Abstract: This application discloses a VXLAN packet transmission method, a network device, and a system. After receiving a first packet, a first network device obtains a VNI corresponding to the first packet. The first network device encapsulates the VNI in an IPV6 header by encapsulating the IPV6 header in the first packet, to obtain a second packet. The first network device sends the second packet to a second network device, so that the second network device forwards the packet based on the VNI included in the IPV6 header. In this application, the IPV6 header is used to carry the VNI, and no additional UDP header needs to be encapsulated to carry the VNI.

Abstract: A packet forwarding method and apparatus are described that pertain to the field of communication technologies. During selecting, from outbound interfaces of a plurality of forwarding chips, an outbound interface used for packet forwarding, a chassis-shaped device considers both: a role of the outbound interface (whether the outbound interface is an outbound interface of a shortest path or an outbound interface of a non-shortest path), and a congested state of the outbound interface. As such, the chassis-shaped device flexibly selects a forwarding path for a data packet based on a congestion situation of the forwarding path. In this way, an application of an adaptive routing technology is extended to the chassis-shaped device.

The radiator includes a first position and a second position, where a distance between the first position and the open end along the radiator is a quarter of a target wavelength, and a distance between the second position and the first feed point along the radiator is a half of the target wavelength. The first feed point is disposed at a position that deviates from the first position by a first preset value. The second feed point is disposed at a position that deviates from the second position by a second preset value.
