QoS is built into a peer network within existing Internet infrastructure itself lacking QoS, by enabling a network peer to continuously discern the network's ability to deliver to that peer a particular Content Object (distributed in groups of component Packages among neighboring VOD peers) within predetermined times. Content Objects are divided into groups of component Packages and distributed to Clusters of neighboring network peers, enhancing QoS upon subsequent retrieval. Tracking Files (lists of network peers storing Package groups) and Tracking Indexes (lists of network peers storing Tracking Files) are generated to facilitate “on demand” Content Objects retrieval. Dynamically monitoring network traffic (including VOD functionality, bandwidth and reliability) creates “distributed closed-loop feedback,” and in response, attributes of individual network peers (e.g., Trust Level and membership within a particular Cluster) are modified, and “content balancing” functions performed (e.g., redistribution of Package groups among network peers) enables maintaining high QoS.

An anonymous location wireless network service for use in a wireless network that tracks the location and identity of network users, such as networks complying with enhanced 911 standards. The service provides content providers with the location of network users without revealing their identities. The service includes a wireless network having a proxy server, a network communication link to a plurality of web sites, and a wireless communication link to a plurality of handheld devices. The proxy server blocks identity by reading the location and identity information of network devices, generating dummy identifications, relating the dummy identifications to the identity information, storing the relationships in a memory storage, and forwarding the location information and dummy identifications to the global computer network. Upon receiving return messages from the global computer network, the proxy server reads the dummy identifications, looks up the related identity information in the memory storage, and forwards the data to the appropriate network devices.

The present invention provides a method, system, and software for dynamically generating a customized menu page on a display of a client system coupled to a network, such as the Internet. The menu page includes a number of selectable icons, each associated with a particular Web site, service, Web guide channel, etc., that the user is likely to wish to access. The menu page is “customized” in the sense that each menu page is generated based on each user's network log history and preferences, as stored in a user preference database, so as to present only those information sources/services that he/she would want to access. The menu is “dynamically” generated in the sense that the user preference database is constantly updated so as to present a menu page that reflects the user's most recent preferences and history.

A memory system is presented where sectors are normally stored in logically contiguous groups. As repeated writes of the same small sector group can causes a massive garbage collection (data relocation), the pattern of host access is monitored by checking the sectors' update history and control data structures' update history. When repeated access patterns are detected and then expected again, the “hot” segments are separated into specially handled, non-standard zone in the memory. The non-standard zone has a sector management that is different from the logical groups and optimized for the repeated host accesses in order to reduce the frequency and amount of garbage collection operations.

A hierarchically-structured computer mass storage system and method. The mass storage system includes a mass storage memory drive, control logic on the mass storage memory drive that includes a controller and one or more devices for executing a hierarchical storage management technique, a volatile memory cache configured to be accessed by the control logic, and first and second non-volatile storage arrays on the mass storage memory drive and comprising, respectively, first and second non-volatile memory devices. The first and second non-volatile memory devices have properties including access times and write endurance, and at least one of the access time and the write endurance of the first non-volatile memory devices is faster or higher, respectively, than the second non-volatile memory devices. Desired data storage localities on the storage arrays are determined through access patterns and selectively utilizing the properties of the memory devices to match the data storage requirements.

With the proliferation of travel websites, users must separately search competing travel websites to find a travel service that satisfies their travel preferences. A travel agent is provided for automatically searching multiple travel websites for travel services satisfying search criteria that are based on a user's travel preferences. The travel agent implements a search strategy to automatically access, navigate, and parse one or more travel websites, enter search parameters, and extract data associated with relevant travel services. The travel agent can execute on a user's personal computer to harness the computational power of the personal computer and reduce the burden on centralized servers that search for travel services. Moreover, by storing a user's travel preferences on the same personal computer, the travel agent reduces access times to user data and protects it from insecurities associated with transmission over a network.

An image retrieval system has a network server, at least one client terminal and a data archive of a multiuser file management system, spatially separated from server and client, of a file server. A reduced data stream is now transmitted between server and client and includes a header for transmitting address and meta information with an additional data field that includes an access key to the bulk data stored in the external data archive. This reduces the data volume to be transmitted during image retrieval, and thus reduces the network utilization in the transmission of the data stream occurring between server and client. As a result of this, the time period required to transfer the modified data stream between server and client terminal is correspondingly short.

In embodiments of the present invention improved capabilities are described for reducing computer file access time associated with on-access scanning through predictive preemptive scanning, where the prediction may be enabled through the development and use of a file access performance cost mapping of a computing facility's file system. In a first step, file access information describing a pattern of each of a plurality of computer files that have been accessed in a computer file system may be collected. In a second step, the file access information may be processed to generate a file access performance cost statistic for each of the plurality of computer files, where the file access performance cost statistic may be a measure of the time aggregate effect on the computing facility's system performance associated with the access of the file. In a third step, the file access performance cost statistic may be maintained for each of the plurality of files accessed by the computing facility. In a fourth step, the file access performance cost mapping of the computing facility's file system relating to the plurality of computer file may be generated, where the file access performance cost mapping may provide an indication of which of the plurality of files in the file system produce the greatest time aggregate file access effect based on the computing facility's system performance. Finally, in a fifth step, files from the computer file system may be pre-scanned based on the file access performance cost mapping. In embodiments, pre-scanning may access at least one of the plurality of files for scanning prior to the file being called for a use, such as by an operating system, an application, a utility program, and the like. The step of pre-scanning may be performed during periods of low computing facility processing activity, and may result in a reduced need to scan the computer file when the computer file is accessed for use.

A storage system of the present invention saves power consumption of the storage system and enhances responsiveness by predicting a disk drive that is to be accessed next on the basis of an access request from a host system, and promptly feeding power to the predicted disk drive. A prediction unit predicts the disk drive which is to be accessed next by the host system, by comparing a recent access request from the host system against a past access pattern that is registered in an access pattern record table. A power control unit feeds power from a power unit to the disk drive predicted by the prediction unit.

An LRU array and method for tracking the accessing of lines of an associative cache. The most recently accessed lines of the cache are identified in the table, and cache lines can be blocked from being replaced. The LRU array contains a data array having a row of data representing each line of the associative cache, having a common address portion. A first set of data for the cache line identifies the relative age of the cache line for each way with respect to every other way. A second set of data identifies whether a line of one of the ways is not to be replaced. For cache line replacement, the cache controller will select the least recently accessed line using contents of the LRU array, considering the value of the first set of data, as well as the value of the second set of data indicating whether or not a way is locked. Updates to the LRU occur after each pre-fetch or fetch of a line or when it replaces another line in the cache memory.
