Duplex communication method based on FIFO (first in first out) named pipes and related equipment

Abstract

The embodiment of the invention discloses a duplex communication method based on FIFO (first in first out) named pipes and related equipment, so as to solve the problem that only half-duplex communication between processes can be realized when FIFO pipes are used in a Linux system in the prior art. The method in the embodiment of the invention comprises steps: an FIFO server receives a connectionestablishment request message sent by an FIFO client, wherein the connection establishment request message comprises the identity information of a first local named pipe of the FIFO client; the FIFO server establishes an FIFO session corresponding to the FIFO client based on the connection establishment request message; and in response to the connection establishment request message, the FIFO server sends the connection establishment request response message to the FIFO client through a second remote named pipe of the FIFO session, the connection establishment request response message comprises the identity information of a second local named pipe, the FIFO client can thus send information to the FIFO session through the first remote named pipe, and the first remote named pipe is a pipe corresponding to the second local named pipe in the FIFO client.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method for performing duplex communication based on a FIFO named pipe and related equipment. Background technique [0002] In the Linux system, data communication between processes can be realized by using a first-in-first-out (FIFO) pipeline. However, in the prior art, FIFO can only perform one-way data transmission, that is, only half-duplex can be realized. Duplex communication, the so-called half-duplex communication, can be understood as only sending or receiving data at the same time, but not sending and receiving at the same time. [0003] Therefore, how to use the FIFO to enable both ends of data communication to perform full-duplex communication, that is, to simultaneously transmit and receive data, has become an urgent problem to be solved. Contents of the invention [0004] Embodiments of the present invention provide a method for performing duplex ...
