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: A faulty link detection method includes receiving statistical data that is reported by all nodes every preset quantity of packets that carry a program clock reference value. All the nodes collect statistical data starting from a unified program clock reference value. The quantity of packets lost between an upstream node and a downstream node among all the nodes is acquired according to the statistical data. A faulty link is determined according to the quantity of packets lost between the upstream node and the downstream node.

Abstract: A method and a device for classifying a packet, in the field of communications technologies, are provided to reduce rule duplication in a classification process and improve classification efficiency. The method classifies a packet by receiving a packet; searching for a rule matching the packet in at least one created decision tree (created after an original rule set is divided based on a segmentation code); and classifying the packet according to a found rule. The method and the device may be applicable to a router.
