Abstract: A communication method includes obtaining, by a source remote direct memory access (RDMA) network interface card (RNIC), to-be-transmitted data sent by a source virtual RNIC (vRNIC), obtaining, by the source RNIC, identity indication information of a destination vRNIC and packet forwarding information, and encapsulating, by the source RNIC, the to-be-transmitted data to obtain a target packet, and sending the target packet to a destination RNIC, where the destination vRNIC is a vRNIC running on the destination RNIC.

Abstract: A method for determining an intermediate routing node, including: determining at least one intermediate routing node that is used to transfer to-be-transmitted data between the two routing nodes when there is a fault in a communication path between two routing nodes, adding a channel dependency relationship between a to-be-verified intermediate routing node and the two routing nodes to a channel dependency graph of a routing network in which this fault has not occurred in order to enable the channel dependency graph to become an updated channel dependency graph, and determining the to-be-verified intermediate routing node as a final intermediate routing node that is used to transfer the to-be-transmitted data when the updated channel dependency graph does not have a dependency relationship loop. The determined intermediate routing node can be used to transfer to-be-transmitted data, which improves resource utilization of a routing network.

Abstract: A data transmission method implemented by a network device, where the data transmission method includes receiving a first data packet sent by a transmit end, buffering the first data packet to a low-priority queue when the first data packet is sent by the transmit end during a first round-trip time (RTT) of a data transmission phase between the transmit end and a receive end, receiving a second data packet from the transmit end, buffering the second data packet to a high-priority queue when the second data packet is not sent by the transmit end during the first RTT, and forwarding the second data packet in the high-priority queue before the first data packet in the low-priority queue.

Abstract: A method and an apparatus for notifying a network abnormality are provided. An OpenFlow switch detects whether an abnormality occurs in an OpenFlow network. The OpenFlow switch sends a first asynchronous message for describing the abnormality occurring in the OpenFlow network to a controller when detecting an abnormality occurring in the OpenFlow network, so that the controller processes, according to the first asynchronous message, the abnormality occurring in the OpenFlow network. In this way, the abnormality in the network is notified in time, thereby improving efficiency in processing the abnormality in the OpenFlow network. A technical problem in the prior art that an abnormality occurring in an OpenFlow network and caused by an unexpected event cannot be notified in time, so that the abnormality occurring in the OpenFlow network cannot be processed in time and efficiency in processing the abnormality occurring in the OpenFlow network is relatively low is solved.
