Method and apparatus for data interaction between processes

Abstract

The present invention belongs to the technical field of data communication, and particularly relates to a method and an apparatus for data interaction between processes. The technical problem to be solved is: providing a data interaction method and apparatus with a high interaction degree and capable of implementing free interaction of data among multiple interaction processes. The technical scheme comprises that: S1, a data service process is established for controlling data interaction among multiple interaction processes; S2, multiple interaction processes requiring data interaction initiate a registration request to the data service process respectively in a same interaction identifier; S3, the data service process performs registration, and establishes a corresponding virtual interaction service group according to the interaction identifier; S4, multiple interaction processes with the same interaction identifier perform data interaction in the corresponding virtual interaction service group; S5, after the data interaction ends, the interaction processes participating in the data interaction initiate a logout registration request to the data service process respectively; and S6, the data service process performs logout registration.

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...
