Abstract: A user traffic generation method includes receiving a user traffic generation instruction, performing, in response to the user traffic generation instruction and index information pre-stored in an on-chip static random access memory (SRAM) of a field programmable gate array, a prefetch operation and a cache operation on a user packet that is stored in a dynamic random access memory DRAM and indicated by the index information, and generating user traffic at a line rate of the user packet that is cached during the cache operation. The on-chip SRAM is configured to store index information of all user packets that need to be used. The DRAM is configured to store all the user packets.

Abstract: A user traffic generation method is disclosed, the method includes: receiving a user traffic generation instruction; performing, according to the user traffic generation instruction and index information pre-stored in a first on-chip static random access memory SRAM of a field programmable gate array FPGA, a prefetch operation and a cache operation on a user packet that is stored in a dynamic random access memory DRAM and indicated by the index information, where the first on-chip SRAM is configured to store index information of all user packets that need to be used, and the DRAM is configured to store all the user packets; and generating user traffic according to a user packet that is cached during the cache operation. According to the embodiments of the present invention, storage of a mass of user packets can be implemented, and user traffic can be generated at a line rate.
