As shown in fig. 1, the system architecture 100 may include terminals 101, 102, a layer of switches 103, and a server 104.
The terminals 101 and 102 may be communicatively connected to the one-layer switch 103, so that the terminals 101 and 102 transmit data to the one-layer switch 103, or the terminals 101 and 102 obtain data from the one-layer switch 103. As an example, the terminals 101, 102 may establish a communication connection with the layer switch 103 through an optical fiber. Fiber optic connections may also be used between the switches 103 and the servers 104, so that data (e.g., transaction instructions) may be transmitted between the switches 103 and the servers 104.

However, only one of the two or more data forwarding interfaces is used for forwarding data to the server. The data forwarding interface for forwarding the data to the server side can be a fixed one of two or more data forwarding interfaces; or one of the two or more data forwarding interfaces may be selected according to a certain rule. In other words, at a particular time, the layer one switch 103 has one and only one data forwarding interface for forwarding data to the server. But the number of data forwarding interfaces that it has on its physical structure may not be limited to one.
The server 104 may be used to provide various services. For example, the server 104 may be configured to exchange the released market data, and/or perform corresponding operations according to the received operation instructions, for example, perform a buy operation or a sell operation according to the transaction instructions sent by the user through the terminal.
The server may be hardware or software. When the server is hardware, it may be implemented as a distributed server cluster formed by multiple servers, or may be implemented as a single server. When the server is software, it may be implemented as multiple pieces of software or software modules (e.g., software or software modules used to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
It should be further noted that the data transmission method of the layer one switch provided by the embodiments of the present disclosure may be performed by the layer one switch or other electronic devices. Accordingly, the various parts (e.g., various units, sub-units, modules, sub-modules) included in the data transmission apparatus of the first-layer switch may be all provided in the first-layer switch or other electronic device.
It should be understood that the number of terminals in fig. 1 is merely illustrative. There may be any number of terminals, as desired for implementation.
Fig. 2 shows a flow 200 of a data transmission method of a layer switch according to an embodiment of the present disclosure. The method is applied to a layer switch with a data forwarding interface for forwarding data to a server, the layer switch with the data forwarding interface for forwarding data to the server is in communication connection with at least two terminals, and the data transmission method of the layer switch comprises the following steps:
In this embodiment, an execution main body of the data transmission method of the first-tier switch (e.g., the first-tier switch shown in fig. 1) may receive, from at least two terminals, at least two operation instructions respectively sent by the at least two terminals in a wired connection manner or a wireless connection manner.
It should be noted that the above-mentioned layer switch may have two or more data forwarding interfaces. However, only one of the two or more data forwarding interfaces is used for forwarding data to the server. The data forwarding interface for forwarding the data to the server side can be a fixed one of two or more data forwarding interfaces; or one of the two or more data forwarding interfaces may be selected according to a certain rule. In other words, at a particular time, the layer one switch 103 has one and only one data forwarding interface for forwarding data to the server. But the number of data forwarding interfaces that it has on its physical structure may not be limited to one.
The operation instructions may be used to instruct various operations to be performed. As an example, the operation instructions may include, but are not limited to: buy orders, sell orders, etc.
In this embodiment, the execution body may sequence the at least two instructions received in step 201 to obtain an operation instruction sequence.
Here, the execution body may sort the at least two operation instructions in various ways, and use the sorted result as an operation instruction sequence.
As an example, the execution body may randomly sort the at least two operation instructions, or sort the operation instructions according to a predetermined sorting rule.
In some optional implementations of this embodiment, the first layer of switch includes a Field Programmable Gate Array (FPGA) chip. On this basis, the executing body may execute the step 202 as follows:
and sequencing the at least two operation instructions through the field programmable gate array chip to obtain an operation instruction sequence.
The FPGA belongs to a semi-custom circuit in an application-specific integrated circuit, is a programmable logic array, and can effectively solve the problem of less gate circuits of the original device. The basic structure of the FPGA comprises a programmable input/output unit, a configurable logic block, a digital clock management module, an embedded block RAM (Random Access Memory), a wiring resource, an embedded special hard core and a bottom layer embedded functional unit. The FPGA has the characteristics of abundant wiring resources, high repeatable programming and integration level and low investment, and is widely applied to the field of digital circuit design. The Design process of the FPGA comprises algorithm Design, code simulation, Design and trigger debugging, an algorithm framework is established by a designer and actual requirements, a Design scheme is established by using EDA (electronic Design Automation) and the like, the Design scheme is ensured to meet actual requirements through code simulation, board-level debugging is finally carried out, related files are downloaded to an FPGA chip by using a configuration circuit, and the actual operation effect is verified.
It can be understood that, in the above optional implementation manner, the operation instructions can be sequenced through the FPGA chip, so that the phenomenon of signal collision occurring when a plurality of terminals forward data to the server through one data forwarding interface of one layer of switch can be reduced or even avoided by using the FPGA chip.
