摘要: A technique for resource allocation in a wireless network (for example, an access point type wireless network), which supports concurrent communication on a band of channels, is provided. The technique includes accepting connectivity information for the network that supports concurrent communication on the band of channels. A conflict graph is generated from the connectivity information. The generated conflict graph models concurrent communication on the band of channels. A linear programming approach, which incorporates information form the conflict graph and rate requirements for nodes of the network, can be utilized to maximize throughput of the network.

摘要: Difficulties associated with choosing advantageous network routes between server and clients are mitigated by a routing system that is devised to use many routing path sets, where respective sets comprise a number of routing paths covering all of the clients, including through other clients. A server may then apportion a data stream among all of the routing path sets. The server may also detect the performance of the computer network while sending the data stream between clients, and may adjust the apportionment of the routing path sets including the route. The clients may also be configured to operate as servers of other data streams, such as in a videoconferencing session, for example, and may be configured to send detected route performance information along with the portions of the various data streams.

摘要: The described implementations relate to distributed network management and more particularly to enhancing distributed network utility. One technique selects multiple trees to distribute content to multiple receivers in a session where individual receivers can receive the distributed content at one of a plurality of rates. The technique further adjustably allocates content distribution across the multiple trees to increase a sum of utilities of the multiple receivers.

摘要: Described is using flash memory, RAM-based data structures and mechanisms to provide a flash store for caching data items (e.g., key-value pairs) in flash pages. A RAM-based index maps data items to flash pages, and a RAM-based write buffer maintains data items to be written to the flash store, e.g., when a full page can be written. A recycle mechanism makes used pages in the flash store available by destaging a data item to a hard disk or reinserting it into the write buffer, based on its access pattern. The flash store may be used in a data deduplication system, in which the data items comprise chunk-identifier, metadata pairs, in which each chunk-identifier corresponds to a hash of a chunk of data that indicates. The RAM and flash are accessed with the chunk-identifier (e.g., as a key) to determine whether a chunk is a new chunk or a duplicate.

摘要: The subject disclosure is directed towards a data deduplication technology in which a hash index service's index maintains a hash index in a secondary storage device such as a hard drive, along with a compact index table and look-ahead cache in RAM that operate to reduce the I/O to access the secondary storage device during deduplication operations. Also described is a session cache for maintaining data during a deduplication session, and encoding of a read-only compact index table for efficiency.
