A method and system for controlled provisioning of a desired set of service logic for a subscriber of group of subscribers. In response to a designated stimulus, such as a time-event, a location-event or a threshold-event, a network entity modifies the subscriber profile maintained by a serving system, so as to include in the profile one or more desired parameters. One such modification may be the inclusion in the profile of a trigger that directs the serving system to query a designated network entity for call handling instructions. The designated network entity may then provide a special set of services for the subscriber or group. Further, a mechanism is provided to help ensure that once such a service overlay is imposed, it remains imposed if desired.

A denial-of-service network attack detection system is deployable in single-homed and multi-homed stub networks. The detection system maintains state information of flows entering and leaving the stub domain to determine if exiting traffic exceeds traffic entering the system. Monitors perform simple processing tasks on sampled packets at individual routers in the network at line speed and perform more intensive processing at the routers periodically. The monitors at the routers form an overlay network and communicate pertinent traffic state information between nodes. The state information is collected and analyzed to determine the presence of an attack.

The system displays the cause of the specific alarm. The database includes alarms and events of network devices, network systems, and network applications. The specific alarm consists of a notification of an occurrence of the plurality of events.

The present invention is directed towards methods and systems for performing maintenance on computers included in a group of load balanced computer. A maintenance agent identifies a computers in the group as requiring maintenance, and a second computer as having up-to-date maintenance and a load level below a limit. The load balancer may assign a request to the second computer responsive to the identification. Responsive to a determination that spare capacity from the plurality of computers available to receive requests is above the threshold and that the first computer is idle, the maintenance agent may remove, for maintenance, the first computer from the plurality of computers available to receive requests. The maintenance agent may identify the first computer as having up-to-date maintenance responsive to the maintenance.

Mechanisms and techniques operating in a content distribution network in a peering relationship with a second content distribution network. The system maintains a first client list identifying a first set of client devices associated with a first content distribution network. The system also obtains a second client list identifying a second set of client devices associated with a second content distribution network. The system applies a client list filtering technique to the first client list and the second client list to produce a preferred client list associated with the second content distribution network. The preferred client list potentially identifies at least one preferred client device for which the second content distribution network preferably processes client requests. The system then operates a content routing technique to direct a client request associated with a client device to a content distribution network having a preferred client list that identifies the client device associated with the client request as a preferred client device.

A non-volatile solid-state storage subsystem, such as a non-volatile memory device, maintains usage statistics reflective of the wear state, and thus the remaining useful life, of the subsystem's memory array. A host system reads the usage statistics information, or data derived therefrom, from the subsystem to evaluate the subsystem's remaining life expectancy. The host system may use this information for various purposes, such as to (a) display or report information regarding the remaining life of the subsystem; (b) adjust the frequency with which data is written to the subsystem; and/or (c) select the type(s) of data written to the subsystem.

Embodiments of the present invention are directed to methods for maintaining data consistency of data blocks during migration or reconfiguration of a current configuration within a distributed data-storage system to a new configuration. In one embodiment of the present invention, the current configuration is first determined to be reconfigured. The new configuration is then initialized, and data blocks are copied from the current configuration to the new configuration. Then, the configuration states maintained by component data-storage systems that store data blocks of the current and new configurations are synchronized. Finally, the current configuration is deallocated. In a second embodiment of the present invention, a current configuration is determined to be reconfigured, and, while carrying out continuing READ and WRITE operations directed to data blocks of the current configuration in a data-consistent manner, the new configuration is initialized, data blocks are copied from the current configuration to the new configuration, and the timestamp and data states for the data blocks of the current and new configurations are synchronized.

A system and method reclaims unused storage space from a data container, such as a logical unit number (LUN) of a storage system. In particular, a novel technique is provided that allows a storage system to reclaim storage space not used by a client file system for which the storage system maintains storage, without requiring assistance from the client file system to determine storage usage. In other words, storage system may independently reclaim storage space not used by the client file system, without that file system's intervention.

Under an embodiment of the invention, a web site system maintains a real estate web page. The web page has an aerial image map of a geographic region that can be navigated by a user. The web site system facilitates online collaboration for real estate transactions. When the user registers, the system creates a user account for real estate information. Real estate agents and/or other real estate service providers selected by the user are granted shared access to the user's account by the web site system.

When a primary data storage subsystem receives updates for local storage and mirroring at a counterpart secondary storage subsystem, the primary subsystem institutes device-specific, fairness-driven update blocking to avoid overrunning the primary subsystem's update buffer with updates destined for any one device. Broadly, the primary subsystem first receives update requests, then logs the updates in an update buffer, then stores the logged updates in primary storage, and finally copies the updates to the secondary storage subsystem. Each update request includes update data and also identifies a targeted logical device, physical device, or other subpart of primary storage. The primary subsystem maintains a counter or other update activity indicator that represents update activity for each storage subpart, such as the number of updates stored in the buffer. For each update request, the primary subsystem determines whether target subpart's update activity exceeds a prescribed level. If not, the update data is stored in primary storage. Otherwise, if the update activity is excessive, the primary subsystem rejects the update. Optionally, the primary subsystem may selectively override certain rejections to prevent completely blocking updates for that subpart.

