based on the forwarding performance characteristics includes: determining a first backup switching module from the candidate backup switching modules based on the forwarding performance characteristics; when the first backup switching module does not meet the forwarding conditions, determining a second backup switching module from the candidate backup switching modules based on the forwarding performance characteristics; and if the second backup switching module meets the forwarding conditions, determining the second backup switching module as the target backup switching module. By traversing the candidate backup switching modules one by one to determine a reliable target backup switching module, reliable forwarding of data packets is achieved.

[0063] S104: Trigger the target backup switching module to forward the data packet to be forwarded.

[0064] Optionally, after determining the target backup switching module, the target backup switching module is used to replace the target switching module to forward the data packet to be forwarded. While ensuring reliable forwarding of the data packet, it is also forwarded through a high-performance backup switching module to ensure the forwarding efficiency of the data packet.

[0065] Optionally, there may be multiple target backup switching modules; triggering the target backup switching module to forward the data packet to be forwarded includes: determining the number of the target backup switching modules; fragmenting the data packet to be forwarded according to the number of the target backup switching modules to obtain multiple data slices; wherein each data slice carries a corresponding fragmentation sequence; triggering the target backup switching module to forward the multiple data slices respectively, so that the receiving end splices the multiple data slices according to the fragmentation sequence to obtain the data packet to be forwarded.

[0066] In the above embodiment, upon receiving a data packet to be forwarded, the operating status of the target switching module is determined. If the target switching module is determined to be faulty based on the operating status, a target backup switching module is determined from among the candidate backup switching modules based on the forwarding performance characteristics of the candidate backup switching modules, thereby triggering the target backup switching module to forward the data packet to be forwarded. When the target switching module fails, a backup switching module capable of forwarding the data packet is quickly determined, enabling reliable data packet forwarding, reducing data forwarding latency, and ensuring the performance of the entire data forwarding system.

[0067] In one embodiment, the forwarding performance characteristics include a priority; determining the forwarding performance characteristics of the candidate backup switching module and determining the target backup switching module from the candidate backup switching modules based on the forwarding performance characteristics includes: determining the priority of each candidate backup switching module; and determining the candidate backup switching module with the highest priority as the target backup switching module.

[0068] Optionally, determining the priority of each candidate backup switching module includes: obtaining a transmission rate, packet forwarding rate, and backplane bandwidth of each candidate backup switching module; determining a performance indicator value of each candidate backup switching module based on at least one of the transmission rate, packet forwarding rate, and backplane bandwidth; and determining the priority of each candidate backup switching module based on a ranking of the performance indicator values. The performance indicator value may represent the forwarding rate of each candidate backup switching module.

[0069] The transmission rate is the rate at which the switch module forwards data packets. Packet forwarding rate, also known as forwarding rate or throughput, refers to the number of data packets that pass through a unit of time without packet loss. Backplane bandwidth is the maximum amount of data that can be handled between the switch module's interface processor or interface card and the data bus. Backplane bandwidth determines the switch module's data processing capabilities; higher backplane bandwidth indicates greater data processing capabilities.

[0070] Optionally, the performance index value of the candidate backup switching module can be determined based on at least one of the transmission rate, packet forwarding rate, and backplane bandwidth. Further, a weighted sum of the transmission rate, packet forwarding rate, and backplane bandwidth can be calculated and used as the performance index value.

[0071] Optionally, the performance index values ​​may be sorted by size, and the priority of the candidate backup switch module with the highest performance index value may be determined as the highest priority.

[0072] Furthermore, a priority is preset for each backup switching module based on the performance indicators of each switching module. When the target switching module fails, a preferred switching module is selected from the backup switching modules based on the preset priority to forward data packets; wherein the performance indicators include transmission rate, transmission medium, packet forwarding rate, port description, backplane bandwidth, etc.

[0073] This embodiment predetermines the priority of each candidate backup switching module, so that the target backup switching module can be quickly located, thereby achieving rapid forwarding of data packets.

