摘要： A system and method to support runtime model extension in an Object Relational Mapping (ORM) System. The system includes a relational data storage subsystem for storing and retrieving objects in form of relational data, a tuple storage subsystem for storing and retrieving objects in form of tuple, and a dispatcher/assembler for storing and retrieving original part and extended part of the object respectively into/from the relational data storage subsystem and the tuple storage subsystem. Thus, model extension can be carried out dynamically in the runtime of the ORM system without modifying schema and migrating data in the relational database.

摘要： A computer-implemented method, computer program product and computer readable storage medium directed to decentralized load distribution in an event-driven system. Included are receiving a data flow to be processed by a plurality of tasks at a plurality of nodes in the event-driven system having stateful and stateless event processing components, wherein the plurality of tasks are selected from the group consisting of hierarchical tasks (a task that is dependent on the output of another task), nonhierarchical tasks (a task that is not dependent on the output of another task) and mixtures thereof. Tasks are considered for migration to distribute the system load of processing tasks. The target node, to which the at least one target task is migrated, is chosen wherein the target node meets predetermined criteria in terms of load distribution quality. The computer-implemented method, computer program product and computer readable storage medium of the present invention may also include migrating tasks to target nodes to reduce cooling costs and selecting at least one node to go into quiescent mode.

摘要： A method and apparatus to dynamically maintain META-tag information specifying categorization and/or degree of compound documents, which are collections or hierarchy of collections of objects (possibly web pages), for efficient retrieval of leaf or intermediate objects with specific characteristics without the need to search any content of the collection. The specific characteristic and the contents of the collection can change constantly both qualitatively and quantitatively (including the insertion, deletion and update of objects). While dynamically maintaining the META-tag information, there are no inclusion restrictions on these compound documents, i.e., any collection can contain itself either directly or recursively; and all objects within a META-tagged compound document are not required to participate. The PICS protocol may be used to specify this META-tag information with both categorization and degree; to reflect the obsolescence, currency or freshness of an objects; to validate a given object using a digital signature; and to enable charging for the META-tag service. Aggregation methods are provided to enable maximization, minimization, and averaging; to limit the propagation of META-tags; and to handle the time-out of META-tag and information validity.

摘要： In a scheduling system, events and/or groups of events are checked at a scheduling time to insure that certain fixed conditions associated with the event(s) are satisfied. The events are also checked at one or more times, between scheduling time and a performance time (when the event(s) are to be performed), called "prepare to perform time(s)." At the prepare to perform time(s), certain dynamic conditions and/or data associated with the events are checked to determine whether the dynamic conditions are satisfied. If the dynamic conditions are satisfied, the event(s) are confirmed for performance. If one or more of the dynamic conditions are not satisfied, the event(s) are modified. Events can be modified by cancelling, altering or postponing. When an event(s) is modified, a notification can be sent out. Further, a modification of a event(s) can cause modifications to one or more subsequent events in the event group (propagation.) Templates are event groups with some omitted information that is provided by a user at scheduling time. Templates are used to facilitate the scheduling of common events and/or event groups.

摘要： A computer-implemented method, computer program product and computer readable storage medium directed to decentralized load placement in an event-driven system so as to minimize energy and cooling related costs.

Nodes are considered for quiescing whose current tasks can migrate to other nodes while meeting load distribution and energy efficiency parameters and the expected duration of the quiesce provides benefits commensurate with the costs of quiesce and later restart.

摘要： A method and system of collaboratively caching information to allow improved caching decisions by a lower level or sibling node. In a caching hierarchy, the client and/or servers may factor in the caching status at the higher level in deciding whether to cache an object and which objects are to be replaced. The PICS protocol may be used to pass the caching information of some or all the upper hierarchy down the hierarchy. Furthermore, the caching status information can also be used to direct the object request to the closest higher level proxy which has potentially cached the object, instead of blindly requesting it from the next immediate higher level proxy. A selection policy used to select objects for replacement in the cache may be prioritized not only on the size and the frequency of access of the object, but also on the access time required to get the object if it is not cached. The selection policy may also include a selection weight factor wherein each object is assigned a selection weight based on its replacement cost, the object size and how frequently it is modified. Non-uniform size objects may be classified in ranges of selection weights having geometrically increasing intervals. Multiple LRU stacks may be independently maintained wherein each stack contains objects in a certain range of selection weights. In order to choose candidates for replacement, only the least recently used objects in each group need be considered.

摘要： A method and system for manipulating or modifying identifiable objects in a standard broadcast or Internet-based multimedia stream according to a control specification and a content specification. Viewers and/or organizations can independently specify acceptable levels of content on multiple dimensions to satisfy the content specification while minimizing the filtering or blocking to the viewers. A “fuzz ball” control specification is provided for masking some portion of a video frame. Several fuzz ball specifications can be overlaid to address multidimensional content specifications or rating systems. The manipulation of the multimedia stream can take place at the client (set-top box or computer), intermediate node, the content server or a combination thereof. Proxy servers can modify content specifications for outgoing requests, enabling organizations to specify intranet-wide policies. Multicasting can be supported by using a single stream delivered to multiple clients, each modifying the video using a different specification. The specification to facilitate modification can be done at different granularity levels: the video, a group of frames, or individual frame level and can also be time-based. Various protocols can be used to provide the content and/or control specification, including the VBI of a standard broadcast, PICS, RTSP and MPEG protocols.

摘要： Method, system and computer program product for collaboratively processing a data object in a client-server hierarchy based on meta-information associated with the object. Processing results are indicated by the server that performed the processing as updates to the meta-information associated with the data object. The PICS protocol may be used to communicate the meta-information. Digital signing and authentication of the object and associated meta-information are also described. Further, servers can determine processing by considering various factors, e.g., their current load condition; if the object is to be multicast; if the object can be cached; and/or if the specified cost and time constraints can be met. The overall processing applied to data objects can be divided between servers based on object types, steps, functions, software packages or versions/releases. Other aspects of the invention are also described.
