Abstract: A packet forwarding method. In this method, a forwarding node receives a packet, obtains a target service resource status advertised by each service node in a plurality of service nodes, selects a target service node from the plurality of service nodes based on the target service resource status advertised by the service node, and forwards the packet to the target service node. In other words, the forwarding node can sense a service resource status advertised by the service node, and the service resource status can indicate a resource usage status of a service resource managed by the service node. An actual processing capability of the service node can be sensed based on the resource usage status.

Abstract: Embodiments of the present disclosure disclose an antenna, and relate to the field of wireless communications. In the antenna, radiation parts of the antenna are disposed on at least two layers of circuit boards on a printed circuit board: a top layer circuit board and a first layer circuit board, so that lengths of the radiation parts of the antenna are reduced, and space occupied by a printed wire of the antenna on the PCB is reduced. Therefore, reducing a PCB size becomes possible, a size of a terminal using the reduced-size PCB may also be correspondingly reduced, and the terminal may be further miniaturized.
