    摘要： Embodiments are configured to provide communication features, including providing channel condition estimates for a communication path, such as packet loss, jitter, and/or available bandwidth, but are not so limited. In an embodiment, a method uses aspects of in-band data packets to provide channel condition estimates. In one embodiment, a system includes a bandwidth estimation component that operates to classify payload packets as part of performing capacity estimation and available bandwidth estimation operations.

    摘要： Transmission delays are minimized when packets are transmitted from a source computer over a network to a destination computer. The source computer measures the network's available bandwidth, forms a sequence of output packets from a sequence of data packets, and transmits the output packets over the network to the destination computer, where the transmission rate is ramped up to the measured bandwidth. In conjunction with the transmission, the source computer monitors a transmission delay indicator which it computes using acknowledgement packets it receives from the destination computer. Whenever the indicator specifies that the transmission delay is increasing, the source computer reduces the transmission rate until the indicator specifies that the delay is unchanged. The source computer dynamically decides whether each output packet will be a forward error correction packet or a single data packet, where the decision is based on minimizing the expected transmission delays.

    摘要： Described is a technology by which a relay is coupled (e.g., by a wire) to a network and (e.g., by a wireless link) to an endpoint. Incoming data packets directed towards the endpoint are processed by the relay according to an error correction scheme, such as one that replicates packets. The reprocessed packets, which in general are more robust against packet loss, are then sent to the endpoint. For outgoing data packets received from the endpoint, the relay reprocesses the outgoing packets based upon the error correction scheme, such as to remove redundant packets before transmitting them to the network over the wire. Also described are various error correction schemes, and various types of computing devices that may be used as relays. The relay may be built into the network infrastructure, and/or a directory service may be employed to automatically find a suitable relay node for an endpoint device.

    摘要： The subject disclosure is directed towards a data deduplication technology in which a hash index service's index and/or indexing operations are adaptable to balance deduplication performance savings, throughput and resource consumption. The indexing service may employ hierarchical chunking using different levels of granularity corresponding to chunk size, a sampled compact index table that contains compact signatures for less than all of the hash index's (or subspace's) hash values, and/or selective subspace indexing based on similarity of a subspace's data to another subspace's data and/or to incoming data chunks.
