Abstract: A network device management method and apparatus are provided. The method includes: generating statistical traffic data, where the statistical traffic data includes at least one of data traffic of a port of a network device, a queue status of the network device, traffic of a data packet that passes through the network device, or traffic of a target data flow that passes through the network device; and sending the statistical traffic data to a controller. The controller receives statistical traffic data sent by multiple network devices, and can adjust a path of a data flow dynamically according to a traffic status of each port of the multiple network devices or a traffic status of a transmitted data flow in the multiple network devices and by changing routing tables of the network devices, thereby improving link utilization, and further improving network performance.

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.
