摘要： A computer system with black hole management. The black hole management system shares black hole status information among connections that employ the same path. The black hole status information may indicate either that a black hole exists on the path or that communications have been performed successfully on the path, indicating that no black hole exists. By sharing this information, delays in transmission caused by black hole probing may be reduced. Additionally, status information for a connection is reset when information indicates that the connection has been altered. By resetting the status information, delays in transmission associated with sending reduced sized packets over connections for which black holes were previously detected but may have been eliminated by changes in the connection, are avoided.

摘要： Techniques are provided for adjusting to changes to the latency for a connection between two nodes on a network. In accordance with some embodiments, when a transmitting node encounters a retransmission timeout for a packet sent to a receiving node, the latency for the connection is newly measured and used to calculate a new retransmission timeout period for subsequent transmissions by the transmitting node. In some embodiments, the latency is not newly measured if a selective acknowledgement is received indicating that congestion on the network is only temporary.

摘要： Creating different congestion control modules (CCMs) that can be plugged into a network communications stack (e.g., a TCP/IP stack). Software abstractions defining transport control events, congestion control algorithms and other information may be exposed by an application programming interface, e.g., of an operating system, and these abstractions may be used to define a CCM. The network communications stack may be configured to select one of multiple available CCMs to control congestion for a given connection. This selection may be based on any of a variety of factors including, but not limited to: network environment; connection path characteristics; connection link characteristics; a value of a socket parameter of an application; other factors; and any suitable combination of the foregoing. Thus, CCMs may be selected and implemented on a per-connection basis.

摘要： Efficiently polling a DMA module to determine if the DMA copying of a packet payload to an application buffer is complete. For communication packets received from a network, a processing module may be configured to poll the DMA module at times when it is likely that the DMA copying of packet payloads is complete. Packets may be received and processed in batches. The polling of the DMA module for a packet belonging to a first batch may be deferred until the processing of a next batch. An exception may occur if a predefined amount of time elapses following the completion of the processing of the first batch before the next batch is received. In response to the predefined amount of time elapsing before the receipt of the next batch, the DMA module may be polled, i.e., prior to the next batch being processed.
