Detailed Description
In the prior art, market data is transmitted to a driver through a pcie channel, the driver copies an internal memory after receiving the market data, and then distributes the market data to corresponding software receiving processes according to market categories. Because the driver needs memory copy to send the quotation data to the software process after receiving the quotation data, the memory copy action brings great transmission delay, and the drive distribution of the quotation data is a serial processing process, thereby increasing the transmission delay of the quotation data and reducing the stability of the quotation data processing system. In order to overcome the technical problems, the application provides a market data transmission method based on a pcie multichannel, which can reduce data transmission time delay and improve the data processing capacity and stability of a system.
The embodiment of the application discloses a market data transmission method, which is shown in fig. 1 and can comprise the following steps:
step S11: acquiring market data through a board card, and classifying the market data to obtain target type market data.
In this embodiment, market data is first obtained through the board card, and the market data is classified to obtain target type market data. The method comprises the steps that market data sent by a trading exchange are obtained through a hardware board card, and the market data are classified through an internal market processing module according to user requirements to obtain one or more types of target type market data; the original market data packet is obtained, and irrelevant market data are filtered according to the market types to obtain target type market data. The classification criteria of the market data may include, but are not limited to, consignment by consignment, deal by deal, market snapshot, and index snapshot.
Step S12: and allocating a separate pcie channel for each target type market data, and transmitting the target type market data to a host through the pcie channel.
In this embodiment, after the target type market data is obtained, a separate pci channel is allocated to each target type market data, and then the target type market data is transmitted from the board card to the host through the pci channel. According to the types of the market data, different types of market data enter different pcie channels, and the different pcie channels transmit a plurality of types of target type market data in parallel. Specifically, the obtained target market data can be put on different pcie channels in a unified calculation mode, so that the market data received by the application layer does not need to be filtered, and the market data of the channels can use the same magnification factor so as to be convenient to calculate; and for the market data which does not need to be concerned, the information receiving processing of other channels can be directly discarded and not interfered. Meanwhile, different types of quotations walk through different hardware pcie channels in a hardware pcie multi-channel parallel transmission mode, the quotations of different types can be processed in parallel, parallel data processing in hardware can be compatible, and data processing capacity is improved.
Step S13: and receiving the target type market data through a target process corresponding to the pcie channel in the host.
In this embodiment, after the target type market data is transmitted to the host through the pcie channel, the target type market data is received and processed by using a target process corresponding to the pcie channel in the host. It can be understood that a software receiving process is started for each pci channel at the terminal, and each pci channel directly performs data interaction with a target process, that is, target type market data of one pci channel is processed by one process. For example, as shown in fig. 2, the original market data may be transmitted to the hardware parsing module in an optical splitting manner, that is, all market contents from the network are received through a network access, after the hardware parsing module of the board receives the original market data, the original market data are classified according to different market types, four types of target market data, namely, order, bargain, snapshot and index, are obtained through market classification, and then a pci channel is allocated to each type of market data and handed over to different threads for processing; the four market conditions types are put into different channels to be uploaded by utilizing a pcie multichannel parallel scheme, and the application layer receives market condition data of each channel in a multithreading mode. Each target type market data in the host can be received and processed by one or more threads, or can be received and processed by a single process.
Therefore, different types of target type market data are obtained by classifying the market data, then an independent pcie channel is distributed for each type of target type market data, and multi-channel target type market data are transmitted on a hardware pcie layer. Moreover, the software process directly communicates with the Pdie channel, so that memory copy and data distribution of the driver are avoided, each Pdie channel directly performs data interaction with the corresponding target process, and channel switching and data copy between the driver and each process can be omitted; the software layer uses a multi-channel parallel mode, can process various quotations in parallel, improves the system quotation processing capacity, and the data receiving and processing of other software processes can not be influenced due to the low processing speed of one software process.
The embodiment of the application discloses a specific market data transmission method, which is shown in fig. 3 and can include the following steps:
step S21: acquiring market data through a board card, and classifying the market data to obtain target type market data.
Step S22: and distributing an independent pcie channel for each target type market data, and packaging the target type market data to obtain a corresponding market data packet.
