摘要： A serverless distributed file system manages the storage of files and directories using one or more directory groups. The directories may be managed using Byzantine-fault-tolerant groups, whereas files are managed without using Byzantine-fault-tolerant groups. Additionally, the file system may employ a hierarchical namespace to store files. Furthermore, the directory group may employ a plurality of locks to control access to objects (e.g., files and directories) in each directory.

摘要： Cryptographic protocols and methods of employing the same are described. The described protocols advantageously enable two or more identical encryptable objects that are coded for encryption with different keys to be identified as identical without access to either the unencrypted objects or the keys that are used in the encryption process. Additionally, the protocols enable two or more identical encryptable objects to be processed with different encryption keys, yet be stored in a manner so that the total required storage space is proportional to the space that is required to store a single encryptable object, plus a constant amount for each distinct encryption key. In various embodiments, the encryptable objects comprise files and the cryptographic protocols enable encrypted files to be used in connection with single instance store (SIS) systems.

摘要： Potentially identical objects (e.g., files) are located across multiple computers based on stochastic partitioning of workload. For each of a plurality of objects stored on a plurality of computers in a network, a portion of object information corresponding to the object is selected. The object information can be generated in a variety of manners (e.g., based on hashing the object, based on characteristics of the object, and so forth). Any of a variety of portions of the object information can be used (e.g., the least significant bits of the object information). A stochastic partitioning process is then used to identify which of the plurality of computers to communicate the object information to for identification of potentially identical objects on the plurality of computers.

摘要： A system is provided for servicing requests by a mobile controller to utilize stationary or mobile resources present within a partitioned communication cell such as an office or room in a building. The mobile controller has a control signal mechanism for generating control request signals to modify behavior of the stationary or mobile resource, with the range of the control request signals substantially limited to the partitioned communication cell. A room agent receives and acts upon the control request signals after dynamically determining availability of both mobile resources entering and exiting the partitioned communication cell and stationary resources already present in the partitioned communication cell. In operation, the room agent is configured to grant requests for utilization of mobile and stationary resources located within the partitioned communication cell when predetermined contextual attributes within the partitioned communication cell are consistent with previously specified interaction policies.
