Interprocess communication method and system

Abstract

The invention discloses an interprocess communication method and a system, wherein the method comprises: an interprocess communication (IPC) module of a client receives an instruction of initiating the connection sent by a client process, the corresponding relationship between an identifier of a pre-recorded server process and the address of a server is searched according to the identifier of the server process contained in the instruction of initiating the connection, and the address of the server is obtained; the IPC module of the client sends a connection message to the IPC module of the server according to the address of the server to request establishing the interprocess communication between the client process and the server process. The invention is adaptable to the demands of a distributed system and can timely and high-efficiently establish interprocess communication between the client process and the server process.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an inter-process communication method and system. Background technique [0002] Inter-process communication (IPC) originally refers to the communication between various processes within a device. With the continuous development of network technology, IPC is gradually developed and applied to distributed devices. A distributed device includes multiple service boards that are physically separated. Each service board has one or more independent CPUs. Each CPU is called a node, and programs running on the node are called processes. The client / server model is a typical IPC model. In this model, the processes of the communicating parties are the client process and the server process respectively. see figure 1 , figure 1 It is a schematic diagram of the structure and connection relationship between the client and the server in the prior art, the client process and the I...

Problems solved by technology

[0004] When the above-mentioned inter-process communication mode between the client process and the server process is applied to a distributed system, it will result in the inability to establish inter-process communication in a timely and efficient manner.

The specific reasons are as follows: First, when the DNS Server is a distributed device, due to the characteristics of the distributed device itself, the single board that DNS Server provides DNS services within a certain period of time is not fixed, and the single board may be reset at any time, causing customers The client process cannot obtain the address of the server in time, so it cannot establish inter-process communication in time; second, because the client process needs to search for the address of the server remotely before each time it initiates the establishment of an IPC connection, for a distributed system, it is very important for the system to find the address. is too expensive to efficiently establish interprocess communication
