Abstract: A data transmission method, implemented by a network device, includes sending a probe packet to a log server, determining whether the log server can receive a packet responsive to whether the network device receives a probe response packet from the log server, and sending a log packet to the log server when the log server can receive a packet. The log packet includes a correspondence between a public Internet Protocol (IP) address and a private IP address.

Abstract: A packet processing method, and a device and a system includes receiving, by a provider edge (PE) device, a first virtual extensible local area network (VxLAN) encapsulated packet sent by a network virtualization edge (NVE) device, where the PE device and the NVE device are located in a same data center (DC), and the first VxLAN encapsulated packet includes a first VxLAN network identifier (VNI); parsing, by the PE device, the first VxLAN encapsulated packet to obtain the first VNI; obtaining, according to a correspondence between a VNI and a virtual routing and forwarding (VRF) table, a first VRF table that corresponds to the first VNI; searching, by the PE device, the first VRF table for a route according to a destination Internet Protocol (IP) address of the first VxLAN encapsulated packet; and forwarding the first VxLAN encapsulated packet.

Abstract: A communications method and apparatus for a Virtual Extensible Local Area Network (VXLAN), where the method includes receiving, by a first layer-3 gateway device, host routing information from a second layer-3 gateway device, where the host routing information includes an Internet Protocol (IP) address of a first host, a media access control (MAC) address of the first host, and a VXLAN tunnel end point (VTEP) identifier of a next hop of the first layer-3 gateway device and that exists when the first layer-3 gateway device sends information to the first host, and forwarding, by the first layer-3 gateway device, a traffic packet destined for the first host or acting, by the first layer-3 gateway device, as an Address Resolution Protocol (ARP) proxy for the first host, based on the host routing information. Hence, traffic waste can be reduced.
