摘要： 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. In additions to inter-site mechanisms, each one of the plurality of sites employs an intra-site back-up mechanism to handle failure recoveries within the site.

摘要： 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.

摘要： 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.

摘要： The invention provides for customized “what's new” lists for users of shared lists of tracked resources. Identifying information, such as cookies, and state information are used to personalize a shared “what's new” list, so that changes to a document which a particular user has viewed are indicated automatically based on the last time that user viewed the document. Thus, the user is notified of the set of changes that have taken place since the user last viewed a particular set of documents. For any particular document, only the changes which have occurred since the user last viewed that document are used to form the “what's new” list and to view the changes if the user so chooses. Additionally, a user can select multiple collections of documents into a single notification system and exclude particular documents or augment the collection to personalize the resources tracked for that user.
摘要翻译：本发明为追踪资源共享列表的用户提供定制的“新增功能”列表。使用识别信息（如Cookie和状态信息）来个性化共享的“新功能”列表，以便根据用户上次浏览文档的最后时间自动显示特定用户所查看的文档的更改。因此，用户被通知自用户上次查看特定文档集合以来发生的一组变化。对于任何特定文档，只有用户上次查看该文档后发生的更改被用于形成“新功能”列表，并在用户选择时查看更改。此外，用户可以将多个文档集合选择到单个通知系统中，并排除特定文档或扩充该集合以个性化为该用户跟踪的资源。

摘要： 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.

摘要： A method for storing data in a data storage system by partitioning the data into a plurality of data chunks and generating representative data for each of the plurality of chunks by applying a predetermined algorithm to each chunk of the plurality of chunks. Subsequently, the representative data is compared and sorted. Representative data for base data chunks and representative data for other data chunks that can be stored relative to the base data chunks are identified by evaluating the sorted set of representative data. Finally, each of the other data chunks identified as those that can be stored relative to a base data chunk are stored in the data storage system as the difference between the data chunk and a base data chunk.

摘要： 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.

摘要： A redundancy elimination mechanism is provided, which applies aspects of duplicate block elimination and delta encoding at the block level. The redundancy elimination mechanism divides file objects into content-defined blocks or “chunks.” Identical chunks are suppressed. The redundancy elimination mechanism also performs resemblance detection on remaining chunks to identify chunks with sufficient redundancy to benefit from delta encoding of individual chunks. Any remaining chunks that do not benefit from delta encoding are compressed. Resemblance detection is optimized by merging groups of fingerprints into super fingerprints. This merging can be constructed to ensure that if two objects have a single super fingerprint in common, they are extremely likely to be substantially similar.

摘要： 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.
