Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Example 1

[0027] This application provides a multimodal network packet processing method. In a first embodiment of this multimodal network packet processing method, it is applied to a multimodal network packet processing system. The multimodal network packet processing system includes a programmable network interface card (NIC), a forwarding engine, and at least one modal virtual network element. (Refer to...) Figure 1 The multimodal network packet processing method includes:

[0028] Step S10: Obtain the set of messages to be processed and the message type of each message to be processed in the set of messages to be processed;

[0029] In this embodiment, it should be noted that the set of messages to be processed is a collection of various messages waiting to be processed. The modal virtual network element runs in a virtual machine manner, and within the virtual machine, computing, storage, and network resources are flexibly allocated according to the network function requirements under different technical systems. The modal virtual network element can be flexibly expanded and elastically loaded and run on demand.

[0030] In one feasible embodiment, the set of packets to be processed is obtained through the programmable network interface card.

[0031] In one feasible embodiment, the packet type of each packet to be processed in the pre-marked set of packets to be processed is obtained through the programmable network interface card.

[0032] In another feasible embodiment, the programmable network interface card (NIC) identifies the message type corresponding to each message to be processed based on the message header of each message to be processed in the message set.

[0033] Step S20: Based on the message type corresponding to each message to be processed, select the processing object corresponding to each message to be processed from the programmable network card, the forwarding engine, and each modal virtual network element;

[0034] In one feasible embodiment, if the message type corresponding to the selected message is a stream data type, then the programmable network interface card (NIC) is used as the processing object corresponding to the selected message.

[0035] In another feasible embodiment, if the packet type corresponding to the selected packet is a general protocol type, then the forwarding engine is used as the processing object corresponding to the selected packet, and the selected packet is forwarded to the forwarding engine through the programmable network card.

[0036] In another feasible embodiment, if the message type corresponding to the selected message is a modal protocol type, then the modal virtual network element corresponding to the modal protocol type is used as the processing object, and the selected message is transmitted to the forwarding engine through the programmable network card, and the selected message is forwarded to the modal virtual network element corresponding to the modal protocol type through the forwarding engine.

[0037] Step S30: By controlling the processing objects corresponding to each of the selected messages to be processed, each message to be processed is processed respectively.

[0038] In one feasible embodiment, based on the message reception time corresponding to each of the messages to be processed, the processing objects corresponding to each of the messages to be processed are selected sequentially by controlling the order of processing, and each message to be processed is processed separately.

[0039] In another feasible embodiment, the programmable network interface card (NIC) is controlled to process the pending packets whose corresponding processing object is the programmable NIC; if it is detected that all pending packets whose corresponding processing object is the programmable NIC have been processed, the forwarding engine is controlled to process the pending packets whose corresponding processing object is the forwarding engine; if it is detected that all pending packets whose corresponding processing object is the forwarding engine have been processed, each modal virtual network element is controlled to process the pending packets whose corresponding processing object is the modal virtual network element.

[0040] In one feasible embodiment, reference is made to Figure 2 , Figure 2 This is a schematic diagram of the structure of a modal virtual network element involved in the multimodal network packet processing method in this application embodiment. The modal virtual network element includes a virtual machine operating system, a system support library, and a modal network service program. The modal network service program flexibly allocates computing, storage, and network resources according to the network function requirements of different modal protocol types, and flexibly processes the packets to be processed to realize the network element functions of different modal protocol types, such as protocol communication, packet forwarding, and content caching. The system support library provides general API (Application Programming Interface) interfaces such as high-performance network packet transmission and reception, high-performance caching, high-performance storage, and flow table distribution to the modal network service program.

[0041] This application provides a multimodal network packet processing method. It involves obtaining a set of packets to be processed and the packet type of each packet in the set; selecting a processing object corresponding to each packet from the programmable network interface card (NIC), the forwarding engine, and each modal virtual network element (VMA) according to the packet type of each packet; and processing each packet by controlling the selected processing object. By integrating the programmable NIC, the forwarding engine, and at least one VMA into a multimodal network packet processing system, multimodal network packet processing with multiple modal protocol types is achieved, reducing the limitations of multimodal network packet processing.

