Embodiment Construction

[0051] The application will be described in further detail below in conjunction with the accompanying drawings.

[0052] The embodiment of the present application provides a data transmission, a controller and an access device, which are used to solve the problem of delayed processing of the user's request caused by the limited processing capability of the controller in the prior art, causing the user to be unable to access the access device used by the user in time. Issues affecting user experience. Wherein, the method and the device described in this application are based on the same inventive concept, and since the method and the device have similar problem-solving principles, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0053] Hereinafter, some terms used in this application are explained to facilitate the understanding of those skilled in the art.

[0054] 1), the controller in the embodiment of...

Abstract

The invention discloses a data transmission method, a controller and an access device, so as to solve the problem that the limited processing ability of the controller in the prior art leads to delayed processing of a request of a user, and thus, the user can not timely access the access device. After the access device receives a Stelnet connection request, a SSH (secure shell) reverse tunnel establishment request is sent to a controller with the smallest load through a server; the controller sends an SSH reverse tunnel establishment response to the access device through the server, and the corresponding relationship among an interception port number, the IP address of the controller, the identity of the access device and the port number of the Stelnet port is stored to a database; and after an access request containing the identity of the access device is received through an interception port corresponding to the interception port number on the controller, the access request is forwarded to the Stelnet port of the access device through the interception port.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data transmission method, a controller and an access device. Background technique [0002] With the continuous development of communication technology, cloud technology emerges as the times require. The cloud can provide a lot of controller resources, so that users can rent cloud controllers to manage their own access devices, and realize users based on secure remote terminal protocol (secure telnet) , Stelnet) to access the access device used by itself. [0003] In practice, many users will rent the same controller to manage multiple access devices they use. The process for a user to access an access device based on Stelnet is usually: the user triggers the leased controller to The accessed access device sends a Stelnet connection request; after the access device receives the Stelnet connection request, it sends a secure shell (secure shell, SSH) reverse t...
