Abstract:
The information access monitor is located at the Internet gateway of a network. The information access monitor monitors information flows between the internal data communication network and Internet to identify information requests and responses. The Information Access Monitor generates relevance indexes for these requests and responses and compiles a “corporate consciousness” of all data relevant to the organization. The information access monitor computes user/group profiles to identify information needs and interests within the organization and can then automatically associate users/groups with information of relevance. The users can be advised of information via automated “copy to” lists or can be directed to information in response to the user seeking information. The information accessmonitor thereby automatically creates “virtual bibliographies” which reflect topics of interest to the users of the system. These virtual bibliographies are continuously created and updated as needed by the users.
Abstract:
The adaptive bandwidth throttling system implements a graceful diminution of services to the clients by delaying a first class of services provided by a network server in response to the effective bandwidth utilized by this network server exceeding a first threshold. If the demand for the bandwidth by this network server exceeds a second threshold, the bandwidth throttling system escalates the throttling response and blocks the first class of services from execution and can also concurrently delay execution of a second class of services. The implementation of the throttling process can be varied, to include additional levels of response or finer gradations of the response, to include subsets of a class of services. In addition, the threshold levels of bandwidth used to trigger the throttling response can be selected as desired by the system administrator. Typically, once the effective bandwidth utilization is approximately equal to the allocated bandwidth for the network server, the first level of the hierarchical bandwidth throttling is activated. The second level of the hierarchical bandwidth throttling is activated once the effective bandwidth utilization exceeds the allocated bandwidth for the network server by greater than a predetermined amount.
Abstract:
Loyalty offer techniques are described. In one or more implementations, data is received from a plurality of merchants via a network, the data describing transactions for goods or services initiated at physical locations of respective said merchants and including identifiers that uniquely identify mobile communication devices that were used to initiate the transactions. Information is updated that describes participation in one or more loyalty offers associated with the plurality of merchants using the identifiers that uniquely identify the mobile communication devices and the data that describes the transactions.
Abstract:
A method and a processing device may be provided for creating a shadow database, having a size being approximately a desired percentage of a size of a relational database. Referential integrity of tables of the relational database may be preserved in the created shadow database. A representation of a connected graph may be created, based on a schema description of the relational database, and may be used to find driving tables and related tables of the relational database. Portions of driving tables of the relational database may be copied to corresponding tables of the shadow database and rows of tables of the relational database, related to the copied portions of the driving tables, may be copied to corresponding tables of the shadow database in a number of iterations until the size of the shadow database is approximately the desired percentage of the size of the relational database.
Abstract:
The present invention relates to a system and methodology providing an automated and dynamically responsive infrastructure to support online subscription services. The system includes one or more components to coordinate and manage a plurality of services offered by multiple service providers. This can include automatically creating and managing billing accounts for customers subscribing to such services. At least one engine is provided to process multiple rules in response to subscription events that occur in connection with the services in order to facilitate service delivery. At least one rating processor is provided to process multiple rating rules in response to subscription events for currency and non-currency resources.

Abstract:
A session manager has a session timeout mechanism to selectively timeout client-server sessions. The session timeout mechanism has multiple timeout buckets to hold corresponding groups of sessions according to the sessions' timeout periods. Sessions located in different ones of the timeout buckets are set to timeout at different times. The session manager also has a session timeout clock that is incremented every predetermined time unit (e.g., every minute). The session timeout clock maintains a pointer to one of the timeout buckets and advances that pointer with each clock increment. The session timeout clock advances the pointer through all of the timeout buckets, one bucket at a time. The session timeout clock advances the pointer repeatedly through all the buckets. The cycle time for the session timeout clock to reference every timeout bucket is equal to the incremental time unit multiplied by the number of buckets. A new session (or one that recently received a request and is restarting its timeout period) is inserted into a timeout bucket that is one or more buckets ahead of the clock pointer, depending upon the session's timeout period. When the timeout clock references a particular bucket, the sessions in that bucket are analyzed for possible timeout. Sessions whose timeout period has run without receiving any new requests are timed out and removed from the bucket.
Abstract:
A bandwidth throttling system is implemented on a server network connected to a computer network system to serve one or more clients over a network. The network server supports a service that presents multiple virtual services that can be individually requested by the clients. The bandwidth throttling system controls bandwidth on a per virtual service basis. The bandwidth throttling system has a measuring subsystem to measure the amount of bandwidth being used by each virtual service supported by the network server. The bandwidth throttling system also has a control subsystem to selectively throttle requests for a particular virtual service independently of others based upon the bandwidth used by the particular virtual service. The bandwidth throttling system utilizes an adaptive, hierarchical throttling strategy that is applied to each virtual service independently. The bandwidth throttling system compares the bandwidth usage for the virtual service against the administrator-defined thresholds for that virtual service. If the presently used bandwidth exceeds a first threshold, a first set of throttling actions is applied. If the presently used bandwidth exceeds a second threshold greater than the first threshold, a different second set of throttling actions is applied. In this manner, the administrator is given maximum control at setting throttling policies for each individual virtual service independently of other virtual services.