In some optional implementations of this embodiment, the executing main body may execute the step 202 in the following manner:
and sequencing the at least two operation instructions based on the sequencing information of each of the at least two terminals. The sequencing information represents the sequence of sequencing the historical operation instructions sent by the terminal.
In some application scenarios in the foregoing optional implementation manner, the sorting information includes a sorting weight, and the larger the sorting weight is, the more front the arrangement order is represented. On this basis, the execution body may sort the at least two operation commands based on the sorting information of each of the at least two terminals in the following manner:
first, for the ranking weight of each of the at least two terminals, if the ranking weight of the terminal is greater than or equal to the preset weight, the ranking weight of the terminal may be decreased (for example, the updated ranking weight of the terminal is obtained by subtracting a preset first value from the ranking weight of the terminal); if the ranking weight of the terminal is less than the preset weight, the ranking weight of the terminal may be increased, for example, the updated ranking weight of the terminal is obtained by subtracting a preset second value from the ranking weight of the terminal), so as to obtain the updated ranking weight of the terminal.
And then, sorting the at least two operation instructions based on the updated sorting weight of each of the at least two terminals.
As an example, the execution body may sort the at least two operation instructions in an order from a larger ranking weight to a smaller ranking weight of each terminal.
It can be understood that, in the above alternative implementation manner, the updated sorting weight may be obtained by decreasing the larger sorting weight and increasing the smaller sorting weight, and the operation instructions are sorted based on the updated sorting weight. Thus, the arrangement sequence of the operation instructions transmitted by each terminal can be more balanced. For example, if the sequence of the operation commands sent by a terminal last time is earlier, the sequence of the operation commands sent by the terminal this time may be later.
Here, the larger the ranking weight is, the later the ranking order is. On this basis, the execution body may sort the at least two operation commands based on the sorting information of each of the at least two terminals in the following manner:
first, for the ranking weight of each of the at least two terminals, if the ranking weight of the terminal is greater than or equal to the preset weight, the ranking weight of the terminal may be decreased (for example, the updated ranking weight of the terminal is obtained by subtracting a preset first value from the ranking weight of the terminal); if the ranking weight of the terminal is less than the preset weight, the ranking weight of the terminal may be increased, for example, the updated ranking weight of the terminal is obtained by subtracting a preset second value from the ranking weight of the terminal), so as to obtain the updated ranking weight of the terminal.
And then, sorting the at least two operation instructions based on the updated sorting weight of each of the at least two terminals. As an example, the execution body may sort the at least two operation instructions in an order from a smaller order to a larger order of the updated sorting weight of each terminal.
Optionally, the execution main body may further calculate a mean value of the ranking weights of the operation instructions sent by each terminal in the history, to obtain a mean value corresponding to the terminal, so as to rank the operation instructions sent by each terminal according to a descending order or a descending order of the mean value corresponding to each terminal.
It can be understood that, in the above alternative implementation manner, the order of the operation instructions sent by each terminal this time may be determined based on the order of the sorting performed by the historical operation instructions sent by each terminal, so that the order of the operation instructions sent by each terminal is more balanced, and the occurrence of data skew is reduced to a certain extent.
And step 203, sending each operation instruction in the operation instruction sequence to a server end in communication connection with the layer of switch through the data forwarding interface according to the sequence indicated by the operation instruction sequence.
In this embodiment, the execution main body may send each operation instruction in the operation instruction sequence to a server communicatively connected to the first-tier switch through the data forwarding interface in an order indicated by the operation instruction sequence.
In some optional implementations of this embodiment, the executing main body may execute step 203 in the following manner:
and integrating the operation instructions in the operation instruction sequence into a group of data according to the sequence indicated by the operation instruction sequence, and sending the group of data to a server end in communication connection with the first-layer switch through the data forwarding interface.
It can be understood that, in the above alternative implementation manner, the plurality of operation instructions may be integrated into one set of data according to the sequence indicated by the operation instruction sequence, so that one set of data including the plurality of operation instructions is sent to the server through one sending operation, thereby reducing the number of communications with the server.
In some optional implementations of this embodiment, the executing main body may also execute step 203 in the following manner:
and sequentially sending each operation instruction in the operation instruction sequence to a server end in communication connection with the layer of switch through the data forwarding interface according to the sequence indicated by the operation instruction sequence.
It can be understood that, in the above alternative implementation manner, after a plurality of operation instructions are sequenced, the operation instructions are sequentially sent to the server one by one according to the sequence indicated by the operation instruction sequence, so that by sending each operation instruction in sequence, a phenomenon of signal collision occurring when a plurality of terminals forward data to the server through one data forwarding interface of one layer of switch is reduced or even avoided.
In some optional implementation manners of this embodiment, in the case of receiving the data sent by the server, the execution main body may further send the data sent by the server to at least one of the at least two terminals.
It can be understood that, in the above alternative implementation manner, the first layer switch may receive the data sent by the server without special processing such as sorting, so that bidirectional transmission of the data may be implemented on the same physical connection. However, from the network layer, the terminal sends data to the first layer of switch, the first layer of switch forwards the data to the server, the server sends the data to the first layer of switch, and the first layer of switch forwards the data to the terminal, which belong to two different network connections.
