Referring to fig. 4, fig. 4 is a schematic flowchart of a quotation snapshot distributing method applied to a quotation server according to an embodiment of the present application. The method is applied to a market server of a comprehensive service system of a trading exchange, the comprehensive service system of the trading exchange comprises the market server and at least one high-frequency trading terminal, the market server comprises a host CPU and DPUs, the host CPU of the market server is provided with a plurality of market cloud service hosts, the host CPU of the market server corresponds to each market cloud service host and stores different types of market snapshots, each type of market snapshot comprises market information of different target products, and the DPUs of the market server are provided with vDPUs corresponding to the market cloud service hosts one to one. The vDPU can correspondingly allocate exclusive data processing resources for the market cloud service host, so that market snapshot distribution tasks originally completed by a host CPU of the market server are borne by the DPU, the computing power of the CPU is released to realize tasks of an application layer, and the computing efficiency of the market server is improved.

The market snapshot distribution method shown in fig. 4 can be applied to the market server in the exchange integrated service system described in any one of fig. 1 to 3. As shown in fig. 4, the market snapshot distribution method includes:

step S110, the target processing module of the processing chip obtains a target market snapshot in a first storage space of a host CPU of the market server, and caches the target market snapshot in a second storage space of a DPU of the market server.

The target processing module is one of a plurality of processing modules of which a plurality of vDPUs are deployed on a processing chip. For example, referring to fig. 3, the target processing module may be the processing module 1, and the target market quotation snapshot obtained by the processing module 1 is a market quotation snapshot stored by a host CPU of the market quotation server and corresponding to the market quotation cloud service host 1.

Wherein one market snapshot comprises market information of one target product. A host CPU of the market information server is provided with a first storage space corresponding to each market information cloud service host. Specifically, one market cloud service host may correspond to a market snapshot of one target product, or may also correspond to market snapshots of multiple target products, which may be specifically set according to needs, and is not limited herein. When a market cloud service host correspondingly generates market snapshots of a plurality of target products, the target market snapshot acquired by the target processing module of the processing chip may be a market snapshot of one of the target products. For convenience of description, the following description will be given by taking an example in which a market cloud service host correspondingly generates a market snapshot.

The first storage space is a storage position which is provided by a host CPU of the market server and corresponds to each market cloud service host, and the second storage space is a storage position which is provided by a host DPU of the market server and corresponds to market snapshots which are obtained by all vDPUs. The host CPU of the quotation server can divide the memory space of the quotation cloud service host into a plurality of first memory spaces corresponding to the quotation cloud service hosts, and all the quotation snapshots correspondingly generated by one quotation cloud service host are stored in the first memory space corresponding to the quotation cloud service host. The DPU of the market conditions server may also divide the memory space of each vDPU into a plurality of second memory spaces corresponding to the DPUs, and a market conditions snapshot obtained by one vDPU from the market conditions cloud service host corresponding to the DPU is stored in one second memory space corresponding to the DPU. Namely, one first storage space, one second storage space and one market cloud service host are configured in a one-to-one correspondence manner.

In specific implementation, a first storage space corresponding to one market cloud service host may store a market snapshot of a target product. At this time, the high-frequency transaction terminal and the market cloud service host can adopt a one-to-many form. That is, if the high-frequency trading terminal subscribes to at least two target products, the market snapshot sent by the vDPU corresponding to all the target products subscribed to the high-frequency trading terminal can be received. For example, referring to fig. 2, the market cloud service host 1 may generate a market snapshot 1, the market cloud service host 2 may generate a market snapshot 2, and the market cloud service host 3 may generate a market snapshot 3. The high-frequency trading terminal 200a subscribes to the target products corresponding to the market snapshot 1 and the market snapshot 2, so that the high-frequency trading terminal 200a can receive the market snapshot 1 and the market snapshot 2 from the vDPU1 and the vDPU2, respectively. In this example, the host CPU and the DPU of the market conditions server may implement data isolation in the process of performing data interaction between each market conditions cloud service host and the corresponding vDPU, and ensure the accuracy of data processing by the host CPU and the DPU of the market conditions server, thereby ensuring the accuracy of market conditions information transmitted to the high-frequency transaction terminal.

