[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] In the prior art, when "data center 1 sends a message to data center 2", it essentially executes the operation of "moving a piece of data in the memory of data center 1 to the memory of data center 2 with the help of a network link". In this process, both the sending and receiving ends of the data are inseparable from the command and control of the CPU. Tasks such as controlling the network card, handling interrupts, and encapsulating and parsing messages are all the responsibility of the CPU.

[0053] Specifically, if data center 1 (providing computing services) wants to send data in the memory user space, the CPU must first copy it to the buffer in the kernel space. Only in this way can the data be accessed by the network card. During the copying process, the data will pass through the TCP / IP protocol stack implemented by software. The protocol stack will add headers and checksums of each layer to the data. Then, the network card copies the data in the kernel to its own internal buffer. After corresponding processing, the data is sent to the peer data center through a physical link. After receiving the data, the peer will follow the reverse process. First, the data is copied from the internal storage space of the network card to the buffer in the memory kernel space. Then, the CPU will use the TCP / IP protocol stack to parse the data, extract the data from it, and copy it to the user space.

[0054] At present, the realization of the above technologies depends on the support of high-speed interconnection buses, high-speed networks and other channels. However, the CPU has a huge overhead when processing interruptions of high-speed channels. The supercomputing service carrier data will be repeatedly copied in the kernel space, which causes it to be "worn out" and prolongs the usage time of the computing data. If the amount of data is large, then for a long time, the CPU will be busy moving data and will have no time to take care of other work. However, the CPU's main task should be calculation, not data copying. This kind of data moving work actually wastes the CPU's computing power and reduces transmission efficiency.

[0055] One of the core concepts of the embodiments of the present invention is that after the local data center establishes a communication connection with the opposite data center, the present invention can obtain business data from the local memory through the processing unit, encapsulate it into a data packet, and send it to the opposite data center through the network card. At the same time, it can also receive data packets sent by the opposite data center, thereby realizing data interaction between the two data centers, breaking the geographical limitations of data, facilitating different data centers to share each other's business data, and improving overall business efficiency; the entire process of business data transmission of the present invention does not require the central processing unit to process data, which can reduce the burden on the central processing unit, realize effective data protection in the network, and provide customers with safe and reliable services.

[0056] Reference Figure 1 , shows a flow chart of the steps of a data center data transmission method provided by an embodiment of the present invention, the data center includes a memory, a network card and a processing unit, and the method may include the following steps:

[0057] Step 101, after a communication connection is established between a local data center and a peer data center, a local processing unit obtains first service data from a local memory and encapsulates the first service data into a first data packet.

[0058] In an embodiment of the present invention, before the local data center and the opposite data center transmit data, the local data center and the opposite data center need to first establish a stable communication connection, which is usually achieved through network equipment (such as routers, switches) and communication protocols. After the communication connection is established, data can be transmitted between the two data centers. It should be noted that the specific communication protocol can be set according to user needs, and can be an Internet communication protocol or a visual network communication protocol.

[0059] The local processing unit is the core component responsible for data processing. It can read data from the local memory. The local processing unit can be a DPU processor. The data may be user information, transaction records, log information, supercomputing service data, etc., depending on the business scenario.

[0060] After the local processing unit obtains the first service data, the local processing unit will encapsulate the data into a data packet. The data packet is the basic unit of network communication. It contains the data itself and some additional information. The structure of the data packet may include header information and payload (including actual data). The header information is used to control the transmission and processing of data, while the payload is the actual data that needs to be transmitted.

[0061] Step 102: Send a first data packet to the peer network card through the local network card, so that the peer data processing unit obtains the first data packet from the peer network card and writes the first service data parsed from the first data packet into the peer memory.

[0062] In an embodiment of the present invention, after obtaining the encapsulated first data packet, the local network card will send it to the opposite network card through a pre-established network link according to pre-set communication rules and network protocols. This sending process is performed on the basis of the established communication connection between the local data center and the opposite data center. Then, the opposite processing unit can obtain the first data packet from the opposite network card, analyze and process the various components of the first data packet according to the communication protocol specification followed when the data packet is encapsulated, and extract the first business data contained therein, for example, remove the source address, destination address, check code and other parts used for transmission control in the packet header, accurately restore the original first business data, and then write it into the opposite memory.

[0063] Step 103: Receive the second data packet sent by the peer network card through the local network card, obtain the second data packet from the local network card through the local data processing unit, parse the second data packet to obtain second service data, and write the second service data into the local memory.

[0064] In the embodiment of the present invention, the first data center can also receive the second data packet sent by the opposite network card through the local network card, because the second data packet is obtained by the opposite processing unit encapsulating the second service data according to the preset communication rules and network protocol.

[0065] The second data packet can be parsed according to the communication protocol previously agreed upon by both parties, for example, the source address (clearly sent from the other end's data center), destination address (confirmed to be the local data center), data length, checksum and other information contained in the header of the second data packet can be identified, and then these "outer packaging" used for transmission security can be removed to accurately extract the second business data.

