    Abstract: This application provides a packet forwarding method and a related apparatus. The method includes: determining whether a flow to which a packet belongs meets a large flow condition; and if the flow to which the packet belongs meets the large flow condition and a flowlet routing table does not include a flowlet entry corresponding to the flow, creating the corresponding flowlet entry in the flowlet routing table, and forwarding the packet based on the created flowlet entry. In the foregoing technical solution, a corresponding flowlet entry may be created only for a large flow, to perform flowlet-based load balancing on the large flow. This can reduce an entry resource used for flowlet-based load balancing, improve balance of multi-path load sharing, and effectively improve a traffic sharing effect of load balancing.

    Abstract: An arrayed waveguide grating includes an input/output waveguide 1, an input/output waveguide 2, a slab waveguide, an arrayed waveguide 1, a reflection zone 1, an arrayed waveguide 2, and a reflection zone 2. The input/output waveguide 1 and the input/output waveguide 2 are located on a same side of the slab waveguide, and are coupled to the slab waveguide. The reflection zone 1 is configured to reflect a light wave in a first band, and to transmit a light wave in a second band. The reflection zone 2 is configured to reflect the light wave in the second band. It is implemented that a single arrayed waveguide grating outputs light waves with different adjacent channel wavelength spacings, and a quantity of devices used in a system in which an uplink adjacent channel wavelength spacing and a downlink adjacent channel wavelength spacing are asymmetrical is further reduced.

    Abstract: This application provides a traffic classification method and apparatus. The method includes: determining, based on distribution characteristics of concerned bits of a plurality of rules in a first rule set, an effective bit corresponding to the first rule set; determining a hash key value of each rule based on a value of the effective bit of each rule in the first rule set, and storing each rule in the first rule set in at least one of S storage units based on the hash key value, where the first rule set is any one of N rule sets, the N rule sets are stored in the S storage units; and when traffic classification is performed, searching for a corresponding rule in each of the S storage units based on a hash key value of a search key.

    Abstract: Embodiments of this application disclose a traffic monitoring method and apparatus, an integrated circuit, and a network device. When the traffic monitoring apparatus receives a packet, after determining that the traffic monitoring apparatus includes an empty first register, the traffic monitoring apparatus updates a value of first information in the first register to a measured value of a target performance indicator of the packet, and increases a value of second information in the first register by 1. The value of the second information in the first register is 0, the first information in the first register indicates a depth of a data bucket that carries a measured value of the target performance indicator of a to-be-monitored packet, and the second information in the first register indicates a quantity of packets that are in received packets and that match the value of the first information in the first register.