In specific implementation, the quotation snapshot can be generated by the processing of a host CPU of the quotation server, and the distribution work of the quotation snapshot is completed through a DPU of the quotation server. Or, the quotation snapshot can unload the updating calculation function when the quotation snapshot is generated to the DPU, and the DPU completes the calculation work of the transaction amount, the total transaction amount and other information of the transaction delegation, so that the processing pressure of the CPU of the host computer is further reduced, and the efficiency of the quotation server for generating the quotation snapshot is improved. In a specific implementation, when the update calculation function when generating the market snapshot is completed by the DPU of the market server, the DPU of the market server may send a calculation result of market snapshot update data to the host CPU of the market server, and the host CPU integrates the market snapshot update data with the historical market snapshot, so as to generate an updated market snapshot and store the updated market snapshot in the corresponding first storage space. The target market quotation snapshot acquired by the target processing module of the processing chip is an updated market quotation snapshot.

Specifically, in the process that the quotation snapshot unloads the updating calculation function when the quotation snapshot is generated to the DPU, the quotation cloud service host and the vDPU also perform data processing by adopting a one-to-one correspondence relationship so as to realize data isolation.

And step S120, a target processing module of the processing chip processes the target market quotation snapshot to obtain a market quotation broadcast message.

The processed market broadcast message meets the data form requirement of the market server to distribute to the high-frequency transaction terminal.

Step S130, the target processing module of the processing chip sends the market information broadcast message to a target high-frequency transaction terminal by using a switch network.

The target high-frequency trading terminal is a device which is added into a market situation multicast group of the market situation server, and the target high-frequency trading terminal is a device which subscribes a target product corresponding to the target market situation snapshot.

The target high-frequency transaction terminal can be at least one high-frequency transaction terminal which is in communication connection with the market server in the exchange integrated service system.

In specific implementation, the target high-frequency trading terminal can receive the target market snapshot issued by the market server, so that a user can know market information of a target product in real time through the target high-frequency trading terminal and can offer a purchase price or a sell price to buy or sell the target product according to the received market information, and trading requirements of the user are met.

It can be seen that, in this embodiment, a target processing module of the processing chip may first obtain a target market snapshot in a first storage space of a host CPU of the market server, and cache the target market snapshot in a second storage space of a DPU of the market server; then the target processing module of the processing chip processes the target market quotation snapshot to obtain market quotation broadcast messages; and finally, a target processing module of the processing chip sends the market broadcast message to a target high-frequency transaction terminal by using a switch network. Therefore, the quotation snapshot distribution function executed by the host CPU of the quotation server can be unloaded to the DPU for execution, so that the processing pressure of the host CPU is favorably reduced, and the calculation efficiency of the quotation server is improved.

In one possible example, a target processing module of the processing chip obtains a target market snapshot in a first storage space of a host CPU of the market server and caches the target market snapshot in a second storage space of a DPU of the market server, including: a target processing module of the processing chip receives descriptor information from a host CPU of the market server, wherein the descriptor information comprises message length information and memory address information of the target market snapshot; the target processing module of the processing chip transparently transmits the descriptor information to the control chip; and under the condition that a target processing module of the processing chip receives a Direct Memory Access (DMA) request sent by a target control module of the control chip according to the descriptor information, copying the line target market snapshot from a first storage space of a host Central Processing Unit (CPU) of the market server to a second storage space of a Data Processing Unit (DPU) of the market server by using a DMA technology, wherein the Direct Memory Access (DMA) request is used for requesting to acquire the target market snapshot corresponding to the descriptor information in the first storage space by using the DMA technology.

