Abstract: A method for distributed routing of a packet in a network is provided. The network includes a controller, a first server, a second server, and a first switch. The method includes: obtaining identifiers of the two servers in the network and network connection information; determining whether the two servers are in two different subnets of the network and whether the two different subnets are configured on a same router according to the identifiers of the two servers and the network connection information of the two servers; when it is determined that that the two servers are in two different subnets of the network and the two different subnets are configured on a same router, instructing the first switch to modify a packet header of a packet sent by the first server to the second server and forward the modified packet to the second server.

Abstract: This application discloses a data packet processing method applied to a computing device in software-defined networking. After receiving a data packet of a data flow, a NIC in the computing device queries a flow table set according to matching information of the data packet; and if a flow table is obtained from the flow table set, the NIC processes the data packet according to the flow table; or if no flow table can be obtained from the flow table set, the NIC sends the data packet to a virtual switch, and the virtual switch obtains a flow table corresponding to the data flow, and saves the flow table into the flow table set, so that the NIC can directly process a subsequent data packet of the data flow. An operating load of the virtual switch is reduced, and operating efficiency of the computing device is improved.
