Message transmission method and system, storage medium and computer device

Abstract

The invention provides a message transmission method for realizing the message transmission from the internal network to the external network through a queue. When a message is sent by using the method, when the message to be transmitted is placed into the transmission queue, a sending end detects that the message to be transmitted is put into the transmission queue, the message to be transmittedis read, and then the read message is sent to a receiving end through the pre-built transmission queue. The queue serves as a carrier for temporarily storing the message to-be-transmitted, so that thequeue can be resided on a memory or a magnetic disk. Therefore, when the sending end sends the read message to the receiving end, the message to be transmitted in the transmission queue is not deleted. The sending end determines whether the receiving end receives the message according to the feedback message returned by the receiving end, when the receiving end does not receive the message, the message to be transmitted is read again, and the re-read message is sent to the receiving end, so that the reliability transmission of the message is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a message transmission method, system, storage medium and computer equipment. Background technique [0002] Faced with the emergence of new types of network attack methods and the special needs of high-security networks for security, a network security technology with a new concept of security protection and prevention-"network isolation technology" emerged as the times require. The goal of network isolation technology is to ensure the isolation of harmful attacks, and to complete the safe exchange of data between networks outside the trusted network and on the premise of ensuring that the internal information of the trusted network is not leaked. [0003] When exchanging data between two (or more) trusted networks, the traditional technology usually uses a network security isolation device to cut off the penetrating TCP connection between the trusted networks, and ...

AI Technical Summary

Problems solved by technology

[0004] However, in the process of message transmission using network security isolation devices, data packets may be lost or incomplete. Therefore, how to improve the integrity of transmitted data has become a technical problem that needs to be solved urgently.