The descriptor information comprises information such as message length and memory address corresponding to the target market condition snapshot, and is used for indicating the storage position, data size and the like of the target market condition snapshot.

In a specific implementation, the host CPU of the market server can run a host CPU driver stack of the market server, and the host CPU driver stack of the market server provides a file system and a TCP/IP protocol stack. Before a host CPU of the market server informs a DPU of the market server to acquire a target market snapshot by using a DMA technology, the host CPU of the market snapshot can run a TCP/IP protocol stack and call a TCPSocket (socket) interface, so that a virtual-network driver (network card drive) is called through the TCP/IP protocol stack to write descriptor information of the market snapshot through a PCIe (peripheral component interconnect express) interface. The PCIe interface is a communication interface of a host CPU of the market server and a DPU of the market server. After the host CPU of the market server writes the descriptor information, the processing chip of the DPU of the market server transmits the descriptor information to the control chip. And the control chip calls the processing chip again according to the read content of the descriptor information, so that the processing chip executes the DMA operation through a PCIe interface connected between the DPU of the market server and the host CPU of the market server, and the market snapshot in the first storage space of the host CPU is copied to the second storage space of the DPU.

In a specific implementation, the host CPU of the market server may write the descriptor of the market snapshot periodically, for example, the host CPU of the market server may write the descriptor every 0.3 second or 0.5 second, so that the DPU of the market server can periodically obtain all market snapshots and distribute the market snapshots to the corresponding high-frequency trading terminals according to the subscription condition of the high-frequency trading terminals. Or the host CPU of the market server can write the descriptor after updating the market snapshot every time, so that the DPU of the market server can distribute market information to the high-frequency transaction terminal in time, a user can know market information of a target product in time, and user experience is improved.

In a specific implementation, the host CPU of the market server may further send a notification to the processing chip after writing the descriptor information, where the notification is used to indicate that the information written by the host CPU of the market server through the PCIe interface is the descriptor information of the market snapshot. When the processing chip receives the notice, the descriptor information is directly transmitted to the control chip.

Further, the control chip may send the DMA request to the processing chip by writing a register, where the register is a register shared by all control modules in the control chip. The register may be configured to store DMA request command information, where the DMA request command information may include a start address required for DMA, a destination address of the DMA, a DMA direction, and a length occupied by contents copied by the DMA. The starting address of the DMA is memory address information of a target market snapshot obtained by analyzing the descriptor information by the control chip, the destination address of the DMA is a second storage space position corresponding to the target market snapshot, the DMA direction of a direct memory access DMA request sent by the register is to copy the target market snapshot from the first storage space to the corresponding second storage space, and the length occupied by the copied content of the DMA is the message length information of the target market snapshot obtained by analyzing the descriptor information by the control chip. After the control chip writes the relevant content of the direct memory access DMA request in the register, the control chip determines to send the direct memory access DMA request to the processing chip, so that the processing chip can utilize the DMA engine to carry out DMA. According to the application, the market conditions snapshot of a target product is correspondingly stored in the first storage space, so that which market conditions cloud service host in the current host CPU is driving to use the DPU can be determined according to the memory address information of the target market conditions snapshot in the descriptor information, and the acquisition and distribution of the target market conditions snapshot can be realized.

In this embodiment, the DPU of the market server directly obtains the target market snapshot from the first storage space of the CPU of the market server by using the DMA technology through the processing chip, which can reduce the participation of the host CPU of the market server in the process of obtaining the target market snapshot by the DPU of the market server, so that the host CPU of the market server can perform other work in the process of obtaining the market snapshot by the DPU of the market server, thereby improving the work efficiency of the market server.

