Multi-process communication registration method and device

Abstract

The invention provides a multi-process communication registration method and device, and the method comprises the steps that a shared memory is built after a process is started; the process actively broadcasts a registration message and waits for receiving a server message, and after the server is started, the shared memory is mapped and a query message is broadcasted; the process receives the query message; wherein the process responds to the query message and broadcasts a registration message, and the server responds to the registration message and registers the process. According to the scheme, the process can actively broadcast the registration message to trigger registration, so that the process can be timely added into a multi-process communication system to perform message communication under the condition that a new process exists, and the technical effect of efficiently performing multi-process communication in real time is achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multi-process communication registration method and device. Background technique [0002] Inter-process communication refers to the dissemination or exchange of information between different processes. Commonly used inter-process communication methods include: pipelines, message queues, semaphores, shared memory, and sockets. [0003] Among them, pipes are divided into: unnamed pipes and named pipes. Unnamed pipes can only be used for communication between processes with kinship relationships. Named pipes can exchange data between unrelated processes, but named pipes can only carry unformatted bytes. Stream, clear the data of the pipe when the data is read. The message queue can complete the work of passing messages between multiple processes, but its efficiency is low and its real-time performance is poor. The semaphore is used for inter-process synchronization. If you nee...

AI Technical Summary

Problems solved by technology

[0004] The most direct multi-process message communication method is to establish one-to-one communication between the two processes that need to communicate, which wastes resources and is not conducive to unified management

The commonly used multi-process message communication is implemented using socket, but the message transmission speed is slow and the real-time performance is not good

[0005] There is no effective solution for how to efficiently and real-time multi-process message communication
