A coordinate input device detects coordinates of a position by indicating a screen of a display device with fingers of one hand, and transfers information of the detected coordinates to a computer through a controller. The computer receives an operation that complies with the detected coordinates, and executes the corresponding processing. For example, when it is detected that two points on the screen have been simultaneously indicated, an icon registered in advance is displayed close to the indicated position.

System and method for providing access to multiple wireless service providers (WSPs) on a shared network infrastructure. The system includes a plurality of access points (APs) coupled to a network which may be distributed in airports, mass-transit stations, businesses, etc. The network may couple to a wide area network, such as the Internet. Each AP may include a plurality of virtual APs (VAPs), each corresponding to a WSP. A portable computing device (PCD) of a user stores identification information indicating a WSP of a plurality of possible WSPs, and which may include an access level of the user. Each AP "listens for" or detects identification information associated with numerous WSPs. When the AP receives the identification information from the PCD, it determines the VAP / WSP for the PCD using the identification information. Network access is then provided to the PCD through the determined WSP at the determined access level.

A router for use in a network includes a scalable architecture and performs methods for implementing quality of service on a logical unit behind a network port; and for implementing storage virtualization. The architecture includes a managing processor, a supervising processor; and a plurality of routing processors coupled to a fabric. The managing processor has an in-band link to a routing processor. A routing processor receives a frame from the network, determines by parsing the frame, the protocol and logical unit number, and routes the frame to a queue according to a traffic class associated with the logical unit number in routing information prepared for the processors. An arbitration scheme empties the queue in accordance with a deficit round robin technique. If a routing processor detects the frame's destination is a virtual entity, and so is part of a virtual transaction, the router conducts a nonvirtual transaction in concert with the virtual transaction. The nonvirtual transaction accomplishes the intent of the virtual transaction but operates on an actual network port, for example, a storage device.
