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: 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.

Abstract: This application provides a search apparatus, including a global dispatcher, a global arbiter, and N search engines. The N search engines can access a first search table. The global dispatcher is configured to: determine that a first search keyword is corresponding to the first search table and dispatch the first search keyword to the N search engines. Each search engine is configured to: search, according to a first search algorithm, one subtable to determine whether an entry that matches the first search keyword exists; and output a search result to the global arbiter. The global arbiter is configured to arbitrate the search result output by each search engine, to obtain a search result corresponding to the first search table.

Abstract: Embodiments of the present invention provide a method and an apparatus for generating a decision tree. The method includes generating an encoded rule set according to a rule set, generating a first weighted undirected graph, and calculating a weight of each side in the first weighted undirected graph. If a weight of a side with a maximum weight in the first weighted undirected graph is greater than a first threshold, a first operation is cyclically performed until a weight of a side with a maximum weight in a newly generated weighted undirected graph is less than or equal to the first threshold and a decision tree is generated for a rule subset corresponding to each vertex respectively in the newly generated weighted undirected graph.