[0066] After the local data center establishes a communication connection with the opposite data center, the present invention can obtain business data from the local memory through the protocol data processing unit, encapsulate it into a data packet, and send it to the opposite end through the network card. At the same time, it can also receive the data packet sent by the opposite end, thereby realizing data interaction between the data centers at both ends, breaking the geographical limitation of data, facilitating different data centers to share each other's business data, and improving overall business efficiency; the present invention does not require the central processing unit to process data throughout the data transmission process, which can reduce the burden on the central processing unit, realize effective data protection in the network, and provide customers with safe and reliable services.

[0067] Reference Figure 2 , shows a flowchart of another data center data transmission method provided by an embodiment of the present invention, the data center includes a memory, a network card and a processing unit, and the method may include the following steps:

[0068] Step 201, read the MAC address of the local network card through the local processing unit, and register the MAC address of the local network card in the visual network communication protocol service to obtain the visual network communication address of the local network card.

[0069] In the embodiment of the present invention, the MAC address is a unique identifier of the network card, just like everyone has a unique ID number, and it is used to distinguish and identify devices in a network environment.

[0070] After obtaining the MAC address of the local network card, the local protocol data processing unit will register it to the visual network communication protocol service. The visual network communication protocol service is like a "steward" who manages network communication identities. It receives and processes the MAC address information of the local network card, and assigns a specific visual network communication address to the local network card through corresponding rules and calculations.

[0071] In one embodiment of the present invention, the data center also includes a controller, which reads the MAC address of the local network card through the local processing unit, and registers the MAC address of the local network card in the visual network communication protocol service to obtain the visual network communication address of the local network card, including: sending a control instruction to the local processing unit through the local controller, so that the local processing unit reads the MAC address of the local network card, and registers the MAC address of the local network card in the visual network communication protocol service to obtain the visual network communication address of the local network card.

[0072] In an embodiment of the present invention, the controller will generate corresponding control instructions based on pre-set rules and requirements, and then the control instructions will be sent to the processing unit. After the processing unit DPU receives the instructions from the controller, it starts to execute the corresponding operation. Its operation specifically includes two aspects. On the one hand, it will read the MAC address of the local network card. This reading process is to accurately locate the local network card along the links and related interfaces within the data center and obtain its MAC address information. This MAC address is the inherent identification of the local network card at the basic network level.

[0073] On the other hand, after obtaining the MAC address of the local network card, the processing unit will further register the MAC address to the visual network communication protocol service. The visual network communication protocol service is like a "big platform" for managing network communication identities. After receiving the MAC address from the local network card, it will assign it a visual network communication address that is exclusive to the local network card in accordance with its own established set of mechanisms and algorithms. This address can subsequently be used to accurately identify the local network card in the visual network environment, and participate in various activities such as communication interactions with other devices and data centers.

[0074] Step 202, obtain the visual network communication address of the opposite network card through the local processing unit, and establish a visual network communication connection between the local data center and the opposite data center based on the visual network communication address of the local network card and the visual network communication address of the opposite network card.

[0075] In an embodiment of the present invention, when the local protocol data processing unit has obtained the visual networking communication address of the local network card and the visual networking communication address of the opposite network card, a visual networking communication link can be established between the local data center and the opposite data center based on these two addresses, so that the local data center can communicate with the opposite data based on the visual networking communication link. The present invention can accurately give each network card an exclusive communication identifier in the visual networking environment, and equip them with a unique "communication business card", so that the data centers can smoothly build a visual networking communication connection based on these accurate addresses, ensuring that the visual networking communication is carried out efficiently, orderly and stably, effectively realizing the accurate transmission and interaction of data, and meeting the diverse business application needs.

[0076] Step 203, after the local data center establishes a communication connection with the opposite data center, the local processing unit obtains the first service data from the local memory and encapsulates the first service data into a first data packet.

[0077] In one embodiment of the present invention, the first data packet is a first visual networking data packet, and the processing unit includes a socket tool, which encapsulates the first business data into the first data packet, including: encapsulating the first data packet according to the first business data through the local socket tool.

[0078] In one embodiment of the present invention, the first business data is supercomputing service data.

[0079] In an embodiment of the present invention, the first business data and the second business data may be supercomputing service data, which refers to various data and information related to different types of computing tasks such as scientific computing, engineering simulation, big data analysis, and artificial intelligence training.

[0080] In the DPU, the socket tool plays an important role. When the first service data needs to be encapsulated into the first visual network data packet, the following process is followed:

[0081] After the protocol data processing unit obtains the first business data, the socket tool on this end starts to function. It will perform a series of information addition operations on the packet header part of the first business data, just like attaching various important labels to a package. These labels can help accurately identify and process the data in subsequent transmission, reception and processing links.

