A digital data file storage system is disclosed in which original data files to be stored are dispersed using some form of information dispersal algorithm into a number of file “slices” or subsets in such a manner that the data in each file share is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other file shares. These file shares are stored on separate digital data storage devices as a way of increasing privacy and security. As dispersed file shares are being transferred to or stored on a grid of distributed storage locations, various grid resources may become non-operational or may operate below at a less than optimal level. When dispersed file shares are being written to a dispersed storage grid which not available, the grid clients designates the dispersed data shares that could not be written at that time on a Rebuild List. In addition when grid resources already storing dispersed data become non-available, a process within the dispersed storage grid designates the dispersed data shares that need to be recreated on the Rebuild List. At other points in time a separate process reads the set of Rebuild Lists used to create the corresponding dispersed data and stores that data on available grid resources.

A system and method for searching information from a database using a natural language. In one embodiment, the system analyzes a natural language search request and converts the search request into one or more search words. The search words are further converted into a string of bytes, and a subset of a target database, referred to as the datasoup, is searched. If there is a match between the bytes and raw data in the datasoup, the searched data is retrieved from the target database. The searched data is then formatted and provided to a user. Optionally, the searched data can be provided to the user unformatted. In another embodiment, the system includes a system server configured to receive a natural language search request, a core engine coupled to the system server and to the target database, and a system database coupled to the core engine, where the core engine accesses the system database to analyze the search request. The system database stores global rules, one or more preference files, and one or more dictionaries, and the preference file stores information about the user.

Network data files are secure through the operation of an infrastructure gateway-based network file access appliance. Network file data, corresponding to network pocket payload data, are further reduced to a sequence of data blocks that are secured through any combination of block encryption, compression, and digital signatures. File meta-data, including encryption, compression and block-level digital signatures are persistently stored with the file data, either in-band in the file as stored or out-of-band key as a separately stored file or file policy record. File meta-data is recovered with accesses of the file data to support bidirectional encryption and compression and to detect tampering with the file data by comparison against block-level digital signatures.

The Shared Internet Storage Resource provides Internet-based file storage, retrieval, access, control, and manipulation for a user. Additionally, an easy-to-use user interface is provided both for a browser or stand-alone application. The entire method provides means by which users can establish, use, and maintain files on the Internet in a manner remote from their local computers yet in a manner that is similar to the file manipulation used on their local computers. A high capacity or other storage system is attached to the Internet via an optional internal network that also serves to generate and direct metadata regarding the stored files. A web server using a CGI, Java(R)-based, or other interface transmits and retrieves TCP / IP packets or other Internet information through a load balancer / firewall by using XML to wrap the data packets. File instructions may be transmitted over the Internet to the Shared Resource System. The user's account may be password protected so that only the user may access his or her files. On the user's side, a stand-alone client application or JavaScript object interpreted through a browser provide two means by which the XML or other markup language data stream may be received and put to use by the user. Internet-to-Internet file transfers may be effected by directly downloading to the user's account space.

This invention is related to content delivery systems and methods. In one aspect of the invention, a content provider controls a replacement process operating at an edge server. The edge server services content providers and has a data store for storing content associated with respective ones of the content providers. A content provider sets a replacement policy at the edge server that controls the movement of content associated with the content provider, into and out of the data store. In another aspect of the invention, a content delivery system includes a content server storing content files, an edge server having cache memory for storing content files, and a replacement policy module for managing content stored within the cache memory. The replacement policy module can store portions of the content files at the content server within the cache memory, as a function of a replacement policy set by a content owner.

In a memory system with a file storage system, a scheme for allocating memory locations for a write operation is to write the files substantially contiguously in a memory block one after another rather than to start a new file in a new block. In this way, they are more efficiently packed into the blocks by being written contiguously one after another. In a preferred embodiment, an incrementing write pointer points to the write location in memory for the next data for a file, which is independent of the offset address of the data within the file. When a current write block becomes filled with file data, an erased block is allocated, and the write pointer is moved to this block. Similarly a relocation pointer is used for data relocation during garbage collection or data compaction operations.

Cookie files received from cookie file sources (e.g., Internet websites) are screened based upon the recommendations of a service provider which downloads privacy protection criteria in the form of a “watch list” to a subscriber's client machine. A user-friendly interface allows the subscriber to optionally modify the watch list prior to it being used at the subscriber's client machine by assigning known cookie file sources to either a “trustlist” or a “blacklist.” A “composite list” is then generated and used by the client machine to screen cookie files. The subscriber receives updates from the service provider on either a periodic or “as-needed” basis using a “quick update algorithm.” A “privacy scanning algorithm” runs on the client machine and has two different modes of operation. The first is a continuous mode where unwanted cookie files are blocked from being stored at the client machine. The second is a periodic mode where the client machine is “scrubbed” of unwanted cookie files according to the privacy protection criteria.

A multi-user file storage service and system enable each user of a pre-subscribed user group to communicate with a remote file server node via a wide area network and to access the files of the file group via the respective client node. More than one user of the pre-subscribed user group is permitted to access the file group at the remote file server node simultaneously. Integrity of the files at the remote file server node are maintained by controlling each access to each file at the remote file server node so that each access to files at the remote file server is performed, if at all, on a respective portion of each file as most recently updated at the remote file server node. Additionally, an encrypted key is transferred from the file server node to a particular client node via a secure channel. The encrypted key uses an encryption function and a decryption function not known locally at the remote file server. Furthermore, both privileged access control rights and file sharing mode access control to a particular file of the group of files are delegated to one or more distributed nodes other than the remote file server node which provides the data.

