Information transmission method and system based on cloud service

Abstract

The invention provides an information transmission method and system based on a cloud service. The method comprises the steps that a push end is connected with an intermediary end based on the cloud service, and a file to be pushed is uploaded to the intermediary end; the intermediary end updates the first hash value table of a files stored in the intermediary end; a receiving end is connected with the intermediary end; the first hash value table is acquired from the intermediary end; the second hash value table of a file stored in the receiving end is compared with the first hash value table; an update file to be acquired is determined based on the comparison result; and the receiving end acquires the update file from the intermediary end. According to the invention, the public cloud service is used as a bridge to open up a firewall between enterprises of different network environments; a transmission path between the enterprises is established; one-way and two-way transmission in accordance with safety supervision in a variety of network environments can be realized; a file to be updated is determined through the updating of the hash value tables; the amount of data transmitted by a file every time is reduced; and the information transmission efficiency and stability are improved.

Description

technical field [0001] The present invention relates to the technical field of information transmission, in particular to a cloud service-based information transmission method and system that uses cloud technology to realize mass and efficient transmission of information between users. Background technique [0002] Today, with the increasingly developed Internet, information transmission between enterprises through the Internet is becoming more and more common, and the demand for information transmission between enterprises is also increasing. In order to ensure the security of communication between the enterprise and the outside world, a firewall is often added between the enterprise intranet and the external network. When transmitting information between enterprises, there may be many different firewalls, which require the cooperation of their respective IT departments to achieve Massive information transmission is time-consuming and labor-intensive. [0003] At the same ...

In order to ensure the security of communication between the enterprise and the outside world, a firewall is often added between the enterprise intranet and the external network. When transmitting information between enterprises, there may be many different firewalls, which require the cooperation of their respective IT departments to achieve Massive information transmission is time-consuming and labor-intensive

[0003] At the same time, enterprises may have different network environments. In a variety of network environments, there may be many problems in the transmission of massive information. For example, when transferring large files, errors of timeout failure are prone to occur, and the connection established between enterprises is disconnected. , In addition, the transmission rate of mass information transmission between existing enterprises is still greatly limited, which cannot meet the needs of users
