    摘要： Generally, this disclosure provides systems, methods and computer readable media for management of sockets and device queues for reduced latency packet processing. The method may include maintaining a unique-list comprising entries identifying device queues and an associated unique socket for each of the device queues, the unique socket selected from a plurality of sockets configured to receive packets; busy-polling the device queues on the unique-list; receiving a packet from one of the plurality of sockets; and updating the unique-list in response to detecting that the received packet was provided by an interrupt processing module. The updating may include identifying a device queue associated with the received packet; identifying a socket associated with the received packet; and if the identified device queue is not on one of the entries on the unique-list, creating a new entry on the unique-list, the new entry comprising the identified device queue and the identified socket.

    摘要： Methods and apparatus for implementing flow control with reduced buffer usage for network devices. In response to detection of flow control events, transmission of a data unit or segment such as an Ethernet frame is preempted in favor of a flow control message, resulting in aborting transmission of the frame. Data corresponding to the entirety of the frame is buffered at the transmitting station until the frame has been transmitted (or after a delay), enabling retransmission of the aborted frame. Preemption of frames in favor of flow control messages results in earlier responses to flow control events, enabling the size of buffers to be reduced.

    摘要： Generally, this disclosure provides devices, methods and computer readable media for packet processing with reduced latency. The device may include a data queue to store data descriptors associated with data packets, the data packets to be transferred between a network and a driver circuit. The device may also include an interrupt generation circuit to generate an interrupt to the driver circuit. The interrupt may be generated in response to a combination of an expiration of a delay timer and a non-empty condition of the data queue. The device may further include an interrupt delay register to enable the driver circuit to reset the delay timer, the reset postponing the interrupt generation.

    摘要： An embodiment may include circuitry to facilitate, at least in part, a first network interface controller (NIC) in a client to be capable of accessing, via a second NIC in a server that is remote from the client and in a manner that is independent of an operating system environment in the server, at least one command interface of another controller of the server. The command interface may include at least one controller command queue. Such accessing may include writing at least one queue element to the at least one command queue to command the another controller to perform at least one operation associated with the another controller. The another controller may perform the at least one operation in response, at least in part, to the at least one queue element. Many alternatives, variations, and modifications are possible.

    摘要： Certain aspects of a method and system for configuring a plurality of network interfaces that share a physical interface (PHY) may include a system comprising one or more physical network interface controllers (NICs) and two or more virtual NICs. One or more drivers associated with each of the virtual NICs that share one or more Ethernet ports associated with the physical NICs may be synchronized based on controlling one or more parameters associated with one or more Ethernet ports. One or more wake on LAN (WoL) patterns associated with each of the drivers may be detected at one or more Ethernet ports. A wake up signal may be communicated to one or more drivers associated with the detected WoL patterns. One of the drivers may be appointed to be a port master driver. If a failure of the appointed port master driver is detected, another driver may be appointed to be the port master driver.

    摘要： Methods and apparatus for implementing notification by network elements of packet drops. In response to determining a packet is to be dropped, a network element such as a switch or router determines the source of the packet and returns a dropped packet notification message to the source. Upon receipt of notification, networking software or embedded hardware on the source causes the dropped packet to be retransmitted. The notification may also be sent from the network element to the destination computer to inform networking software or embedded logic implemented by the destination computer that the packet was dropped and notification to the source has been sent, thus alleviating the destination from needing to send a Selective ACKnowledge (SACK) message to inform the source the packet was not delivered.
