Abstract: A path detection method in a virtual extensible local area network (VxLAN), a controller, and a network device, where the controller constructs a detection packet according to a detection request and sends the detection packet to a source network device corresponding to a source VxLAN tunnel endpoint (VTEP). The source network device forwards, level by level, the detection packet to a destination network device corresponding to a destination VTEP, and reports information such as an Internet Protocol (IP) address, an outbound interface number, and an inbound interface number to the controller level by level. Therefore, a real service path may be detected.

Abstract: A radio remote unit, including a unit body, and multiple heat dissipation fins that are disposed on a surface of the body, where an opening groove is disposed on the heat dissipation fin, and opening grooves on the multiple heat dissipation fins form a fan ventilation groove, where the fan ventilation groove is connected to ventilation channels between the heat dissipation fins, and a fan is disposed in a built-in manner in the fan ventilation groove. The fan ventilation groove formed by the opening grooves on the multiple heat dissipation fins is connected to the ventilation channels between the heat dissipation fins, and the fan is disposed, which implements that in a case in which a quantity of heat dissipation fins is unchanged, the fan performs air cooling on the radio remote unit, effectively improving a heat dissipation capability.
