摘要:
A network provides distributed client services based on participation in respective resource groups by computing nodes, each resource group including a corresponding resource requirement for any computing node that joins the corresponding resource group for execution of the corresponding distributed client service. Each computing node, in response to determining its corresponding available node capacity, is configured for selectively creating and joining at least one new resource group for execution of a corresponding distributed client service having a corresponding resource requirement, and/or selectively joining at least one of the available resource groups, based on the corresponding available node capacity satisfying the corresponding resource requirement. Each distributed client service also includes service attributes that define parameters for execution of the distributed client service, and data attributes that define the attributes required for data to be used in the distributed client service.

Distributed data, having been stored in a distributed storage system as a collection of distributed data elements, is recovered based on connection of multiple user nodes, each user node having stored selected distributed data elements as a corresponding portion of the distributed data during replication of the distributed data elements throughout the distributed storage system. Each distributed data element is identifiable by a corresponding unique object identifier (OID). Each user node includes a discovery resource for discovering reachable user nodes, a local cache configured for identifying at least the corresponding portion of the distributed data based on the respective OIDs, and an identification service module configured for resolving a data object to a corresponding OID, via the corresponding local cache, or based on sending a query to the reachable user nodes. Hence, user nodes can recover distributed data based on exchanging resolution information and OID information.

A network has network nodes for storage of respective copies of a data file. One of the network nodes has a corresponding unique locality control object for the copies of the data file. The locality control object provides authority for the one network node to control storing and modifying any of the copies of the data file. The other network nodes lacking the locality control object must obtain permission from the one network node before modifying any one of the copies of the data file. The network nodes also can negotiate for passing the locality control object from the one network node to another one of the network nodes based on determined locality attributes associated with the copies of the data file.

Advanced communication services are deployed for a user device, such as a VoIP telephony device, based on utilizing a model view controller architecture within a network system (e.g., a VoIP system) configured for communication with the VoIP telephony device. The VoIP telephony device and a service node of the VoIP system each are configured for executing at least one corresponding model object, view object, and controller object of a prescribed network service. The model object, view object, and controller object each are configured for utilizing transaction-based messages associated with the prescribed network service. Moreover, the service node is configured for selectively transferring any one of the model object, view object, and the controller object to another node, for example the VoIP telephony device or another network node, and terminating execution of the transferred object, without interruption in service for the user.

A network-enabled user interface device, for example a VoIP telephony device, includes a display, a user input interface, an interface controller, and an application controller. The interface controller is configured for generating display elements for the display, controlling the user input interface based on received commands, and outputting responses to the application controller. The application controller is configured for outputting the commands to the interface controller based on application operations executed locally (i.e., within the user interface device), or remotely (e.g., by a server in communication with the user interface device). Remote application operations may include communications between the application controller and the remote server. The interface controller also may generate the display elements based on messages received from the network. Hence, the network-enabled user interface device can provide to the user interaction with arbitrary applications, executed locally or remotely, enabling any executable application to be provided to the user, independent of user action.

A network provides distributed computing services based on participation in respective resource groups by computing nodes, each resource group including a corresponding resource requirement for any computing node that joins the corresponding resource group for execution of the corresponding distributed computing service. Each computing node, in response to determining its corresponding available node capacity, is configured for selectively creating and joining at least one new resource group for execution of a corresponding distributed computing service having a corresponding resource requirement, and/or selectively joining at least one of the available resource groups, based on the corresponding available node capacity satisfying the corresponding resource requirement. Each computing node also is configured for selectively leaving any one of the joined resource groups based on determined conditions. Hence, each computing node may choose to participate in as many resource groups as needed for respective computing services, based on the corresponding available node capacity.
摘要:
Each data file of a distributed file system is identified by a corresponding globally-unique object identifier that is independent of any attribute of the data file. A node in the distributed file system has a file system that includes a plurality of directory entries, where each directory entry has a file name field, an attributes field, and an object identifier field configured for specifying a globally-unique object identifier. The globally-unique object identifier is universally reachable by any node of the distributed file system and uniquely identifies the data file, enabling the data file to be universally identifiable by any node based on the corresponding object identifier. The data file can be stored independently of a device file system based on providing a resolution between the data file name and its object identifier, followed by a resolution between the object identifier and a selected location for the data file.

In one embodiment, a method comprises supplying, by a network node to a peer network node, a randomization seed assigned to the network node for generating a prescribed sequence of pseudorandom numbers according to a prescribed pseudorandom number generation function; encoding each data block having a corresponding position in an ordered sequence of a stream of data blocks, by the network node into a corresponding differentially-encoded data block based on applying a product of the corresponding data block and the corresponding pseudorandom number, having the corresponding position in the prescribed sequence, to a corresponding successively-preceding differentially-encoded data block from the prescribed ordered sequence, the data block recoverable solely based on a determined difference between the corresponding differentially-encoded data block and the corresponding successively-preceding differentially-encoded data block relative to the corresponding pseudorandom number; and outputting each differentially-encoded data block in a corresponding packet that identifies the network node and the corresponding position.