[0082] Specifically, information related to the visual network communication protocol will be added, which is equivalent to stipulating the "traffic rules" that this data packet needs to follow when transmitting in the visual network, ensuring that it can pass smoothly in accordance with the established communication method of the visual network; then the data length information will be added, through which the receiver can know the size of the data packet in advance, facilitating subsequent accurate reception and integrity verification; business type information will be added, which allows the receiver to quickly determine the specific category of the business carried by the data packet, so as to adopt the corresponding business processing flow; finally, data source information will be added so that the receiver knows clearly where the data is sent from, which is convenient for tracing the source and performing some targeted interactive feedback and other operations.

[0083] After the socket tool adds the above key header information to the header of the first business data packet, a complete first visual Internet data packet is obtained. This data packet has all the conditions for accurate transmission, correct identification and processing according to the corresponding business process in the visual Internet environment, and can better serve the subsequent visual Internet communication and business development needs.

[0084] In one embodiment of the present invention, the local processing unit includes a register, and the first business data is obtained from the local memory through the local processing unit, and the first business data is encapsulated into a first data packet, including: obtaining the first business data from the local memory through the local processing unit, and storing the first business data in the register; encapsulating the first business data in the register into a first data packet.

[0085] In an embodiment of the present invention, in the local memory, data is classified and stored according to different business identifiers. The local processing unit must first clarify the business identifier corresponding to the first business data to be obtained, and query the corresponding storage area according to the business identifier. After locating the corresponding storage area, the local processing unit uses the connection path between it and the local memory (usually through a data bus, etc. to realize data transmission) to read the first business data from the memory according to the preset reading rules and signal protocols.

[0086] The local processing unit contains multiple registers, and different registers may have different uses or be in different working states. The processing unit will select a suitable register to store the first business data according to the current data processing requirements and the internal resource allocation strategy. For example, some registers may be used specifically for temporarily storing data that is about to be packaged, and the first business data read from the memory will be stored in such registers;

[0087] Furthermore, the processing unit can encapsulate the first business data stored in the register. First, it will add header information. The header part contains many important metadata, which is used to identify, route and verify the data packet in the subsequent data transmission process. For example, source address information will be added to indicate that the data packet is sent from the local data center; destination address information clearly specifies the address of the opposite data center or specific receiving module to which the data packet is to be sent; data length information will also be added to let the recipient know the size of the data packet in advance, which is convenient for it to verify the receiving integrity; and information such as the check code is used by the recipient to verify whether there are any errors in the data transmission process.

[0088] After adding the header information, the processing unit will assemble the first service data in the register with the header information according to the established data packet structure specification to form a complete first data packet.

[0089] Step 204: Send a first data packet to the peer network card through the local network card, so that the peer data processing unit obtains the first data packet from the peer network card and writes the first service data parsed from the first data packet into the peer memory.

[0090] Step 205: Receive the second data packet sent by the peer network card through the local network card, obtain the second data packet from the local network card through the local data processing unit, parse the second data packet to obtain second service data, and write the second service data into the local memory.

[0091] In one embodiment of the present invention, the second data packet is a second visual network data packet, the second data packet is parsed to obtain second business data, and the second business data is written into the local memory, including: parsing the second data packet through the local socket tool to obtain the second business data; writing the second business data into the local memory.

[0092] In an embodiment of the present invention, when the second data packet is a second visual networking data packet, the second visual networking data packet can be parsed by the local socket tool to obtain the header information and second business data of the second data packet. The header information may include the visual networking communication protocol, destination address, data type, and source address. Then, the second business data can be written to the corresponding position of the local memory according to the destination address, thereby achieving accurate writing.

[0093] In an embodiment of the present invention, the local memory further includes service data corresponding to different service identifiers, and obtaining the first service data from the local memory by the local processing unit includes:

[0094] The first service identifier is obtained through the local processing unit, and the corresponding first service data is searched in the local memory according to the first service identifier.

[0095] In an embodiment of the present invention, the local memory can store business data corresponding to different business identifiers, for example, identifier A corresponds to the first type of supercomputing service data, identifier B corresponds to the second type of supercomputing service data, and identifier C corresponds to the third type of supercomputing service data. The local protocol data processing unit can first obtain the first business identifier, and after obtaining the first business identifier, the corresponding first business data can be queried in the correspondence between the identifier and the business data in the local memory according to the first identifier. With the help of the obtained business identifier, the local protocol data processing unit can accurately query and obtain the corresponding first business data in the local memory storing various types of business data, thereby serving the business processes and functional requirements of different systems.

[0096] After the local data center establishes a communication connection with the opposite data center, the present invention can obtain business data from the local memory through the processing unit, encapsulate it into a data packet, and send it to the opposite data center through the network card. At the same time, it can also receive data packets sent by the opposite data center, thereby realizing data interaction between the two data centers, breaking the geographical limitation of data, facilitating different data centers to share each other's business data, and improving overall business efficiency; the entire process of business data transmission of the present invention does not require the central processing unit to process data, which can reduce the burden on the central processing unit, realize effective data protection in the network, and provide customers with safe and reliable services.
