Description

System, device and method for virtualizing self-carrying technology

The present invention relates to a self-carrying technology, and in particular to an innovative self-contained device, system and method.

In the early prior art, the Virtual Network Computing (VNC) was controlled by the network control architecture, and any computer (slave, client) on the network was used to control the remote computer or server (master). Server). The main computer and the attached computer are placed in two different places, and connected by the network. The picture (or graphics) transmission of the two computers is also completed by the network. However, the shortcomings of VNC are: distance limitation, limitation of network bandwidth, reduced resolution of the screen, and blocking of the firewall, etc., which have caused VNC applications to be limited. For this reason, many softwares or architectures have been developed, and the list is too numerous to Extend the application of VNC to stabilize signals and improve convenience.

For business people or engineers with frequent business trips, carrying a laptop computer for travel to another place can replace the defect of VNC remote control software. However, when returning to the company headquarters, it must be manually All changes in the work content are synchronized to the specific computer host of the company headquarters, which causes a lot of inconvenience.

High-tech has become inseparable from everyday life, and it has also penetrated into enterprises. IT consumerization not only improves work productivity and efficiency, but also reduces IT costs. With the popularity of smart devices and the rapid development of network technologies, smart devices have become "Bring your own devices (BYOD)", employees are able to carry devices to the workplace at any time, and save them through the Internet. Take the files or materials in the company, so that employees can perform official duties at other places at any time to improve productivity and efficiency.

In the prior art, BYOD is mostly a portable computing device (such as a notebook computer or a tablet computer) designated by the enterprise. However, the portable computing device may be different from the computer used in daily work in the operating environment because of the portable type. The computing device may have different operating systems and applications than the computer used for daily work. In addition, BYOD also brings doubts about information security, because BYOD's own wireless networking capabilities (such as WiFi or Bluetooth) may not be controlled by the company. In order to balance BYOD and the information security of the enterprise itself, companies may have to introduce BYOD monitoring technology. For companies that are allowed to use BYOD, this will be a new challenge and expense.

In other words, the virtual file system 103 is equivalent to the first host host file system 1022. The relationship between the first host host file system 1022 and the virtual file system 103 can be compared to "the deity and the avatar". "." In the continuation, the virtual file system (the avatar) 103 executes a virtual machine function (virtual operation and its function) on the second host host 104 through the virtual machine module 1064. In an embodiment, when the external device 106 is transferred from the first host host 102 to the second host host 104, the operating system, application or data file belonging to the first host host 102 stored in the memory unit 1062 ( The virtual file system 103 generates a virtual file system 103 through the virtual machine module 1064. The virtual file system 103 also performs virtual operations and functions on the second host host 104 through the virtual machine module 1064. In other words, the first The hardware computing capability of the second host host 104 is to execute the virtual file system 103 of the first host host 102 stored in the memory unit 1062.

For example, in the virtualization self-carrying system described in claim 7, the virtual machine module clones the file system of the first host host to generate the virtual file system. For example, in the virtualized self-carrying system described in claim 7, the operating system of the virtual file system is the same as the operating system of the first host host, and at least one application of the virtual file system (application) ) at least one application identical to the first host. For example, in the virtualized self-carrying system described in claim 10, the virtual machine function includes: the virtual file system operates editing, deleting, copying, and the like on the second host host. The virtualized self-carrying system of claim 7, wherein the external device comprises a universal serial bus. A virtualized self-carrying device, the device comprising: at least one memory unit storing a file system of a first host host; a virtual unit generating a virtual file system, executing a virtual machine on a second host host (Virtual Machine a function; and a synchronization mechanism to record the virtual file system on the second host. For example, the virtualization self-carrying device described in claim 13 of the patent scope includes a distributed version control system (DVCS). For example, in the virtualized self-carrying device described in claim 13, the virtual unit clones the file system of the first host host and generates the virtual file system. The virtualized self-contained device of claim 13, wherein the virtual file system has the same operating system as the first host host, and at least one application of the virtual file system is identical to the first host. At least one application of the host. For example, in the virtualized self-carrying device described in claim 16, the virtual machine function includes: the virtual The virtual file system performs editing, copying, deleting, and the like on the second host. The virtualized self-carrying device of claim 13, wherein the device comprises a universal serial bus.
