In this embodiment, the method for reporting an extremely fast disk includes:

s1, obtaining a client entrusted data set, preprocessing the entrusted data set, and establishing an extremely rapid report data set.

In a preferred embodiment of the present invention, the user refers to an investor who is preparing or making an investment in securities, stocks or the like, for example, the user may be a white collar of a company, a business house or the like. In the preferred embodiment of the invention, the entrusted data of the user comprises entrusted transaction time, transaction direction, security codes, security quantity and the like, and the invention establishes an entrusted data set of the user according to the entrusted data of the user. The user entrusted data is generated by self-ordering of the user through an internet channel, a mobile phone app and other channels provided by a dealer.

The pre-processing operation is: and screening the entrusted data set of the user according to the urgency degree of entrusted transaction of the user submitting the entrusted data set to obtain a high-speed reporting data entrusted record set of a rush-stop board and a rush-stop board, and establishing the high-speed reporting data set according to the high-speed reporting data entrusted record set.

And S2, analyzing the elements in the speed quotation data set by a preset virtual transaction unit technology, and optimizing the elements in a pre-constructed speed quotation queue to obtain a target speed quotation data set.

Elements in the upfront dataset refer primarily to transactional elements, such as: security code, buying and selling direction, etc. The pre-constructed express reporting queue refers to a reporting path in a process of pushing a user's entrusting sheet to an exchange, and elements in the express reporting queue refer to elements of the reporting path in the process of pushing the user's entrusting sheet to the exchange. The pre-constructed speed quotation queue comprises: business department path, file path, etc., the elements in the rapid release queue include: the number of the business department path, the number of the file path, and the like. Preferably, the invention analyzes the elements in the extreme report data set and optimizes the elements in the report queue by a preset virtual transaction unit technology, thereby improving the transmission efficiency of report data. The virtual transaction unit technique of the preferred embodiment of the present invention includes a flow chart coordinate algorithm and a Branch Processing Unit (BPU). In a preferred embodiment of the present invention, the flowchart coordinate algorithm is used to analyze the elements in the rapid report dataset, and the specific operation steps of the analysis process are as follows: acquiring serial-parallel information of data in a polar speed report data set of a user, such as A & & < B | C & & D > & & E; configuring DSL language for the serial-parallel information and converting the DSL language into a directed acyclic graph; presetting a certain flow direction to carry out topological sequencing on the directed acyclic graph; and presetting certain virtual nodes according to the topological sorting, realizing the dotted line intersection of the flow chart, and finishing the element analysis in the extreme speed report data set. Preferably, the preset flow direction of the present invention is from top to bottom and from left to right, and the topological sorting is used for placing the nodes of the information on different levels.

Furthermore, the invention realizes the optimization processing of the elements in the extreme speed report queue through the BPU. The BPU refers to an area used by the CPU for branch processing. In detail, the optimization process is as follows: the IPC shared memory area is established through a Linux shared memory and used for placing data to be shared among all processes in the shared memory, and the data access is carried out by mapping the IPC shared memory area to the address space of the processes. The process is an element for performing optimization processing in the report queue in the invention. Preferably, the Linux shared memory adopted by the invention is a System V shared memory. In detail, the API interfaces mainly supported by the System V shared memory are as follows:

a.int shmget(key_t key,size_t,size,int flag)

through the shmget () function, a process can obtain or create an IPC shared memory region and return the corresponding identifier when successful. The identifier returned is a unique identifier when the shared memory of the block is used, wherein the identifier can also be obtained by inquiring through ipcs-m executed in a command line. The parameter (key) in the function is a parameter for controlling the shared reference identifier when proposing the shared memory, and different processes need to provide the same value at the position of the parameter in order to obtain the identifier of the same shared memory. The value of the key is required to be agreed by all parties, a file is created in the position agreed by all parties in the file system, and the file index node number of the file is calculated by using a ftok () function and is used as the key value.

b.void*shmat(int shmid,const void*addr,int flag)

