An end-to-end monitoring mechanism whereby edge nodes are notified that a particular path flows through a local protection tunnel along the way. The notification mechanism utilizes OAM packets which include a link protection indication that are transmitted on the Ethernet service layer. The link protection indication may be represented by one or more flags to indicate that local protection is in place along the path. The mechanism enables fast local protection to be used with slower end-to-end protection by informing the latter when local protection is activated. In an implementation in which local-protection does not preserve the CIR of the protected traffic, the invention provides minimal interruption of Committed Information Rate (CIR) connections by minimizing the time traffic is diverted through local protection tunnels. Notification of the edge node that local protection is in use occurs very quickly, thus allowing the edge node to rapidly switch to a backup path.

A system for distributing incoming client requests across multiple servers in a networked client-server computer environment processes all requests as a set that occur within a given time interval and collects information on the attributes of the requests and the resource capability of the servers to dynamically allocate requests in a set to the appropriate servers upon completion of the time interval. Preferably, a request table collects at least two requests incoming within a predetermined time interval, a request examiner routine analyzes each collected request with respect to at least one attribute, a system status monitor collects resource capability information of each server in a resource table and an optimization and allocation process distributes collected requests in the request table across the multiple servers upon completion of said time interval based on an optimization of potential pairings of the requests in the request table with servers in the resource table.

A method for caching media content on a client includes organizing media subjects in a predefined media package structure, and downloading the structure to the client in order for a user to consume the subjects in the structure. The media structure is arranged to allow a user to request media subjects by navigating from a current subject to adjacent subjects in the structure, and these adjacent subjects are cached at the client in advance, before the user requests them. By downloading the adjacent media subjects, the user will get the impression that the entire media structure is cached, and will not experience any download delays.

A system for distributing incoming client requests across multiple servers in a networked client-server computer environment processes all requests as a set that occur within a given time interval and collects information on both the attributes of the requests and the resource capability of the servers to dynamically allocate the requests in a set to the appropriate servers upon the completion of the time interval. Preferably, the system includes a request table to collect at least two requests incoming within a predetermined time interval. A request examiner routine analyzes each collected request with respect to at least one attribute. A system status monitor collects resource capability information of each server in a resource table. An optimization and allocation process distributes collected requests in the request table across the multiple servers upon completion of said time interval based on an optimization of potential pairings of the requests in the request table with the servers in the resource table. The optimization and allocation process preferably analyzes metrics maintained in the request table and resource table as part of a relational database to allocate requests to servers based on a minimization of the metric distance between pairings of requests and servers. Preferably, the request table is part of a dynamic, relational database and a process of statistical inference for ascertaining expected demand patterns involving said the attributes adds predictive information about client requests as part of the request examiner routine.

An electronic gaming system has a plurality of tables each having a plurality of electronic player interaction areas (EPIA's) spaced preferably about a table periphery so that a gaming player locates oneself in front of a respective EPIA to play a game. A controller of the system assigns any one of preferably a variety of games to any one table. The player is then free to choose what game he / she desires to play by picking a particular table. When playing of a game is being conducted by the controller at a particular table, the table is considered to be active. When a table is without players and thus a game is not being played, the table is considered to be inactive. The gaming system has a host console that communicates with each EPIA via the controller for managerial control of the plurality of tables. A host interface of the host console enables input by a host to move a game and the respective players from an active table to an inactive table.

A method and apparatus for enabling a common data set to be utilized by multiple data processes. During a first operating mode, first and second data stores in a data storage facility with a common buffer attach to a first data process and act as mirrors. Data to be written transfers to the common buffer and then to the data stores. A second command produces a split whereby the first data store remains attached to the first data process and the second data store is available to the second data process. After the second command is executed, any data in the common buffer is transferred to the corresponding data stores in parallel with and transparently to the actions between the first and second data processes and the first and second data stores, respectively.

Construction and advantages of improved wavy composite structures made from wavy composite, unidirectional composites, and damping materials is revealed. By combining wavy composite laminae in various waveforms, offsets, angular orientations and material combinations, it is possible to provide axial, torsion, or shear properties equivalent to unidirectional materials but without the limitations related to fiber discontinuity, labor costs for fabrication, and weakness at seams where laminates overlap. By combining wavy composite layers with unidirectional crossplies, or by using woven mats with various fill fiber levels where the warp fibers are sinuously arranged, improved strength and damping is possible. Several examples of both wavy crossply laminates and unidirectional crossply laminates are analyzed and compared.

A method and mechanism for generating a snapshot in a computing system. On initiating a snapshot of a first storage, the content of a portion of the first storage that includes at least one block is copying to snapshot storage and a copied indication for each copied block is recording in a copy map. Responsive to any write request to a block for which no copied indication has been recorded in the copy map, the content of the block is copied to the snapshot storage, prior to writing to that block. The content of other blocks for which no copied indication has been recorded in the copy map is successively copied to the snapshot storage. A copied indication for each copied block is recorded in the copy map. The successive copying can be performed as a background task.

The present invention relates to a method for optimizing the use of client capacity when providing information contents to a user. First, two modes of navigation of the client are defined: a first, continuous navigation mode, characterized by restricted movement among the contents, and a second, discontinuous mode, characterized by unrestricted movement among the contents. Then it is determined which mode of navigation the user is currently using, and the utilization of client capacity is adapted based on the currently used mode of navigation. In the first mode of navigation, user action can be more easily anticipated, and the client capacity can be used for improving the ongoing media consumption. In the second mode of navigation, user action is more difficult to predict, and client capacity may be needed for handling unexpected actions.
