Data stream fusion efficient transmission method based on one-way optical shutter

Abstract

The invention discloses a data stream fusion efficient transmission method based on a one-way optical shutter, and belongs to the technical field of one-way optical shutter information transmission. Comprising the following steps of dividing a data stream into an isomorphic data stream and a heterogeneous data stream before performing unidirectional transmission on the data stream by using an optical shutter; performing protocol stripping on the source data packet according to the data stream type to generate a data packet queue, and recording a data packet sequence number and a corresponding task ID; different data packet queues adopt different decision strategies to fuse the data packets; the fused data packet queue is packaged by using a one-way optical shutter transmission packaging protocol; sequentially adding the packaged data packets into a sending queue channel, and sending the packaged data packets to the inner end of a one-way optical shutter through one-way transmission; and the data packets at the inner end of the optical shutter are unpacked, restored and repackaged, and are sequentially sent out from the inner network end of the optical shutter, so that the efficient transmission task of the data stream is completed. According to the invention, a data packet fusion strategy is adopted, and the streaming data is fused in an optimal mode according to different streaming transmission scenes, so that the transmission efficiency is improved.

Description

technical field [0001] The invention relates to a safe and efficient transmission method for data flow of a one-way shutter, in particular to a data flow fusion and high-efficiency transmission method based on a one-way shutter, and belongs to the technical field of one-way shutter information transmission. Background technique [0002] With the rapid development of communication technology and network technology, the computer information construction of government agencies, enterprises, institutions, and organizations has been comprehensively promoted, but there have also been many network security problems, such as floods, interception, Forgery, viruses, loopholes and other network attack methods emerge in endlessly on the Internet, and the direct loss caused is that the occurrence of data leakage and data theft seriously endangers security, social stability and public interest. Therefore, using one-way optical shutters to transmit data between classified networks and non-...

Problems solved by technology

[0003] The full name of the optical gate is the one-way isolation optical gate system. The problems in the prior art mainly focus on the efficiency and reliability of the one-way transmission. Because the premise of the one-way transmission is that there is absolutely no dark return channel, the data packet After sending, it is impossible to know whether the peer end has actually received the message

[0004] The usual way to solve this problem is to sacrifice part of the bandwidth for multiple data packet transmissions or add redundancy to reduce the unreliability of one-way transmission, but the bandwidth loss caused by this is in the case of large traffic transmission The effect is more pronounced under
