Protocol processing system and method for realizing TCP quick report of security counter

Abstract

The invention provides a protocol processing system for realizing TCP quick report of a security counter, which comprises an optical module of a client and an optical module of a transaction end, oneend of the optical module of the client is connected with the client, the other end of the optical module of the client is connected with an FPGA, one end of the optical module of the transaction endis connected with the FPGA, the other end is connected with an exchange, and the FPGA is connected with the CPU. The invention also provides a processing method of the protocol processing system for realizing TCP quick report of the security counter. Compared with an existing TCP / IP protocol stack based on a software architecture or pure hardware, the method provided by the invention reserves partof functions of process management of the software protocol stack, is used for processing services with low delay requirements, can ensure the stability of the whole system, and improves the reliability of the system. In addition, the report service with higher penetration delay requirement and larger data volume is directly transmitted through the FPGA, so that the low penetration delay requirement of the system is improved, and the CPU software processing overhead is greatly reduced.

Description

technical field [0001] The invention belongs to the field of quick orders for financial transaction systems such as securities and stocks, and relates to a protocol processing system and method for realizing TCP quick orders for securities counters. Background technique [0002] With the development of globalization in the financial field, higher and higher requirements are put forward for the low latency of various trading systems. In order to reduce the latency as much as possible, the business processed by the original software is continuously sinked to the hardware for acceleration. Not only that, the entire financial transaction system also pursues full-path low-latency penetration. With the development of network technology, more and more communication technologies are also applied to the financial field. For example, in order to reduce the burden on the host CPU, especially System overheads such as data copying, protocol processing, and interrupt processing, and TCP / I...

[0002] With the development of globalization in the financial field, higher and higher requirements are put forward for the low latency of various trading systems. In order to reduce the latency as much as possible, the business processed by the original software is continuously sinked to the hardware for acceleration. Not only that, the entire financial transaction system also pursues full-path low-latency penetration. With the development of network technology, more and more communication technologies are also applied to the financial field. For example, in order to reduce the burden on the host CPU, especially System overhead such as data copying, protocol processing, and interrupt processing, etc., TCP / IP protocol stack processing puts a heavier burden on the CPU, and connection maintenance, sending and receiving management, and error management are all processed by the software protocol stack, which also results in a relatively long processing delay
