Abstract: Embodiments of the present invention disclose a method, an apparatus, and a system for selecting a network device. The method includes: receiving, by a second network device, a network device selection message sent by a first network device, where the network device selection message contains a VLAN mapping capability identifier of the first network device; and selecting, by the second network device, according to the VLAN mapping capability identifier and local VLAN mapping capability, a network device for executing VLAN mapping. By using the technical solutions provided in the embodiments of the present invention, execution of VLAN mapping for a bidirectional pseudo wire (PW) between two network devices on a same network device may be implemented, and there are only two VLAN identifiers on the bidirectional PW, thereby ensuring consistency of VLAN mapping and making it simpler and easier to maintain and detect the PW.

Abstract: An apparatus includes a program instructing hardware and a computer readable storage medium coupled to the hardware and storing programming instructions for execution by the hardware. The programming instructions instruct the hardware to: receive a network device selection message sent by a first network device, where the network device selection message contains a virtual local area network (VLAN) mapping capability identifier of the first network device and a device identifier of the first network device; when determining that both the apparatus and the first network device have VLAN mapping capability according to local VLAN mapping capability and the VLAN mapping capability identifier of the first network device, select a network device for executing VLAN mapping according to sizes or a sequence of a local device identifier and the device identifier of the first network device.

Abstract: A dielectric lens, where the dielectric lens is a cylindrical lens or an ellipsoidal lens whose cross-sectional profile is a quasi-ellipse, and the dielectric lens is formed by piling a plurality of units. Dielectric constant distribution of the units in the dielectric lens enables a non-plane wave in a minor axis direction of the quasi-ellipse to be converted into a plane wave through the dielectric lens. The units of the dielectric lens are prepared through extrusion, injection, molding, computer numerical control (CNC) machining, or a three dimensional (3D) printing process technology, and the units may be assembled through gluing, welding, structural clamping, or a coupling printed through 3D printing. When the dielectric lens is applied to a multi-beam antenna, a system capacity of a communications system can be increased. In addition, a thickness of the lens is reduced using the multi-beam antenna.
