Mouse synchronization process, system and server

Abstract

The embodiment of the invention discloses a mouse synchronization process, system and server. The mouse synchronization process includes: receiving data packets transmitted from a Keyboard Video Mouse (KVM) client carrying mouse position information of the KVM client PC system; comparing the mouse position information of the KVM mouse with the mouse position information of the KVM client PC system, and adjusting the position of the KVM mouse according to the result. The embodiment of the invention can realize an accurate, quick and automatic mouse synchronous effect; and the embodiment of the invention can realize mouse real-time synchronization, both fore and after the server entering into the operating system, therefore operations at the KVM customer client can be convenient and simplified, and the customer client will be more friendly. Furthermore, the embodiment of the invention adopts network to transmit KVM mouse data, thereby having a good KVM mouse synchronizing effect.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a mouse synchronization method, system and server. Background technique [0002] In the KVM (Keyboard Video Mouse, multi-computer switcher) application of the server, it is necessary to send the mouse movement of the remote KVM client to the server, simulate it as the mouse of the server, and realize remote control, and use the KVM mouse on the remote client Controlling the server is one of the important contents of KVM. [0003] Usually, the data flow direction of the KVM mouse is like this: the KVM client captures the mouse action of the local PC (Personal Computer, personal computer), and sends it to the SMM (ShelfManage Module, machine) through the LAN (Local Area Network, local area network) after it is encapsulated. frame management board) board, the SMM board sends the data packet to the BMC (Baseboard Manage Controller, single board ma...

AI Technical Summary

Problems solved by technology

Before entering the operating system, the BMC cannot obtain parameters such as the pointer movement accuracy and speed of the mouse on the server operating system

[0012] However, the existing synchronization methods are based on the premise that the USB device does not lose frames, and are only used to solve the mouse out-of-sync problem caused by network frame loss; To additionally carry KVM keyboard and mouse data packets, due to the limited bandwidth of the IPMB bus, the effect of KVM is not good, and the speed of mouse synchronization is relatively slow

In addition, since this method needs to additionally configure mouse working parameters in the operating system, mouse synchronization cannot be achieved before the server enters the operating system interface, which also makes this method more cumbersome

Moreover, mouse synchronization requires customer participation, using the synchronization button, customer experience is not good
