Abstract: A method and an apparatus for controlling packet transmission and a network functions virtualization (NFV) system, where the method includes determining, by a control device, at least two target service processing units and at least one associated service processing unit, where packets of a target service need to be transmitted to the at least two target service processing units through the at least one associated service processing unit, a first target service processing unit in the at least two target service processing units is configured to perform, on packets of the target service, service processing corresponding to a first software version, and a second target service processing unit in the at least two target service processing units is configured to perform, on packets of the target service, service processing corresponding to a second software version; and sending first control information according to a preset first threshold.

Abstract: An antenna unit and an antenna array. The antenna unit includes M layers of cross metal patches, M layers of dielectric substrates, and a metal ground layer, where M is an integer greater than 1. In addition, an ith-layer dielectric substrate is disposed between an ith-layer cross metal patch and an (i+1)th-layer cross metal patch. The ith-layer cross metal patch, the ith-layer dielectric substrate, and the (i+1)th-layer cross metal patch are sequentially stacked, and i is an integer ranging from 1 to M−1. An Mth-layer cross metal patch, an Mth-layer dielectric substrate, and the metal ground layer are sequentially stacked. The antenna unit and the antenna array formed by units may have a good polarization feature, a relatively wide operating bandwidth, and a relatively good phase shift feature.

Abstract: A service registration method and usage method, and a related apparatus are used to reduce risks generated when a service of an AP-type service providing node cannot be registered and a CP-type service providing node provides a service since distributed characteristics of a service providing node are not distinguished in a network partition scenario. The method is: obtaining, by a registration service node, network partition information, and receiving a registration request of a service providing node, where the registration request carries a distributed characteristic of the service providing node, and the distributed characteristic meets both consistency and partition tolerance, or meets both availability and partition tolerance; and determining, by the registration service node according to the network partition information and the distributed characteristic of the service providing node, whether registration of a service provided by the service providing node is allowed.
