Multiple applications request data from multiple storage units over a computer network. The data is divided into segments and each segment is distributed randomly on one of several storage units, independent of the storage units on which other segments of the media data are stored. At least one additional copy of each segment also is distributed randomly over the storage units, such that each segment is stored on at least two storage units. This random distribution of multiple copies of segments of data improves both scalability and reliability. When an application requests a selected segment of data, the request is processed by the storage unit with the shortest queue of requests. Random fluctuations in the load applied by multiple applications on multiple storage units are balanced nearly equally over all of the storage units. This combination of techniques results in a system which can transfer multiple, independent high-bandwidth streams of data in a scalable manner in both directions between multiple applications and multiple storage units.

A device for use as a portal in percutaneous minimally invasive surgery performed within a patient's body cavity includes a first elongated hollow tube having a length adjusted with a self-contained mechanism. The first elongated tube includes an inner hollow tube and an outer hollow tube and the inner tube is adapted to slide within the outer tube thereby providing the self-contained length adjusting mechanism. This length-adjustment feature is advantageous for percutaneous access surgery in any body cavity. Two or more elongated tubes with adjustable lengths can be placed into two or more adjacent body cavities, respectively. Paths are opened within the tissue areas between the two or more body cavities, and are used to transfer devices and tools between the adjacent body cavities. This system of two or more elongated tubes with adjustable lengths is particularly advantageous in percutaneous minimally invasive spinal surgeries, and provides the benefits of minimizing long incisions, recovery time and post-operative complications.

The disclosed embodiments disclose techniques for managing a global namespace for a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in a cloud storage system; the cloud controllers ensure data consistency for the stored data, and each cloud controller caches portions of the distributed filesystem. Furthermore, a global namespace for the distributed filesystem is also split across these cloud controllers, with each cloud controller “owning” (e.g., managing write accesses for) a distinct portion of the global namespace and maintaining a set of namespace mappings that indicate which portion of the namespace is assigned to each cloud controller. During operation, an initial cloud controller receives a request from a client system to access a target file in the distributed system. This initial cloud controller uses the namespace mappings for the global namespace to determine a preferred cloud controller that will handle the request.

An audio fingerprint is extracted from an audio sample, where the fingerprint contains information that is characteristic of the content in the sample. The fingerprint may be generated by computing an energy spectrum for the audio sample, resampling the energy spectrum logarithmically in the time dimension, transforming the resampled energy spectrum to produce a series of feature vectors, and computing the fingerprint using differential coding of the feature vectors. The generated fingerprint can be compared to a set of reference fingerprints in a database to identify the original audio content.

A platform-independent process for data retrieval from ontology-oriented data systems over computer networks through a flexible system and method of query paraphrasing. The present invention uses a “common ontology” that is not tied to any particular data system. Thus, each client computer issues queries to a target data system in the common ontology. Of course, the target data system will not be able to directly process the query (as it is not in its local ontology). Instead, the query is first paraphrased back from the common ontology into local ontology by taking the semantic query, passing it through a query paraphraser, and then sending the paraphrased query to the data system. Once it is paraphrased successfully, the target data system can process it and produce a result using local ontology. The result may then be sent from the data system to an answer paraphraser for paraphrasing, and the paraphrased answer may be returned to its original query issuer and on to the client.

The charge is preferably determined according to one of a plurality of rules, as applied by a rules engine of the billing system. These rules are part of a charging policy, which may optionally be determined by the content provider.

A method, system and apparatus for routing data through a network based on the content or semantics of the data. Semantic routing engines route the data through the network based upon information maintained in routing tables.

A method for performing end-to-end “tree-based ordered multicasting” (TOM) which ensures collective integrity and consistency of distributed operations, and which is applicable to distributed multiparty collaboration and other multipoint applications. The TOM protocol performs cascaded total ordering of messages among on-tree hosts en route from senders to receivers, and does not require the building of a separate propagation graph to compute ordering information. TOM elects sequencer nodes dynamically based on address extensions of the multicast tree. Message ordering is performed by multicasting a message from each source node to receivers, unicasting a control message from a source node across a primary node to an ordering node for the designated multicast group or transmission in the tree, determining a binding sequence number for the message and a multicast to the receiver group, and delivering messages at end hosts according to the agreed-upon sequence numbers.