By using the shmat () function, the process can map (attach) the created shared memory region into the address space of the calling process, and the process can directly access the shared region by returning a value, that is, an address pointer in the address of the process after the memory block is mapped. Where the shmid parameter, i.e., the shared memory identifier returned by the shmat () function, usually a parameter other than shmid, does not need to be specified, the shared memory identifier representing the relative position in program address space selected by the kernel.

c.int shmdt(void*addr)

After the shmdt () function is called, the mapping of the shared memory domain by the process can be released, and addr is a mapping address returned when shmdt is called.

d.int shmctl(int shmid,int cmd,struct shmid_ds*buf)

And when the shared memory is determined not to be used any more, actively calling the shmctl () function to delete the created shared memory area, and executing the command through the ipcrm command line to delete a shared memory. In addition, the shmctl may be used to implement control operations such as modifying a state of the shared memory domain.

Preferably, the host network card adopts a Gigabit (GB) high-bandwidth optical network card, and is matched with a full-function Gigabit (GB) Ethernet switch for use. The shorter the distance between the appropriate host and the network cable or optical fiber connecting cable of the Ethernet switch, the smaller the system delay. Furthermore, the Ethernet two-layer switch independent of each subsystem of the system transmits the data of all the subsystems on the independent Ethernet two-layer switch, avoids the interference among different data, achieves point-to-point direct forwarding without a routing function, and effectively reduces the time delay of a network card communication link.

The optimized network architecture adopts a two-layer network architecture (dual-redundancy network architecture) to optimize the network architecture. In detail, the dual-redundancy network architecture adopts a full-redundancy network architecture, wherein a process component of the network architecture adopts two-way multi-active-standby, and a queuing arbitration mechanism is introduced to ensure the high efficiency and stability of emergency switching. Further, the dual redundant network architecture mainly comprises: each system component realizes double active hot standby, the exchanger realizes double hot standby, each subsystem host network card adopts the binding technology of double network cards to connect two double hot standby exchangers, so that the normal operation of the system can not be influenced by the single fault of any system component and network exchanger, and the requirements of high efficiency, stability and strong risk resistance of quick transaction are met.

The bypass rapid report component is used for expanding the rapid report system, forms various service rules according to abstraction of services, analyzes the service rules, minimizes the influence of the service rules, minimizes the influence when a new rule is added or the original rule is adjusted, adopts an independent report transaction channel, and distinguishes the report transaction channel of the bypass report component from the report channel of the rapid report system, thereby ensuring that the operation of the rapid report system is not influenced when the report is subjected to order taking.

The configuration gateway uses a step protocol and a step interface by setting the gateway. The step protocol is a Chinese financial industry data communication standard JR/T0022-2004, is adopted by Shenzhen exchange at present, and is used as a standard protocol of data distributed to an information service provider by Leve I data.

Further, in the preferred embodiment of the present invention, a one-to-one correspondence relationship is established between the reporting gateway of the original computer room and the very fast reporting gateway, including the same transaction units and the one-to-one correspondence of the number of transaction units, so as to ensure that the transaction data is the same during the transaction and the rotation. Furthermore, the rapid quotation system is deployed in the Shenzhen stock exchange machine room, on one hand, the server can be directly connected with the related exchange system of the Shenzhen stock exchange, and a client can more conveniently operate a host of the client through remote control for maintenance and application; on the other hand, the system can directly jump to a deep-transit station machine room through a special line on the router for reporting, thereby reducing the reporting distance and reducing the transmission time loss. Preferably, the software and hardware equipment in the rapid quotation system are deployed to a rental machine room of the deep-licensed exchange, and the rapid quotation system and a host of the deep-licensed exchange are established under the same local area network, so that the timeliness of transaction data in the transmission process is ensured.

The TGW is a trading gateway and is an access point provided by a Shenzhen stock exchange trading system for market participants, wherein the TGW supports access to the Shenzhen stock exchange trading system through a STEP protocol and a Binary protocol, submits orders and acquires execution reports. The bidding rules match the deals according to rules of price priority and time priority. The rules of price priority are as follows: higher price buy declarations are preferred over lower price buy declarations, lower price sell declarations are preferred over higher price sell declarations. The time-first rule is as follows: the business direction and the price are the same, and the first declarator takes precedence over the later declarator.
