Method for a network encapsulated USB

Disclosed is a method for a network encapsulated USB. Benefits include improved functionality.

Background

              PC expansion buses such as USB and 1394 enable devices to be attached to a computer. The devices include:

·        Printers

·        Scanners

·        Keyboards

·        Mice

·        Audio speakers

·        Web cameras

·        FLASH RAM drives

·        Digital cameras

·        Digital video camcorders

              For devices such as drives and printers, well-defined protocols exist for sharing these devices on a network. Anyone with the proper permissions on the network has access to these devices. However, for other types of devices, no a standard protocol enables the sharing of the device.

              Conventionally, sharing images and video requires the user to copy the content, and then share the files in some manner, such as via a webpage or folder with file sharing enabled. 

              A requirement exists for a flexible, extensible method that enables the sharing of devices that are attached to a PC. This method should support devices that exist today as well as those that are yet to be invented without the need for extensions to the protocol.

General description

              The disclosed method enables PC-attached peripheral devices to be shared on a LAN or the Internet by encapsulating the PC bus commands within a network protocol, such as TCP/IP.

Advantages

              The disclosed method provides advantages including:

·        Improved functionality of peer-to-peer device sharing in a simple manner

Detailed description

              The disclosed method is the encapsulation of the native bus commands of a PC expansion bus, such as USB or 1394, within a network protocol, such as TCP/IP. This functionality enables devices attached to these bus types to be shared with any other system with proper permissions that are on the same network such as a LAN or the Internet (see Figure 1).

              By encapsulating the native protocol of the expansion bus, a tunnel is create...
