Abstract: One example packet processing device includes a buffer, and the packet processing device obtains a to-be-measured packet. In response to determining that occupied storage space in the buffer is less than a preset threshold, the packet processing device reads the to-be-measured information from the buffer, and modifies, based on the to-be-measured information and a first algorithm, a pieces of data in first measurement data corresponding to the to-be-measured packet, where a is a positive integer. In response to determining that occupied storage space in the buffer is greater than or equal to a preset threshold, the packet processing device modifies, based on to-be-measured information and a second algorithm, w pieces of data in second measurement data corresponding to the to-be-measured packet, where w is a positive integer, and w is less than a.

Abstract: Disclosed is a packet processing method and system, and a device. A status value used to identify a topology status of service nodes at a specified time is preconfigured for a packet in a packet flow, so that when a service node in a next hop is selected for the packet, selection is performed not based on a topology status of current actual service nodes in the next hop, but based on the topology status, which is identified by the status value, of the service nodes at the specified time. As long as status values carried in packets in a same packet flow are the same, even if a topology status of service nodes changes, a same service node can still be selected for the packets in the same packet flow, thereby avoiding a problem of diversion of the packets in the same packet flow.

Abstract: The present application discloses data processing methods. Example methods include obtaining information about a header field of a data packet and searching an exact match flow table for an exact match entry that matches the data packet. When the matching exact match is found, a determination is made as to whether an update time of a wildcard entry corresponding to the exact match entry is before a creation time of the exact match entry. In response to determining that the update time is before the creation time of the exact match entry, the data packet is processed according to an action instruction corresponding to the exact match entry. In response to determining that the update time of the wildcard entry corresponding to the exact match entry is not before the creation time of the exact match entry, the exact match entry is deleted.

Abstract: Embodiments of this application provide a network flow control method and a network device. The method includes: receiving a packet flow; determining, based on a service type of the packet flow, a service pipeline used for transmitting the packet flow, where service types of all packet flows in the service pipeline are the same; and based on a bandwidth weight allocated to the service type, transferring the packet flow in the service pipeline to a physical port. In the embodiments of this application, packet flows are allocated to different service pipelines based on a service type, and bandwidth weights are allocated, in a centralized manner, to service pipelines that carry a same service type.
