Descriptions can describe or contain document contents and layout. Some contents can be images and, instead of being included as image data in the description, can be image references. An image reference can be used to obtain an image, in the form of image data, from an image server. A printer can print the document after obtaining needed images from image servers. The image data often contains an image whose resolution does not match the resolution that the printer can properly print in the document. The image server can prepare image data with the correct resolution or can stream image data through a data connection to the printer in a hierarchical image format. A printer can receive a stream of hierarchically formatted image data until a desired resolution is reached and then simply close the data connection to cut off the stream of image data.

A system that stores sets of data blocks in extents located in storage devices is described. During operation, a receiving device receives, through an RPC framework, a first call asking to transfer an extent from a sending device to the receiving device. In response, the receiving device opens a port for a data connection that operates outside the RPC framework. The receiving device makes a second call, to the sending device through the RPC framework, asking to stream the extent to the port. The receiving device subsequently receives the extent from the sending device through the port and computes a checksum for the extent. The receiving device also receives a return from the second call, including a checksum for the extent computed by the sending device. If the computed checksum matches the received checksum, the receiving device returns the first call to indicate the transfer operation completed successfully.

The invention discloses a novel internet information acquisition exchange box, which comprises a mounting sheet, a bolt through hole, a clamping seat, a box body, a top cover, a rectangular sheet, a wiring groove seat, a slot, a protection structure, a switch and a restart button, and is characterized in that the protection structure is optimally arranged, and a network wiring penetrates through acircular through hole and then is in butt joint with the wiring groove seat; after wiring is finished, the clamping frame is inserted into the inner side of the slot to be clamped with the slot, so that the outer frame seat wraps the outer side of the wiring slot seat to protect the wiring slot seat, the gear clamps a network wire on the inner sides of the left clamping frame and the right clamping frame under the action of the upper rack and the lower rack by rotating the rotating rod, and meanwhile, the arc-shaped block is attached to the outer side of the circular port. And external dust is prevented from entering, so that network wiring and non-wiring empty slots can be protected, and the stability of data connection is ensured.

A wireless monitoring system comprises a remote monitoring center and a local monitor, wherein the monitoring center further comprises a monitoring station, a data backup server, a data analyzing server and a data receiving device.
