Deep packet inspection method and apparatus, and coprocessor

摘要

Embodiments of the present invention provide a deep packet inspection method and apparatus, and a coprocessor. In the deep packet inspection method, the coprocessor transmission / reception module receives the original data packet transmitted by the general-purpose processor, transmits the original data packet to the processor core of the coprocessor, and the processor core receives the application layer analysis result. Invoking at least one sub-coprocessor of the coprocessor to perform application layer analysis on the original data packet to obtain, so that the processor core processes the original data packet according to the analysis result, Transmitting the analysis result to a general-purpose processor. The deep packet inspection method and apparatus provided by the embodiment of the present invention reduces the resource occupation of the general-purpose processor and improves the execution speed.
