The invention discloses an extremely-low-delay reliable communication system and method for a financial transaction system. The system comprises a low-delay switch, a low-delay network card, an FPGA and a server. The low-delay switch is used for forwarding a transaction data packet, and the delay is hundreds of ns; the low-delay network card is used for data encapsulation and de-encapsulation, link management, coding and decoding; the FPGA is used for carrying out hardware acceleration processing on a reliable communication message protocol; the server runs a high-performance communication component, is used for reliable communication protocol software processing, and can perform one-to-many or many-to-many scene publishing and subscribing. The invention relates to the technical field of financial transactions, and is applied to exchange system market release, a transaction center market transaction gateway and a transaction counter. According to the technology and the method, the large-scale programmable FPGA and software and hardware are adopted for collaborative acceleration, flexible customization can be achieved according to service characteristics, and the method has the advantages of being large in capacity and high in processing speed; the method can effectively cope with a high-concurrency scene, and is short in system response time.
Description
technical field [0001] The invention relates to the technical field of financial transactions, in particular to an extremely low-latency reliable communication system and method for financial transaction systems. Background technique [0002] Transaction processing performance is an important indicator that reflects the core competitiveness of electronic trading platforms, and communication delay is one of the core factors that affect the overall transaction performance. At present, the world's leading electronic trading platform has reduced communication delay to less than 50 microseconds. Compared with the domestic trading center trading system, there is obviously still a lot of room for improvement in indicators such as processing performance. [0003] The traditional trading platform consists of a market system and a market gateway, and the communication components are used for communication and data transmission components of the central information system, such as fig...
