Abstract:
A method for configuring an address table in a field-programmable gate array (FPGA), an FPGA, and a network device applying the FPGA, where the FPGA includes k storage blocks, the k is greater than or equal to the two, and the FPGA is configured to obtain a key, where the key is generated based on a first packet of a data stream, and a length of the key is equal to a key bit width of the FPGA, obtain an index number corresponding to the key, where the index number is used to search for a forwarding entry of the data stream, divide the key into k sub-keys, where each of the k sub-keys corresponds to one of the k storage blocks, determine an address entry of each of the k sub-keys in a corresponding storage block, and write a storage address to the address entry based on the index number.

Claim (Index 18):
The network device of  claim 17 , wherein the processor is further configured to:\n receive a second packet of the data stream, the second packet being a subsequent packet of the first packet; generate the key based on the second packet; and send a search request to the FPGA, the search request comprising the key, and the FPGA being further configured to:\n receive the search request; \n divide the key into the k sub-keys; \n read, using each of the k sub-keys as an address, a storage address in an address entry in a storage block corresponding to a sub-key to obtain k storage addresses; \n perform an AND operation on the k storage addresses to obtain a target storage address; and \n generate the index number based on the target storage address.