[0042] Example 2

[0043] Furthermore, based on the first embodiment of this application, in another embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, in step S30, the step of processing each of the selected messages by controlling the processing objects corresponding to each message to be processed includes:

[0044] Step S31: Determine the priority of each of the messages to be processed, wherein the priority is used to characterize user needs:

[0045] In one feasible embodiment, the message application type corresponding to each of the messages to be processed and the user's requirements for each message application type are obtained. Based on the message application type corresponding to each of the messages to be processed and the user's requirements for each message application type, a priority corresponding to each of the messages to be processed is generated, wherein the message application type is the purpose type of the message.

[0046] In one feasible embodiment, based on the user's requirements for various message application types, priorities corresponding to each message application type are generated, and the priorities corresponding to the message application types of each message to be processed are used as the priorities corresponding to each message to be processed.

[0047] In another feasible embodiment, before the step of determining the priority corresponding to each of the messages to be processed, wherein the priority is used to characterize user needs, the method further includes: obtaining message fields in each of the messages to be processed, and generating a message application type corresponding to each of the messages to be processed based on the message fields corresponding to each of the messages to be processed.

[0048] Step S32: Select the highest priority message from among the messages to be processed as the target message;

[0049] Step S33: Process the target message by controlling the processing object corresponding to the target message;

[0050] In one feasible embodiment, before the step of processing the target packet by controlling the processing object corresponding to the target packet, the method further includes: placing each of the packets to be processed into a buffer queue in the programmable network card.

[0051] In another feasible embodiment, if the processing object corresponding to the target packet is a forwarding engine, the target packet is retrieved from the cache queue through the programmable network card and sent to the forwarding engine for processing.

[0052] In another feasible embodiment, if the processing object corresponding to the target packet is a modal virtual network element, the target packet is retrieved from the cache queue through the programmable network card and passed to the forwarding engine. The forwarding engine then sends the target packet to the modal virtual network element corresponding to the target packet, and the modal virtual network element corresponding to the target packet processes the target packet.

[0053] In step S33, the step of processing the target message by controlling the processing object corresponding to the target message includes:

[0054] Step A10: Select the target flow table corresponding to the message type of the target message from each preset flow table;

[0055] In this embodiment, it should be noted that each preset flow table includes a flow data flow table, a general protocol flow table, and modal protocol flow tables corresponding to various modal protocol types.

[0056] In one feasible embodiment, if the target packet's packet type is a stream data type, then the stream data flow table is used as the target flow table. The stream data type is not limited here; it can be an IP network stream data type, or other stream data types such as a geographic network stream data type, an identity network stream data type, or an NDN (Named Data Networking) network stream data type.

[0057] In another feasible embodiment, if the message type of the target message is a general protocol type, then the general protocol flow table is used as the target flow table. The general protocol type is not limited here; it can be a network management protocol type, a flow acquisition protocol type, a communication protocol type, or other general protocol types.

[0058] In another feasible embodiment, if the message type of the target message is a modal protocol type, then the modal protocol flow table corresponding to the target message is used as the target flow table. The modal protocol type is not limited here; it can be an IP network modal protocol type, or other modal protocol types such as a geographic network modal protocol type, an identity network modal protocol type, and an NDN network modal protocol type.

[0059] In one feasible embodiment, reference is made to Figure 3 , Figure 3 This is an example diagram illustrating a multimodal network packet processing flow involved in the multimodal network packet processing method described in this application. Figure 3This includes messages of modal protocol type (modal protocol message shown in the figure), messages of stream data type (stream data message shown in the figure), and messages of general protocol type (general protocol message shown in the figure). If the processing object corresponding to the target message is a programmable network interface card (NIC), then the target message is retrieved from the buffer queue through the programmable NIC and processed.

