Data transmission device and system

Abstract

The invention relates to a data transmission device and a system thereof. The data transmission device comprises a host computer component and a virtual terminal, wherein, the host computer component is used for obtaining the host computer information; the virtual terminal is used for receiving the host computer information and obtaining the operating instruction which is sent to the host computer specified by the host computer information. The data transmission system comprises the data transmission device, a browser and a host computer, or a user interface device and a host computer, wherein, after receiving the trigger request of the browser or the user interface, the host computer component in the data transmission device obtains the host computer information; the virtual terminal transmits the obtained operating instruction to the host computer instructed by the host computer information. The embodiment of the invention realizes the data transmission by the host computer component and the virtual terminal, can transmit the data in no agency and in mass and improve the expansibility.

Description

technical field [0001] The invention relates to computer network technology, in particular to a data transmission device and system. Background technique [0002] With the continuous development of network technology, more and more projects are involved in the data update of the host. In order to reuse the previous project and reduce code, it is necessary to build a data transmission device, so that programmers can focus on project development and improve work efficiency. With the maturity of various programming languages ​​and the wide application of various network protocols, such as telnet protocol, ssh protocol, file transfer protocol (File Transfer Protocol, hereinafter referred to as FTP), secure file transfer protocol (Secure File Transfer Protocol, hereinafter referred to as SFTP), Data transmission devices are also constantly being improved. [0003] A data transmission device in the prior art is a desktop single-computer installation and upgrading device, which is...

Problems solved by technology

This kind of device can realize batch operation, but because the device needs to deploy the agent to the host, if the agent is not running on the host for a long time, then before each installation and upgrade operation, it is necessary to deploy the agent to each host, and the installation and upgrade operation is completed Finally, it is necessary to uninstall the agent, which is undoubtedly a waste of time and meaningless; moreover, in order to ensure the normal operation of the business in the telecommunications field, most of them are in the form of a single or dual-machine cluster network. In this case, it is up to the business to judge whether the environment is correctness, whether the installation / upgrade operation is carried out, etc., but the device focuses on the concept of software distribution and can realize validity detection, but the business side is rarely involved, which makes it difficult to apply the device to the telecommunications field and limits the scope of use; in addition, the Most of these devices are mainly based on the Graphics User Interface (GUI), and only the host with the server installed can perform the installation / upgrade operation, which lacks flexibility.
