摘要： A wireless network metric region in a wireless network is determined using a node metric region and a performance metric. The node metric region, which includes a boundary of the node metric region, for each node is estimated and the performance metric for the node metric region for each node is measured. The boundary of the node metric region for each node is adjusted based on the measured performance metric and then the wireless network metric region for the wireless network is determined based on the adjusted boundaries of the node metric region for each node.

摘要： Windowed backward key rotation. A user is provided information that allows determining a limited number of previous keys in a series of keys from a later key in the series. A key in the series is generated, based at least in part on the information provided to the user. The key in the series is provided to the user. The user determines at least one key in the limited number of previous keys in the series by applying the information to the key in the series.

摘要： A method of providing protocol virtualization for a network file system. In particular, at least one virtual file server is established in the data path between the clients and the physical file systems. The virtual file server presents a virtualized name space and a virtualized ID space to the clients, the virtualized name and ID space representing the physical files on the physical file servers. To the clients, the virtual file server appears to be file server. To the physical file servers, the virtual file server appears to be a client. Junction directories permit the virtual file servers to combine physically separate directories to appear as one, and permit migration of objects between the physical file servers without perception by the clients.

摘要： A method and apparatus is used to divide a storage volume into shards. The division is made using a directed graph having a vertex for each block in the storage volume and directed-edges between pairs of vertices representing a shard of blocks, associating a weight with each directed edge that represents the dissimilarity for the shard of blocks between the corresponding pair of vertices, selecting a maximum number of shards (K) for dividing the storage volume, identifying a minimum aggregate weight associated with a current vertex for a combination of no more than K shards, performing the identification of the minimum aggregate weight for vertices in the directed graph, and picking the smallest aggregated weight associated with the last vertex to determine a sharding that spans the storage volume and provides a minimal dissimilarity among no more than K shards of blocks.