Data is now able to be transferred back and forth between computer systems which have disparate file systems, e.g., between a computer having a hierarchical file system and a computer having a nonhierarchical file system. The differences, however, are not limited to the file storage system. Data may now be transferred across different platforms, different human and computer languages, different binary codes, etc. From one computer system the associated metadata is stored in a interpretable format on the second computer system so that when data and its associated metadata are transferred, the second computer system can interpret the transferred data. Data transfer can be accomplished in both directions. Thus, a tool writer or a software developer using a integrated development environment, such as Eclipse, on a Linux workstation with its hierarchical file system may download source files and other resources from an iSeries computer server with its OS / 400 nonhierarchical file system, modify the resources, and then put them back onto the iSeries machine for use on the iSeries. The metadata of the source file and other resources are stored in a .properties file which, if in XML format, supports the transfer of resources across the Internet.

A multi-user file storage service and system enables each user of a user group to operate an arbitrary client node at an arbitrary geographic location to communicate with a remote file server node via a wide area network. More than one user of the user group is permitted to access the file group at the remote file server node simultaneously, but the integrity of the files is maintained by controlling access so that each access to one of the files at the remote file server is performed, if at all, on a respective portion of that file as most recently updated at the remote file server node.

A multi-user file storage service and system enable each user of a pre-subscribed user group to operate an arbitrary client node at an arbitrary geographic location, to communicate with a remote file server node via a wide area network and to access the files of the file group via the respective client node in communication with the remote file server node via the wide area network. More than one user of the pre-subscribed user group is permitted to access the file group at the remote file server node simultaneously. Illustratively, the integrity of the files at the remote file server node are maintained by controlling each access to each file at the remote file server node so that each access to files at the remote file server is performed, if at all, on a respective portion of each file as most recently updated at the remote file server node. Thus, all native operating system application programming interfaces operate as if all multi-user applications accessing the files function as if the remote server and client nodes were on the same local area network. Illustratively, an interface is provided for adapting file access one of the client nodes. The interface designates at the client node each accessible file of the group as stored on a virtual storage device. The interface enables access to the designated files in a fashion which is indistinguishable, by users of, and applications executing at, the client node, with access to one or more files stored on a physical storage device that is locally present at the client node. Illustratively, an encrypted key is transferred from the remote file server node to one of the client nodes via a secure channel. The key is encrypted using an encryption function not known locally at the remote file server node. The transferred key is decrypted at the client node. The key is used at the client node to decrypt information of the files downloaded from the remote file server node or to encrypt information of the files prior to uploading for storage at the remote file server node. Access control to a particular one of the files of the group can be delegated to an access control node.

A system for scheduling time intervals for a plurality of users comprises a database associated with one or more server means for storing a profile for each potential invitee of the system. Each invitee profile comprises user profiles that have information regarding available and unavailable times for that user and the electronic mail address for the user and resource profiles having information about the available times for a particular resource such as a room or equipment. A request generator connected over a network to the one or more server generates a request for allocation of a time interval for one or more of the plurality of invitees. The system then provides a busy time determination device that gathers the profiles for the plurality of invitees that were requested by the request generating means and that are available in the databases and determines whether those invitees are available during the time interval requested by the request generating means. For all available invitees, the electronic mail address in the profile is used to send each available requested invitee an invitation to attend at the requested time interval.

A file storage system for storing data of a file received from a client includes a back-end file server in which the data is stored. The system includes a cache appliance in communication with the file server, such that the appliance stores portions of the data or attributes of the file, and uses the stored data or attributes to process file system requests received from the client, and which reads and writes data and attributes to the back-end file server independently. A system for responding to a file system protocol request in regard to a back-end server includes a token server. The system includes a plurality of cache appliances in communication with the token server, each of which receives tokens from the token server to synchronize access to data and attributes caches of the cache appliances, and reading and writing data and attributes to the back-end servers when tokens are revoked, the cache appliance having persistent storage in which data are stored, and the token server having persistent storage in which tokens are stored. A storage system includes a plurality of backend servers. The system includes a token server which grants permission to read and write file attributes and data system, and includes a plurality of cache appliances in communication with at least one of the backend servers and the token server for processing an incoming NFS request to the one backend server. Each cache appliance comprises an NFS server which converts incoming NFS requests into cache manager operations; a token client module in communication with the token server having a cache of tokens obtained from the token server; a cache manager that caches data and attributes and uses tokens from the token client module to ensure that the cached data or attributes are the most recent data or attributes, and an NFS client which sends outgoing NFS requests to the back-end file server. Methods for storing data of a file received from a client.

Data access time in content delivery networks is improved by storing files in cache servers as file bundles. A cache server determines that multiple files are requested by the same client based on information available in the request including the IP address of the client, a URL of a webpage referring to the file, and / or a cookie stored at a client. The cache server stores multiple files requested by the same client on the hard drive as a file bundle with meta data associating the files with one another, such that they can be accessed together. A future request from the client for a file in a file bundle results in multiple files from the file bundle being loaded in the memory. If the client requests another file from the file bundle, the file is accessed directly from the memory instead of the hard drive, resulting in improved performance.

A method and system for shipping items. A server is configured to send out requests for quotes to a number of regional shipping companies using a network. The server receives responses from the network and selects a route based on the responses. The route may include shipping the item to one or more intermediate destinations before the item arrives at the final destination. The server may create a data file reflecting the selected route. The items are packed in one or more containers, wherein each container has a memory device. At least part of the data file is then stored into the memory device. The memory device may be accessed as needed during shipping to determine where the item is going and when the item needs to arrive. Additional information may also be stored in the memory device, and the device may be updated at intermediate destinations. Each container may take a different routing, and the server may actively search for better routings as the item proceeds along the selected route. The containers may be configured to be placed within carriers that hold multiple containers, and the carriers may also be configured with memory devices.
