Access to content addressable data over a network
Access to content addressable data on a network is facilitated using digital information storing devices or data repositories (“silos”) that monitor broadcast data requests over the network. A number of silos automatically monitor both data requests and data itself that are broadcast over a network. The silos selectively store data. Each silo responds to data requests broadcast over the network with data the silo has previously intercepted. A content addressable file scheme is used to enable the data repositories to reliably identify data being requested. When a data request is received, each silo evaluates whether it has all or a portion of the data being requested and responds to requests when it has the data. Requests for data are implemented by broadcasting a cryptographic hash data identifier of the data file needed. The data identifier is used by a silo to determine which data to receive and store. A silo includes a network interface, a digital asset collector, an asset request list, asset storage, an asset identifier processor and an asset supplier. The asset identifier processor computes a cryptographic hash asset identifier for a received asset and compares it to an asset identifier on its asset request list to verify it has the correct asset. A hash of a list of assets is also computed and broadcast over the network. When the hash of the list of assets is received by a silo, it places all the assets in its asset request list.

A warning system evaluates the historical data in the data log to identify one or more devices that have a soft failure condition, wherein an alarm is output for each soft failure identified. A display module combines the historical data from the data log and one or more alarms from the warning system into a single display for review.
Exception raised notification
An exception notification system is described herein that provides an early notification that a software exception has occurred before exception handling code has run. The exception notification system receives a registration request from program code to register a handler to receive an early notification when an exception occurs. When an exception occurs, the system raises an event that calls each registered handler. After the handler returns, the system performs normal exception handling, so that the early notification does not change existing exception-handling behavior. The exception notification system allows a program to inspect and log an exception before the program state has been modified by exception handling. The program code can capture detailed information about the cause of the exception to enable further offline analysis. Thus, the exception notification system allows developers to improve their programs by receiving more information about unexpected conditions in the program code.

Method for fast, secure 802.11 re-association without additional authentication, accounting, and authorization infrastructure
A method wherein an access point authenticates itself with neighboring access points and establishes secure and mutually authenticated communication channels with its neighboring access points. When an access point learns of a neighboring access point, it initiates an authentication with an authentication server through the neighboring access point. Once access points have mutually authenticated each other, whenever a station authenticates itself with a first access point, the first access point communicates the station's authentication context information, for example session key and session identifier, to each neighboring access point. Thus, when the station roams to a neighboring access point, the neighboring access point presents the station with a reauthentication protocol, for example LEAP reauthentication, and if the reauthentication is successful, communication between the station and the neighboring access point takes place immediately and no new EAP authentication needs to occur.

So, logical unit devices can be consolidated and reconsolidated to single physical volumes and other physical volumes without requiring changes to the operating system or its application software and without requiring application or host downtime.
Preventing data loss in a storage system
Storage servers use a fast, non-volatile or persistent memory to store data until it can be written to slower mass storage devices such as disk drives. If the server crashes before a write can complete, the data remains safely stored in non-volatile memory. If the data cannot be committed to disk when the server reboots (e.g. because the destination mass storage device is unavailable), it is stored in a file. When the disk reappears, the data in the file may be used to restore a file or file system on the disk to a consistent state.

A system controller is presented that controls an output format of data according to a data congestion status of the data and then outputs the data over an output bus. Specifically, if there is data congestion, the system controller changes the format of the data to a format that matches a bus width of the output bus before outputting the data over the output bus. To give a specific example, the system controller changes the format of the data input over an input bus in an input format of 4 B to an output format of 5 B before outputting the data over the output bus. If there is no data congestion, the system controller outputs the data over the output bus without changing the input format.

Synchronizing clocks in an asynchronous distributed system
The present invention extends to methods, systems, and computer program products for synchronizing clocks in an asynchronous distributed system. Embodiments of the invention facilitate creation of a trustable and practical common time (time of day) reference across a set of peer nodes (observers), such as, for example, members within a common asynchronous (distributed) system.

The host interface is isolated from the attached storage devices, for example IDE disk drives, so that the actual attached drives are not limited in number or interface protocol. Various device ports can be implemented, and various RAID strategies, e.g., level 3 and level 5, can be used. In all the cases, the host interface provides a standard, uniform interface to the host, namely an ATA interface, and preferably a dual channel ATA interface. The host interface emulates the ATA single or dual channel interface and emulates one or two attached IDE devices per channel, regardless of the actual number of devices physically connected to the controller. Thus, for example, five or seven IDE drives can be deployed in RAID level 5 protocol without changing the standard BIOS in a PCI host machine. Thus the RAID controller is transparent relative to a standard dual channel ATA controller board.

A dilation image is generated from an original digital image utilizing a processing image (b) and a target image (T), where each pixel in the target image is processed in parallel. The process entails, for each target pixel, i) determining coordinate values for the target pixel, ii) determining a surrounding pixel area for the target pixel, iii) and processing each pixel in the surrounding pixel area to determine whether or not to updated the value of the target pixel. In processing each surrounding pixel, a determination is made whether the pixel has a value of 1. If not, then the next surrounding pixel is processed. If so, then a determination is made which pixel element of the structuring element overlays the target pixel, and whether that pixel has a value of 1. If so, then the value of the target pixel is updated. If not, then the next pixel in the surrounding pixel area is processed. Once the target pixel has been updated one time, the processing of the remaining surrounding pixels is terminates. If processing of all surrounding pixels results in no update to the target pixel, then the target pixel is not updated. After all target pixels have been processed, the resultant image is output as the dilation image.

Methods, techniques and apparatus identify members and characteristics of binders and/or other groups of communication lines such as those in a DSL system. Information obtained includes the identification (for example, by scanning) of significant crosstalking “offenders” and their “victims” that are affected by the crosstalk. One or a small number of modems are instructed to transmit with preselected transmit spectra, after which evidence of crosstalk in the noise spectrum data is examined for potential victim lines. Direct evidence of noise spectrum contribution by a suspected offender line may be obtained by collecting reported noise spectrum data and/or estimated noise spectrum data from potential victim lines. Also, where such direct evidence is not available, or in addition to it, other operational data showing crosstalk interference relating to potential victim lines can be used. The transmitting modem can either be on the CO/RT side or on the CPE side. Modems other than suspected offenders might transmit zero or minimal power in one or more selected frequency bands during scanning to reduce the risk that a modem and/or line not being examined for “offender” status supplies unnecessarily complicating and/or dominant crosstalk during the procedure. For DMT modulated DSL transceivers, well designed transmit spectra can be easily enforced by manipulating line profiles where such well designed line profiles cause minimal or no interruption to existing DSL customers. The invention also can be used to identify (partially or fully) the absolute values of crosstalk channels making up a channel transfer function.
