Technology for cloud service to access data of Intranet

Abstract

The invention provides a technology for cloud service to access data of Intranet. In the technology, a server side and a client are used, wherein the server side is placed at a cloud service center under the Internet environment, the client is placed in a local area network, a control channel is established by the client and the server side firstly, and then opening of a data channel is controlled through the control channel; when an application under the environment of the server side needs to actively access an application under the environment of the client, the server side sends a message to the client through the control channel firstly, after the client receives the message, the client actively establishes a TCP (Transmission Control Protocol) data connection channel to the server side, and then the server side utilizes the data channel to transmit the specific application data. The technology solves a problem in the prior art and achieves accessing of the local service through Internet or mobile Internet, and meanwhile, the data security is guaranteed; the technology can be applied to remote monitoring systems of medium-sized and small enterprises, and the functions can be realized for some small enterprises through installing a Qiyuntong product on a video server in the local area network only.

Description

technical field [0001] The invention relates to the technical field of network data transmission, in particular to a technology for cloud services to access intranet data. Background technique [0002] With the development of cloud computing, the application systems of enterprises and institutions are gradually deployed to large-scale computing centers, and some of the original systems of these units cannot be migrated to the computing centers for some reasons, but the applications built in the technology centers need to be integrated with these old systems Data exchange, especially when the computing center actively accesses the old systems inside the unit. These old systems are generally placed in the local area network. Due to the shortage of IP addresses, there may be no fixed IP. In this case, it will be troublesome for the computing center to access the old systems. [0003] At present, many enterprises use the peanut shell service to solve the problem of mutual access...

[0002] With the development of cloud computing, the application systems of enterprises and institutions are gradually deployed to large-scale computing centers, and some of the original systems of these units cannot be migrated to the computing centers for some reasons, but the applications built in the technology centers need to be integrated with these old systems Data exchange, especially when the computing center actively accesses the old systems inside the unit. These old systems are generally placed in the local area network. Due to the shortage of IP addresses, there may be no fixed IP. In this case, it will be more troublesome for the computing center to access the old systems

[0003] At present, many enterprises use the peanut shell service to solve the problem of mutual access between the company's intranet and the Internet. The peanut shell can meet the needs of some enterprises to a certain extent, but for some small and medium-sized enterprises in the local area network, it is necessary to perform port mapping on the router. In addition to the complexity of configuration, some enterprises have no management rights to routers at all, so they cannot use peanut shell services.
