A map-reduce compatible distributed file system that consists of successive component layers that each provide the basis on which the next layer is built provides transactional read-write-update semantics with file chunk replication and huge file-create rates. Containers provide the fundamental basis for data replication, relocation, and transactional updates. A container location database allows containers to be found among all file servers, as well as defining precedence among replicas of containers to organize transactional updates of container contents. Volumes facilitate control of data placement, creation of snapshots and mirrors, and retention of a variety of control and policy information. Also addressed is the use of distributed transactions in a map-reduce system; the use of local and distributed snapshots; replication, including techniques for reconciling the divergence of replicated data after a crash; and mirroring.

Map-reduce ready distributed file system

A map-reduce compatible distributed file system that consists of successive component layers that each provide the basis on which the next layer is built provides transactional read-write-update semantics with file chunk replication and huge file-create rates. A primitive storage layer (storage pools) knits together raw block stores and provides a storage mechanism for containers and transaction logs. Storage pools are manipulated by individual file servers. Containers provide the fundamental basis for data replication, relocation, and transactional updates. A container location database allows containers to be found among all file servers, as well as defining precedence among replicas of containers to organize transactional updates of container contents. Volumes facilitate control of data placement, creation of snapshots and mirrors, and retention of a variety of control and policy information. Key-value stores relate keys to data for such purposes as directories, container location maps, and offset maps in compressed files.

Methods are disclosed for controlling mobile computing devices such as laptops, PDAs and cellular telephones, based on their location. A mobile computing device may include a software-rendered map of defined geographic regions, location handlers for defining behavior of a mobile device in a given geographic region, and a location handling engine for determining when a new geographic zone has been entered and exited, and for executing and terminating location handlers accordingly.

Location based, software control of mobile devices

A method and apparatus for supporting data connectivity with a roaming partner when a communication device is outside a service provider's range of coverage is provided. In one aspect, a user can select and store a roaming partner that is capable of data communication. While roaming, the communication device will display the data-roaming partners that are currently available within the communication range of the device and the user can choose one of these data-roaming partners and store the data-roaming partner information in memory. Upon re-entering the region within communication range of that roaming partner, the device can communicate with the roaming partner of choice rather than the roaming partner ordinarily selected by the device as a default.

Stored user selectable preferences for supporting data roaming in GPRS networks

Network connection information is requested by a wireless wide area network device via the internet. Such information may include configuration information, data roaming partner information, and/or cost information regarding roaming partner connection and/or a subscriber plan related to the wireless wide area network. To retrieve the information, the wireless device sends a request to a redirection server, which in turn provides an internet address for a provisioning server, or instructs a provisioning server to provide the network configuration information to the wireless device. A user and/or the wireless device may use the network connection information when deciding whether and/or how to connect to the network. A network provider may use methods disclosed herein to efficiently update wireless devices that subscribe to the network. The network provider may provide selected network connection information based on information regarding the wireless device, such as the user identification.

Automatically provisioning a WWAN device

A method, system, and computer-readable medium for seamlessly updating connection parameters that allow a communications device of a host machine to connect to a Wireless Wide Area Network. Users are allowed to edit certain parameters, and these changes are stored in persistent storage along with a unique identifier for the set that was edited. At connection time, the user's edits override the defaults pre-provisioned by the network operator and stored on the device. The operator can also remotely edit the parameters, after which the user's changes are overwritten with the new defaults. Thus, the invention is capable of seamlessly handling updates to the connection parameters by both the user and the network operator.