In one possible example, referring to fig. 3 and 5, the processing chip includes a snapshot transmission module and a message processing module, and the snapshot transmission module includes a transmission processing module, a message caching module, and a message editing module; the target processing module of the processing chip processes the target market snapshot to obtain market broadcast messages, and the process comprises the following steps: a target processing module of the processing chip acquires the target market snapshot from a second storage space of a DPU of the market server through the transmission processing module, and judges whether the target market snapshot needs to be subjected to accelerated processing of a transmission layer or not according to the type of the target market snapshot through the transmission processing module; if so, the target processing module of the processing chip executes accelerated transmission processing operation corresponding to the type of the target market snapshot on the target market snapshot through the transmission processing module; if not, the target processing module of the processing chip executes general transmission processing operation corresponding to the type of the target market snapshot on the target market snapshot through the transmission processing module; a target processing module of the processing chip acquires the transmitted and processed target market snapshot through the message caching module and caches the transmitted and processed target market snapshot; the target processing module of the processing chip acquires the target market quotation snapshot after the transmission processing, which is cached by the message caching module, through the message processing module, and analyzes the target market quotation snapshot after the transmission processing through the message processing module to obtain the execution action information of the target market quotation after the transmission processing; and the target processing module of the processing chip encapsulates the transmitted and processed target quotation according to the execution action information through a message editing module to obtain a quotation broadcast message.

In specific implementation, the transmission processing module is configured to perform transport layer protocol processing to determine whether the transmitted target market snapshot needs to be accelerated. Specifically, the target processing module of the target processing chip may first obtain the target market snapshot to be transmitted from the corresponding second storage space through the transmission processing module, and then determine whether the target market snapshot needs to be accelerated by the transmission layer according to the type of the target market snapshot. The market quotation cloud service host and the types of the target market quotation snapshots correspond to each other one by one, so that the types of the target market quotation snapshots can be obtained according to the positions of the first storage spaces for obtaining the target market quotation snapshots.

In specific implementation, the process that a target processing module of a processing chip judges whether the target market snapshot needs to be subjected to transport layer accelerated processing or not according to the type of the target market snapshot through the transmission processing module is as follows: the target processing module of the processing chip judges whether the quotation snapshot is in a RoCE (remote direct memory access based on converged Ethernet) format or not through the transmission processing module, if so, the RDMA processing flow is directly executed on the target quotation snapshot through an RDMA (remote direct memory access) technology, so that the target high-frequency transaction terminal directly obtains the target quotation snapshot to achieve an acceleration effect. For example, the quotation snapshot generated by the quotation cloud service host 1 may be preset in a RoCE format, so when the target quotation snapshot received by the transmission processing module is from the quotation cloud service host 1, it is directly determined that the target quotation snapshot needs to be processed in an accelerated manner by an RDMA technology. And if the target processing module of the processing chip judges that the target quotation snapshot acquired by the quotation snapshot is not in the RoCE format through the transmission processing module, transmitting the target quotation snapshot according to a general processing flow. Illustratively, if the target market snapshot received by the transmission processing module is not in the RoCE format, the transmission processing module may perform IP/TCP/UDP packet acceleration processing on the market snapshot. For example, processing operations such as IP/TCP/UDPCheckSum (checksum) calculation, TCP/UDP packet slicing, etc. may be performed on the packet of the target market snapshot.

In a specific implementation, the target market snapshot stored in the second storage space is obtained from the first storage space through the PCIe interface broadband, and is inconsistent with the ethernet broadband used for distribution. In practical application, when a plurality of target market snapshot from a plurality of market cloud service hosts are synchronously distributed, distribution processing needs to be performed according to priority, so that a message caching module needs to be used for caching in the transmission process of the market snapshot to ensure that each market snapshot can be sequentially processed and transmitted.

In specific implementation, the message editing module may execute an editing processing operation according to the message processed by the message processing module, for example, a message header modification operation may be performed after the message processing module processes the message, where the message header modification operation includes adding a corresponding virtual switch name to a message header, performing tunnel encapsulation, and the like. In this manner, the transmission of the target market snapshot may be guided.

