Abstract: The present disclosure relates to a traffic transmission control method, an electronic device, and a storage medium. The method includes: obtaining a central processing unit CPU consumption value consumed by each tenant traffic of a cloud network service transmitted via a virtual switch in a current statistical period, to obtain a CPU consumption value corresponding to each tenant; calculating a CPU consumption proportion among tenants based on the CPU consumption value and a CPU consumption value corresponding to each tenant accumulated in a historical statistical period; receiving outbound traffic of each tenant in a next statistical period of the current statistical period; and controlling the virtual switch to perform forwarding processing on the outbound traffic of each tenant in the next statistical period of the current statistical period based on the CPU consumption proportion among the tenants and a virtual switch forwarding performance proportion preconfigured for each tenant.

Abstract: Embodiments of the present application provide a remote direct memory access method and apparatus, and relate to the field of computer technologies. The method includes: receiving a first virtual extensible local area network (VXLAN) message sent by a first virtual machine to a second virtual machine through a VXLAN tunnel, where the first VXLAN message is generated by performing VXLAN encapsulation on a remote direct memory access (RDMA) over Converged Ethernet (RoCE) message; and performing VXLAN decapsulation on the first VXLAN message through a hardware programmable network interface card based on a virtual switch, to obtain a first RoCE message, and performing access control on the first RoCE message through the hardware programmable network interface card, where the hardware programmable network interface card based on the virtual switch is preconfigured based on software of the virtual switch.

Abstract: Embodiments of the present disclosure provide a packet forwarding method and device based on a cloud network, the method including: receiving a first packet sent by a source virtual machine to a destination virtual machine, parsing the first packet, replacing an Ethernet protocol header of the first packet with a preset private extension protocol header, setting each field in the private extension protocol header according to a business requirement, and performing encapsulation through a VXLAN protocol to generate a second packet; and forwarding the target traffic based on the second packet.
