Abstract: Fast retrieval and progressive retransmission of content, including the steps of obtaining erasure-coded fragments by an assembling server from fractional-storage CDN servers; reconstructing a streaming content file from the obtained fragments; and streaming the reconstructed content or a transcoded version of the content by the assembling server to a client device. Wherein most of the fractional-storage CDN servers are located close to or on the Internet backbone, and streaming the reconstructed content takes at least an order of magnitude longer than obtaining the fragments and reconstructing the content.

Abstract: Load-balancing an asymmetrical distributed erasure-coded system including fractional-storage CDN servers, storing, at a high storage gain, erasure-coded fragments encoded with a redundancy factor greater than one from segments, and a plurality of assembling devices, each obtaining fragments from a subgroup of the servers. The subgroups are selected from the servers still capable of increasing their fragment delivery throughput. Wherein not all of the servers have the same fragment delivery bandwidth capability, and the storage gain of each segment on each server is usually not strictly proportional to the bandwidth capability of the server, and the aggregated throughput used by the servers to deliver fragments may approach the aggregated bandwidth capabilities of the servers.

Abstract: Several methods and a system of a workload management of a concurrently accessed database server are disclosed. In one embodiment, a method includes applying a weight to a service class. The method also includes generating a priority of the service class. In addition, the method includes selecting a group based on the weight of the service class. The method further includes determining a priority level based on the priority of the service class. The method also includes generating a characteristic of a shadow process through the weight and the priority of the service class. In addition, the method includes executing a query.

Abstract: A system and method of massively parallel data processing are disclosed. In an embodiment, a method includes generating an interpretation of a customizable database request which includes an extensible computer process and providing an input guidance to available processors of an available computing environment. The method further includes automatically distributing an execution of the interpretation across the available computing environment operating concurrently and in parallel, wherein a component of the execution may be limited to at least a part of an input data. The method also includes automatically assembling a response using a distributed output of the execution.

Abstract: In one embodiment, a method includes concurrently executing a set of multiple queries, through a processor, to improve a resource usage within a data warehouse system. The method also includes permitting a group of users of the data warehouse system to simultaneously run a set of queries. In addition, the method includes applying a high-concurrency query operator to continuously optimize a large number of concurrent queries for a set of highly concurrent dynamic workloads.

Abstract: A method of controlling access to a network media by a plurality of stations, the method including determining a number of time slots; determining a number of slot cycles for each time slot, at least one of the time slots having more than one slot cycle; assigning each station one or more slot cycles in one or more time slots; and operating each of the stations by initializing an access timer to time out at the beginning of the station's assigned slot cycle(s) and transmitting data during the assigned slot cycle(s), the access timer being stopped whenever a station transmits over the network, and restarted at the end of transmission.

Abstract: A system and method for using failure casting to manage failures in computer system. In accordance with an embodiment, the system uses a failure casting hierarchy to cast failures of one type into failures of another type. In doing this, the system allows incidents, problems, or failures to be cast into a (typically smaller) set of failures, which the system knows how to handle. In accordance with a particular embodiment, failures can be cast into a category that is considered reboot-curable. If a failure is reboot-curable then rebooting the system will likely cure the problem. Examples include hardware failures, and reboot-specific methods that can be applied to disk failures and to failures within clusters of databases. The system can even be used to handle failures that were hitherto unforeseen—failures can be cast into known failures based on the failure symptoms, rather than any underlying cause.

Abstract: The present invention addresses the problem of partitioning database relations across a plurality of hosts in a shared-nothing cluster while minimizing communication costs. A new partitioning approach for database relations—join-partitioning—is introduced that focuses on relations and their dependencies to a priori partition the plurality of relations to the plurality of hosts such that each host can locally compute a large class of queries over its partitioned data in isolation at query time, independent of other hosts in the cluster. Such an approach thus overcomes the primary bottleneck, i.e., the network, in deploying database systems over shared-nothing clusters by allowing them to seamlessly scale linearly to tens of thousands of hosts and manage tens or hundreds of terabytes of data. This description is not intended to be a complete description of, or limit the scope of, the invention.

Abstract: An event tap associated with a server, such as a Web server, at a machine can transform a server event into a tuple, select a database node for the tuple, and place the tuple in a queue for that database node, and then flush the queue periodically directly into database notes. The use of an event tap can thus reduce the computational burden on the database while keeping the server event data in the database relatively fresh.

Abstract: A system including a digital appliance having a high data rate wideband RF transceiver operating in a microwave band for communicating digital data within quiescent periods of periodic noise and within quiescent periods within super cycle noise enclosing the periodic noise. The quiescent periods can also be used to control power management of the appliance as well as perform network control.