In specific implementation, the snapshot transmission module further comprises a message scheduling module and a message distribution module, wherein the message distribution module is used for being connected with an external network through an ethernet network so as to distribute the processed market broadcast message to the corresponding high-frequency transaction terminal. The message scheduling module mainly performs queue QoS (quality of service) processing, for example, the message scheduling module may set a priority for each market snapshot according to a preset rule, and perform traffic limitation according to the priority, thereby avoiding problems such as network congestion. The preset rule may be set according to a source of the target market snapshot, for example, referring to fig. 2 or fig. 3, a priority of the target market from the market cloud service host 1 is higher than that of the target market snapshot from the market cloud service host 2, and a priority of the target market snapshot from the market cloud service host 2 is higher than that of the target market snapshot from the market cloud service host 3.

As can be seen, in this example, by processing the target market snapshot by the snapshot transmission module and the message processing module, the problem that the interface broadband of the target market snapshot acquired by the second storage module from the first storage module is inconsistent with the ethernet interface broadband used for transmission can be solved. And whether the target market snapshot needs to be transmitted and processed in an accelerated manner or not can be judged in the process, so that the distribution speed of the market snapshot meeting the requirement is increased, and the user experience is improved. In this example, the snapshot transmission module and the message processing module process the target market snapshot to be transmitted, so that the transmission reliability can be improved.

In a possible example, before the target processing module of the processing chip obtains the target market snapshot after the transmission processing through the message processing module, and analyzes the target market snapshot after the transmission processing through the message processing module, and obtains the execution action information of the target market after the transmission processing, the method further includes: and the target processing module of the processing chip extracts the message header of the target market snapshot after transmission processing through the message cache module and sends the message header into the message processing module for processing.

The message header includes key information of the message of the target market snapshot, for example, information of an initial address, a target address, a source port, a destination port, and the like of the target market snapshot.

In specific implementation, the message caching module extracts a message header of the target market snapshot and sends the message header to the message processing module for processing, so that an editing action suitable for the target market snapshot is obtained. In the specific implementation, the message caching module sends the message header of the quotation snapshot to the message processing module for processing, caches the target quotation snapshot, and sends the target quotation snapshot to the message editing module after the message processing module completes the processing of the message header, so that the message editing module edits and processes the target quotation snapshot. The editing processing operation of the message editing module on the target market snapshot may be to modify a message header of the target market snapshot, for example, add a virtual switch name to the message header of the target market snapshot, perform tunnel encapsulation, and the like.

As can be seen, in this example, the message caching module extracts the message header of the target market snapshot after the transmission processing, and sends the message header to the message processing module for processing, so that the transmission efficiency of the message in the processing process can be improved while the transmission of the information is ensured.

In one possible example, referring to fig. 5, the message processing module includes a message parsing module, an access control module, a flow table matching module, and an execution action module; the target processing module of the processing chip obtains the target market snapshot after the transmission processing cached by the message caching module through the message processing module, and analyzes the target market snapshot after the transmission processing through the message processing module to obtain the execution action information of the target market after the transmission processing, and the method comprises the following steps: a target processing module of the processing chip receives the message header through the message analysis module and obtains a key field of the target market snapshot through analysis according to the type of the target market snapshot; a target processing module of the processing chip acquires the key field through the access control module and performs access control on the target market snapshot according to the key field by using a preset rule; the target processing module of the processing chip acquires the key field through the flow table matching module and matches a flow table entry corresponding to the key field; and the target processing module of the processing chip acquires the flow table entry obtained by matching through the action execution module and determines action execution information according to the flow table entry.

In specific implementation, the message analysis module extracts key fields of the target market quotation snapshot according to the type and the like of the target market quotation snapshot. The key fields of the target market snapshot comprise a starting address, a target address, a source port, a destination port, a transmission protocol and the like distributed by the target market snapshot. The type of the target market quotation snapshot is determined by the market quotation cloud service host which obtains the target market quotation snapshot, and the market quotation snapshot generated by each market quotation cloud service host can be distributed to the high-frequency transaction terminals which subscribe the market quotation cloud service host correspondingly. The distributed initial address is the address of the market server, the distributed destination address is the address of the high-frequency transaction terminal for receiving the target market snapshot, the source port is the port used by the market server for sending the target market snapshot, and the destination port is the port used by the target high-frequency transaction terminal for receiving the target market snapshot.

