Method for implementing high-available switching device cascade connection

Abstract

The invention provides a method for realizing the cascade connection of a high availability switcher. The method taking a matrix switcher as the core realizes the transmission quality of a system signal through a switching module and a standard switcher by the point-to-point access between a star topology mixing cascade connection and a matrix switcher as well as the star topology mixing cascade connection and the standard switcher. The steps of the realization of the method is as follows: a matrix switcher is taken as the core device, one end of the core device is connected with a keyboard, a mouse and a display through the switching module for the system monitor and control, the other end of the core device is connected with the standard switcher through the switching module, the standard switcher is also connected with computer equipment to be switched to support the switch of 512 computer equipment. Compared with the method of the standard switcher to realize the extension of the switcher through the series cascade connection, the method of the invention has the characteristics of the higher usability of the system and the better transmission quality of the signal.

Description

Technical field [0001] The present invention relates to the field of computer communication technology, in particular to a method for realizing high-availability switch cascade. Background technique [0002] The switch is also known as KVM, which is an abbreviation for Keyboard, Video, and Mouse. The core idea of ​​KVM technology is to realize centralized management of system and network and provide manageability through proper keyboard, mouse, and display configuration, improve the efficiency of system administrators, save the area of ​​computer room, and reduce network engineering and servers. The total cost of ownership of the system, avoid the radiation generated by the use of multiple displays, and build a healthy and environmentally friendly computer room. With the KVM multi-host switching system, you can switch between multiple hosts or servers with different operating systems through a set of KVM. [0003] The most common switcher system uses a three-in-one cable for keyb...

AI Technical Summary

Problems solved by technology

However, the serial cascading method of the standard switch will bring the disadvantages of low system availability, and the signal transmission quality will weaken with the expansion of the system scale.

If the matrix switcher system is used to expand the system scale, although the above problems can be solved, the high cost of the system will seriously affect its application and promotion