[0074] In one embodiment, the forwarding performance characteristics include a response time; determining the forwarding performance characteristics of the candidate backup switching module and determining the target backup switching module from the candidate backup switching modules based on the forwarding performance characteristics includes: obtaining the response time of each candidate backup switching module; wherein the response time is determined based on at least one of the number of data packets to be forwarded and the transmission rate of the candidate backup switching module; and determining the target backup switching module from the candidate backup switching modules based on the response time.

[0075] Optionally, the number of packets to be forwarded is negatively correlated with the available response time, while the transmission rate is positively correlated with the available response time. Furthermore, the product of the transmission rate and the first coefficient can be divided by the product of the number of packets to be forwarded and the second coefficient, and the available response time of the corresponding backup switching module to be selected can be determined based on the calculated quotient.

[0076] Optionally, the data packets to be forwarded and the transmission rate of each candidate backup switching module are calculated to determine the preferred switching module, such as determining the candidate backup switching module with a small data packet to be forwarded or a short forwarding time as the target backup switching module.

[0077] In this embodiment, the target backup switching module is determined based on the response time, so that the target backup switching module with the fastest response can be determined, and the fast forwarding of the data packets to be forwarded can be realized.

[0078] In one embodiment, the data packets to be forwarded are multiple; the target backup switching module is determined from the backup switching modules according to the forwarding performance characteristics, including: determining the first number of the data packets to be forwarded; determining the target backup switching module corresponding to the first number from the backup switching modules according to the forwarding performance characteristics; and triggering the target backup switching module to forward the data packets to be forwarded, including: triggering the target backup switching module to forward each data packet to be forwarded respectively.

[0079] It should be noted that the data packets to be forwarded can be data packets corresponding to the target switching modules that have failed, that is, if a data packet corresponds to a target switching module that has not failed, it can not be included in the data packets to be forwarded in this embodiment, and can be directly forwarded by the corresponding target switching module. Therefore, the plurality of data packets to be forwarded indicates that a plurality of target switching modules have failed at the same time, and a plurality of target backup switching modules need to be determined to forward the data packets to be forwarded.

[0080] When a plurality of data packets to be forwarded need to be forwarded at the same time, triggering a plurality of target backup switching modules to forward the data packets to be forwarded can ensure the smooth forwarding of the plurality of data packets.

[0081] Further, according to the number of data packets and the preset priority / forwarding performance characteristics of the backup switching modules, the optimal switching modules corresponding to the number are selected from the backup switching modules, and the data packets are forwarded respectively.

[0082] In this embodiment, when a plurality of data packets to be forwarded exist, a corresponding number of backup switching modules are determined, so that the reliable forwarding of the data packets can be ensured, and the efficiency of data forwarding can be ensured.

[0083] Optionally, the target backup switching module can perform parallel forwarding on the data packets to be forwarded.

[0084] In addition to the parallel forwarding mode, the serial forwarding mode can also be implemented. Specifically, in one embodiment, the target backup switching module is triggered to forward the data packets to be forwarded, including: determining the priority of each data packet to be forwarded; and triggering the target backup switching module to forward the corresponding data packet to be forwarded one by one according to the priority of each data packet to be forwarded.

[0085] Optionally, according to the priority order of each data packet, the selected target backup switching module is triggered to forward in sequence.

[0086] By forwarding the data packets to be forwarded one by one, reliable forwarding of the data packets can be ensured without occupying too many backup switching modules.

[0087] In one embodiment, it also includes: determining a second number of the backup switching modules to be selected; fragmenting the data packet to be forwarded according to the second number to obtain multiple data slices; wherein each data slice carries a corresponding fragmentation order; triggering the backup switching modules to be selected to forward the multiple data slices respectively, so that the receiving end splices the multiple data slices according to the fragmentation order to obtain the data packet to be forwarded.

[0088] In this embodiment, the standby backup switching module is directly used to forward the data packet to be forwarded.

