Remote management method and remote management system

The present invention relates to remote management, and more particularly to a remote management method and a remote management system that are versatile and user-friendly.

A keyboard-Video-Mouse Switch (KVM Switch) is connected between the central control device and the plurality of controlled computers, so that the user can control multiple controlled computers through a central control device. . The central control device is usually composed of a set of keyboards, screens and mice.

The so-called Over-IP KVM is a multi-computer switch with a network interface that couples a client computer to one or more controlled computers via a network, so that the client computer The user can control one or more controlled computers through the network.

In the environment of the network type KVM switch, an additional client application is required on the client computer to view the image output by the controlled computer, otherwise the controlled computer cannot be operated, so the client application The program is generally called a Viewer.

Because this Viewer is an application, the type of this Viewer is related to the operating system of the client computer. At present, the operating systems on the market can be divided into two major categories, one for the Microsoft Windows operating system and the other for the operating system that is not a Microsoft Windows operating system. Manufacturers of networked KVM switches must provide different client applications for different operating system users. Users of the Microsoft Windows operating system need to install the client application (usually called Win Client) for the Microsoft Windows operating system on the client computer to view the image output by the controlled computer. Non-Microsoft Windows operating system operating systems (such as Linux), need to install a non-Microsoft Windows operating system client application, which is usually written in the Java language, so called Java Client. However, this Java Client still has to communicate with the operating system through a virtual machine. Therefore, if there is no applicable virtual machine, the client application written in Java language cannot be executed on the client computer.

When users want to change the network type KVM switch with handheld electronic devices and control one or more remote computers through management network type multi-computer switching, many problems are encountered as follows.

At present, virtual machines can be divided into J2EE (Java 2 Enterprise Edition), J2SE (Java 2 Standard Edition) and J2ME (Java 2 Platform Micro Edition) three levels, of which J2EE is suitable for servers; J2SE is suitable for personal computers; J2ME is applicable For handheld electronic devices (such as smart phones). As the name suggests, compared to J2EE or J2SE, J2ME can be regarded as a streamlined version of J2EE or J2SE. It is not a full-featured virtual machine and cannot support the aforementioned Java Client. Therefore, it is currently impossible to view the controlled computer with a handheld electronic device. The output image, of course, can no longer manipulate the controlled computer.

In addition, in the field of a KVM switch, a virtual media (Virtual Media) technology, such as that described in U.S. Patent No. 7,260,624 or U.S. Patent Publication No. 2007/0174526, is a physical storage device to which a first computer is physically connected. Mapping (such as a hard disk drive, a floppy disk drive, or a CD player) to a second computer via a network and a KVM switch, so that a virtual USB storage device can be obtained on the second computer, and It reads and writes. However, it must be noted that this virtual media technology still has its limitations. For example, in addition to the mapped (specific) storage device, the second computer cannot read (and cannot see) other unmapped ones on the first computer. Physical storage device. The second computer is also unable to transfer files between the storage device to which it belongs and any storage device of the first computer via the virtual media technology. For example, the first computer cannot move the file from other unmapped physical storage devices. Second computer. Moreover, when the second computer writes the virtual device shared by the first computer, the data is transmitted between the second computer and the first computer through the network, and the operating system of the second computer must continue when the data is moved. The file configuration table (FAT) of the mapped storage device is modified. Therefore, if the network connection is suddenly interrupted at this time, but the file configuration table has not been established yet, the storage device will be damaged. In addition, in order to have this virtual media function, the first computer still needs to install the above-mentioned client application, so for the above reasons, if you want to implement the virtual media function, it is not possible to replace this with a handheld electronic device. The first computer.

In addition, in the prior art shown in FIG. 1, a file transfer including uploading or downloading is possible between the client computer C and the specific server S connected to each other by the network N, but the user The end computer C cannot be filed by a server other than the specific server S, and the client computer C must additionally install an FTP client program, and the server S must execute an FTP server program. In addition, the file F downloaded to the client computer C cannot be automatically opened, and must be manually opened by the user. In addition, the above-mentioned client computer C cannot be replaced by a handheld electronic device because there is currently no universal FTP program suitable for all possible types of operating systems of the handheld electronic device.

On the other hand, a web browser is one of the necessary applications for a general personal computer or a handheld electronic device, and a personal computer or a handheld electronic device having a web browser becomes a web browsing device. If you can replace the aforementioned viewer (including Win Client or Java Client) with a web browser, you will be able to solve many of the above problems. That is, the manufacturer who can control the controlled computer via the network by the handheld electronic device can be realized, and the manufacturer who does not need to install the aforementioned viewer or network type KVM switch on the user terminal computer does not need to provide the foregoing.
