KVM switching system and its mouse synchronizing method

Abstract

The invention discloses a KVM switching system and the mouse synchronizing method. The system includes the console, the KVM switching device and the server. The console transfers the present cursor position to the KVM switching device that changes the cursor position into the mouse relative moving distance and transfers to the server. At the same time, it stores the consol position as the present server cursor position. In the system operation process, the storage server cursor position is returned to the console, which detects the cursor in-phase. If it is not in-phase, the present console cursor position will be transferred to the KVM switching device to make the server move the cursor position to the present console cursor position.

Description

technical field [0001] The invention relates to remote computer access technology, in particular to a KVM (Key, Video, Mouse, keyboard, display, mouse) switching system and a mouse synchronization method thereof. Background technique [0002] With the development of computer technology and network, the demand for centralized control of servers at the remote end is becoming more and more urgent. It is under this urgent demand that KVM technology emerges as the times require. KVM technology is a technology for remote control of servers. Its idea is to use a set of input / output devices, that is, a set of keyboards, monitors and mice, to realize complete control and management of one or more servers through the network. [0003] In existing computer systems, the mouse is used as a one-way computer input device, and the relative moving distance is usually used as a mouse parameter to be sent to the computer system, and the computer system moves the mouse cursor on the display rel...

AI Technical Summary

Problems solved by technology

However, in the existing KVM switching system, in order to ensure the real-time performance of data transmission, the KVM switching device and the client usually use a connectionless protocol for communication, such as UDP protocol and IP protocol, etc., while the connectionless communication protocol It is an unreliable transmission method, so abnormal situations such as data loss often occur

In the case of mouse operation data loss, the mouse of the console has moved, but the mouse cursor of the server operating system has not moved the mouse cursor due to abnormal conditions such as data loss, so that the two mouse cursors are no longer synchronized, and the console The operator sees two mouse cursors on the monitor

In this case, it is usually necessary to use a dedicated command provided by the KVM switching device to synchronize the mouse, and this operation is quite troublesome for the user.