In this embodiment, after obtaining the target type market data, package the target type market data to obtain a corresponding market data packet; specifically, the packaging process may include, but is not limited to, adding header information.
Step S23: and transmitting the market data packet to the host through the pcie channel.
In this embodiment, after the quotation data packet is obtained, the quotation data packet is transmitted to the host through the pcie channel, and a corresponding software process is notified to read data; specifically, the market data packet may be transmitted to the host through a pcie ip core of the board card and a pcie ip core of the host. For example, as shown in fig. 4, after receiving a market data packet transmitted by a hardware pci channel, a pci ip core of a hardware board sends the market data packet to a pci ip core of a computer motherboard.
Step S24: writing the quotation data packet into a corresponding independent storage area in the host according to a preset storage relation; and the preset storage relationship is the corresponding relationship between the pcie channel and the independent storage area.
In this embodiment, after receiving the market data packet, the host writes the market data packet into a corresponding independent storage area in the host according to a preset storage relationship; wherein, the preset storage relationship is the corresponding relationship between the pcie channel and the independent storage area; it can be understood that the driver applies one or more independent storage areas for each pcie channel in the memory, and stores the market data packet passing through the pcie channel to the corresponding storage area. For example, as shown in fig. 4, after the pcie ip core of the motherboard receives the market data packet, the market data packet is stored in the storage space corresponding to the pcie channel by using the software layer pcie channel according to the header information of the data packet.
Step S25: reading the market data packet in the corresponding independent storage area by using a target process in the host according to a preset reading relation; and the preset reading relation is the corresponding relation between the target process and the independent storage area.
In the embodiment, the market data packet in the corresponding independent storage area is read by using the target process in the host according to the preset reading relation; the preset reading relation is the corresponding relation between the target process and the independent storage area. It can be understood that a target process reads an independent storage area corresponding to a pci channel.
Step S26: releasing the independent storage area; and sending corresponding storage area release information to the board card through the pcie channel.
In this embodiment, for example, as shown in fig. 4, after the target process reads the target market data packet in the independent storage area, the corresponding independent storage area is released, and the hardware board is notified through the pcie channel, and the independent storage area is released and can be used continuously.
In this embodiment, the market data transmission method may further include: receiving order data sent by a counter through a network port of the board card, and determining a seat corresponding to the order data according to a target field in the order data; and sending the order data to an application program through a pcie channel corresponding to the seat, and forwarding the order data to a trading exchange through an API (application programming interface) by the application program. It can be understood that, for example, as shown in fig. 5, in the counter trading system, a user places an order and sends and receives an order response through a seat, in this embodiment, each seat corresponds to a pcie channel, and after receiving order data sent by the counter, the board card determines the seat corresponding to the order data by looking up a seat field in the order data. And then the order data is sent to an application program through the pcie corresponding to the seat, and the application program forwards the order data to the exchange through an API example interface of the exchange.
Compared with the prior art, a single pcie channel transmission mode is generally used before a hardware counter system, all seats share one pcie channel, a driver copies and forwards data after receiving a market situation, the single performance of each seat is influenced by the driving performance, and multi-seat queuing processing is needed for issued order response data. In the embodiment, each seat occupies one channel in a pcie multichannel parallel mode, the seats are directly independent and do not influence each other, and each seat only needs to process data of the corresponding channel, so that the ordering performance of the system can be improved.
For the specific process of the step S21, reference may be made to the corresponding contents disclosed in the foregoing embodiments, and details are not repeated here.
As can be seen from the above, the market data packet is written into the corresponding independent storage area in the host according to the preset storage relationship, wherein the preset storage relationship is the corresponding relationship between the pci channel and the independent storage area; and reading the market data packet in the corresponding independent storage area by using the target process in the host according to a preset reading relation, wherein the preset reading relation is the corresponding relation between the target process and the independent storage area. Therefore, the rapid transmission of market data is realized by utilizing the corresponding relation between the pcie channel and the independent storage area and the corresponding relation between the independent storage area and the target process, the time delay of data transmission is reduced, each pcie channel directly carries out data interaction with the corresponding target process, and channel switching and data copying between a driver and each process can be omitted; meanwhile, the software layer adopts a multi-channel parallel mode to process various quotations in parallel, and the quotation processing capacity of the system is improved.
