Abstract

The invention discloses a high-efficiency binary transmission protocol based on the real-time streaming compression technology, and the abstract design is performed according to an application layer data structure and binary bidirectional conversion, and a corresponding processing class can be generated according to an IDL (intermediate definition file), thereby simplifying the conversion of binary data stream and the application layer data structure, and reducing the packaging and design complexity of a conventional binary protocol. Moreover, a three-level design is employed for the protocol,and a packet header + message base mode is employed, wherein the message base is taken as an abstract layer and is embedded into a third-level business message structure. Because most of intermediatetransmission layers just need to recognize the first-level and second-level messages, and do not need to recognize a specific third-level message, a high-efficiency binary transmission protocol whichis easy to extend can be implemented through the above layered design. Meanwhile, the universal compression design of the second-level message is performed. Compared with a conventional method, the method employed in the invention reduces the data transmission flow by 50%-80%.

Description

technical field [0001] The invention relates to a transmission protocol, in particular to a high-efficiency binary transmission protocol based on real-time stream compression technology. Background technique [0002] The securities market data is exported through the official data of the exchange, and snapshots are collected in a period of 3 seconds, and forwarded to a dedicated receiving program through a dedicated line, and finally merged, processed and distributed, and finally transmitted to the client program of the end user. With the vigorous promotion of the country The Internet + strategy has driven the popularization of high-speed broadband and mobile Internet, and the number of terminal devices has shown explosive growth, posing new challenges to the efficient and stable transmission of securities market data. [0003] Traditional securities market transmission generally uses custom binary codes based on the TCP protocol. With the popularization of the mobile Intern...