[0060] Step A20: Obtain the matching method corresponding to the target message, and match the message fields in the target message with each preset field in the target flow table according to the matching method to obtain the target field in the target flow table that successfully matches the message fields;

[0061] In one feasible embodiment, before the step of obtaining the matching method corresponding to the target message, the method further includes: obtaining the user's matching requirements for various message fields, and generating the matching method corresponding to each of the messages to be processed according to the matching requirements.

[0062] In one feasible embodiment, the matching method corresponding to the target packet is mask matching. Some fields in the target packet are masked to obtain masked fields. The masked fields are then matched with each preset field in the target flow table to obtain the target fields in the target flow table that successfully match the packet fields.

[0063] In another feasible embodiment, the matching method corresponding to the target message is exact matching, which matches all message fields in the target message with each preset field in the target flow table to obtain the target field in the target flow table that successfully matches the message field.

[0064] Step A30: Control the processing object corresponding to the target packet to process the target packet according to the execution action corresponding to the target field in the target flow table.

[0065] In one feasible embodiment, if the processing object corresponding to the target packet is a programmable network interface card (NIC), then the programmable NIC is controlled to process the target packet according to the execution action corresponding to the target field in the target flow table.

[0066] In another feasible embodiment, if the processing object corresponding to the target packet is a forwarding engine, the target packet and the execution action corresponding to the target field in the target flow table are sent to the forwarding engine through the programmable network card, and the forwarding engine is controlled to process the target packet according to the execution action corresponding to the target field in the target flow table.

[0067] In another feasible embodiment, if the processing object corresponding to the target packet is a modal virtual network element, the programmable network card sends the target packet and the execution action corresponding to the target field in the target flow table to the forwarding engine. The forwarding engine then transmits the target packet and the execution action corresponding to the target field in the target flow table to the modal virtual network element corresponding to the target packet, and controls the modal virtual network element to process the target packet according to the execution action corresponding to the target field in the target flow table.

[0068] In step A30, the step of controlling the processing object corresponding to the target message to process the target message according to the execution action corresponding to the target field in the target flow table includes:

[0069] Step A31: If the action to be performed is a forwarding action, then control the processing object corresponding to the target packet to forward the target packet to the forwarding object corresponding to the forwarding action in the target flow table;

[0070] In this embodiment, it should be noted that the forwarding object can be a port, a forwarding engine, or a modal virtual network element.

[0071] Step A32: If the action to be performed is a modification action, then according to the modification field and modification method corresponding to the modification action in the target flow table, control the processing object corresponding to the target packet to modify the packet field in the target packet;

[0072] In one feasible embodiment, if the modification method is an addition, the processing object corresponding to the target packet is controlled to add the modification field corresponding to the modification action in the target flow table to the target packet.

[0073] In another feasible embodiment, if the modification method is deletion, the processing object corresponding to the target packet is controlled to delete the deletion field in the target packet, and the deletion field is the modification field corresponding to the modification action in the target flow table.

[0074] In another feasible embodiment, if the modification method is replacement, then the processing object corresponding to the target packet is controlled to replace the packet field in the target packet with the modification field corresponding to the modification action in the target flow table.

[0075] Step A33: If the action to be performed is a discard action, then control the processing object corresponding to the target packet to discard the target packet.

[0076] In step A30, the step of controlling the processing object corresponding to the target message to process the target message according to the execution action corresponding to the target field in the target flow table includes:

[0077] Step B10: If the packet type of the target packet is a modal protocol type, the target packet is transmitted to the forwarding engine through the programmable network card, the forwarding engine forwards the target packet to the modal virtual network element corresponding to the modal protocol type, and the modal virtual network element processes the target packet according to the execution action corresponding to the target field.

[0078] Step S34: Return to the step of selecting the highest priority message among the messages to be processed as the target message, until all the messages to be processed have been processed.