[0089] Optionally, the data packet can be fragmented evenly or unevenly. The uneven fragmentation can be implemented by: 1) obtaining the pre-set data forwarding threshold for each candidate backup switching module (the threshold for different candidate backup switching modules may be different), and adaptively fragmenting the data packet according to the data forwarding threshold; 2) determining the current data forwarding volume of each candidate backup switching module and its remaining data forwarding volume, and adaptively fragmenting the data packet according to the remaining data forwarding volume of each candidate backup switching module. Through uneven fragmentation, the currently available candidate backup switching modules can be utilized to the greatest extent possible.

[0090] Optionally, this embodiment can also be implemented in combination with the forwarding performance characteristics of the candidate backup switching modules. For example, sharding is adaptively performed according to the remaining data forwarding volume and forwarding performance characteristics of each candidate backup switching module, and the candidate backup switching modules with good forwarding performance characteristics are given priority. At this time, some of the candidate backup switching modules may not be selected, and the data slices are forwarded through the selected candidate backup switching modules.

[0091] Furthermore, the data is fragmented according to the number of backup switching modules to be selected, and the equally divided data fragments are forwarded by each backup switching module to be selected. The receiving end integrates the data fragments according to the labels on the data fragments (such as the fragmentation order).

[0092] In this embodiment, by fragmenting the data packet, the data packet can be distributed to multiple backup switching modules to forward the data packet, thereby achieving rapid forwarding of the data packet.

[0093] Figure 2 This is an application scenario of a data forwarding method provided by an embodiment of the present invention. Figure 2As shown, this application scenario includes a transmitter 210, a data forwarding system 220, and a receiver 230. The data forwarding system 220 is configured with a switching module group, which includes a target switching module 221 and two candidate backup switching modules 222. It should be noted that in actual application scenarios, the number of candidate backup switching modules may be greater or less.

[0094] Specifically, a transmitting end may refer to a network device for transmitting data packets, and may transmit the data packets to a switching module group in a data forwarding system. This embodiment does not limit the type of transmitting end; for example, the transmitting end may be a digital computer of various forms, such as a laptop computer, a desktop computer, a workstation, a server, a mainframe computer, and other suitable computers. In some embodiments, the transmitting end may transmit data packets to the data forwarding system, which then forwards the data packets to a corresponding receiving end.

[0095] The receiving end may refer to a network device for receiving data packets. This embodiment does not limit the type of the receiving end, as long as it can receive data packets. For example, it may be various forms of digital computers, such as laptop computers, desktop computers, workstations, servers, mainframe computers, and other suitable computers.

[0096] When a target switching module fails, the data forwarding system determines a target backup switching module from the candidate backup switching modules based on the forwarding performance characteristics of the candidate backup switching modules to replace the target switching module in forwarding the data packet to be forwarded.

[0097] Optionally, when receiving a data packet to be forwarded, the data forwarding system determines the operating status of the target switching module. If the target switching module is determined to be faulty based on the operating status, the data forwarding system determines a target backup switching module from the candidate backup switching modules based on the forwarding performance characteristics of the candidate backup switching modules, thereby triggering the target backup switching module to forward the data packet to be forwarded. When the target switching module fails, the data forwarding system quickly determines a backup switching module capable of forwarding the data packet, thereby achieving reliable data packet forwarding, reducing data forwarding latency, and ensuring the performance of the entire data forwarding system.

[0098] Figure 3 FIG. 3 is a structural diagram of a data forwarding device 300 provided in an embodiment of the present invention. Figure 3 As shown, the device includes:

[0099] The data packet receiving module 301 is used to receive data packets to be forwarded;

[0102] The forwarding module 304 is configured to trigger the target backup switching module to forward the data packet to be forwarded.

[0103] In this embodiment, when receiving a data packet to be forwarded, the operating status of the target switching module is determined. If the target switching module is determined to be faulty based on the operating status, a target backup switching module is determined from among the candidate backup switching modules based on their forwarding performance characteristics, triggering the target backup switching module to forward the data packet to be forwarded. When the target switching module fails, a backup switching module capable of forwarding the data packet is quickly determined, enabling reliable data packet forwarding, reducing data forwarding latency, and ensuring the performance of the entire data forwarding system.
