The distributed data processing system further includes a results server which tabulates the content of completed ballots in a manner which maintains the identity of the voters associated with the particular ballots confidential. The distributed data processing system may further include a journal server which records completed ballots, in a manner which facilitates the challenge of ineligible votes and the correction of erroneous votes.

A method and apparatus for adaptively targeting advertisements to a specific client computer from a server within a distributed data processing system is provided. As a user of the client browses the World Wide Web, the material that is downloaded to the client constitutes a datastream. At some location during the routing of the datastream, either on the server or at the client, the datastream is scanned to generate a list of keywords that are present within the datastream. The datastream may be analyzed in real-time or cached and analyzed on a delayed basis. The generated list of keywords represents a summary of the content that appears to be the focus of interest of the user. The keywords are compared against a database of advertisements, and the server selects an advertisement that matches the user's area of interest in comparison to the analysis of the user's browsing history. The selected advertisement is then inserted into the datastream to be routed to the client. In consideration for viewing targeted advertisements and to entice a Web viewer to allow the monitoring of a datastream so that targeted advertisements may be placed into the datastream, a Web viewer may receive online connection service for free, for a reduced cost, at a premium level of service, or for other some other value, such as frequent viewer credits that may be exchanged for goods and services.

Syndrome values are employed as a mechanism for synchronization and consistency in a distributed data processing environment. Syndromes are computed for local resources on individual peer nodes and an aggregate syndrome is computed from the individual syndromes. This renders it easy to determine not only that a change has occurred but it also makes it easy to determine which node needs to be updated and thus avoids the needless transmission of updated contents.

A method, computer program product, and distributed data processing system for memory management. Memory regions are registered and have access rights and Protection domains associated with them in response to receiving a request for a memory operation including a virtual address, which is used to address into a data structure. A second data structure is then used to translate the virtual address into physical addresses for the operation. A third data structure is used to allow an incoming request responsive to a remote operation being initiated.

A method, system, apparatus, and computer program product are presented for management of resource leases within a distributed data processing system. A resource manager receives a lease request from a requester for a resource in which the lease request has a requested lease period. In response to receiving the lease request, the resource manager secures leases along a logical circuit of resources through the distributed data processing system. The resource manager requests leases from other resource managers along the data path that comprises the logical circuit because use of the requested resource requires use of other resources. After securing leases on a logical circuit of resources, the resource manager returns a lease grant for the resource to the requester. If the system detects oversubscribed conditions and/or error conditions, the system can adjust the pending leases in an appropriate manner, such as terminating a lease, adjusting the lease period of a lease, and the like.

A method, system, apparatus, and computer program product is presented for management of a distributed data processing system. The network management framework is able to monitor multiple sources of network packets on various subnets within the distributed data processing system; distributed packet snoopers are deployed from a packet usage manager to monitor the multiple sources of network packets. The system administrator can request packet filtering based upon selected active users or active applications. A bandwidth history database is compiled from bandwidth usage data associated with multiple entities within the data processing system, including users, applications, and/or endpoints within the data processing system. In response to a requested action within the data processing system, bandwidth usage for the requested action can be predicted with reference to the bandwidth history database. The actual and predicted bandwidth usage of requested actions can be displayed to the system administrator in real time.

A method, system, and computer program product is presented for providing access to a set of resources in a distributed data processing system. A reverse proxy server receives a resource request from a client and determines whether or not it is managing a session identifier that was previously associated with the client by the reverse proxy server; if so, it retrieves the session identifier, otherwise it obtains a session identifier and associates the session identifier with the client using information that is managed by the reverse proxy server. The reverse proxy server then modifies the resource request to include the session identifier and forwards the modified resource request to an application server.

A method for continually controlling the collective behavior of a set of computing devices in a distributed data processing system. A gateway node disseminates a specification request comprising a set of parameters to a set of computing devices. The gateway node may be unaware of the number and identity of individual computing devices. Each computing node receiving the request determines whether its attributes satisfy the predicates expressed in the specification request. If so, the node processes the parameters in the specification request and modifies its own behavior based on the values in the parameters of the specification request. Subsequently, the gateway node may also observe the quality of information (QoI) values communicated from the set of computing devices. The gateway node iteratively modifies the parameters disseminated in subsequent specification requests based on a divergence between a computed quality of information value and a desired quality of information value.

As a solution to the problem of distributed knowledge of data object definitions, data object definitions are removed from the source code. A Meta Data Service is created and made available on a network which knows the definitions of all of the objects that are used by applications that are designed to use the Meta Data Service. When an object is created, the Meta Data Service creates and stores a meta definition for the object. Data objects are passed over a network in a “soft” format. Applications within a distributed data processing system are designed in such a manner such that, at any stage of object processing, an application does not assume to understand the definition or structure of an object, nor is an application hard-coded with the object definitions. At each stage, an application queries the Meta Data Service for the meta definition of the object before proceeding with the processing of an object. The application then receives a meta definition for the data object that allows the application to perform properly tailored processing for the data object.

A method is presented for processing transactions in a federated computational environment. Resource requests are received at a first federated entity from a second federated entity. The first federated entity responds to federation protocol operations for the second federated entity in accordance with a trust relationship between the first and second federated entity. The services of the first federated entity are provided by a set of data processing systems within a distributed data processing system, and each data processing system in the set of data processing systems is able to act as an identity provider. A first data processing system in the set of data processing systems establishes itself to act as an identity provider for the set of data processing systems with respect to the second federated entity and then is employed to perform federated protocol operations as an identity provider for requests from the second federated entity.

A method for updating operational parameters of a monitoring agent on a client in a distributed data processing system is presented. The monitoring agent filters the outgoing network data traffic from the client to a server and determines whether an outgoing transaction is addressed such that an application on the server receives the outgoing transaction as a request to change the operational parameters of the monitoring agent. The outgoing transaction is parsed for a destination address and matched with a destination address stored as an operational parameter of the monitoring agent on the client. The destination address may be a Uniform Resource Locator (URL) embedded within a Hypertext Transport Protocol (HTTP) request. In response to a positive determination, the monitoring agent then sends a request to the server to send to the monitoring agent an update of the operational parameters of the monitoring agent.

To suppress a server processing load and a network load in a sensor network which accommodates a great number of mobile sensor nodes. Among a plurality of distributed data processing servers (DDS) for managing data of sensor nodes, a distributed data processing server (DDS) that is a home server to hold data of a mobile sensor node is set for each sensor node by a directory server (DRS). At each distributed data processing server (DDS), upon reception of the data from the sensor node, identification process is executed as to whether the data is sensor data to be managed by itself or another distributed data processing server. If a result of the identification is the sensor data to be managed by another distributed data processing server, the data is transferred to the distributed data processing server (DDS-1), which corresponds to the home server of the sensor data, based on setting of the directory server (DRS).
