Abstract: A packet forwarding method to shorten a transmission latency of an elephant flow is provided. In the method, for a first packet flow used as an elephant flow, a network device may receive a plurality of packets of the first packet flow, and determine a characteristic parameter of the first packet flow based on the plurality of packets, where the characteristic parameter of the first packet flow is used to indicate a transmission latency of the first packet flow. After determining the characteristic parameter of the first packet flow, the network device determines a forwarding policy of the first packet flow based on the characteristic parameter of the first packet flow. The forwarding policy of the first packet flow is used to indicate latency sensitivity of the first packet flow.

Abstract: A service flow scheduling method and apparatus, and a system. When transmission quality of a service flow with a higher priority does not meet a service level requirement corresponding to the service flow, a first network device adjusts, to a first threshold, a transmission rate threshold of an HQoS model for a service flow with a lower priority, where the first threshold is less than a current data transmission rate of the service flow with a lower priority. By performing traffic shaping on the service flow with a lower priority, a bandwidth resource of a downlink port of the first network device may give way to the service flow with a higher priority, to ensure that the service flow with a higher priority meets the service level requirement of the service flow with a higher priority.

Abstract: Embodiments of the present invention disclose a packet processing method and apparatus. A data format of a packet does not need to be understood before the packet is processed, which features high flexibility and commonality and facilitates rapid deployment of a new service. The method includes: acquiring, by a central processing unit CPU, a location parameter of a key and an identifier of a flow table, where the location parameter of the key is used to indicate a location of the key in a packet; acquiring, by the CPU, the key from the packet according to the location parameter of the key; searching, by the CPU according to the key and the identifier of the flow table, the flow table for a flow table entry that matches the key; and processing, by the CPU, the packet according to the flow table entry.

Abstract: Embodiments of the present invention provide a multi-frequency communications antenna and a base station. The multi-frequency communications antenna includes at least one low-frequency array, at least one high-frequency array, at least one circuit board disposed corresponding to the high-frequency array, and a reflection panel, where a filtering component configured to decouple filtering is disposed on the circuit board, a first end of the filtering component is electrically connected to the high-frequency array, and a second end of the filtering component is electrically connected to a signal ground layer of the circuit board. The filtering component configured to decouple filtering that is shown in this embodiment is disposed on the circuit board, which causes a small damage to an array radiation environment.