A complaint resolution system, also referred to as a disputes system, enables registered consumers to file a complaint against a merchant. During complaint preparation, the disputes system advises the consumer of relevant cases and other information, allows the consumer to vent their emotions, and prepares a well-formed complaint on behalf of the consumer. After the consumer approves filing of the complaint, the complaint is compared with the merchant's stored business rules. If the merchant's solution for the problem and the consumer's desired solution match, then the disputes system automatically forms an agreement. The disputes system monitors compliance with the agreement by the merchant and consumer. If the merchant has specified a business rule for the problem, but the merchant's solution for the problem and the consumer's desired solution differ, then the disputes system initiates automated mediation, automatically preparing an Answer comprising the solution from the merchant's business rule as the merchant's starting negotiating position. If the merchant has not specified a business rule for the consumer's problem, then the disputes system initiates automated mediation, asking the merchant for his or her Answer to the consumer's complaint. During processing of the consumer's complaint, the disputes system maintains and updates a detailed case record. At the conclusion of the case, the disputes system automatically prepares an anonymized case summary, and adds the anonymized case summary to a database of anonymized case summaries.

An environment setup apparatus and method for a home gateway system for a home gateway that provides triple play service.

An embodiment of the invention is a method of integrating public and private calendars on a user-specific basis, such that a user is able to view multiple shared calendars created by different users. A system maintains event data relating to a future event, and receives a request to add that event to one of the user's calendars. The system creates a link between that event and the calendar, configuring the link so that updates to the event are automatically reflected on the calendar. It further enables the user to modify attributes associated with the event.

A computer system configured for policy-based management of software updates is disclosed. The system maintains group-policy objects, with which groups of computers are associated. The system obtains identities of software updates from a source of software updates. The system also obtains filter criteria for each update, for determining whether the update should be applied to a particular computer or not. The system assigns newly available updates to respective selected group-policy objects and adds the obtained filter criteria to each such group-policy object. The system performs necessary installations of updates by, for each group-policy object, determining whether, for each combination of a computer belonging to a group associated with that policy object and an update assigned to that policy object, the computer satisfies the filter criteria for the update, and if so, applying the update to that computer, but if not, refraining from applying the update.

A system and a method for predicting the musical taste and/or preferences of the user and its integration into services provided by a wireless network provider. Although the present application is directed toward implementations with wireless providers, the present invention can also be implemented on a regular, i.e., wireline network. The core of the present invention is a system capable of predicting whether a given user, i.e., customer, likes or does not like a specific song from a pre-analyzed catalog. Once such a prediction has been performed, those items that are predicted to be liked best by the user may be forwarded to the mobile device of the user on the cellular (or other wireless) network. The system maintains a database containing propriety information about the songs in the catalog and, most important, a description (profile) of the musical taste of each of its customers, identified by their cellular telephone number.

One embodiment of the present invention provides a system that identifies network switches along a path. During operation, the system receives an address of a source node and an address of a destination node. The system maintains a set of topology information for a network. The system further simulates a data packet originated at the source node and destined for the destination node. During the simulation, the system determines whether a current-hop node performs layer-3, layer-2, or sub-layer-2 switching. The system sends a query to the current-hop node over a separate control channel to determine the status of the current-hop node and discover a next-hop node. The system then receives a reply. The system determines the next-hop node based on the reply and sets the next-hop node as the current-hop node.

An access server computing system scrapes a set of records maintained by a target computing system in a database which is only made accessible over the Internet with a limited protocol query and an access challenge. The access server accesses the target computing system through an Internet browser interface based on emulating a user query made through the limited protocol, including by automatically passing locator identifier fields to retrieve a corresponding set of record which are stored in the first database.

Software architecture for developing distributed fault-tolerant systems independent of the underlying hardware architecture and operating system. Systems built using architecture components are scalable and allow a set of computer applications to operate in fault-tolerant/high-availability mode, distributed processing mode, or many possible combinations of distributed and fault-tolerant modes in the same system without any modification to the architecture components. The software architecture defines system components that are modular and address problems in present systems. The architecture uses a System Controller, which controls system activation, initial load distribution, fault recovery, load redistribution, and system topology, and implements system maintenance procedures. An Application Distributed Fault-Tolerant/High-Availability Support Module (ADSM) enables an applications( ) to operate in various distributed fault-tolerant modes. The System Controller uses ADSM's well-defined API to control the state of the application in these modes. The Router architecture component provides transparent communication between applications during fault recovery and topology changes. An Application Load Distribution Module (ALDM) component distributes incoming external events towards the distributed application. The architecture allows for a Load Manager, which monitors load on various copies of the application and maximizes the hardware usage by providing dynamic load balancing. The architecture also allows for a Fault Manager, which performs fault detection, fault location, and fault isolation, and uses the System Controller's API to initiate fault recovery. These architecture components can be used to achieve a variety of distributed processing high-availability system configurations, which results in a reduction of cost and development time.

A system comprises a first storage system, a second storage system, a plurality of switches, and a server connected with the first storage system via a first group of switches and connected with the second storage system via a second group of switches. The first group and the second group have at least one switch which is not included in both the first and second groups. The first storage system receives I/O commands targeted to first logical units from the server via the first group of switches. The first storage system maintains first information regarding the ports of both the first and second storage systems. The first information is used to generate multipath communication between the server and the first storage system, including at least one path which passes through the second storage system and at least one other path which does not pass through the second storage system.
