Abstract

Disclosed is a remote device management system for managing a plurality of remote devices (i.e., computers, servers, networking equipment, etc.) from one or more user workstations. The present invention discloses a scalable, multi-channel keyboard, video, and mouse (KVM) over Internet Protocol (IP) (KVMoIP) management system. The system can be used in a variety of configurations and is easily tailored to the user'"'"'s needs. The system also enables a user to remotely manage a variety of devices via a common user interface reached over a single IP address.

Claims

1. A method for remotely managing a plurality of remote devices by bi-directionally communicating information between at least one user workstation and at least two of the plurality of remote devices through respective remote interface modules, wherein said respective remote interface modules communicate via a common communications network with said at least one user workstation, said method comprising the steps of:

receiving a first plurality of signals comprising at least a first, a second and a third signal at one of the respective remote interface modules from its respective remote device;

converting said signals received at said one remote interface module into a format suitable for transmission via the common communications network;

transmitting said converted signals from said one remote interface module to said user workstation via the common communications network;

converting said transmitted first plurality of signals into a format suitable for use at said user workstation; and

receiving a second plurality of signals transmitted by said user workstation at each of said respective remote interface modules, the second plurality of signals including signals provided to said user workstation by a USB device in communication with said user workstation and received by said respective remote interface modules for simultaneous application of a bulk operation to said at least two remote devices by said respective remote interface modules.

2. The method according to claim 1, wherein said first plurality of signals include signals selected from the group consisting of video signals, audio signals, and peripheral device signals.

3. The method according to claim 1, wherein said second plurality of signals include signals selected from the group consisting of PS/2 signals, video output signals, USB signals, serial signals, IPMI signals and audio signals.

4. The method according to claim 1, wherein said common communications network comprises the Internet.

5. The method according to claim 4, wherein said signals received at said one remote interface module are converted into a format suitable for transmission via the Internet.

6. A method according to claim 3, wherein the second plurality include PS/2 signals or USB signals selected from the group consisting of keyboard signals and cursor control device signals.

7. The method according to claim 1, wherein the bulk operation is selected from the group consisting of rebooting of remote devices, applying software updates to remote devices, and detecting a diagnostic status of remote devices.
