    CPC classification number: H04L47/125

    Abstract: This application provides a load sharing method, a root node device, a leaf node device, and a system. The method includes: a first root node device receives a message sent by the leaf node device, where the message includes a first identifier and configuration information. The first identifier indicates the leaf node device. The configuration information indicates a configuration mode, requested by the leaf node device, of load sharing from a root node device group to the leaf node device. The root node device group includes the first root node device. The first root node device determines, based on the first identifier and the configuration information, a configuration result of the load sharing from the first root node device to the leaf node device.

    Abstract: A packet sending method and a related device are disclosed. The method includes: A network device obtains a first packet, where an internet protocol extension header of the first packet includes a first identifier, and the first identifier indicates a service requirement corresponding to the first packet. The network device determines, based on the first identifier and a second identifier, path indication information corresponding to the first packet, where a destination address of the first packet includes the second identifier, and the path indication information herein includes one or more of a network slice identifier and a segment identifier list. The network device updates the first packet based on the path indication information to obtain a second packet, and sends the second packet.

    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.
