摘要： A server fabric adapter (SFA) communication system is disclosed. In some embodiments, the SFA communication system comprises an SFA communicatively coupled to a plurality of controlling hosts, a plurality of endpoints, and a plurality of network ports. The SFA is configured to receive a network packet from a network port of the plurality of network ports; separate the network packet into different portions, each portion including a header or a payload; map each portion of the network packet to: (i) a controlling host of the plurality controlling hosts, the controlling host being designated as a destination controlling host, or (ii) an endpoint of the plurality of endpoints, the endpoint being designated as a destination endpoint; and forward a respective portion of the network packet to the destination controlling host or the destination endpoint.

摘要： Aspects of present disclosure include devices within a transmission path of streamed content forwarding received data packets of the stream to the next device or “hop” in the path prior to buffering the data packet at the device. In this method, typical buffering of the data stream may therefore occur at the destination device for presentation at a consuming device, while the devices along the transmission path may transmit a received packet before buffering. Further, devices along the path may also buffer the content stream after forwarding to fill subsequent requests for dropped data packets of the content stream. Also, in response to receiving the request for the content stream, a device may first transmit a portion of the contents of the gateway buffer to the requesting device to fill a respective buffer at the receiving device.

摘要： A packet is transmitted from a remote device over a communication network. A fragment detector detects one or more fragments in a field of the packet, where the field is associated with a session layer or higher abstraction layer of an open systems interconnect (OSI) model. Fragment information is extracted from the packet which indicates one or more of a last fragment index associated with a last fragment of one or more fragment in the packet and a fragment count indicative of a number of fragments associated with a message which is fragmented. Interrupts associated with the packet with other interrupts associated with other packets are coalesced based on one or more of the last fragment index and the fragment count.

摘要： Nodes within a network are configured to adapt to changing path states, due to congestion, node failures, and/or other factors. A node may selectively convey path information and/or other state information to another node by annotating the information into packets it receives from the other node. A node may selectively reflect these annotated packets back to the other node, or other nodes that subsequently receive these annotated packets may reflect them. A weighted cost multipathing selection technique is improved by dynamically adjusting weights of paths in response to feedback indicating the current state of the network topology, such as collected through these reflected packets. In an embodiment, certain packets that would have been dropped may instead be transformed into “special visibility” packets that may be stored and/or sent for analysis. In an embodiment, insight into the performance of a network device is enhanced through the use of programmable visibility engines.

摘要： Systems and methods for packet payload mapping for robust transmission of data are described. For example, methods may include receiving, using a network interface, packets that each respectively include a primary frame and one or more preceding frames from the sequence of frames of data that are separated from the primary frame in the sequence of frames by a respective multiple of a stride parameter; storing the frames of the packets in a buffer with entries that each hold the primary frame and the one or more preceding frames of a packet; reading a first frame from the buffer as the primary frame from one of the entries; determining that a packet with a primary frame that is a next frame in the sequence has been lost; and, responsive to the determination, reading the next frame from the buffer as a preceding frame from one of the entries.

摘要： A programmable switch includes a plurality of ports for communicating with devices on a network. Circuitry of the programmable switch is configured to receive a series of related messages from a first device on the network via at least one port, and determine whether one or more messages of the series of related messages have been received out-of-order based at least in part on a sequence number included in the one or more messages. The series of related messages are sent by the programmable switch to a second device via one or more ports in an order indicated by sequence numbers included in the series of related messages by delaying at least one message. According to one aspect, a network controller selects a programmable switch between the first device and the second device to serve as a message sequencer for reordering out-of-order messages using a stored network topology.
