Deep packet inspection method and apparatus, and coprocessor

摘要

Embodiments of the present invention provide a deep packet inspection method and device, and a coprocessor. The deep packet inspection method includes: receiving, by a transceiver module of the coprocessor, an original data packet sent by a general processor, and sending the original data packet to a processor core of the coprocessor; invoking, by the processor core, a sub-coprocessor of the coprocessor to perform application layer parsing on the original data packet, so as to obtain an application layer parsing resu and sending, by the processor core, the parsing result to the general processor, so that the general processor processes the original data packet according to the parsing result. The deep packet inspection method and apparatus provided by the embodiments of the present invention reduce resource occupation of a general processor and increase a running speed.
