US Patent:

20130179541, Jul 11, 2013

Filed:

Jan 6, 2012

Appl. No.:

13/344674

Inventors:

Joseph Yongxiang Chen - Englewood CO, US

Assignee:

COMCAST CABLE COMMUNICATIONS, LLC - Philadelphia PA

International Classification:

G06F 15/16

US Classification:

709219

Abstract:

A content delivery server may provide content to a requesting client device using a streamlined HTTP enhancement proxy delivery technique. For example, an HTTP proxy server may receive a request for video content or a fragment of video content from a client device. The request may be associated with a timeout scheduled to occur if no content has been received after a specified amount of time. The server may then transmit a request for the content to a remote server, such as an upstream cache server in the proxy server's CDN. When the proxy server receives a portion of the requested content from the remote server, the proxy server begins transmitting the portion to the client device before the requested content has been completely received and buffered. The client device may then begin receiving data from the proxy server before timeout has occurred.

International Classification:

US Classification:

39518204

Abstract:

The present invention provides a storage device array system and method for operating a storage device array system that provides for data transfers to and/or from a storage device array during the reconstruction of data contained in a failed storage device onto a spare storage device. One embodiment of the invention provides for data transfers during the reconstruction of data on the spare storage device onto a storage device that is replacing the failed storage device. Another embodiment of the invention is directed to the situation in which data contained in a storage device to which data can be written and from which data can be read but these operations are inhibited is being reconstructed on a spare storage device using other of the storage devices in the array. In this situation, write operations to the storage device array are conducted in a manner that provides fault-tolerance, i. e. , the ability to continue the reconstruction process, in the event one of the other storage devices being used to reconstruct the data on the spare storage device cannot provide the necessary data for reconstruction.

US Classification:

Abstract:

A process for determining the center of data disk tracks. The transducer head is positioned to one side of a track. The head repeatedly reads the track and microsteps across the track. The number of microsteps taken at the position on each side of the center of the track where a certain number of error correction code errors occur, are designated as boundaries of that track. The center of the track is then calculated as being half-way between the boundaries. By using the microstep off-sets for the centers of two tracks on a data disk, a correction factor can be calculated to compensate for thermal expansion of the data disk.
