Abstract: A vapor chamber is provided. The vapor chamber includes a first and a second plate cover, and a capillary structure, where the first and the second plate cover form an accommodating cavity. Capillary structures are in a shape of a long strip, and are arranged at intervals in the accommodating cavity in parallel. Two opposite surfaces of the capillary structure are respectively connected to the first and the second plate cover, to support the first plate cover and the second plate cover in an overlapping direction of the first plate cover and the second plate cover. A vapor channel is formed around the capillary structure filled with a working medium. The microstructure layer is introduced to an inner surface of the accommodating cavity and the capillary structure in the vapor chamber. In the vapor chamber, the liquid-phase working medium in the condensation region can return in time.

Abstract: A packet forwarding method and a network device are provided, and the method is applied to the network device. The network device includes a first virtual routing and forwarding (VRF) table and a second VRF table. The method includes: the network device receives a first packet. If the first packet carries tunnel attribute information, the network device forwards the first packet based on the first VRF table. The first VRF table includes one or more local routes, and next-hop outbound interfaces of the one or more local routes are all local outbound interfaces. The network device forwards the first packet based on the first VRF table, so that a packet from a tunnel may be forwarded to a local virtual machine for processing and may not be forwarded to another tunnel endpoint device, to avoid a routing loop during packet forwarding.

Abstract: This application provides a packet forwarding method and a network device. The method specifically includes: A first network device forwards a first packet from a second network device to a corresponding local virtual machine based on the virtual network identifier in the first packet, and does not need to forward the packet according to a virtual routing and forwarding VRF table. This prevents the packet from being forwarded to another network device again, and ensures normal forwarding of the packet.
