Abstract: A route searching method and apparatus, an allocation node, a searching node, and an ingress node are provided. The method includes: receiving, by an allocation node, a destination IP address of a packet sent by an ingress node, where an allocation table on the allocation node includes a match item field and a searching node number field; performing, by the allocation node, matching of the match item field in the allocation table according to the destination IP address in an LPM principle; if the destination IP address successfully matches a first match item field in the allocation table, obtaining, by the allocation node, a physical box number of a first searching node on which routing information of a first prefix subtree corresponding to the first match item field is located; and sending, by the allocation node, the destination IP address to the first searching node.

Abstract: This application provides for data transmission between first and second network devices. The first network device requests information from the second network device and in return receives grant information from the second network device. The grant information includes at least a first sequence number that is used by the first network device to determine a first credit limit, where the first credit limit is an amount of data allowed to be sent by the first network device in a packet-distributed load sharing manner. The first network device sends data to the second network device based on the first credit limit. Second and third sequence numbers are also described.

Abstract: This application relates to the field of storage technologies and discloses a content addressable memory, a data processing method, and a network device, to resolve a problem that an existing CAM has a relatively large area, and consumes relatively large power. The CAM includes bit units of M rows and N columns, each bit unit includes a first FeFET and a second FeFET, a source of the first FeFET is connected to a drain of the second FeFET, a source of the second FeFET is grounded, bit cells of a same column correspond to a same match line, and a drain of a first FeFET in each bit cell of a same column is connected to a match line corresponding to the column. Bit cells of a same row correspond to a same first bit line and a same second bit line, a gate of a first FeFET in each bit cell of a same row is connected to a first bit line corresponding to the row, and a gate of a second FeFET in each bit cell of a same row is connected to a second bit line corresponding to the row. The CAM may be applied to a network device such as a router.
