    Abstract: The embodiments of the present invention relate to a routing table establishment method and device and a routing table lookup, method and device. The routing table establishment method includes: partitioning a data structure of a routing table into a trunk and a TRIE sub-tree (101); adding entries of the routing table to the TRIE sub-tree (102); and storing an upgrade sub-node of the TRIE sub-tree's root in the trunk, where the height of the TRIE sub-tree is smaller than or equal to a set height threshold (103), and the upgrade sub-node of the TRIE sub-tree's root is a sub-root among prefix sub-nodes included in the TRIE sub-tree's root. Thereby ensuring the high compression ratio of the routing table; and the height of the TRIE sub-tree is controlled according to the height threshold, thereby reducing times for accessing a memory, improving lookup speed, and reducing lookup delay.

    Abstract: A method includes receiving, by a forwarding device, M pieces of description information that are sent by a controller and are in a one-to-one correspondence with M forwarding services. Each piece of description information includes preset performance of a corresponding forwarding service and an identifier of a table to be searched, and a set including preset performance of the M forwarding services includes Q elements. The method further includes generating Q pieces of simultaneous access information according to the M pieces of description information; and determining, according to the Q pieces of simultaneous access information, that N tables are to be stored in at least one memory of the forwarding device.

    Abstract: A packet forwarding method to shorten a transmission latency of an elephant flow is provided. In the method, for a first packet flow used as an elephant flow, a network device may receive a plurality of packets of the first packet flow, and determine a characteristic parameter of the first packet flow based on the plurality of packets, where the characteristic parameter of the first packet flow is used to indicate a transmission latency of the first packet flow. After determining the characteristic parameter of the first packet flow, the network device determines a forwarding policy of the first packet flow based on the characteristic parameter of the first packet flow. The forwarding policy of the first packet flow is used to indicate latency sensitivity of the first packet flow.

    Abstract: A memory management method includes: determining that available storage space of a first memory in a network device is less than a first threshold, where the first threshold is greater than 0 and the first memory stores a first packet queue; and deleting at least one packet at the tail of the first packet queue from the first memory based on the available storage space of the first memory being less than the first threshold. When the available storage space of the first memory is less than the first threshold, a packet queue, namely, the first packet queue, is selected and a packet at the tail of the packet queue is deleted from the first memory.
