Abstract: Embodiments of the present invention provide a data processing system and a data processing method. An MMIO address of a data request is obtained, where data stored in a PCIe storage device can be directly obtained from the MMIO address, and according to the MMIO address, a network adapter can directly read the data from the PCIe storage device of the data processing system, and transmit the data to a second data processing system, or directly write the data received from the second data processing system into the PCIe storage device. Therefore, the processing system can implement transmitting data directly from the PCIe storage device to the network adapter without using memory. During data transmission between the two data processing systems, a usage ratio of a resource, such as memory and a CPU, is reduced, and efficiency of data transmission is improved

Abstract: A packet forwarding method, device, and system for use in non-volatile memory express (NVMe) over fabric. According to the method, a first packet sent by a control device is received; a second packet is generated according to the first packet; a network port for forwarding the second packet is selected according to an identity of a target non-volatile memory; and the second packet is encapsulated into a packet that meets an NVMe over fabric forwarding requirement, and the encapsulated second packet is sent by using the selected network port.

Abstract: This application discloses a data transmission method and a device. The method includes: A sender endpiont constructes n streams through an interface provided by a QUIC protocol, and sets attribute information of the streams (or sets different attribute information for different data blocks in a same stream). The sender endpiont transfers the attribute information of the streams to a first network node by using a first extended frame (or transfers the attribute information of the different data blocks in the same stream by using a second extended frame). The first or second extended frame is a frame obtained by performing protocol extension on the QUIC protocol. After receiving the first or second extended frame, the first network node determines, according to a sending policy of the first network node, routing, caching, and distribution of a target data stream, and continues to deliver the attribute information.

Abstract: This application provides a subflow establishment method. A local-end device obtains an identifier of an operator currently accessed by a network interface card of the local end device. The local-end device obtains a plurality of IP addresses of a peer-end device and identifiers of operators to which the plurality of IP addresses are homed; and establishes, by matching a plurality of operators corresponding to the local-end device and the plurality of operators corresponding to the peer-end device, a subflow between an IP address pair homed to a same operator. In this way, the established subflow does not cross operators as far as possible. This reduces negative impact of cross-operator communication of some subflows on transmission performance of a multipath connection, thereby better leveraging an advantage of the multipath connection in transmission performance in