In specific implementation, the access control module may perform access control on the transmitted target market snapshot according to a predefined rule, where the predefined rule may be set according to a type of the target market snapshot, and may be specifically formulated according to a requirement, which is not limited herein. The operations of access control include, but are not limited to, performing operations of discarding, releasing, limiting bandwidth, accounting, etc. on the target market snapshot. Illustratively, the speed limit can be performed for the transmission of the target market snapshot from the market cloud service host 2.

In specific implementation, the flow table matching module may search in the flow table according to the key field of the target market snapshot extracted by the message parsing module, so as to match the processing flow table adapted to the target market snapshot. Each processing flow table comprises flow table entries generated by the control module corresponding to each situation cloud service host, and the flow table entries define processing rules of the processing chip for transmitting the target situation snapshot. And once the flow table matching module matches the processing flow table corresponding to the target market snapshot, the processing chip processes the received target market message according to the processing rule, so that the processed target market snapshot meets the distribution requirement.

Further, if the flow table matching module finds the flow table corresponding to the target market snapshot, the flow table matching module may notify the action execution module to obtain an action corresponding to the execution according to a field in the flow table corresponding to the action execution module, for example, the action executed by the action execution module includes: forwarding a destination port, determining an editing field of the target market snapshot, editing actions of the target market snapshot and the like, counting messages and the like. In specific implementation, the message editing module may further process the target market quotation snapshot according to the execution action information, such as the editing field of the target market quotation snapshot, the editing action of the target market quotation snapshot, and the like, determined by the execution action module. Illustratively, the execute action module may add a VxLAN outer tunnel encapsulation for the target market snapshot. For example, a VxLAN tunnel outer MAC and an outer IP may be added for the target market snapshot.

Therefore, in this example, different transmission processing operations can be performed on the target market snapshots from different market cloud service hosts, so that it can be ensured that the transmission of the different target market snapshots can meet the subscription requirements of different high-frequency transaction terminals.

In a possible example, the exchange integrated service system is further configured with a plurality of virtual switches, the virtual switches correspond to the market cloud service hosts one to one and are configured as market multicast groups one to one, and each market multicast group includes at least one high-frequency transaction terminal.

In a specific implementation, the exchange integrated service system may further include a switch device, and the plurality of virtual switches are disposed on the switch device. Still alternatively, multiple virtual switches may be deployed within the market server.

In this embodiment, a market conditions snapshot generated by a market conditions cloud service host is correspondingly deployed with a virtual switch, the virtual switch can be correspondingly deployed with a market conditions multicast group, and the high-frequency transaction terminal can join the corresponding market conditions multicast group according to a subscription condition. One market condition multicast group can be provided with a plurality of high-frequency transaction terminals, and one high-frequency transaction terminal can join a plurality of market condition multicast groups. Illustratively, referring to fig. 2, the high-frequency transaction terminal 200a is a device that joins a market conditions multicast group corresponding to the market conditions cloud service host 1 and a market conditions multicast group corresponding to the market conditions cloud service host 2. The device joining the market conditions multicast group corresponding to the market conditions cloud service host 2 includes a high frequency transaction terminal 200a and a high frequency transaction terminal 200b.

Therefore, in this embodiment, the data isolation in the sending process can be realized by sending the market snapshot of different products to the high-frequency transaction terminal in the market multicast group through different virtual switches, so as to ensure the accuracy of data transmission. The high-frequency transaction terminal can respectively join the market conditions multicast group of the virtual switch corresponding to each market condition cloud service host according to the subscription condition, so that market conditions snapshots of all subscribed target products are received, and user requirements are guaranteed.

