Abstract

The present invention relates to KVM switches that contain both remote and local ports and provide a user of the local port with a similar WEB based interface experience as that experienced by the remote user.

Claims

1. A keyboard, video and mouse (KVM) switch system comprising:

a KVM switch, said KVM switch being adapted to be coupled to a plurality of remote servers; and

at least one local workstation coupled to the KVM switch;

wherein said KVM switch includes;

a local port for connecting to said local workstation;

a control processor for running a web browser module and a web server module;

a video graphics processor coupled to the control processor for routing video; and

a local port video switch, wherein the local port video switch is coupled to the local port and the video processor and allows a local user access through said local workstation to a web-based interface that is resident in the control processor.

2. The KVM switch system of claim 1, further comprising an analog switch coupled to the local port video switch for routing analog video directly from one of said plurality of remote servers to the local port.

3. The KVM switch system of claim 1, wherein said at least one local workstation is a video display device, keyboard and mouse local console.

4. The KVM switch system of claim 3, wherein said web-based interface is a web page provided to said video display device of said local console provides a local user with functionality and administrative access to a remote server coupled to the KVM switch.

5. A keyboard, video and mouse (KVM) switch system, comprising:

a plurality of target interface ports, each of said target interface ports being adapted to couple said KVM switch system to a respective target device;

a network interface module adapted to couple said KVM switch system to a plurality of remote user client systems via a communications network, said remote user client systems each running a web browser application;

a local port coupling said KVM switch system to a video display device, keyboard and mouse local console, and

a control processor running a web server application for interaction with said web browser applications running on said remote user client systems, wherein;

said control processor further includes a web browser application, said web browser application interacting with said web server application to generate a web page; and

a video display processor for receiving said web page from said control processor and processing said web page into a video signal, and sending said video signal to said video display device of said local console.

6. A method for accessing a first keyboard, video and mouse (KVM) switch system having a plurality of target interface ports, each of said target interface ports being adapted to couple said KVM switch system to a respective target device, a network interface module adapted to couple said KVM switch system to a plurality of remote user client systems via a communications network, said remote user client systems each running a web browser application, a local port coupling said KVM switch system to a video display device, keyboard and mouse local console, and a control processor running a web server application for interaction with said web browser applications running on said remote user client systems, comprising the steps of:

running a web browser application on said control processor, said web browser application interacting with said web server application to generate a web page; and

receiving said web page from a video display processor of said KVM switch system, processing said web page into a video signal, and sending said video signal to said video display device of said local console.
