Abstract: An improved remote USB access method allows a local host to access USB devices on a remote host in a manner that reduces network traffic in certain situations. When the local host copies a file from a USB device A to a USB device B both located on the remote host, the operation is initially handled in a conventional manner by which data is transferred from device A to the local host over the network, and then from the local host to device B over the network. The remote host is provided with an ability to detect such an operation as a special case where the data transfer from the local host to device A is unnecessary. Thus, the remote host copies the data from device A to device B, and notifies the local host to stop the network data transfer from the local host to device B.

Abstract: The present invention introduces the notions of a rendezvous component and rendezvous functionality into the communications network environment. Using the invention, an application can express information regarding when an operation requested of a device should complete and at which location, and it enables the device to perform its operations respecting this information while also improving the device's overall behavior. In an embodiment, one or more data objects are distributed across one or more collections of storage devices using a dispersal technique. When access to a data object is desired, a rendezvous component issues a set of constituent requests to the collections of storage devices. These requests typically include location and timing rendezvous parameters specifying a destination location where and a given time when a given data object is to be reconstituted.

Abstract: A DMA controller controls DMA transfer in an information processing system. Input and output devices are a transfer source or a transfer destination in DMA transfer and request DMA transfer. A DMAC activating unit is provided with an event monitoring unit and an event register. The event register registers an event subject to monitoring. The event monitoring unit detects an event generated in the input and output devices and determines whether the detected event matches an event registered in the event register. If it is determined that the events match, the event monitoring unit activates the DMA controller.
