1. ALL-IP Computer Architecture
The All-IP Computer Architecture is a technology which replaces the BUSes in existing computers with IP networks. The architecture realizes a flexible computer re-configuration environment regardless of the physical locations of the computing devices.
In an All-IP computer environment, each device has the TCP/IP protocol stack, and the devices are identified by their unique IP addresses. The devices are connected to Operating Systems running on the host computer. When the user utilizes other I/O devices attendant on the user movement, the new I/O devices register themselves to the Operating System. Then, the OS is able to display its outputs to the new display device according to the instructions from the new input devices at the current users location.
With the All-IP Computer Architecture, users are able to utilize the device-independent application environments continuously. Even when users are moving, they can leverage rich computing resources of supercomputers attached to the Internet with their cellular telephones, and after they get home, they can keep utilizing the same application environments with displays, keyboards and mouse devices in their study rooms.
All-IP Computer Architecture
In this demonstration system, we introduce an I/O device switch technology. This demo environment consists of two different networks; each network consists of two PCs providing displays, and one PC with a keyboard and a mouse device attached to it. Each device registers its IP address and the device type (keyboard, mouse, display) to the device information manager called "Rendezvous Manager (RM)".
In this demonstration, users carry small computers called "User Tag". When the users who need an I/O device group, keyboard, mouse and display, connect their User Tags to the network, the User Tags send the device request to the RM. In the real situation, User Tags could be users' cellular tphones or RFIDs. RFIDs contain the device configurations, and RFID readers proxy the device requests to the RM. Then the RM refers to the device information database to find available I/O devices, and shows the device group to the users. When a user moves to another location, the user attaches his or her User Tag to the network at the new location. After the RM assigns a new device group to the user, the user is able to continue his or her works on a same application environment as the previous location.

Key Technologies
USB IP
USB IP is a technology for exchanging USB data over IP networks. In the All-IP Computer Architecture, USB IP technology is utilized for controlling the Input devices such as keyboards and mouse devices.
Distributed Multihead X (DMX)
DMX is a proxy X server that provides multi-head support for multiple displays which are attached to different machines.
