Abstract: A data packet forwarding solution, which relates to the field of network transmission. A virtual switch in the solution saves a flow entry as an aging flow entry deleted from a flow table in a switch, and receives a reporting data packet generated according to a forwarding data packet when the forwarding data packet fails to match each flow entry in the flow table in the switch and a secure channel between the switch and the controller is faulty, delivers an aging flow entry matching the reporting data packet from an aging flow table to the switch, where the aging flow table includes one or more flow entries that are deleted as aging flow entries from a flow table in the switch.

Abstract: The present disclosure relates to a data transmission method and apparatus in an optoelectronic hybrid network. The method is: receiving an RDMA transmission request, and determining an RDMA transmission type and a to-be-transmitted data volume for data transmission according to the RDMA transmission request; determining a preset encapsulation format corresponding to the RDMA transmission type for data transmission and the to-be-transmitted data volume for data transmission; receiving to-be-transmitted data and encapsulating the to-be-transmitted data into a to-be-transmitted data packet of the determined preset encapsulation format; selecting a switching link for data transmission from an optical switching link and an electrical switching link according to a size of the to-be-transmitted data packet; and sending the to-be-transmitted data packet to a peer end based on the selected switching link for data transmission. Therefore, a proper switching link can be selected each time RDMA transmission for data transmission is performed.
