Problems solved by technology
[0002] Under the SNA network system, when two systems use DPL mode for real-time data interaction, that is, when application systems use CICS middleware for cross-platform data interaction, because the transmission data length is long, the maximum interaction data length supports 24K, but the network Transmission efficiency is inversely proportional to the effective length of interactive data, and when the effective length is greater than 4K, the transmission efficiency decreases proportionally, resulting in poor network transmission performance and affecting business processing
[0003] Therefore, the transmission efficiency of interactive data under the existing SNA network system is low

Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0035] Before introducing the technical solutions provided by the embodiments of the present invention, first introduce the technical terms involved in the embodiments of the present invention:
[0036] 1. Mainframe, or mainframe, the English name mainframe, belongs to the large computer system. Mainframes use specialized processor instruction sets, operating systems, and application software. The term mainframe originally referred to a large computer system housed in a very large framed iron box to distinguish it from the smaller minicomputers and microcomputers. Most of the time it refers t...

The present invention provides a method and device for transmitting interactive data under the SNA network system, wherein the transmission method includes: detecting the start position and end position of the specified repeated character in the character string of the interactive data to be transmitted; position and end position, determine the character length of the specified repeated character; compress the interactive data to be transmitted according to the start position, type and character length of the specified repeated character; transmit the compressed interactive data. The above technical solution improves the efficiency of interactive data transmission under the SNA network system.
Description
technical field [0001] The invention relates to the technical field of data compression, in particular to a method and device for transmitting interactive data under the SNA network system. Background technique [0002] Under the SNA network system, when two systems use DPL mode for real-time data interaction, that is, when application systems use CICS middleware for cross-platform data interaction, because the transmission data length is long, the maximum interaction data length supports 24K, but the network The transmission efficiency is inversely proportional to the effective length of the interactive data, and when the effective length is greater than 4K, the transmission efficiency decreases proportionally, resulting in poor network transmission performance and affecting business processing. [0003] Therefore, the transmission efficiency of interactive data under the existing SNA network system is low. Contents of the invention [0004] The embodiment of the present...
