摘要： A network communication device can implement configurable network socket retransmission timeout parameters on a per socket basis. In one embodiment, it is determined, at a first network device, whether to define a network socket with a custom or a default retransmission timeout value to transmit data to a second network device. In response to determining to define the network socket with the custom retransmission timeout value, the network socket is defined with the custom retransmission timeout value, the data is transmitted to the second network device, and it is determined whether response data is received from the second network device prior to expiration of a time period associated with the custom retransmission timeout value. In response to determining that the response data is not received from the second network device prior to the expiration of the corresponding time period, the data is retransmitted to the second network device.

摘要： Network adapter use of an interface specific buffer is managed so that their combined use with non-interface specific buffers has a reduced impact, such as when an interface specific buffer becomes full. If an attempt fails by a protocol stack of an operating system to buffer information for a packet in an interface specific buffer, an offset marks the end of the use of the interface specific buffer for the packet and a non-interface specific buffer is used to store the remaining information for the packet. During transmission of the packet, the offset is read by a network adapter driver to take advantage of reduced processing for sending information from the interface specific buffer and to identify information that need additional processing for transmission from the non-interface specific buffer.

摘要： A network device can implement configurable socket aggregation to enable segmentation offload in the network device. In one embodiment, it is determined, at the network device, to create a network socket for an application of the network device to initiate a network connection for the application. Socket aggregation parameters are determined for the network socket associated with the application. The network socket is defined based, at least in part, on the socket aggregation parameters. A plurality of packets received from the application associated with the network socket are aggregated. It is determined, based on said aggregating the plurality of packets, whether at least one aggregation limit associated with the socket aggregation parameters is reached. An aggregate packet is provided to a network adapter of the network device to perform segmentation offload in response to said determining that at least one aggregation limit associated with the socket aggregation parameters is reached.

摘要： Various systems, processes, and products may be used to manage the transmission and reception of messages. In particular implementations, a system, process, and product for managing message transmission and reception may include the ability to receive a plurality of messages to be transmitted over a communication network, wherein some of the messages have a higher priority and some of the messages have a lower priority, and enqueue descriptors for the messages in a direct memory access queue. The system, process, and product may also include the ability to determine whether an overrun of the queue has occurred, analyze the queue if an overrun has occurred to determine if lower priority messages are associated with any of the descriptors in the queue, and replace, if descriptors for lower priority messages are in the queue, the descriptors for the lower priority messages with descriptors for higher priority messages.
