Abstract: Embodiments of this application disclose a route advertisement method, a route loop check method, and a device, so as to resolve a route loop problem in a network, and improve reliability of service packet transmission. The route advertisement method includes the following steps: A first network device receives a first route advertisement message, where a first field of the first route advertisement message includes a device identifier, and routing information included in the first route advertisement message comes from a device corresponding to the device identifier. The first network device generates a second route advertisement message based on the first route advertisement message, where a second field of the second route advertisement message includes the device identifier, and the first field and the second field are different fields. The first network device sends the second route advertisement message to a second network device.

Abstract: A communications device is provided, including a metal carrier having a mounting plane with at least one mounting area, and further includes an antenna element disposed in each mounting area. The mounting area is where the mounting plane intersects a circle centered at a feedpoint of the antenna element in the area and whose radius does not exceed a specified radius. When a boundary line of the mounting area includes a boundary line, a distance from the feedpoint to the boundary line is less than or equal to a specified distance; and/or when a boundary line of the mounting area includes a vertex of the mounting plane, a distance from the feedpoint to the vertex is less than or equal to a specified distance. A feed position on the antenna element is designed to obtain relatively good antenna roundness performance and enhance an antenna signal coverage effect.

Abstract: A service system and a memory management method and apparatus are provided. The service system includes a plurality of service nodes. A memory of at least one of the plurality of service nodes is divided into a local resource and a global resource. The local resource is used to provide memory storage space for a local service node, the global resource of the at least one service node forms a memory pool, and the memory pool is used to provide memory storage space for the plurality of service nodes. When a specific condition is satisfied, at least a part of space in the local resource is transferred to the memory pool.

Abstract: A dual-polarized antenna, an antenna array, and a communications device are disclosed. The dual-polarized antenna includes a base board, a horizontally polarized antenna, and a vertically polarized antenna. The substrate includes a first substrate and a plurality of second substrates stacked on the first substrate. The horizontally polarized antenna includes a first radiating element disposed on the first substrate, and a first feeding unit that feeds the first radiating element. The vertically polarized unit includes a second radiating element and a second feeding unit that feeds the second radiating element. The second radiating element includes a first metal patch disposed on each second substrate. In the foregoing technical solution, the base board formed by the stacked substrates is used as a support part, so that the horizontally polarized antenna and the vertically polarized antenna are disposed on the base board, thereby reducing space occupied by the dual-polarized antenna.