In some optional implementations of this embodiment, the data forwarding interface is configured to connect to an optical fiber.
It can be understood that, in the above alternative implementation manner, the service end can receive and forward the operation instructions sent by the at least two terminals without conflict only by using one optical fiber, so that the hardware cost of the service end (for example, a service end deployed in a trading exchange) is reduced.
In some optional implementations of this embodiment, the first layer switch has at least two data input interfaces, and each of the at least two data input interfaces is communicatively connected to each of the at least two terminals.
It can be understood that, in the above optional implementation manner, the transaction instruction sent by each terminal may be transmitted to the inside of the switch through different data input interfaces, so that a phenomenon of signal collision occurring when a plurality of terminals forward data to the service end through one data forwarding interface of one layer of switch is reduced or even avoided.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the data transmission method of the layer one switch according to the present embodiment. In the application scenario of fig. 3, the switch 310 of the first layer has one and only one data forwarding interface 311 for forwarding data to the server, and the switch 310 of the first layer is communicatively connected to at least two terminals. In fig. 3, after the first-layer switch 310 receives the two operation instructions 301 and 302 respectively sent by the at least two terminals, the first-layer switch 310 sequences the operation instructions 301 and 302 to obtain an operation instruction sequence 303. Subsequently, the first-tier switch 310 transmits each operation command in the operation command sequence 303 to a server communicatively connected to the first-tier switch through the data forwarding interface 311 in the order indicated by the operation command sequence. As shown in fig. 3, the first-tier switch 310 transmits each operation instruction in the operation instruction sequence 303 to the server 320 communicatively connected to the first-tier switch 310 through the data forwarding interface 311 in the order of the operation instructions 301 and 302.
In the method provided by the foregoing embodiment of the present disclosure, a first-tier switch has only one data forwarding interface for forwarding data to a server, and the first-tier switch is in communication connection with at least two terminals, and can receive at least two operation instructions respectively sent by the at least two terminals, then sequence the at least two operation instructions to obtain an operation instruction sequence, and finally send each operation instruction in the operation instruction sequence to the server in communication connection with the first-tier switch through the data forwarding interface according to the sequence indicated by the operation instruction sequence. Therefore, after the operation instructions are sequenced, the operation instructions are forwarded to the server side through one data forwarding interface of one layer of switch according to the sequence, and the phenomenon of signal collision in the process that a plurality of terminals forward data to the server side through one data forwarding interface of one layer of switch is reduced or even avoided. In addition, the method provided in the foregoing embodiment limits the application scenario to the first-tier switch, which can reduce the delay compared to a scheme using a second-tier switch and a third-tier switch, and limits the application scenario to one data forwarding interface, which can reduce the cost compared to using two or more data forwarding interfaces, for example, in a scenario where the service end provides a transaction, the problem that the price of the place of the transaction is high can be solved to some extent. Therefore, under the scene that the server side is provided by the exchange, the embodiment can realize a one-to-many communication mode between the exchange and the terminal, save some seat resources and greatly reduce the time delay.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method of data transmission for a layer switch is shown. The process 400 of the data transmission method of the layer switch includes the following steps:

And step 403, sending each operation instruction in the operation instruction sequence to a server end in communication connection with the layer of switches through the data forwarding interface according to the sequence indicated by the operation instruction sequence.
In this embodiment, step 403 is substantially the same as step 203 in the corresponding embodiment of fig. 2, and is not described herein again.
It should be noted that, besides the above-mentioned contents, the embodiment of the present disclosure may also include the same or similar features and effects as the embodiment corresponding to fig. 2, and no further description is provided herein.

Referring to fig. 5, fig. 5 is a schematic diagram of an interaction process of a data transmission system of a layer switch according to an embodiment of the present disclosure.
The data transmission system of the first-layer switch comprises at least two terminals, a first-layer switch with a data forwarding interface for forwarding data to a server, and a server, wherein each of the at least two terminals is in communication connection with the first-layer switch, and the server is in communication connection with the first-layer switch, wherein: the above-mentioned one-layer switch is configured to: in response to the fact that the first-layer switch receives at least two operation instructions sent by the at least two terminals, sequencing the at least two operation instructions to obtain an operation instruction sequence; and sending each operation instruction in the operation instruction sequence to the server end sequentially through the data forwarding interface according to the sequence indicated by the operation instruction sequence.
In fig. 5, in steps 501 and 502, two terminals respectively transmit operation instructions 1 and 2 to a layer switch.

And step 504 and step 505, the first-layer switch sequentially sends the operation instruction 1 and the operation instruction 2 to the server.
It should be noted that, in addition to the above-mentioned contents, the steps executed by the terminal, the first-layer switch, and the server in the data transmission system of the first-layer switch may be implemented in the manner described with reference to fig. 2 to 4, that is, the data transmission system of the first-layer switch may include the same or corresponding technical features and produce the same or corresponding technical effects as those described in the data transmission method of the first-layer switch, and will not be described herein again.