[0079] In this embodiment, by determining the priority of each of the pending messages, where the priority is used to characterize user needs; selecting the message with the highest priority among the pending messages as the target message; processing the target message by controlling the processing object corresponding to the target message; returning to the step of selecting the message with the highest priority among the pending messages as the target message, until all pending messages have been processed. Since priority can characterize user needs, that is, the greater the user's need for pending messages, the higher the priority of the pending message, the higher the priority of the pending message. Processing the message with the highest priority among the pending messages first achieves multimodal network message processing that meets user needs.

[0080] In step S20, before the step of selecting the processing object corresponding to each of the packets to be processed from the programmable network interface card, the forwarding engine, and each of the modal virtual network elements according to the packet type corresponding to each of the packets to be processed, the method further includes:

[0081] Step C10: Obtain messages of each modal protocol type, where each message belongs to a modal protocol type and corresponds to a network function requirement;

[0082] Step C10: Based on the messages of each modal protocol type, the modal protocol type corresponding to each message of each modal protocol type, and the network function requirements corresponding to each message of each modal protocol type, construct the modal virtual network element corresponding to each message of each modal protocol type.

[0083] Optionally, in addition to supporting ordinary network card packet transmission and reception, the programmable network interface card (NIC) in this application must also be able to support the mixed operation of multiple network technologies by multi-modal network element nodes, and forward network packets of multiple different technologies in real time. (See reference...) Figure 4 , Figure 4 This is a schematic diagram of the structure of a programmable network interface card (NIC) involved in the multimodal network packet processing method of this application. The programmable NIC includes a control unit, a switching unit, a forwarding flow table, and a packet buffer queue. The control unit communicates with external systems (including servers and adjacent NICs) through a PCIe interface. It stores the flow table issued by the server in the forwarding flow table according to the modal type, stores packets sent by the server or adjacent NICs in the sending buffer queue, and sends packets in the receiving buffer queue to the server or adjacent NICs. The switching unit implements multi-port packet forwarding and processing. After receiving packets from the network port, it parses and matches the packets according to the table entries in the forwarding flow table, and performs modification, discarding, or forwarding actions. Packets that need to be sent to the server or adjacent NICs are stored in the receiving buffer queue, while packets in the sending buffer queue are sent to the network. To support the forwarding and processing of network packets from various technical systems, the network interface card (NIC) described in this patent contains multiple forwarding flow tables. Each flow table stores entries for different technical systems, and each entry contains multiple matching fields and multiple action fields. After receiving a packet, the NIC parses it according to the matching fields of the flow table entry and executes the actions in the action fields, including dropping, forwarding, and modifying. To enable the mixed operation of various technical systems without interference, achieving coexistence and isolation between different technical systems, the NIC described in this patent contains multiple packet receiving and sending buffer queues for receiving and sending packets with virtual network elements under different technical systems. Simultaneously, it directly communicates with external NICs via DMA, enabling direct access and exchange of packets with external NICs without going through a server, thus improving packet forwarding performance.

[0084] This application provides a multimodal network packet processing method. It acquires packets of various modal protocol types, where each packet belongs to a specific modal protocol type and corresponds to a specific network functional requirement of a technical system. Based on the packets of each modal protocol type, the corresponding modal protocol type for each packet, and the corresponding network functional requirement of each modal protocol type, it constructs modal virtual network elements corresponding to each of the aforementioned modal protocol types. By constructing modal virtual network elements of various modal protocol types, multimodal network packet processing of multiple modal protocol types can be achieved, reducing the limitations of multimodal network packet processing.

[0099] Optionally, the processing module is further configured to:

[0100] If the target packet is a modal protocol type, the target packet is transmitted to the forwarding engine through the programmable network interface card (NIC), and the forwarding engine forwards the target packet to the modal virtual network element corresponding to the modal protocol type. The modal virtual network element then processes the target packet according to the execution action corresponding to the target field.
