[0001] The present disclosure relates to the technical field of intelligent acceleration network card software, and in particular to a method, apparatus, device and medium for hardware replication of multicast messages. Background Art

[0002] In the multi-queue mode of existing smart network cards, when an application process wants to receive multicast packets for the address it is interested in in the queue, it needs to read them from the default queue. Because multicast is one-to-many, the default queue will contain multicast packets from various applications (APPs). Therefore, when a process receives multicast packets, it will also receive other multicast packets that it is not interested in, resulting in poor multicast packet reception performance. Summary of the Invention

[0003] In order to solve the above technical problems, the present disclosure provides a method, apparatus, device and medium for hardware replication of multicast messages.

[0008] The multicast message is copied to the target queue, so that the application reads the multicast message based on the target queue.

[0020] The hardware multicast message replication method, apparatus, device and medium of the disclosed embodiments can receive the flow table rules issued by the application, and then register the flow table rules to the target address filtering flow table through the FPGA of the hardware layer. Then, in the target address filtering flow table, the received multicast message is queried and processed through the FPGA of the hardware layer to obtain the corresponding target queue.

[0033] In order to solve the above problems, the present disclosure provides a method, device, equipment and medium for hardware replication of multicast messages. Figures 1 to 3 The hardware multicast message replication method provided by the embodiment of the present disclosure is described in detail.

[0034] Figure 1 A flow chart of a method for hardware replication of multicast messages provided in an embodiment of the present disclosure is shown.

[0035] In an embodiment of the present disclosure, the hardware multicast message replication method may be executed by an electronic device, which may include but is not limited to devices such as a computer device, a cloud server, or a cloud server cluster.

[0036] like Figure 1 As shown, the hardware multicast message replication method may include the following steps.

[0037] S110: Receive the flow table rules sent by the application.

[0038] In an embodiment of the present disclosure, the electronic device may receive a flow table rule delivered by an application.

[0039] Optionally, the flow table rule may be a rule related to the sending and receiving of data packets. For example, the flow table rule mainly involves the configuration, viewing method, and management of the flow table. The flow table rule may include the first destination address and the queue identifier.

[0040] Optionally, the first target address may be an address corresponding to an application program. For example, the first target address may be any one of an Internet Protocol (IP) address and a Media Access Control Address (MAC) address.

[0041] Optionally, the queue identifier (Identity document, ID) may be an identifier used to represent a queue number.

[0042] Specifically, the electronic device can receive flow table rules issued by various application programs APP.

[0043] S120 . Register the flow table rule to the target address filtering flow table through the FPGA of the hardware layer.

[0044] In the embodiment of the present disclosure, the electronic device may register the flow table rule to the target address filtering flow table through the FPGA of the hardware layer.

[0045] Alternatively, the hardware layer is the most basic level in a computer system, including all physical components.

[0046] Optionally, a Field Programmable Gate Array (FPGA) can implement the processing of various communication protocols, such as modulation and demodulation in wireless communications, protocol stack implementation, etc.

[0047] Optionally, the destination address filtering flow table may allow a user to filter packets according to predefined rules. The destination address filtering flow table may include multiple queues, each of which may correspond to different user filtering rules.

[0048] Specifically, after receiving the flow table rules sent by the application, the electronic device can register the flow table rules to the target address filtering flow table through the FPGA of the hardware layer, that is, register the flow table rules to the list in the target address filtering flow table.

[0049] S130 , querying and processing the received multicast message in the target address filtering flow table through the FPGA of the hardware layer to obtain a corresponding target queue.

[0050] In the embodiment of the present disclosure, in the target address filtering flow table, the electronic device can query and process the received multicast message through the FPGA of the hardware layer to obtain the corresponding target queue.

[0051] Optionally, the query process may be to determine whether a target queue corresponding to the multicast message exists.

[0052] Optionally, the target queue may be a queue corresponding to the multicast message and used to store the multicast message.

[0053] Specifically, the electronic device can receive a multicast message and query and process the multicast message through the FPGA of the hardware layer, that is, query whether there is a queue corresponding to the multicast message in the target address filtering flow table to obtain the target queue.

[0054] S140: Copy the multicast message to the target queue, so that the application program reads the multicast message based on the target queue.

[0055] In the embodiment of the present disclosure, the electronic device may copy the multicast message to the target queue, so that the application program reads the multicast message based on the target queue.

[0056] Specifically, after obtaining the target queue, the electronic device may copy the multicast message to the target queue. When the user uses an application program to obtain the multicast message, the multicast message may be directly read based on the target queue.

[0057] Therefore, in the embodiment of the present disclosure, it is possible to receive the flow table rules issued by the application, and then register the flow table rules to the target address filtering flow table through the FPGA of the hardware layer, and then in the target address filtering flow table, the received multicast message is queried and processed through the FPGA of the hardware layer to obtain the corresponding target queue, and finally the multicast message is copied to the target queue so that the application can read the multicast message based on the target queue. In this way, the flow table rules issued by the application can be registered to the target address filtering flow table, and after receiving the multicast message, the query processing is performed to obtain the target queue, so that the application can read the multicast message in the target queue, that is, the application only needs to read the multicast message in a specific target queue, and does not need to read other irrelevant messages, thereby improving the efficiency of multicast message reading.

[0058] Optionally, S120 may specifically include: registering, in a target address filtering flow table through the FPGA of the hardware layer, an application queue corresponding to the flow table rule, where the application queue includes the first target address and the queue identifier.

[0059] In the embodiment of the present disclosure, the electronic device may register the application queue corresponding to the flow table rule in the target address filtering flow table through the FPGA of the hardware layer.

[0060] Optionally, the application queue may be a queue for storing flow table rules, wherein the application queue includes the first target address and the queue identifier.

