The existing wind control scheme is to select a wind control module of a high-performance trading desk to realize wind control inspection, and for a counter trading cluster, each trading desk is provided with the wind control module to independently complete the wind control inspection, namely, the distributed wind control scheme.
There are problems:
1. along with the increasing of wind index checking items, the complexity of index operation and judgment is increased continuously. The time delay of the transaction counter processing is affected more and more, and the wind control algorithm and the index cannot be dynamically loaded and take effect in real time.
2. Distributed wind control calculation needs independent decoding and caching of market data, transaction success return data, transaction return data and configured wind control index strategies, repeatedly occupies counter resources, wastes calculation CPUs and is low in reliability.
3. Distributed sub-control calculation cannot realize the load balancing function of the trading desk cluster, and the sub-control calculation occupies more resources when some trading desk entrusts more orders. And the counter with light load can not bear wind control calculation and can not be effectively utilized.
4. Distributed sub-control cannot perform centralized index calculation, namely index calculation is performed on all the entrustment bill subsets together, and data hashing cannot be updated in a centralized mode at each trading counter.
5. The distributed sub-control log system is recorded in each transaction counter, all the wind control, entrustment and transaction information can be left in the log system, and the log system needs to be combined to facilitate the retrospective wind control, and due to time synchronization difference, the work load of log combination processing is large.

The remaining three processes are data interfaces and processing, and the main backup operation is required in consideration of the high reliability requirement of the system. And once the management process finds the abnormality, the main/standby switching takeover is carried out.
In the embodiment of the present invention, the distributed data cache specifically includes:
1. configuring data cache CfgCache
The method is generated by a centralized wind control management process TacControl, and is generated by reading a configuration xml file when starting. And query and modification can be carried out through an offline configuration tool shell, and the data is submitted and then synchronized to the configuration data cache in real time. The real-time effect of the wind control parameters can be achieved.

3. TrustCache for entrusted return data cache
And the entrustment return response message pushed by the exchange is analyzed and decoded and then stored in the data cache for the entrustment abnormal wind control process to use.
4. Transcache for transaction return data caching
And the transaction service process TradeFwd generates and analyzes the transaction return response message pushed by the exchange, and the transaction return response message is decoded and stored in the data cache for the entrusting abnormal wind control process.
5. Log memory database LogCache
The method is used by a running log process Logger, and in order to accelerate log storage, improve the throughput of a log system and ensure high availability of log records, the method of recording by using a memory database mode is considered, and log files are written into periodically or after a recording threshold value is reached for persistence. The log records may be compressed with consideration to save disk space.

The standby service is also connected with the market information pushing gateway and can generate real-time market information one by one.
In the embodiment of the invention, high availability is realized through the main-standby mode, and a connection synchronization method based on TCP without interruption is designed so as to meet the requirement of high reliability of financial transactions. The master-slave relationship is shown in FIG. 6
The main server and the external system normally communicate through TCP, TCP connection following is established on the standby server, the standby server can receive all main messages in a monitoring mode, and the TCP connection of the standby server follows messages and a protocol state machine by modifying a tacdock user state TCP protocol stack, but the TCP messages and control messages are not sent, and the network card FPGA only receives and does not send the messages.
Whether a fault occurs is judged between the main and standby devices through heartbeat detection. And when the standby server finds that the heartbeat data of the main server does not arrive for three continuous seconds, the standby server judges that the main server sends a fault, executes a main/standby switching instruction and promotes the standby server to be the main server. Once the main/standby switching instruction occurs, the standby server actively sends a gratuitous ARP message to update the relationship between the MAC address and the IP address of the port of the switch. Meanwhile, the main FPGA needs to cut off the message transmission of the server. The tacdock protocol stack on the standby server takes over the work and enters the service state from the following state. The standby server can receive messages of all exchanges in a hot backup mode, and data synchronization is not performed between the main server and the standby server. And synchronously inquiring data of the increment time period from the exchange for data consistency after switching. When the main and standby switches, the exchange and the counter system are not needed to be modified and matched, no perception or little perception is realized, and the fault recovery speed is high.
And those not described in detail in this specification are well within the skill of those in the art.
