    Abstract: Embodiments of the present invention provide a method and an apparatus for generating a decision tree. The method includes generating an encoded rule set according to a rule set, generating a first weighted undirected graph, and calculating a weight of each side in the first weighted undirected graph. If a weight of a side with a maximum weight in the first weighted undirected graph is greater than a first threshold, a first operation is cyclically performed until a weight of a side with a maximum weight in a newly generated weighted undirected graph is less than or equal to the first threshold and a decision tree is generated for a rule subset corresponding to each vertex respectively in the newly generated weighted undirected graph.

    Abstract: A data sending method, where the method includes receiving, by a forwarding device using a first flexible Ethernet (FlexE) group and in multiple timeslots included in a first timeslot set, multiple first encoded data blocks from a physical coding sublayer (PCS), determining, by the forwarding device according to the timeslots included in the first timeslot set and the first FlexE group, a second FlexE group and multiple timeslots included in a second timeslot set, and sending, by the forwarding device, the first encoded data blocks using the second FlexE group and in the timeslots included in the second timeslot set. The forwarding device does not need to process the first encoded data blocks in a conventional layer 2 or layer 3 forwarding mode. Therefore, a processing delay can be reduced, and a transmission delay can be reduced.

    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.
