A method and device for inter-process data interaction

Abstract

The invention belongs to the technical field of data communication, and specifically relates to a data interaction method and device between processes; the technical problem to be solved is: to provide a data exchange with a high degree of interaction that can realize free data interaction between multiple interactive processes Interaction method and device; the adopted technical scheme is as follows: S1. Establishing a data service process for controlling data interaction between multiple interactive processes; The data service process initiates a registration request; S3, the data service process registers, and establishes a corresponding virtual interaction service group according to the interaction flag; S4, multiple interaction processes with the same interaction flag perform data processing in the corresponding virtual interaction service group Interaction; S5. After the data interaction ends, the interaction processes participating in the data interaction respectively initiate a deregistration request to the data service process; S6. The data service process performs deregistration.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to a data interaction method and device between processes. Background technique [0002] At present, the data interaction between common processes mainly includes pipeline communication, shared memory communication and socket communication; [0003] For example: pipeline communication adopts half-duplex communication mode, data can only flow in one direction, can only carry unformatted byte stream and has defects such as limited buffer size; shared memory communication enables multiple interactive processes to directly access the same block Memory space, high efficiency; socket communication can be used for process communication between different machines; the above data interaction method is generally one-to-one interaction, does not support one-to-many or many-to-many data interaction, in the application of complex application requirements , the data intera...
