Each submersible pump is controlled by one corresponding automatic water level controller to transport the treated water to the reclaimed water-use sites.

Abstract: In an embodiment, described herein is a system and method for discovering backups of a database running on a database host, for use by a centralized backup system to validate backup compliance. A report agent executing on the database host can implement a discovery process configured to gather metadata for the backups of the database from a number of dynamic performance views of the database. The metadata is recorded in a control file of the database, and can include one or more commands used by the backup tool to create the backups. The report agent can categorize the metadata into one or more groups based on the backup commands, map backup files associated with each backup to that backup, create a backup report to describe the mapping information and additional information for each backup, and send the backup report to the centralized backup system.

The credit system also decreases the credit for the user based on the amount of data downloaded by the peer node associated with the user.

Abstract: One embodiment provides a method and a system for expediting content delivery in a peer-to-peer overlay network. A local cache and directory server caches a multiplicity of segments for multi-media content, and maintains a mapping between cacheable content and one or more local partner nodes that transiently stage segments for the cacheable content. The local cache and directory server receives a request identifying requested content, which may or may not be cached or mapped. The cache and directory server determines a match to the requested content in the mapping and sends a list of local partner nodes that transiently stage segments for the requested content based on the match.

Abstract: A system for delivering streamed content over a large digital network such as the Internet. Distributed functionality executes on nodes in the network to achieve functions such as assigning partner nodes for transfer of content to or from a target node, scheduling transfer operations among nodes, adding or removing nodes from the network, maintaining security, and other operations. Different embodiments may use one or more of the functional features. In a preferred embodiment, video content is segmented and streamed through multi-path routing. An overlay network uses nodes in partnership groups so that a target node can obtain segments from multiple sources. Partner nodes can provide the segments within a given time window, including simultaneous delivery from multiple partner nodes, so that a more reliable data stream is supported.
