Abstract: A method of limiting reuse of domain name information is disclosed. In accordance with the method, domain name information is received at a first domain name sewer. The domain name information includes a time limit and a request limit associated with subsequent distribution of the domain name information to at least one requestor. The received domain name information is validated from a second domain name server based on earliest expiration of the time limit and the request limit.

Abstract: A service model, integrated system, and method for enabling a service provider to deliver an integrated web hosting and content distribution service offering, which affords assured operational performance service levels, regardless of whether the customer's web site is served by the service provider's hosting center, the service provider's content distribution network (CDN), by a third party web host, or by a third party CDN. A monitoring system of the primary service provider receives detailed capacity and health statistics from any CDN under the operational control of the primary service provider, receives aggregate capacity and health statistics from other CDNs not under the operational control of the primary service provider. A redirection system then decides to which web host, content distribution network, or combination thereof, user requests for content are directed in order that operational performance service levels are maintained.

Abstract: Methods, systems, and products generate web pages using elidable links to additional content. When a link is selected in a web page, elision is used to automatically remove a URL and its associated content from the web page, thus reducing previously visited material. When a user selects an elision-enabled link, the link is not displayed during subsequent displaying of the same web page.

Abstract: A method and system for providing click-once links is disclosed. Elision is used to automatically remove a URL and associated content from a web page as hyperlinks are selected, reducing previously visited material and providing visual feedback to a user. When a user selects an elision-enabled hyperlink, the hyperlink and its associated content are not displayed during subsequent displaying of the same web page. Web pages may be generated on the origin server and a browser client updates the content automatically. Click-once links may be flagged in an enclosing HTML source page through a combination of an indirection through a JavaScript function in an anchor and an additional HTML tag. Cookies may be used to record information about which links have been followed and to share such information with the origin server for use in subsequent page generation, or the browser may be adapted to perform elision without using cookies.

Abstract: A system and method for protecting streams in a mixed infrastructure includes determining processing elements that are to access a data stream in a stream processing environment and determining a security level for each processing element. Keys are generated per stream per processing element in accordance with the security level. The keys are associated with processing elements in an access control list in a location accessible by producing and consuming processing elements. The stream is decrypted for processing using keys released upon authenticating processing elements in accordance with the access control list. At security boundaries, the stream is re-encrypted in accordance with a next processing element.

Abstract: A system and method for securely processing sensitive streams in a mixed infrastructure includes analyzing a stream to determine data sensitivity. A likelihood that processing elements employed to process the stream would result in a risk to sensitive information is determined. At least a portion of the data stream having sensitive information is transferred to a secure processing environment to ensure security of the data stream during processing.

Abstract: A method of limiting reuse of domain name information includes the steps of requesting the information by a local domain name server from an authoritative domain name server, and providing this information to a requestor, such as a client or server. The domain name information includes an allowable usage limit that represents a maximum number of times that the information can be provided to the requestor before revalidating the information. A system for limiting reuse of domain name information includes an authoritative domain name server, a local domain name server, and a requestor. The authoritative server provides the information, which includes the allowable usage limit, in response to a request by the local server. The request from the local server may include the number of times that the local server provided the information to one or more requestors as an observed usage.

Abstract: A cooperative data stream processing system is provided that utilizes a plurality of independent, autonomous and possibly heterogeneous sites in a cooperative arrangement to process user-defined job requests over dynamic, continuous streams of data. A method is provided to organize the distributed sites into a plurality of virtual organizations that can be further combined and virtualized into virtualized virtual organizations. These virtualized virtual organizations can also include additional distributed sites and existing virtualized virtual organizations and all members of a given virtualized virtual organization can share data and processing resources in order to process jobs on either a task-based or goal-based allocation mechanism. The virtualized virtual organization is created dynamically using ad-hoc collaborations among the members and is arranged in either a federated or cooperative architecture. Collaborations between members is either tightly-coupled or loosely coupled.

Abstract: A cooperative data stream processing system is provided that utilizes a plurality of independent, autonomous and possibly heterogeneous sites in a cooperative arrangement to process user-defined job requests over dynamic, continuous streams of data. A mechanism is provided for orchestrating the execution of distributed jobs across the plurality of distributed sites. A distributed plan is created that identifies the processing elements that constitute a job that is derived form user-defined inquiries. Within the distributed plan, these processing elements are arranged into subjobs that are mapped to various sites within the system for execution. Therefore, the jobs are then executed across the plurality of distributed sites in accordance with the distributed plan. The distributed plan also includes requirements for monitoring of execution sites and providing for the back-up of the execution sites in the event of a failure on one of those sites.

Abstract: A failure recovery framework to be used in cooperative data stream processing is provided that can be used in a large-scale stream data analysis environment. Failure recovery supports a plurality of independent distributed sites, each having its own local administration and goals. The distributed sites cooperate in an inter-site back-up mechanism to provide for system recovery from a variety of failures within the system. Failure recovery is both automatic and timely through cooperation among sites. Back-up sites associated with a given primary site are identified. These sites are used to identify failures within the primary site including failures of applications running on the nodes of the primary site. The failed applications are reinstated on one or more nodes within the back-up sites using job management instances local to the back-up sites in combination with previously stored state information and data values for the failed applications.

Abstract: A cooperative data stream processing system is provided that utilizes a plurality of independent, autonomous and potentially heterogeneous sites in a cooperative arrangement to process user-defined inquiries over dynamic, continuous streams of data. The system derives jobs from the inquiries and these jobs are executed on the various distributed sites by executing applications containing processing elements on these sites. Therefore, components of a given job can be executed simultaneously and in parallel on a plurality of sites within in the system. The sites associated with a given job execution have the need to share data, both primal and derived. A tunnel mechanism is provided that establishes tunnels between pairs of sites within the system. Each tunnel includes either a sink processing element on an originating site and a source processing element on a destination site or a gateway processing element on each site and a network connection between the sink and source processing elements.

Abstract: A cooperative data stream processing system is provided that utilizes a plurality of independent, autonomous and possibly heterogeneous sites in a cooperative arrangement to process user-defined job requests over dynamic, continuous streams of data. The sites negotiate peering relationships to share data and processing resources to handle the submitted job requests. These peering relationships can be cooperative or federated and can be expressed using common interest policies. Each site within the system runs an instance of a system architecture for processing job requests and is therefore a self-contained, fully functional instance of the cooperative data stream processing system.

Abstract: A method (and system) of storing data in a value-based storage system, includes optimizing a value of data stored in the value-based storage system.

Abstract: A method and apparatus for scalable inquiries in a network of communicating peers are provided. The method and apparatus of the present invention make use of communal filters and randomization to determine which client devices will output a message that is to be broadcast to a community of client devices. Each message is assigned a probability value that is determined based on various criteria or may be determined randomly. The message is then transmitted to the client devices who apply their own respective display criteria to the message parameters to determine if the message is one that is of interest to the user of the client device. If the message is not of interest to the user of the client device, the message is discarded. If the message is of interest to the user, logic is applied to the parameters of the message to determine whether the message should be displayed to the user or not.
