    摘要： A remote direct memory access (RDMA) data transmission system includes a first network device in a first host and a second network device in a second host. The first network device may create a shared send queue (SSQ) used by a plurality of processes run by the first host, obtain an RDMA data transmission message of a first process from the SSQ, and encapsulate a first identifier corresponding to the first process into a first packet in which the RDMA data transmission message is encapsulated. The second network device is configured to encapsulate the first identifier into a second packet in which a feedback message is encapsulated.

    摘要： Ethernet link extension methods and devices provide, in one illustrative embodiment, an Ethernet link extender with physical medium attachment (PMA) circuits each having a transmitter and receiver that communicate with a respective node in a sequence of communication phases. The sequence includes at least an auto-negotiation phase and a subsequent training phase, the phases occurring simultaneously for both PMA circuits. In the auto-negotiation phase, the PMA circuits operate in a pass-through mode, rendering the extender transparent to the two nodes. In the training phase, the PMA circuits operate independently, sending training frames to their respective nodes based in part on received back-channel information and locally-determined training status information. The training phases may be prolonged if needed to provide a simultaneous transition to a frame-forwarding phase of the sequence.

    摘要： Described herein are systems and methods for traffic classification that integrate a plurality of different types of traffic classifiers in parallel so that there is little or no adverse effects on data path performance. The systems and methods also integrate a plurality of complementary tiered classifiers to improve or enhance the results of a primary classification technique. Results from the individual parallel and tiered traffic classifiers can be analyzed to determine an output classification. The resulting output traffic classification can be used to determine a preferred or desirable link between nodes on a network where the network includes parallel links or network paths between the nodes. The disclosed systems and methods may be particularly advantageous where the different network paths have different characteristics such as latency, capacity, congestion, cost, bandwidth, etc.
