Abstract: A packet forwarding method, system, and apparatus are provided. The method includes: determining that a total number of links is an integral power of 2, wherein the total number of links is a sum of a number of added virtual link and a number of actual links for forwarding a data packet; calculating a hash value of the data packet, and calculating a remainder of the hash value divided by the total number of links; and if the remainder corresponds to a virtual link, calculating another hash value of the data packet, returning back to the step of calculating a remainder, performing the above operations cyclically until the remainder corresponds to an actual link, and forwarding the data packet on the actual link.

Abstract: This application provides an instruction processing method and a chip. The method includes sending, by the thread unit, a search instruction to the search engine unit. The search instruction includes a data address and a first search field, and the thread unit switches from a RUN state to a WAIT state. The method also includes receiving, by the thread unit, data and a program counter that are sent by the search engine unit. The thread unit switches from the WAIT state to the RUN state.

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.