[0061] Specifically, after obtaining the flow table rule, the electronic device can register the application queue corresponding to the flow table rule in the target address filtering flow table through the FPGA of the hardware layer. For example, the flow table rule includes a first target address (IP1, or MAC1) and a queue identifier (ID1). The electronic device can register the application queue corresponding to the flow table rule in the target address filtering flow table, and the application queue includes the first target address (IP1) and the queue identifier (ID1).

[0062] Optionally, before S130, the hardware multicast message replication method may further include: receiving the multicast message; and parsing the multicast message to obtain a corresponding second target address.

[0063] In an embodiment of the present disclosure, an electronic device may receive a data stream, which may include a multicast message.

[0064] Furthermore, the electronic device may parse the multicast message to obtain the corresponding second destination address.

[0065] Optionally, the second destination address may be an address corresponding to the multicast message. The second destination address is similar to the first destination address, and the first destination address may be any one of an IP address and a MAC address.

[0066] Specifically, after receiving the multicast message, the electronic device may parse the multicast message to obtain the corresponding second destination address. For example, the electronic device may parse the header of the multicast message to obtain the corresponding IP address or MAC address, that is, the second destination address.

[0067] Optionally, S130 may specifically include: querying, through the FPGA of the hardware layer, in the target address filtering flow table whether there is the first target address that matches the second target address.

[0068] In an embodiment of the present disclosure, the electronic device may query, through the FPGA of the hardware layer, the target address filtering flow table to determine whether the first target address matches the second target address.

[0069] Specifically, after obtaining the second destination address of the multicast message, the electronic device can query the destination address filtering flow table for the first destination address corresponding to the second destination address, that is, query whether the destination address filtering flow table contains an IP address or MAC address corresponding to the second destination address.

[0070] Optionally, the hardware multicast message replication method may further include: if the first target address matching the second target address exists in the target address filtering flow table, determining that the application queue corresponding to the first target address is the target queue.

[0071] In an embodiment of the present disclosure, if the first target address matching the second target address exists in the target address filtering flow table, the electronic device may determine that the application queue corresponding to the first target address is the target queue.

[0072] Specifically, after the electronic device determines the second target address, if there is the first target address that matches the second target address in the target address filtering flow table, that is, there is an IP address or MAC address that matches the second target address in the target address filtering flow table, then the application queue corresponding to the matching IP address or MAC address can be used as the target queue.

[0073] Optionally, the hardware multicast message replication method may further include: if the first target address matching the second target address does not exist in the target address filtering flow table, determining a default queue as the target queue.

[0074] In an embodiment of the present disclosure, if the first target address matching the second target address does not exist in the target address filtering flow table, the electronic device may determine that a default queue is the target queue.

[0075] Specifically, after the electronic device determines the second target address, if the first target address that matches the second target address does not exist in the target address filtering flow table, that is, the IP address or MAC address that matches the second target address does not exist in the target address filtering flow table, the existing default queue can be used as the target queue.

[0076] Figure 2 A flow chart of a method for hardware replication of multicast messages provided in an embodiment of the present disclosure is shown.

[0077] like Figure 2 As shown, the electronic device can receive the flow table rules issued by each application APP. The flow table rules may include a first target address and a queue identifier. Then, the flow table rules are registered to the target address filtering flow table through the FPGA of the hardware layer, that is, the flow table rules are registered to the list in the target address filtering flow table. For example, the flow table rules include the first target address (IP1, or MAC1) and the queue identifier (ID1). The electronic device can register the application queue corresponding to the flow table rule in the target address filtering flow table. The application queue includes the first target address (IP1) and the queue identifier (ID1).

[0078] Figure 3 A flow chart of a method for hardware replication of multicast messages provided in an embodiment of the present disclosure is shown.

[0079] like Figure 3As shown, after receiving the multicast message, the electronic device can parse the multicast message to obtain the corresponding second target address. For example, the electronic device can parse the header of the multicast message to obtain the corresponding IP address or MAC address, that is, the second target address. Then, the target address filtering flow table is queried for the first target address corresponding to the second target address, that is, the target address filtering flow table is queried for whether the IP address or MAC address corresponding to the second target address exists. In some embodiments, if the first target address that matches the second target address exists in the target address filtering flow table, that is, the IP address or MAC address that matches the second target address exists in the target address filtering flow table, then the application queue corresponding to the matching IP address or MAC address can be used as the target queue. In other embodiments, if the first target address that matches the second target address does not exist in the target address filtering flow table, that is, the IP address or MAC address that matches the second target address does not exist in the target address filtering flow table, then the existing default queue can be used as the target queue.

[0082] The rule receiving module 410 may be configured to receive flow table rules issued by an application.

[0084] The message query module 430 can be used to query the received multicast message in the target address filtering flow table through the FPGA of the hardware layer to obtain the corresponding target queue.

[0085] The message copy module 440 may be configured to copy the multicast message to the target queue, so that the application program reads the multicast message based on the target queue.

[0086] Therefore, in the embodiment of the present disclosure, it is possible to receive the flow table rules issued by the application, and then register the flow table rules to the target address filtering flow table through the FPGA of the hardware layer, and then in the target address filtering flow table, the received multicast message is queried and processed through the FPGA of the hardware layer to obtain the corresponding target queue, and finally the multicast message is copied to the target queue so that the application can read the multicast message based on the target queue. In this way, the flow table rules issued by the application can be registered to the target address filtering flow table, and after receiving the multicast message, the query processing is performed to obtain the target queue, so that the application can read the multicast message in the target queue, that is, the application only needs to read the multicast message in a specific target queue, and does not need to read other irrelevant messages, thereby improving the efficiency of multicast message reading.