Referring to fig. 6, fig. 6 is a schematic flow chart of a market snapshot distribution method applied to a high-frequency trading terminal according to an embodiment of the present application, where the method is applied to a target high-frequency trading terminal of a complex service system of a trading house, the complex service system of the trading house includes a market server and a plurality of high-frequency trading terminals, the target high-frequency trading terminal is any one of the plurality of high-frequency trading terminals, the target high-frequency trading terminal is a device joining a market multicast group of the market server, and the target high-frequency trading terminal includes a DPU and a host CPU. Illustratively, the method may be applied to any high frequency trading terminal in the exchange integrated services system 10 as shown in fig. 1 and 2.

As shown in fig. 6, the method for distributing the market snapshot includes:

and step S210, the DPU of the target high-frequency transaction terminal receives the market broadcast message from the DPU of the market server through the multicast tunnel of the market multicast group.

One market situation multicast group corresponds to a market situation snapshot of a target product generated by one market situation cloud service host. The quotation broadcast message is data including quotation information of a target product, which is obtained by a DPU of a quotation server after processing operations such as accelerated processing, transmission broadband limitation, encapsulation and the like are executed according to a quotation snapshot acquired from a CPU of a host.

In specific implementation, the high-frequency transaction terminal can apply for joining the market multicast group of the corresponding virtual switch according to the condition of subscribing the target product. For example, referring to fig. 2, the high-frequency transaction terminal 200a subscribes to a target product 1 and a target product 2, where the market cloud service host 1 may generate a market snapshot of the target product 1, and the market cloud service host 2 may generate a market snapshot of the target product 2, so that the high-frequency transaction terminal 200a may apply for joining a market multicast group of the LSW1 corresponding to the market cloud service host 1 and a market multicast group of the LSW2 corresponding to the market cloud service host 2.

Step S220, the DPU of the target high-frequency transaction terminal analyzes the market multicast message to obtain market information of the target product.

It can be understood that the DPU of the target high-frequency transaction terminal completes reception and analysis of the market multicast message, so that the processing pressure of the CPU of the target high-frequency transaction terminal can be reduced, and the working efficiency of the target high-frequency transaction terminal can be improved.

And step S230, the DPU of the target high-frequency transaction terminal sends the market information to a host CPU of the high-frequency transaction terminal.

In step S240, the DPU of the target high-frequency transaction terminal receives feedback information from the host CPU of the high-frequency transaction terminal.

And the feedback information is content information obtained by a host CPU of the high-frequency transaction terminal responding to the market information through a preset strategy service module. The strategy service module can provide transaction business functions such as buying or selling and the like for the user.

And step S250, the DPU of the target high-frequency transaction terminal sends the feedback information to the DPU of the market situation server through the multicast tunnel of the market situation multicast group.

In a specific implementation, the DPU of the target high-frequency transaction terminal may send the feedback information to the matching server, so that the matching server completes transaction matching, and then the matching server sends information such as matching results to the market server.

Therefore, in the embodiment of the application, the quotation broadcast message sent by the DPU of the quotation server can be received and analyzed by the DPU of the target high-frequency transaction terminal to obtain the quotation information of the target quotation snapshot, and then the quotation information is sent to the CPU of the target high-frequency transaction terminal by the DPU of the target high-frequency transaction terminal, so that a user can respond to the quotation information by a preset policy service module of a host CPU of the high-frequency transaction terminal to obtain feedback information, and the DPU of the target high-frequency transaction terminal can receive the feedback information and send the feedback information to the quotation server. Therefore, the work of receiving and analyzing the market broadcast message and the work of sending the feedback information corresponding to the market broadcast message by the target high-frequency transaction terminal are unloaded to the DPU for execution, so that the processing pressure of the CPU of the target high-frequency transaction terminal is favorably reduced, and the CPU of the target high-frequency transaction terminal can provide more calculation power to an application layer.
